摘　　要：PSA装置解析气压缩机因发现振动大和异常声音而停机,检修完毕后出现一级右列做功差的现象,结合两次试机过程,并逐项排查各影响因素后,判断为气阀本身密封面失效导致吸入性能变差。结合本次检修的拆解情况,从工艺流程和气阀改型两方面提出应对措施,以期为相关研究提供参考。The PSA device analyzed that the gas compressor was shut down due to excessive vibration and abnormal sound,and after maintenance,there was a phenomenon of poor power output in the first stage right column.Based on two test runs and a thorough investigation of various influencing factors,it was determined that the poor suction performance was caused by the failure of the sealing surface of the gas valve itself.Based on the disassembly situation of this maintenance,countermeasures are proposed from two aspects:process flow and valve modification,in order to provide reference for relevant research.
