Second, the operating characteristics of a hydraulic drive, the size of the hydraulic transmission fluid pressure depends on the load. That pressure only varies with changes in load-being of the hydraulic system maintenance, nothing to do with traffic. 2, the size of the movement depends on the speed of the actuator input flow regardless of pressure. 2, the actuator element whose role is to perform the hydraulic energy into mechanical energy Yan'an hydraulic system maintenance, output to the work of agencies acting. The actuator comprises a hydraulic cylinder and a hydraulic motor hydraulic system maintenance, the hydraulic cylinder is a linear motion of the motive fluid, which output force and velocity; hydraulic motor is to achieve a rotational movement of the motive fluid, which output torque and speed. 3, the control element control element is a hydraulic system in a variety of control valves. Including: changing the flow direction of the directional control valve, regulating the movement speed of the pressure control valve and flow control valve regulating the pressure of three categories.
