Variable displacement pump's control style has many ways, such as constant pressure, constant fluid, constant power, electrohydraulic proportional and load-sensing etc.

变量泵的控制方式有恒压力、恒流量、恒功率、电液比例和负荷敏感控制等。

Depending on the fluid volume and precharge pressure of the accumulator, a limited amount of hydraulic energy is then available independent of any other power source.

根据储能器的流体体积和预充气压力，可获得某限定数量的液压能量而不依赖任何其它动力源。
