1 .泵不工作
1. pumps do not work.
a. 检查驱动气源是否开启,驱动压力是否满足要求
A. check whether the driving gas source is turned on and whether the driving pressure meets the requirements.
b. 检查缸盖气路是否畅通
B. check whether cylinder head gas path is clear.
c. 检查换向阀气路是否畅通
C. check whether the valve of the reversing valve is clear.
2 .泵动作突然加快,驱动活塞不到头就换向
2., the pump action is suddenly accelerated, and the piston is driven to change direction.
a. 检查换向阀端的撞针孔是否变成了常通孔
A. check whether the pinhole of the end of the reversing valve has turned into Chang Tongkong.
b. 检查换向阀高压腔是否泄漏
B. check whether high pressure chamber of leakage valve leaks.
c. 检查控制气管是否泄漏
C. check to control leakage of trachea.
3 .泵动作缓慢
3. slow pump action
a. 检查驱动气通路是否受阻
气体增压泵
A. check whether the drive gas passage is blocked.
b. 检查控制气通路是否受阻
B. check to check if gas passage is blocked.
d. 检查驱动活塞的密封是否泄漏
D. check whether the seal of the driving piston is leaking.
4 .达到设定压力或保压一段时间后,不停泵
4., after setting pressure or holding pressure for a period of time, the pump will not stop.
a. 检查控制气通路是否泄漏,主要检查撞针、换向阀阀芯的密封
A. check to control whether the gas path is leaked, mainly check the sealing of the spool and the spool of the reversing valve.
