Piston compressor stage 3 failure
Thread Content
The piston compressor has pressure buildup at the second stage; the pressure at the third stage does not rise and remains similar to that of the second stage. The temperature of the air valves in all stages is low, with no temperature detected at the third stage. May I ask what the fault is?
Check whether the pipelines for secondary discharge and tertiary suction are blocked? A low temperature means no work is being done! Also, how should I understand the statement that \"there is pressure at level 2, but pressure cannot be reached at level 3; it’s roughly the same as the pressure at level 2\"? If the third-stage pressure cannot be achieved, how can there be second-stage backpressure?
The secondary pressure can be brought within the control range, but the tertiary pressure cannot be increased. Today I removed the third-stage exhaust valve; there was no problem with it
Check the third-stage piston ring; it cannot be drawn in at the third stage.
The third-stage pressure is synchronized with the second-stage pressure; it’s definitely a problem with the third-stage valve, so it needs to be replaced
