【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。
[Abstract]:Accumulator is a common equipment for attenuating flow pulsation at the outlet of reciprocating pump. In this paper, the mathematical models of accumulator and pipeline system are established, and the pulsation attenuation characteristics are analyzed by transfer matrix, which is commonly used in the theory of resonance attenuation. The influence of the frequency of reciprocating pump and the parameters of the system pipeline on the attenuation effect is obtained. Based on this, the parameters of the test pipeline system are determined by the pulsation frequency of the reciprocating pump. This paper discusses whether the theory of resonance attenuation is applicable to ultra-low frequency reciprocating pump equipment.
