Valve failure and exhaust temperature
Thread Content
Two-stage compression reciprocating compressor, with liquid in the first cylinder, producing knocking sounds. After a series of drainage operations, it was found that the pressure at the outlet and the inlet 2 decreased, the temperature at the outlet dropped, and the air injection volume also reduced. I think the outlet valve below the cylinder has failed due to water hammer, becoming stuck and allowing air leakage. Although valve leakage and repeated compression cause the exhaust temperature to rise, this is not enough to offset the effect of the reduced compression ratio, and it cannot convince others. Please share your valuable opinions.
It’s probably because the drain valve wasn’t closed properly, causing air leakage! If the primary exhaust valve is leaking, the pressure ratio will increase and the temperature will rise! !
