【摘要】 为了对某阀配流式柱塞泵的特性进行研究,该文利用AMESim软件建立了该柱塞泵的液压系统模型,对其出口压力与流量特性,柱塞腔压力特性,吸入阀、排出阀运动规律等进行了分析。仿真结果表明:压力与流量特性与泵的实际设计参数基本一致;吸入阀、排出阀的启闭存在滞后现象;进口管道采用橡胶软管有利于减小阀芯对阀座的撞击,有利于减小压力脉动。更多还原

【Abstract】 The characteristic f a piston pump with flat valves was analyzed. Its model was established in AMESim and the performance of pressure and flow, the cavity pressure changing, the kinematics of opening and closing of inlet valve and outlet valve, the influence factor of vibration were studied by simulation. The simulation results show that the results are consistent with the design parameters of the pump and opening lags behind closing between inlet valve and outlet valve. In addition, the inlet pipe with rubber hose is beneficial to reduce not only the impact that spool beat on valve-seat, but also the pressure pulsation.更多还原
