摘要
结合某型号低温液氮泵的实际应用,建立了低温液氮泵的瞬时流量模型,给出了流量脉动率的计算公式,并仿真计算了不同参数条件下的瞬时流量及流量脉动率。导出了低温液氮泵的瞬时流量与泵出口压力之间的关系,给出了两者之间的传递函数。
An instantaneous flow model of cryogenic liquid nitrogen pump was established,a calculation formula of flow pulsation rate was provided,and the instantaneous flow and flow pulsation rate under different conditions were calculated to meet the practical application of a cryogenic liquid nitrogen pump.The relationship between the instantaneous flow and pump outlet pressure was derived for cryogenic liquid nitrogen pump and the transfer function was provided.
