摘　　要：文章介绍了一种双作用变量叶片泵自动控制系统 ,通过电脑控制变频器 ,改变叶片泵转速 ,达到粗调目的 ;电脑控制电液数字阀 ,起微调作用。蓄能器的利用 。A auto-control system of double acting variable displacement vane pump is introduced in the paper. By controlling the transducer, the computer can change the rotate speed of vane pump and achieve the coarse adjustment. The computer also can achieve the vernier adjustment by controlling the electro-hydraulic digital valve. The use of accumulator makes further improvement on the system's stability.
