摘　　要：蓄能器是衰减往复泵出口流量脉动的常用设备。文章通过建立蓄能器和管路系统数学模型,利用共振衰减理论常用的分布参数法,通过传递矩阵分析其脉动衰减特性,得到往复泵频率和系统管路各参数对其衰减效果的影响规律;并以此为基础,结合所涉往复泵脉动频率,确定试验管路系统参数;通过试验验证的方式,探讨共振衰减理论是否适用于超低频往复泵设备。Accumulator is a commonly used equipment for reciprocating pump outlet flow pulsation at-tenuation .In this paper ,the mathematical model of accumulator and piping system is established .By using the distributed parameter method based on resonance attenuation theory ,the ripple attenuation characteristics are analyzed via transfer matrix ,and the influence law of the frequency of reciprocating pump and the parameters of piping system on the attenuation effect is given .On this basis ,in view of the pulsation frequency of the reciprocating pump ,the parameters of the testing piping system are de-termined ,and the applicability of resonance attenuation theory to ultra-low frequency reciprocating pump equipment is discussed through the method of experimental verification .
