摘要
变量柱塞泵的控制方式丰富多样,可分为压力控制、流量控制和功率控制等。其中压力控制是变量柱塞泵最常用的变量控制方式,又称恒压控制。变量泵内部设定输出压力值,液压泵和系统将维持设定值工作。通常,泵内的恒压工作状态控制的关键参数为泵出口压力和响应时间,并且各参数之间相互关联、相互影响。基于恒压变量泵的工作机理,分析各项性能指标对其影响,并通过AMEsim仿真和实际试验相结合的方式,最后验证理论和仿真结果基本一致,为今后的相关研究具有指导意义。
The control methods of variable piston pump are various,including pressure control,flow control and power control.Among them,pressure control is the most commonly used variable control mode of variable piston pump,also known as constant pressure control.The output pressure value is set inside the variable displacement pump,and the hydraulic pump and system will maintain the set value.Usually,the key parameters of constant pressure working state control in pump are pump outlet pressure and response time,and the parameters are interrelated and influence each other.Based on the working mechanism of the constant pressure variable displacement pump,the influence of various performance indicators on it was analyzed.Through the combination of AMESim simulation and actual test,the theoretical and simulation results are basically consistent,which has guiding significance for the future related research.
