摘要
多变载液压系统可适应负载变化工况的需求。利用串联方式组装齿轮泵-柱塞泵双液压泵,将单齿轮泵高压力输出模式调整为双泵分级模式来控制泵运行,同时满足高低压负载的不同使用工况要求。通过在模型仿真过程中调整泵出口流量和压力变化展开仿真分析,研究结果表明,采用增大电机转速方法能够有效调节流量脉动的变化范围。逐渐提高负载后,流量脉动区间出现减小。单输出功率结果表明,可以通过串联泵系统来实现功率叠加,从而利用低功率电机完成大功率输出过程。
Multi-variable load hydraulic system can be adapted to the needs of load changing working conditions.The gear pump-plunger pump dual hydraulic pump is assembled in series,and the high pressure output mode of the single gear pump is adjusted to the dual-pump grading mode to control the pump operation,which can meet the requirements of different working conditions of high and low pressure loads at the same time.By adjusting the pump outlet flow and pressure changes in the model simulation process to carry out simulation analysis,the results show that the method of increasing the motor speed can effectively adjust the flow pulsation range.After gradually increasing the load,the flow pulsation range appears to decrease.The single output power results show that the power can be superimposed by series pump system,so as to complete the high-power output process using low-power motors.
