摘　　要：气流脉动是伴随往复压缩机的工作的一种特殊现象,是往复压缩机管道振动主要原因。同时在往复压缩机使用过程中需要经常进行气量调节,包括驱动机变频、压开吸气阀、可变余隙容积、回路阀组调节等多种方式,各种调节方式对气流脉动也存在不同程度的影响。Air pulsation is a special phenomenon accompanying the work of reciprocating compressors,which is the main reason for the vibration of reciprocating compressor pipeline.At the same time,the reciprocating compressor needs to be adjusted frequently during the using process,including the frequency conversion of driver,the pressure opening of suction valve,the variable clearance volume,and the loop valve group adjustment.Various adjustment methods also have different degrees of impact on air flow pulsation.
