对气体增压泵停止运行问题的解决方案

今天针对气体增压泵停止运行问题,进行检查,未发现问题原因,仍无法运行。

检测内容如下:

1.驱动进气检测。

2.监测管线检查。

3.增压泵缸体检查。

4.驱动气换向阀检查。

驱动进气检查:

①将2#GCU增压泵切换到问题增压泵,确认:增压泵进出气管线阀门打开,驱动 气阀门打开,监测管线阀门打开。投用驱动气(仪表风@6bar),增压泵未动作。
① Switch the 2 ? GCU booster pump to the problem booster pump, and confirm that: the inlet and outlet gas pipeline valve of booster pump is opened, the driving gas valve is opened, and the monitoring pipeline valve is opened. When the driving gas (instrument air @ 6bar) was put into operation, the booster pump did not operate.
②拆下four-way valve(换向阀)后,打开驱动管线阀门,有明显气体进入。说明驱动气管线正常。
② After removing the four way valve, open the drive line valve and there is obvious gas entering. It indicates that the driving gas pipeline is normal.
2.监测管线检查:通入工艺气及氮气后,监测气变送器示值未发生变化。

3.缸体检查:据用户供的信息,增压泵停止工作前,声音异常,明显高于正常工作时。  经询问没有听到金属摩擦的声音。现场未发现缸体因活塞摩擦产生变形或颜色变化。

4.驱动气换向阀检查:

拆下换向阀之后,检查未发现被污染痕迹。酒精清洗后回装。回装过程中手指驱动 换向阀芯,没有明显卡滞感觉,阀芯运行平顺。
