Abstract:

In this paper, the influence of factors such as process parameters, leakage fault and flow regulation on the interstage pressure of reciprocating compressors is analyzed by theoretical analysis and case verification. Based on the practical situations, the active control plans of “general bypass regulation”, “step by step bypass regulation” and stepless capacity regulation system for the interstage pressure of reciprocating compressors are discussed, providing some guidance for the analysis of interstage pressure variation of reciprocating compressors.
