What are the common problems with CNG reciprocating compressors? How to deal with it?
They are all reciprocating compressors; only the working medium differs. Let’s talk about some common issues. The parts prone to failure include: first, leakage problems caused by high temperatures of the air valves, which require replacement of those valves ； The second issue is a fault in the piston assembly; pressure builds up in a certain section of the cylinder, so it is necessary to replace the piston rings or the piston itself ； Third is the failure of the transmission components
The working principle is the same; only the process medium differs； A common issue is overpressure in a certain section; check the outlet check valve ； The outlet pressure is low; check the inlet check valve or piston rings ； No pressure can be applied; check the inlet and outlet check valves as well as the piston rings ； Vibration is too high; check the transmission mechanism ； There is a knocking sound in the cylinder; check whether liquid has entered the cylinder, as this liquid could originate from the gas-liquid separation tank or the cooler.
