气液增压泵在使用一段时间后会出现增压泵不工作或者上压慢等故障。现在小编就将气液增压泵常见的几种故障通过表现来分析出现这种情况的原因和解决方法告诉大家。
After using the gas-liquid booster pump for a period of time, the booster pump will not work or the pressure will be slow. Now Xiaobian will analyze the causes and solutions of several common faults of gas-liquid booster pump through performance.
1.故障表现：当驱动气液压力不低于20psi时，驱动部分不工作或不循环。
1. Fault performance: when the driving gas-liquid pressure is not less than 20psi, the driving part does not work or does not cycle.
可能原因：供气管路堵塞或供气量不足;空气循环阀堵塞;排放口结冰;消声器堵塞。
Possible causes: the air supply pipeline is blocked or the air supply is insufficient; The air circulation valve is blocked; The discharge port is frozen; The muffler is blocked.
解决方法;检查气液供应管道和空气调压阀;拆卸空气循环阀，并使用允许溶剂进行清洗;驱动气液水含量较高，改用更好的干燥设备;将消声器拆卸下来清洗。
resolvent; Check the gas-liquid supply pipeline and air pressure regulating valve; Disassemble the air circulation valve and clean it with permitted solvent; The water content of the driving gas-liquid is high, so better drying equipment should be used; Disassemble the muffler for cleaning.
2.故障表现：在负载情况下，驱动部分不工作，并在换向排气口有连续气液排出。
2. Fault performance: under load, the driving part does not work, and there is continuous gas-liquid discharge at the reversing exhaust port.
可能原因：换向针的弹簧破坏或不适合;换向针末端O型圈不适合或失去作用。
Possible causes: the spring of the reversing needle is damaged or unsuitable; The O-ring at the end of the reversing needle is not suitable or loses its function.
解决方法;置换弹簧;置换O型圈。
resolvent; Displacement spring; Replace the O-ring.
3.故障表现：驱动部分不工作;消声器泄露空气。
3. Fault performance: the driving part does not work; The silencer leaks air.
可能原因：驱动气液流量不足;空气循环阀芯的密封收缩或损坏。
Possible cause: insufficient driving gas-liquid flow; The seal of the air circulation valve core shrinks or is damaged.
解决方法;提高驱动气液流量;检测空气循环阀芯的密封，如果损坏，更换并组装重新测试;如果没有损坏，检查驱动部分密封。
resolvent; Increase the drive gas-liquid flow; First, check the seal of the air circulation valve element. If it is damaged, replace it, assemble it and retest it; If there is no damage, check the drive part seal.
4.故障表现：驱动部分工作，但气液没有增压。
4. Fault performance: the driving part works, but the gas and liquid are not pressurized.
可能原因：气液压缩部分的单向阀密封或高压部分损坏。
Possible cause: the one-way valve seal or high-pressure part of the gas-liquid compression part is damaged.
解决方法;检查单向阀及高压端。
resolvent; Check the check valve and high-pressure end.
What should we pay attention to when selecting the gas-liquid booster pump system?
1、确定自己的现场驱动气压与被增压介质的进口压力。
1. Determine your own on-site driving air pressure and the inlet pressure of the pressurized medium.
2、了解自己所需的高运用压力、及工装的常用压力。
2. Know the high operating pressure you need and the common pressure of tooling.
3、别的对自己现场运用的工况也要有一个清晰的知道、比如说流量的需求。往往流量是一个气液增压能否被客户运用的一个重要因素。
3. In addition, you should also have a clear understanding of the working conditions used on site, such as the flow demand. Often, flow is an important factor for whether a gas-liquid pressurization can be used by customers.
