摘　　要：基于给定的不同轴向间隙,利用Pumplinx数值分析软件,对摆线转子泵的内部流场进行三维非定常数值模拟研究,获得轴向间隙对摆线转子泵性能的影响规律。仿真结果表明:在转速不变的条件下,随着轴向间隙的增加,摆线转子泵的容积效率明显下降,但流量脉动幅度没有明显变化;在轴向间隙不变的条件下,随着转速的增加,摆线转子泵容积效率变大。Based on the given different axial clearances,the three-dimensional unsteady numerical simulation of the internal flow field of the gerotor pump is carried out by using the numerical analysis software Pumplinx to obtain the influence law of the axial clearance on the performance of gerotor pump.The simulation results show that under the condition of constant speed and with the increase of axial clearance,the volumetric efficiency of gerotor pump decreases drastically,the amplitude of flow pulsation,however,keeps nearly unchanged.Under the condition of constant axial clearance and with the increase of rotational speed,the volumetric efficiency of gerotor pump increases.
