摘要
通过对限压式变量泵在多级调速系统中压力和流量的分析,论证了在多级调速时速度下降负载压力上升时压力死区的存在。给出了限压式变量泵弹簧刚度对压力死区的影响。
Based on the variable pump pressure type in multistage speed regulation system of the pressure and flow analysis demonstrated in multi-stage speed, load pressure drop speed up when the pressure when death. Given the limited pressure of pump pressure die spring stiffness of influence.
