Liquid in the compressor has a greater impact on the inlet or outlet valve
The presence of liquid in reciprocating compressors has a significant impact on both the inlet and outlet valve plates, accelerating and exacerbating valve damage; however, due to the higher outlet pressure, the impact on the outlet valve is greater. Centrifugal compressors operating with liquid can experience accelerated impeller damage due to the impact of liquid droplets ； This post was last edited by Longsky Eagle on 2009-2-25 14:02.]
The inlet of the reciprocating machine must not contain liquid; methods such as adjusting the process gas (to cool and separate liquids from gases) and draining liquid at the compressor inlet should be employed promptly. In fact, it is the cylinder that has the greatest impact on the compressor; severe liquid presence can lead to liquid slugging against the cylinder ； Damage to the inlet and outlet valve plates can be tolerated, but if the cylinders collide with each other, the consequences can be quite serious. Additionally, pressure has little effect on the gas valve; the opening and closing of the valve disc are achieved by the spring force on both sides of the disc and the gas pressure difference ； So, it has a greater impact on the exhaust valve leaf! The reason is not high pressure, but rather high exhaust temperature@!
If there is very little liquid present, it has little impact on the cylinder, but the valve plates of the air valves are prone to breaking!
Centrifugal – damages the impeller.
Piston compressors still have a significant impact on the cylinders. If liquid slugging occurs, it will damage the piston rod and crosshead. It can cause impacts on the valve plates, similar to hail in a storm, leading to damage to those plates.
