气体增压泵常见故障分析及处理办法

气体增压泵如果不能正常工作，有如下几种可能:

驱动活塞密封伯磨损，导致活塞上侧和下侧串气;

Gas booster pump if it does not work, there are several possible:

Sealing job wear of piston driven, causing the piston upper and lower side hernia;

控制阀损坏，导致换向阀不能正常工作;

换向阀太脏，或它的密封件损坏，导致它不能动作;

Control valve damage, lead to the valve does not work;

Reversing valve is too dirty, or the seal is damaged, leading to not move;

两活塞连接处损坏，开口销脱落，两活塞杆错位，导致活塞杆不能移动;

The two piston pin joint damage, loss, two piston rod dislocation, causes the piston rod can not move;

在工作中有进会出现这种情况:需增压气体被断开，却开着增压泵，增压泵噪声也很大。此进气体增压泵工作频率很高，压力却无法加上去，增压泵噪声也很大。长时间这样工作，很容易损坏泵。同样道理，当增压泵出口压力很低时，增压泵工作频率会很高，增压泵也容易损坏。

In the work with a will appear this kind of circumstance: the need for booster gas is disconnected, but open the booster pump, booster pump noise is also great. The inlet gas booster pump working frequency is high, the pressure is not added, the booster pump noise is also great. Long time like this, it is easy to damage the pump. Similarly, when the pressure pump outlet pressure is very low, the booster pump working frequency will be high, a booster pump is easy to damage.

在实际工作中级连气体增压泵出现过这种特殊情况:卸压阀V5不断卸压，增压泵1频率很快，增压泵2频率低，仔细检查后发现V5设定值偏小，调高设值后，出现可调压力开关阀V6大量放气。后来确认是增压泵1有问题。原来该增压泵1的控制阀V2上侧与管道2连通，没有断开。因此增压泵1不断增压，不爱V6控制。换句话说，该泵与设计图纸要求型号一样，但是它少装了一个小零件及气路客道堵头，从而导致工作不正常。这个零件应该安装在泵内，因此不易发现。为了使该设备能够正常工作，采取了的方法:将增压泵1进气的截止球阀进气量关小，从而降低了增压泵1的工作频率，使泵组维持正常工作。彻底解决则是装上该堵头。

Had this special case in practical work intermediate even gas booster pump: V5 constant pressure relief valve pressure relief, pressure pump 1 frequency quickly, booster pump 2 frequency is low, after careful examination found that V5 setting value is small, increase the set value, the adjustable pressure valve appeared V6 deflation. It was later confirmed the booster pump 1 problems. The booster pump control valve 1 V2 side and pipe 2 connected, no disconnection. Therefore the booster pump 1 continuous pressure, don"t love V6 control. In other words, the pump and the design requirements of the drawings models, but it installed a few small parts and pneumatic gate plug, resulting in not working properly. This part should be installed in the pump, so it is not easy to find. In order to enable the device to work properly, take a method: cut-off valve air intake booster pump 1 inlet off small, thereby reducing the booster pump working frequency 1, the pump to maintain the normal working group. Solve is installed on the plug.

还有一种特殊情况:增压泵2突然停止工作，总压力也上不去了。在现场检查，发现它的换向阀V3被顶信不能动弹。于是关了增压泵组的压缩空气，卸下V3时，发现V3的阀心被一股气往处弹出。原来导致V3的阀心不能运动是因为该阀右端有压强，没有卸压。之所以没有卸压是因为活塞停在了中间位置，没有碰开控制阀V1。导致活塞停在中间有三个原因:

气体增压泵1出现异常造成增压泵2进气口压国过大;

气体增压泵2有两个增压气缸，工作时是双向压缩，双向行程都需要提供驱动;活塞在静止状态下启动时静摩擦力大。装回换向阀V3，打开压缩空气重新启动，泵组工作正常解决这种故障还有一个办法，就是关掉压缩空气，让高压气体出口压强降到3Mpa左右，再重新启动泵组。
