Different Valves in Air Compressors – Functions & Malfunctions Well Explained

As a complex mechanical equipment, the compressor is composed of hundreds of different parts in an orderly combination. The smooth and efficient operation of the compressor depends on the sound operation and organic cooperation of various components, especially key components, and valves are one of them.

Due to different compression types, different design ideas, and different brands, the types of valves required in compressors are also different. Although it is not possible to summarize all compressor valves, we can select the important types to make a summary.

Eight Typical Valves in Air Compressors

Whether you are an air compressor sales person, or mechanical maintenance staff member, or a purchaser for your factory, you should have heard or very familiar with the following 7 famous valves in air compressors:

  1. Intake Valve
  2. Minimum Pressure Valve/MPV
  3. Safety Valve
  4. Temperature Control Valve
  5. Oil Cut Valve
  6. Check Valve
  7. Solenoid Valve
  8. Regulating Valve

01 Intake Valve (Unloader or Loading Valve)

The intake valve is the breathing port of the air compressor. The ordinary air enters the intake valve and then goes to the compressor head, where it is compressed to produce compressed gas. It can control the loading and unloading of the air compressor and the size and flow of the air pressure. It is a main component (intake control system) on the air compressor.

The working principle of the intake valve, the intake control valve is mainly composed of a valve body, a valve, a piston, a cylinder, a spring, a sealing ring, etc. It is equipped with a control block and a control solenoid valve on its side, which integrates on-off adjustment, load reduction, and dissipation. Sound, depressurization, and shutdown and vent functions. When unloading, a small part of the gas is released through the small hole in the valve to balance the intake air volume of the small hole of the intake control valve, so that the pressure in the separation oil tank is maintained at 0.2-0.3MPa, and the normal air compressor oil is maintained. cycle. The opening and closing action of the intake control valve is automatically controlled by the pressure sensor and solenoid valve of the regulating system. Whether the opening and closing action of the intake control valve is flexible is very important to the reliability of the screw machine.

What are the failures of the intake valve usually? The failure of the air valve is generally that the screw machine does not unload and the intake valve is not closed. If it is not loaded, the solenoid valve of the intake valve is damaged. The screw machine is injecting oil, and the valve body control block is faulty. The screw compressor is overloaded, and the intake valve is opened early when starting. Therefore, the intake control valve should be replaced with maintenance kits regularly to maintain good working conditions. During each maintenance, the parts must be removed to check the wear of each friction surface. Special attention should be paid to the surface of the rubber sealing ring. If there is damage or cracks, new parts must be replaced. After the repair kit is replaced, the parts should be replaced. Clean, the friction surface of the metal parts should be coated with lubricating oil.

Generally, the manual of the air compressor manufacturer stipulates that the intake valve repair kit should be replaced at 8000 hours, but in order to reduce the cost, some users basically do not maintain according to the service cycle. They are all repaired after the intake valve fails. It is recommended to delay the replacement time according to the specified time before the failure occurs. After all, the use environment of each screw compressor is different, but it is best to control it. Replace within a reasonable range.

02 Minimum Pressure Valve – MPV

The minimum pressure valve, also known as the pressure maintenance valve, is located at the outlet above the oil-gas separator. It is composed of valve body, valve core, spring, sealing ring, adjusting screw, etc.

The function of the minimum pressure valve in the compressor is as follows: the cycle pressure necessary for lubrication is quickly established when the equipment is started to avoid the equipment from being worn due to poor lubrication; it acts as a buffer to control the gas flow rate through the oil-gas separation filter element to prevent high-speed airflow damage The oil and gas separation effect brings the lubricating oil out of the system to avoid the excessive pressure difference between the two sides of the oil and gas separation filter element from damaging the filter material; the non-return function has the function of a one-way valve. When the compressor stops working or enters the no-load state, the pressure in the oil and gas barrel drops, and the minimum pressure valve can prevent the gas from the gas storage tank from returning to the oil and gas barrel.

Common malfunctions:

There are many compressor failures caused by the minimum pressure valve, mainly as follows: the cylinder safety valve jets during operation, this failure is because the minimum pressure valve is not opened, resulting in excessive pressure, safety valve pressure relief protection; motor during operation Overload protection, because the minimum pressure valve is not opened, the pressure is too high, the motor is overloaded, and the thermal relay protects the shutdown; the compressor fails to start, and the minimum pressure valve is not closed tightly, resulting in the return of compressed air in the pipe network, and the startup failure under pressure; when unloading The oil pressure is high and the energy consumption increases. Because the minimum pressure valve is not tightly closed, the compressed air of the pipe network returns when the unit is unloaded, which causes the pressure in the compression chamber to rise and the oil pressure rises.

The reasons for the improper closing, damage and failure of the minimum pressure valve are: poor air quality or external impurities entering the unit, impurity particles driven by the high-pressure airflow, impact the minimum pressure valve, causing damage to the minimum pressure valve components, or Dirt is trapped between the sealing surfaces, causing the minimum pressure valve to fail; the compressor is filled with too much oil, and too much lubricating oil will form oil viscosity in the minimum pressure valve, causing the valve plate to close or open; the minimum pressure valve is based on a specific Depending on the design of the working conditions, if the working conditions fluctuate greatly or deviate from the design value for a long time, the minimum pressure valve will quickly fail; when the compressor is stopped for a long time and then turned on, the moisture contained in the lubricating oil and air will be inside the equipment unit. Accumulate, corrode various parts of the minimum pressure valve, and form oil viscosity.

03 Safety Valve

The safety valve is also called the overflow valve, which plays a role of safety protection in the compressor system. When the system pressure exceeds the specified value, the safety valve opens to discharge part of the gas in the system into the atmosphere, so that the system pressure does not exceed the allowable value, so as to ensure that the system does not cause accidents due to excessive pressure.

The common faults of safety valves are as follows:
(1) Gas leakage or failure to start. Insufficient airtightness is mostly caused by the lack of maintenance for the compressor for a long time, and the surface of the accessories is too dirty or worn, and should be cleaned and replaced in time. Another possibility that cannot be started is that the settings are inaccurate.

(2) Constant vibration. The matching spring is not suitable, the stiffness is improper, and it needs to be adjusted.
Compressor safety valves belong to the category of automatic valves. According to the “Safety Valve Safety Technical Supervision Regulations”, the regular verification of safety valves is generally at least once a year. The formal safety valve calibration methods include: off-line calibration of the calibration platform, online instrument calibration, and step-up jump method validation. It can also be checked by a simple method, that is, when the compressor is working with full load, gently open the valve cover, if the safety valve can exhaust outward, it is regarded as normal. High-temperature oil mist will be brought out when the safety valve is vented outwards, so pay attention to safety.

04 Temperature Control Valve

The function of the temperature control valve is to control the exhaust temperature of the machine head. Its working principle is that the temperature control valve core adjusts the oil passage formed between the valve body and the housing through expansion and contraction according to the principle of thermal expansion and contraction. Control the proportion of lubricating oil entering the oil cooler to ensure that the rotor temperature is within the set interval.
When the exhaust temperature of the machine head is too low, moisture will precipitate in the oil and gas barrels, causing the lubricating oil to emulsify. When the cold machine starts, the temperature control valve forces the lubricating oil directly into the machine head without passing through the oil cooler. When the oil temperature rises to a certain value, the temperature control valve completely opens the passage through the oil cooler. At this time, all the lubricating oil is cooled by the oil cooler and then sprayed into the machine head.

Since the lubricating oil entering the temperature control valve is not filtered, the internal passage of the temperature control valve is more complicated, which is easy to cause dirt accumulation. After long-term use, the failure rate of the temperature control valve is relatively high, which often leads to high temperature protection of the machine. In addition, after the temperature control valve completely opens the passage through the oil cooler, it cannot completely cut off the passage of hot oil directly into the machine head. The temperature of the lubricating oil entering the machine head is always higher than the outlet temperature of the oil cooler, resulting in low cooling efficiency. Therefore, some manufacturers’ models do not have a temperature control valve, and control the oil temperature by controlling the start and stop of the fan motor. When the exhaust temperature of the machine head rises to 90°C, the fan starts to run. If the temperature is lower than 70°C, the fan stops. , Keep the temperature within a certain range.

By checking the four oil pipes connected with the temperature control valve, it can be judged whether the temperature control valve is working normally. The four oil pipes are: oil barrel to temperature control valve, temperature control valve to oil cooler, oil cooler to temperature control valve, and temperature control valve to oil filter; normal temperatures are: high, high, low, slightly higher .

05 Oil Cut Valve / Oil Stop Valve

The oil cut-off valve is a switch used to control the main oil path into the screw head. Its function is to cut off the oil supply to the main engine when the compressor is stopped, so as to prevent the lubricating oil from spraying out of the main engine port, and the oil backflow occurs at the moment of shutdown.

Common malfunctions:

During the use of the compressor, a small part of the impurities in the air will inevitably be mixed into the cooling oil, which may cause sedimentation and blockage when flowing through the oil cutoff valve, so that the oil cutoff valve cannot be opened with the opening of the equipment. In the closed or semi-closed state, the cooling oil flow is reduced, which seriously affects the cooling effect of the machine head, causing rapid high temperature trip after starting up, high temperature alarm or back spray of lubricating oil when shutting down.

Therefore, users need to clean and maintain the oil shut-off valve regularly, optimize the compressor operating environment, use it in an environment with good ventilation and heat dissipation, away from volatile gases, debris and floating debris, and replace the air filter in strict accordance with the pressure difference parameter requirements.

06 Check Valve or One-Way Valve

One-way valve is also called check valve, commonly known as one-way valve. In the compressed air system, it is mainly used to prevent the compressed oil and gas mixture from being suddenly back-injected into the main engine when the machine is shut down due to a sudden failure, causing the rotor to reverse rotation.

One-way valve sometimes fails to close tightly. The main reasons are: the rubber sealing ring of the one-way valve falls off, the spring is broken, the spring and the rubber sealing ring need to be replaced; there is a foreign body supporting the sealing ring, and the impurities on the sealing ring need to be cleaned.

07 Solenoid valve

Sullair Compressor Solenoid Part

Genuine-Sullair-unloading-solenoid-valve-25038-666-screw-air-compressor-part

The solenoid valve belongs to the control system, including a loading solenoid valve and a vent solenoid valve. In the compressor, the solenoid valve is mainly used to adjust the bias, flow, speed, on-off and other parameters of the medium.

(1) Load solenoid valve

The loading solenoid valve is a two-position three normally closed solenoid valve, which controls the oil and gas barrel to the intake valve to perform the on and off of the cylinder pipeline under the instruction of the PLC. When the loading solenoid valve is energized, the compressed air in the oil and gas tank is allowed to enter the intake valve actuator cylinder, and the intake port is opened. When the loading solenoid valve loses power, it cuts off the passage from the oil and gas barrel to the intake valve execution cylinder, vents the gas in the execution cylinder, and closes the intake port.

(2) Vent the solenoid valve

The vent solenoid valve is a two-position, two-position solenoid valve, whose diameter must match that of the intake bypass valve. The diameter of the vent solenoid valve and the intake bypass valve should be able to ensure that the pressure in the oil and gas barrel is about 0.2MPa when the compressor is empty. When the compressor is unloaded and stopped, the vent solenoid valve loses power and releases the gas in the oil and gas tank to the intake filter.

Common malfunctions:

  • a. The solenoid valve terminal is loose or the thread terminal is dropped. The solenoid valve must not be energized, and the thread terminal can be tightened to solve the problem.
  • b. The solenoid valve is leaking. Air leakage will result in a lack of air pressure, making it difficult to open and close the valve. The reason is that the sealing gasket is damaged or the slide valve is worn to form blow-by.
  • c. The solenoid valve coil is burnt out. If the solenoid valve coil is burned out, the wiring of the solenoid valve can be removed and measured with a multimeter. If it is open, the solenoid valve coil is burned out.
  • d. The solenoid valve is stuck. The cooperation gap between the slide valve sleeve of the solenoid valve and the valve core is very small, and it is usually installed as a single piece. When mechanical impurities are brought in or there is too little lubricating oil, it is easy to get stuck.

Disposal method: Use a steel wire to poke into the small hole in the head to make it rebound. The complete solution is to remove the solenoid valve, take out the valve core and valve core sleeve, and clean, so that the valve core moves sensitively in the valve sleeve. When disassembling, pay attention to the installation sequence of the components and the orientation of the external wiring, so that the reinstallation and wiring are correct. Also check whether the oil spray hole of the lubricator is blocked and whether the lubricating oil is satisfactory.

08 The last but not the least: Compressed Air Pressure Regulating Valve – Regulator

Regulate-Air-Compressor through the regulating valve When you operate an air compressor, the success of your project depends largely on the pressure of the air itself. To get the proper pressure for each application, you need to make sure that the settings are correct. In order to make these adjustments and make sure that you have indeed made the correct settings, there is a function called the air compressor pressure regulating valve.

One of the most important components of an air compressor is the pressure regulator, which controls the air flow through the system. Without this type of control function, the pressure and intensity of the air flowing from the compressor tank into the pneumatic tool cannot be adjusted. The regulator protects each tool from too high or too low power, thereby helping to ensure the quality of pneumatic applications.

Why adjust the air compressor?

Air pressure regulators are important because different types of pneumatic tools require different pressure levels. If you try to power a slow-moving tool with the same pressure required for fast-moving operations, you may overwhelm the tool. If you do the opposite, the latter operation may produce plain results.

Air-Compressor Pressure Regulator Vavlejpg

When you adjust the air compressor, you can reduce the energy required to run pneumatic operations. Without the function of a pressure regulator, you may consume a lot of energy in each working day to meet peak demand, even if only a small part of the application requires so much energy. Essentially, there are three reasons to adjust your air compressor: to properly service your pneumatic tools, simplify applications, and save energy.

        Atlas Copco Air Compressor Oil Shut-off (Oil Cut Off) Valve

        Welcome to import genuine Atlas Copco Oil-cut valves from China distributor. Chengdu Pudding Mechatronic Co. CPMC is a direct distributor of world class Air Compressors, OEM parts and aftermarket replacement. Based in China, with our own network and working closely with domestic and international top brands like Atlas Copco, Ingersoll Rand, Sullair, Quincy, CP, Jaguar, etc, we are proud to offer better prices (5-10% cheaper than on Alibaba).

        Brand: All models of Atlas oil cut-off valves are available
        Accessory type: valve
        Accessory part number: Available, choose according to your needs
        Accessories use: cut off the main engine oil supply to prevent the air compressor from spraying oil after the air filter
        Applicable air compressor model: Atlas Copco Rotary screw air compressors

        Atlas Copco Air Compressor Oil Shut-off Valve working principle

        When the compressor is working, the generated compressed air will open the oil shut-off valve, and the cooling oil can circulate in the system to cool the head screw. When the air compressor is not working, the spool of the oil cut-off valve is closed by the spring tension, so that the cooling oil in the oil-air separator cannot return to the screw.

        Atlas Copco Air Compressor Oil Shut-off Valve common malfunction

        During the use of the equipment, a small part of the impurities in the air will inevitably be mixed into the cooling oil, which may cause sedimentation and blockage when passing through the oil cutoff valve, so that the oil cutoff valve cannot be opened with the opening of the equipment, and is closed or closed. The semi-closed state will reduce the flow of cooling oil. Therefore, the cooling effect of the screw head will be seriously affected.

        Daily maintenance for Atlas Copco Air Compressor Oil Shut-off Valve

        We need to clean the shutoff valve regularly. In order to make the oil cutoff valve work normally, the impurities in the air mixed into the oil will also affect the temperature control valve and the oil filter. Therefore, we need to start from the source of the problem:
        1. The air filter is replaced strictly in accordance with the pressure difference parameters to minimize the air impurities entering the screw.
        2. Try to optimize the use environment of the equipment.

        Why is it So Important to have Temperature Control Valve for Air Compressor?

        The temperature control valve of the screw air compressor is installed between the machine head and the oil and gas separation barrel, on the side of the oil filter. The temperature control valve has a total of three oil pipes, one is connected to the oil and gas separation barrel, one is connected to the oil filter, and the other is connected to the cooler. When the lubricating oil comes in, according to the oil temperature, the valve core will automatically expand and contract, so that the lubricating oil enters the oil filter for filtering or enters the cooler for cooling. What are the consequences if the screw air compressor does not require a temperature control valve and does not install it?

        What harm will the screw air compressor have if there is no temperature control valve?

        1. The temperature control valve of the air compressor plays a role of thermostatic control. If the temperature control valve is missing, it will cause the air compressor to trip at high temperature.

        2. The temperature control valve is a component that controls the flow of lubricating oil. If the action is not in place, the temperature of the unit may be too high or too low.

        3. Without a temperature control valve, the temperature of the air compressor lubricating oil will rise after working, and the high-temperature oil will circulate to the lubrication system for continued use. The oil temperature will continue to rise, speeding up the deterioration of the oil, increasing the equipment load and friction loss Seriously, shorten the life of the equipment; increase the work of the cooler, increase the power consumption, increase the operating cost, and waste energy.

        If the screw air compressor is not equipped with a temperature control valve, it will cause a lot of problems, which will seriously affect the performance and working conditions of the air compressor. The cost required is more than the cost of the temperature control valve. If you are looking original thermal valve, learn more “Genuine Thermostat Valve by Reliable China Distribution Network“.

        10 Minutes to Quickly Understand the 5 Key Valves of the Air Compressors

        Air compressors have different valves, and each valve has a different function and purpose. If you have a thorough understanding of the design function and working principle of each valve, it will be better for the future inspection and maintenance of air compressors. Here Chengdu Pudding Mechatronic Co. CPMC provide the critical advice to help you understand the common faults and principles of the 5 key valves in air compressor system.

        Because the valve has a certain service life, when the use time reaches the limit that the valve can withstand, it is inevitable that the valve will fail, so how should we avoid it?

        The five major valve parts of the fuel injection air compressor are: Unloading valve, Min pressure valve, Oil stop valve, Check valve (One way valve) and Thermostatic valve. Let’s interpret each valve function and troubleshooting one by one.

        A. Unloading valve function

        When the gas consumption changes, the intake valve adjusts the opening degree of the valve body through the control system to match the gas consumption. It is a valve that controls the air compressor to produce and not produce gas.

        Common corresponding faults:

        1. The air compressor is not loaded. This fault control panel displays (no alarm; the operating state is loaded, the fuel injection pressure is very small or 0’; the machine head outlet temperature is less than 70C° to determine the machine
        The group is not loaded. The problem lies in the unloading valve body, control circuit, loading and unloading solenoid valve and other parts, which need to be checked and eliminated one by one.

        2. The air compressor is not unloaded. This fault control panel displays (no alarm; operating status’unloading; fuel injection pressure rise>4; head outlet temperature>80°C) to determine the machine
        The group is not uninstalled. The problem lies in the unloading valve body, control circuit, loading and unloading solenoid valve, etc., which need to be checked and eliminated one by one.

        B. Minimum pressure valve

        Function:
        1. The opening pressure of the minimum pressure valve is about 4 bar, to ensure that the pressure in the cylinder is not lower than this minimum pressure when the air is output, so as to avoid excessive air flow rate causing oil and gas separation.
        The separation effect of the separator is reduced.

        2. When the machine starts, a certain pressure is established in the oil cylinder to ensure the circulation of lubricating oil and provide the initial control pressure for the control loop.

        3. It has the function of a one-way valve to prevent the compressed air of the pipe network from returning to the inside of the machine.

        Common corresponding faults

        1. The safety valve of the oil cylinder sprays air during operation. This failure is because the minimum pressure valve is not opened, which causes the pressure in the cylinder to be too high, and the safety valve is pressure-relief protection.

        2. Motor overload protection occurs when the computer is running. This fault is that the minimum pressure valve is not opened, which causes the pressure in the cylinder to be too high, the main motor load increases, the current increases, and the thermal relayThe protector shuts down.

        3. The air compressor failed to start. This failure is that the minimum pressure valve is not closed tightly, causing the compressed air of the pipe network to return, causing a certain pressure in the oil cylinder, causing the unit to fail to start.
        verb: move. When the air compressor is started, when the control computer detects a certain pressure in the cylinder, the unit will not be able to start.

        4. The oil pressure is too high when the air compressor is unloaded. This fault is that the minimum pressure valve is not closed tightly. When the unit is unloaded, the compressed air of the pipe network will flow back, which will increase the pressure in the cylinder and cause the oil pressure to rise.
        High, the energy consumption of the unit increases.

        C. Oil cut-off valve

        Function:
        After the air compressor is turned on, the oil cut-off valve is opened, and the lubricating oil that has passed through the oil filter is injected into the main engine. After the compressor is shut down, the oil cut-off valve is closed to cut off the oil supply.

        Common corresponding faults:

        1. The machine will jump to high temperature quickly after starting up. This fault is that the oil cut-off valve is not opened and the lubricating oil cannot be sprayed into the machine head. The oil cut-off valve needs to be checked and maintained.

        2. High temperature alarm of air compressor. This fault is that the oil cut-off valve is not fully opened, and the amount of lubricating oil sprayed into the machine head is insufficient, and the oil cut-off valve needs to be cleaned and maintained.

        3. When the machine stops suddenly, the lubricating oil will be sprayed back into the air filter. This fault is caused by the lagging or lax closing of the shutoff valve when the unit suddenly shuts down. The shutoff valve needs to be cleaned and maintained.

        D. Check valve

        Function:
        The oil and gas mixture compressed by the main engine is unidirectionally delivered to the oil cylinder to prevent the oil and gas mixture in the cylinder from being sprayed back into the machine head when the machine fails suddenly, causing the rotor to reverse.

        Common corresponding faults:

        When the machine is stopped, the oil and gas mixture is sprayed back into the air filter. This fault is caused by the one-way valve stuck or damaged when the unit suddenly shuts down, and the one-way valve needs to be cleaned and maintained.

        E. Temperature control valve

        Function:

        1. The temperature control valve core uses the principle of thermal expansion and contraction to adjust the oil passage formed between the valve body and the shell by extending and contracting, and controls the proportion of lubricating oil entering the oil cooler to ensure rotation. The sub-temperature is within the control range.

        2. The temperature control valve is an original part that controls the outlet temperature of the machine head to be no less than 68. When the oil temperature is low, the temperature control valve is closed, and the lubricating oil is directly sprayed into the machine head to be quickly heated without passing through the cooler. The temperature at the outlet of the machine head can be increased rapidly to prevent the condensed water in the compressed air from being generated in the oil cylinder.

        Note:
        1. The opening temperature of the thermostatic valve is generally indicated on the valve core.
        2. The maximum opening temperature of the thermostatic valve is the marked temperature + 15°C.

        空压机上的电磁阀基础知识

        空气压缩机中的电磁阀具有广泛的用途。 电磁阀数量和种类繁多意味着它们几乎可以涵盖任何类型的流体或材料应用。 在本博客中,成都沛丁机电设备有限公司将讨论空压机上的电磁阀基础知识以及电磁阀在空气压缩机中的一些用途。

        电磁阀是流体学中最常用的控制元件。他们的任务是关闭、释放、计量、分配或混合流体。它们存在于许多应用领域。电磁阀提供快速安全的切换、高可靠性、长使用寿命、所用材料的良好介质兼容性、低控制功率和紧凑设计。

        空气压缩机 – Air Compressor

        空压机是用于生产压缩空气的机器。 它由一台由电动机提供动力的活塞式压缩机、一台冷干机和一个储气罐组成。 它的工作原理是空气压缩:从大气中抽取空气,经压缩机压缩后收集到一个罐中。 进气口处装有过滤器,以防止异物进入气缸盖。 冷却盘管去除压缩空气加热产生的冷凝水。

        在电磁阀的应用过程中,电磁阀必须处于常开工作状态。 对于小流量,推荐使用直接作用型 RD236(连接 1/4″)和 RB214,因为它们专门用于常开操作。对于大流量,使用先导式电磁阀,如 RB203 型(带有商业连接) 3/8”)推荐。

        当系统运行时,电动机运行压缩机,压缩机吸入过滤后的空气,对其进行压缩,将其送到冰箱,最后送到水箱。 在此阶段,电磁阀通电并关闭电路,使其保持在压力下。 当油箱达到要求的压力读数时,压力开关停止电机,单向阀将空气保持在油箱内。 为了防止压缩机在压力下保持太久而损坏,电磁阀然后断电,它允许排出仍然在回路中的多余空气。

        RB203型
        RD236 型,带系列 7 线圈
        2/2路NO直动电磁阀
        RB214 型,串联 2 个线圈
        2/2路NO直动电磁阀
        RB203 型,串联 2 个线圈
        2/2路常开先导电磁阀

        电磁阀的不同之处在于它们使用的电流特性、它们产生的磁场强度、它们用来调节流体的机制以及它们控制的流体的类型和特性。该机构从线性动作、柱塞式致动器到枢转电枢致动器和摇臂致动器不等。阀门可以使用双端口设计来调节流量或使用三端口或更多端口设计在端口之间切换流量。多个电磁阀可以一起放置在一个歧管上。阀体必须与流体相容;常见的材料有黄铜、不锈钢、铝和塑料。而且密封件必须与流体兼容。

        为了简化密封问题,螺帽、芯、弹簧、遮光环和其他组件经常暴露在流体中,因此它们也必须兼容。这些要求提出了一些特殊的问题。芯管必须是非磁性的,才能将螺线管的磁场传递到螺帽和芯。螺帽和芯需要具有良好磁性能的材料,例如铁,但铁容易腐蚀。可以使用不锈钢,因为它们有磁性和非磁性两种。例如,电磁阀可能使用 304 不锈钢阀体、305 不锈钢芯管、302 不锈钢弹簧和 430 F不锈钢(用于磁芯和螺帽的磁性不锈钢)。

        Air Compressors Bypass Valve - Hot Air valve

        What is the Hot Air Bypass Valve of an Air Compressor? Why We Need It?

        In the post-processing equipment of the screw air compressor, the main function of the refrigeration dryer is to reduce the temperature of the compressed air, purify the compressed air, and remove the water vapor contained in it. So as to ensure the quality of compressed air and prevent damage to the equipment used. Low temperature is detrimental to many equipment, and the same is true for refrigeration dryers. With the help of hot air bypass valve, the dryer can be operated at an optimal temperature.

        Why Air Compressor Refrigeration Dryer Needs a Hot Air Bypass Valve

        So, what is a hot gas bypass valve? The hot gas bypass is a valve that automatically adjusts the cooling temperature in the drying exchanger based on the refrigeration pressure. The pressure measured after the heat exchanger is directly related to the temperature in the system.

        When the air handling capacity of the refrigeration dryer decreases, the evaporator cooling capacity is too large. When the evaporator cavity temperature drops below 0°C, the condensed water will freeze, resulting in “ice blockage” and blockage of the air circuit , The dryer cannot work. In order to eliminate the above situation, the air compressor’s refrigeration and dryer needs to introduce a hot gas bypass valve to cause high temperature and high pressure gas from the compressor, effectively preventing the occurrence of “ice blocking”.

        In addition to the reduction in air handling capacity that can cause “ice blockage”, the ambient temperature and the drainage condition of the dryer can also cause “ice blockage”.

        How to Choose an Effective Air Compressor Bypass Valve?

        It is important to select a hot gas bypass valve that can be fully opened and closed according to the pressure input. When the load is particularly low, a hot gas bypass valve with poor opening capability is unlikely to prevent freezing.

        The compressed air system is a whole, which requires air compressors, air storage tanks, refrigeration dryers, precision filters, etc. to cooperate with each other to play their respective performance roles in order to obtain high-quality compressed air that meets the production process.

        Different Valves in Air Compressors – Functions & Malfunctions Well Explained

        As a complex mechanical equipment, the compressor is composed of hundreds of different parts in an orderly combination. The smooth and efficient operation of the compressor depends on the sound operation and organic cooperation of various components, especially key components, and valves are one of them.

        Due to different compression types, different design ideas, and different brands, the types of valves required in compressors are also different. Although it is not possible to summarize all compressor valves, we can select the important types to make a summary.

        Eight Typical Valves in Air Compressors

        Whether you are an air compressor sales person, or mechanical maintenance staff member, or a purchaser for your factory, you should have heard or be very familiar with the following 8 famous valves types in air compressors:

        1. Intake Valve
        2. Minimum Pressure Valve/MPV
        3. Safety Valve
        4. Temperature Control Valve
        5. Oil Cut Valve
        6. Check Valve
        7. Solenoid Valve
        8. Regulating Valve

        01 Intake Valve (Unloader or Loading Valve)

        The intake valve is the breathing port of the air compressor. The ordinary air enters the intake valve and then goes to the compressor head, where it is compressed to produce compressed gas. It can control the loading and unloading of the air compressor and the size and flow of the air pressure. It is a main component (intake control system) on the air compressor.

        The working principle of the intake valve, the intake control valve is mainly composed of a valve body, a valve, a piston, a cylinder, a spring, a sealing ring, etc. It is equipped with a control block and a control solenoid valve on its side, which integrates on-off adjustment, load reduction, and dissipation. Sound, depressurization, and shutdown and vent functions. When unloading, a small part of the gas is released through the small hole in the valve to balance the intake air volume of the small hole of the intake control valve, so that the pressure in the separation oil tank is maintained at 0.2-0.3MPa, and the normal air compressor oil is maintained. cycle. The opening and closing action of the intake control valve is automatically controlled by the pressure sensor and solenoid valve of the regulating system. Whether the opening and closing action of the intake control valve is flexible is very important to the reliability of the screw machine.

        What are the failures of the intake valve usually? The failure of the air valve is generally that the screw machine does not unload and the intake valve is not closed. If it is not loaded, the solenoid valve of the intake valve is damaged. The screw machine is injecting oil, and the valve body control block is faulty. The screw compressor is overloaded, and the intake valve is opened early when starting. Therefore, the intake control valve should be replaced with maintenance kits regularly to maintain good working conditions. During each maintenance, the parts must be removed to check the wear of each friction surface. Special attention should be paid to the surface of the rubber sealing ring. If there is damage or cracks, new parts must be replaced. After the repair kit is replaced, the parts should be replaced. Clean, the friction surface of the metal parts should be coated with lubricating oil.

        Generally, the manual of the air compressor manufacturer stipulates that the intake valve repair kit should be replaced at 8000 hours, but in order to reduce the cost, some users basically do not maintain according to the service cycle. They are all repaired after the intake valve fails. It is recommended to delay the replacement time according to the specified time before the failure occurs. After all, the use environment of each screw compressor is different, but it is best to control it. Replace within a reasonable range.

        02 Minimum Pressure Valve – MPV

        The minimum pressure valve, also known as the pressure maintenance valve, is located at the outlet above the oil-gas separator. It is composed of valve body, valve core, spring, sealing ring, adjusting screw, etc.

        The function of the minimum pressure valve in the compressor is as follows: the cycle pressure necessary for lubrication is quickly established when the equipment is started to avoid the equipment from being worn due to poor lubrication; it acts as a buffer to control the gas flow rate through the oil-gas separation filter element to prevent high-speed airflow damage The oil and gas separation effect brings the lubricating oil out of the system to avoid the excessive pressure difference between the two sides of the oil and gas separation filter element from damaging the filter material; the non-return function has the function of a one-way valve. When the compressor stops working or enters the no-load state, the pressure in the oil and gas barrel drops, and the minimum pressure valve can prevent the gas from the gas storage tank from returning to the oil and gas barrel.

        Common malfunctions:

        There are many compressor failures caused by the minimum pressure valve, mainly as follows: the cylinder safety valve jets during operation, this failure is because the minimum pressure valve is not opened, resulting in excessive pressure, safety valve pressure relief protection; motor during operation Overload protection, because the minimum pressure valve is not opened, the pressure is too high, the motor is overloaded, and the thermal relay protects the shutdown; the compressor fails to start, and the minimum pressure valve is not closed tightly, resulting in the return of compressed air in the pipe network, and the startup failure under pressure; when unloading The oil pressure is high and the energy consumption increases. Because the minimum pressure valve is not tightly closed, the compressed air of the pipe network returns when the unit is unloaded, which causes the pressure in the compression chamber to rise and the oil pressure rises.

        The reasons for the improper closing, damage and failure of the minimum pressure valve are: poor air quality or external impurities entering the unit, impurity particles driven by the high-pressure airflow, impact the minimum pressure valve, causing damage to the minimum pressure valve components, or Dirt is trapped between the sealing surfaces, causing the minimum pressure valve to fail; the compressor is filled with too much oil, and too much lubricating oil will form oil viscosity in the minimum pressure valve, causing the valve plate to close or open; the minimum pressure valve is based on a specific Depending on the design of the working conditions, if the working conditions fluctuate greatly or deviate from the design value for a long time, the minimum pressure valve will quickly fail; when the compressor is stopped for a long time and then turned on, the moisture contained in the lubricating oil and air will be inside the equipment unit. Accumulate, corrode various parts of the minimum pressure valve, and form oil viscosity.

        03 Safety Valve

        The safety valve is also called the overflow valve, which plays a role of safety protection in the compressor system. When the system pressure exceeds the specified value, the safety valve opens to discharge part of the gas in the system into the atmosphere, so that the system pressure does not exceed the allowable value, so as to ensure that the system does not cause accidents due to excessive pressure.

        The common faults of safety valves are as follows:
        (1) Gas leakage or failure to start. Insufficient airtightness is mostly caused by the lack of maintenance for the compressor for a long time, and the surface of the accessories is too dirty or worn, and should be cleaned and replaced in time. Another possibility that cannot be started is that the settings are inaccurate.

        (2) Constant vibration. The matching spring is not suitable, the stiffness is improper, and it needs to be adjusted.
        Compressor safety valves belong to the category of automatic valves. According to the “Safety Valve Safety Technical Supervision Regulations”, the regular verification of safety valves is generally at least once a year. The formal safety valve calibration methods include: off-line calibration of the calibration platform, online instrument calibration, and step-up jump method validation. It can also be checked by a simple method, that is, when the compressor is working with full load, gently open the valve cover, if the safety valve can exhaust outward, it is regarded as normal. High-temperature oil mist will be brought out when the safety valve is vented outwards, so pay attention to safety.

        04 Temperature Control Valve

        The function of the temperature control valve is to control the exhaust temperature of the machine head. Its working principle is that the temperature control valve core adjusts the oil passage formed between the valve body and the housing through expansion and contraction according to the principle of thermal expansion and contraction. Control the proportion of lubricating oil entering the oil cooler to ensure that the rotor temperature is within the set interval.
        When the exhaust temperature of the machine head is too low, moisture will precipitate in the oil and gas barrels, causing the lubricating oil to emulsify. When the cold machine starts, the temperature control valve forces the lubricating oil directly into the machine head without passing through the oil cooler. When the oil temperature rises to a certain value, the temperature control valve completely opens the passage through the oil cooler. At this time, all the lubricating oil is cooled by the oil cooler and then sprayed into the machine head.

        Since the lubricating oil entering the temperature control valve is not filtered, the internal passage of the temperature control valve is more complicated, which is easy to cause dirt accumulation. After long-term use, the failure rate of the temperature control valve is relatively high, which often leads to high temperature protection of the machine. In addition, after the temperature control valve completely opens the passage through the oil cooler, it cannot completely cut off the passage of hot oil directly into the machine head. The temperature of the lubricating oil entering the machine head is always higher than the outlet temperature of the oil cooler, resulting in low cooling efficiency. Therefore, some manufacturers’ models do not have a temperature control valve, and control the oil temperature by controlling the start and stop of the fan motor. When the exhaust temperature of the machine head rises to 90°C, the fan starts to run. If the temperature is lower than 70°C, the fan stops. , Keep the temperature within a certain range.

        By checking the four oil pipes connected with the temperature control valve, it can be judged whether the temperature control valve is working normally. The four oil pipes are: oil barrel to temperature control valve, temperature control valve to oil cooler, oil cooler to temperature control valve, and temperature control valve to oil filter; normal temperatures are: high, high, low, slightly higher .

        05 Oil Cut Valve / Oil Stop Valve

        The oil cut-off valve is a switch used to control the main oil path into the screw head. Its function is to cut off the oil supply to the main engine when the compressor is stopped, so as to prevent the lubricating oil from spraying out of the main engine port, and the oil backflow occurs at the moment of shutdown.

        Common malfunctions:

        During the use of the compressor, a small part of the impurities in the air will inevitably be mixed into the cooling oil, which may cause sedimentation and blockage when flowing through the oil cutoff valve, so that the oil cutoff valve cannot be opened with the opening of the equipment. In the closed or semi-closed state, the cooling oil flow is reduced, which seriously affects the cooling effect of the machine head, causing rapid high temperature trip after starting up, high temperature alarm or back spray of lubricating oil when shutting down.

        Therefore, users need to clean and maintain the oil shut-off valve regularly, optimize the compressor operating environment, use it in an environment with good ventilation and heat dissipation, away from volatile gases, debris and floating debris, and replace the air filter in strict accordance with the pressure difference parameter requirements.

        06 Check Valve or One-Way Valve

        One-way valve is also called check valve, commonly known as one-way valve. In the compressed air system, it is mainly used to prevent the compressed oil and gas mixture from being suddenly back-injected into the main engine when the machine is shut down due to a sudden failure, causing the rotor to reverse rotation.

        One-way valve sometimes fails to close tightly. The main reasons are: the rubber sealing ring of the one-way valve falls off, the spring is broken, the spring and the rubber sealing ring need to be replaced; there is a foreign body supporting the sealing ring, and the impurities on the sealing ring need to be cleaned.

        07 Solenoid valve

        Sullair Compressor Solenoid Part

        Genuine-Sullair-unloading-solenoid-valve-25038-666-screw-air-compressor-part

        The solenoid valve belongs to the control system, including a loading solenoid valve and a vent solenoid valve. In the compressor, the solenoid valve is mainly used to adjust the bias, flow, speed, on-off and other parameters of the medium.

        (1) Load solenoid valve

        The loading solenoid valve is a two-position three normally closed solenoid valve, which controls the oil and gas barrel to the intake valve to perform the on and off of the cylinder pipeline under the instruction of the PLC. When the loading solenoid valve is energized, the compressed air in the oil and gas tank is allowed to enter the intake valve actuator cylinder, and the intake port is opened. When the loading solenoid valve loses power, it cuts off the passage from the oil and gas barrel to the intake valve execution cylinder, vents the gas in the execution cylinder, and closes the intake port.

        (2) Vent the solenoid valve

        The vent solenoid valve is a two-position, two-position solenoid valve, whose diameter must match that of the intake bypass valve. The diameter of the vent solenoid valve and the intake bypass valve should be able to ensure that the pressure in the oil and gas barrel is about 0.2MPa when the compressor is empty. When the compressor is unloaded and stopped, the vent solenoid valve loses power and releases the gas in the oil and gas tank to the intake filter.

        Common malfunctions:

        • a. The solenoid valve terminal is loose or the thread terminal is dropped. The solenoid valve must not be energized, and the thread terminal can be tightened to solve the problem.
        • b. The solenoid valve is leaking. Air leakage will result in a lack of air pressure, making it difficult to open and close the valve. The reason is that the sealing gasket is damaged or the slide valve is worn to form blow-by.
        • c. The solenoid valve coil is burnt out. If the solenoid valve coil is burned out, the wiring of the solenoid valve can be removed and measured with a multimeter. If it is open, the solenoid valve coil is burned out.
        • d. The solenoid valve is stuck. The cooperation gap between the slide valve sleeve of the solenoid valve and the valve core is very small, and it is usually installed as a single piece. When mechanical impurities are brought in or there is too little lubricating oil, it is easy to get stuck.

        Disposal method: Use a steel wire to poke into the small hole in the head to make it rebound. The complete solution is to remove the solenoid valve, take out the valve core and valve core sleeve, and clean, so that the valve core moves sensitively in the valve sleeve. When disassembling, pay attention to the installation sequence of the components and the orientation of the external wiring, so that the reinstallation and wiring are correct. Also check whether the oil spray hole of the lubricator is blocked and whether the lubricating oil is satisfactory.

        08 The last but not the least: Compressed Air Pressure Regulating Valve – Regulator

        Regulate-Air-Compressor through the regulating valve When you operate an air compressor, the success of your project depends largely on the pressure of the air itself. To get the proper pressure for each application, you need to make sure that the settings are correct. In order to make these adjustments and make sure that you have indeed made the correct settings, there is a function called the air compressor pressure regulating valve.

        One of the most important components of an air compressor is the pressure regulator, which controls the air flow through the system. Without this type of control function, the pressure and intensity of the air flowing from the compressor tank into the pneumatic tool cannot be adjusted. The regulator protects each tool from too high or too low power, thereby helping to ensure the quality of pneumatic applications.

        Why adjust the air compressor?

        Air pressure regulators are important because different types of pneumatic tools require different pressure levels. If you try to power a slow-moving tool with the same pressure required for fast-moving operations, you may overwhelm the tool. If you do the opposite, the latter operation may produce plain results.

        Air-Compressor Pressure Regulator Vavlejpg

        When you adjust the air compressor, you can reduce the energy required to run pneumatic operations. Without the function of a pressure regulator, you may consume a lot of energy in each working day to meet peak demand, even if only a small part of the application requires so much energy. Essentially, there are three reasons to adjust your air compressor: to properly service your pneumatic tools, simplify applications, and save energy.
