摘　　要：考虑到往复式压缩机固有的机械振动特性,为了保证压缩机组在海洋平台上的稳定运行,采用平面波动理论和转移矩阵法,分析压缩机管道系统的气流脉动和管道振动,对管路、进口洗涤罐、缓冲罐及换热器等进行设计优化,有效避免了压缩机管道系统在不同操作工况下的气柱和管路机械共振问题,实现了在设计阶段对压缩机振动问题进行有效控制的目的。Considering the inherent mechanical vibration characteristic of the reciprocating compressor,in order to ensure the stable operation of the compressor unit on offshore platform,gas pulsation and piping vibration for the compressor piping system were analyzed by using the plane wave theory and transfer matrix method.The design optimization of piping,suction scrubber,pulsation bottles and heat exchanger can prevent the issue of gas column and piping mechanical resonance of compressor piping system under different operating conditions.The compressor vibration issue is effectively controlled in the design stage.
