| Abstract: | The pump-controlled variable frequency speed control s ystem changes the motor speed by changing the input frequency,thus changing the constant pump displacement and achieving the speed adjustment of the hydraulic cylinder.Compared to conventional valve controlled system,the system features no throttling losses,high efficiency,simple structure and high precision,and is suitable for large inertia hydraulic lifting machinery with high precision.T he paper builds a DSP-based pump-controlled hydraulic cylinder ... |
