| Abstract: | The hydraulic drill system based on the sensitive load was studied. This hydraulic system uses the electric motor power at the maximum, its speed control of the power head has nothing to do with the load, the speed can adjust in the adjustment scope according to the technological requirement. The system can discharge by the LS, it has high security and can avoid the overflow. Due to the application of the control technology of constant power, cutting by pressure, sensitive to load and proportional directional valve, the efficiency and security of the hydraulic system of drill was improved. |
