Air booster pump plays an important role in the daily production of the industry, so what is its principle? What are the reasons for the failure and how to deal with it?
空气增压泵原理
Principle of air booster pump
空气增压泵又称
气体增压泵，是由大面积活塞端的低压气体驱动，在小面积活塞端产生高压流体。可用于压缩空气等气体，通过驱动气压可无级调节输出气压。用于原气压系统需要升压的工作环境，可用于提升压力、阀校准、阀门和井口装置的水鼓泡试验、气压调节器、加压空气等气体的检测。
The air booster pump, also known as the gas booster valve, is driven by the low-pressure gas at the large-area piston end to produce high-pressure fluid at the small-area piston end. It can be used for compressed air and other gases. The output air pressure can be adjusted steplessly by driving the air pressure. It is used in the working environment where the pressure of the original air pressure system needs to be boosted. It can be used for pressure lifting, safety valve calibration, water bubbling test of valves and wellhead devices, detection of gas such as air pressure regulator and pressurized air.
空气增压泵的工作原理是利用压缩空气作为动力源，根据大面积活塞的低压推动，将其转化为活塞面积小的高压气体。增压比是活塞面积的比值，它决定了输出压力。
The working principle of the air booster pump is to use compressed air as the power source and convert it into high-pressure gas with small piston area according to the low-pressure push of the large-area piston. The boost ratio is the ratio of piston area, which determines the output pressure.
气体增压泵适用于原气压系统需要增压的工作环境，可将工作系统气压提高数倍。该泵不适用于高纯气体的增压，出厂气路输出压力=增压比×进气压力，一般不高于1。0MPa。
The gas booster pump is suitable for the working environment where the original air pressure system needs to be pressurized, and can increase the air pressure of the working system several times. The pump is not applicable to the pressurization of high-purity gas. The output pressure of the factory gas circuit = pressurization ratio × Intake pressure, generally not higher than 1. 0MPa。
因此，在以下情况下，可使用气体增压泵提供少量局部高压气体。气路中的个别或部分装置需要高压。当工厂主气路压力下降，不能保证气动装置的工作压力时，利用增压泵提供高压气体，以维持气动装置的正常工作。不能配置大直径气缸，但必须保证输出力。
Therefore, the gas booster pump can be used to provide a small amount of local high-pressure gas in the following cases. Individual or partial devices in the gas circuit require high pressure. When the pressure of the main air circuit of the factory drops and the working pressure of the pneumatic device cannot be guaranteed, the booster pump is used to provide high-pressure gas to maintain the normal operation of the pneumatic device. Large diameter cylinders cannot be configured, but the output force must be guaranteed.

Troubleshooting of inoperative air booster pump
如何解决空气增压泵不工作的问题？要了解增压泵不工作的原因，找出增压泵不工作的原因后再分析总结。本文将简要介绍空气增压泵不工作的解决方法。
How to solve the problem that the air booster pump does not work? To understand the reason why the booster pump does not work, find out the reason why the booster pump does not work, and then analyze and summarize. This paper will briefly introduce the solution to the non operation of the air booster pump.
原因包括：换向阀脏污或密封损坏，使热水增压泵无法正常运转。两活塞接头损坏，开口销脱落，两活塞杆错位，使活塞杆不能正常运动。密封处发生漏气。
The reasons include: the change-over valve is dirty or the seal is damaged, which makes the hot water booster pump unable to operate normally. The two piston joints are damaged, the cotter pin falls off, and the two piston rods are misaligned, making the piston rod unable to move normally. Air leakage at the seal.
磨损和带动活塞密封圈，使活塞上、下两面有漏气现象。增压泵不工作的原因及解决方法1、单向阀泄漏。增压后的水压不会倒流，压力会下降，这是单向阀的作用。漏水是单向阀密封质量问题，达不到设定值，也会导致循环增压泵不工作。
Wear and drive the piston sealing ring, so that there is air leakage on the upper and lower sides of the piston. Causes and solutions of booster pump not working 1. Check valve leakage. The pressurized water pressure will not flow back and the pressure will drop, which is the function of the check valve. Water leakage is a problem of the sealing quality of the check valve. If the set value is not reached, the circulating booster pump will not work.
解决方案：先将空气增压泵调规定值，并做标记，然后关闭增压泵电源，观察指针是否会下降。如果它下降，则意味着有漏水。如果没有压力表，关机一段时间后，可以打开水龙头，看看水压是否明显下降。
Solution: first adjust the air booster pump to the specified value and mark it, then turn off the power supply of the booster pump and observe whether the pointer will drop. If it drops, it means there is water leakage. If there is no pressure gauge, turn on the faucet after shutting down for a period of time to see if the water pressure drops significantly.
也可能是停机压力值太高。如果停机压力设置高，管道增压泵将达不到规定值。仔细检查相应的压力值。解决方法：如果有指针压力表，可以先不停机先看指针压力值，做好标记。再次检查停机压力值，适当调整设定压力值。
It may also be that the shutdown pressure value is too high. If the shutdown pressure is set high, the pipeline booster pump will not reach the specified value. Carefully check the corresponding pressure value. Solution: if there is a pointer pressure gauge, you can look at the pointer pressure value and mark it without stopping the machine. Check the shutdown pressure value again and adjust the set pressure value appropriately.
