Hydraulic power unit is a very common part of the hydraulic converter, is playing a very important role. The director is actually a gear mechanism, the role of the existence is to do rotation and steering, making the mechanical work more rapid and flexible.
Hydraulic power unit in the hydraulic power unit is an important part of the steering system, its role is also very large, can increase the steering and change the direction of the mechanical force in the process of operation, so that can achieve the direction and force required in the work. This kind of hydraulic power unit parts are also widely used in other fields, such as agriculture, shipbuilding, gardening, engineering and other machinery.
The hydraulic power unit is designed to be optimized for a variety of applications, such as truck operation in harsh environments, heavy lifting for extended periods of time, and other applications that require high performance and quality products. Used as an oil supply device, it is connected to several hydraulic cylinders through an external piping system to control multiple sets of valves.
In the hydraulic power unit, the oil tank, oil pump and accumulator form an independent closed power oil source system. The tank can be equipped with a PLC control system that controls all internal hydraulic functions and generates signals to exchange with the control room. Control elements such as hydraulic servo valve are directly mounted on the hydraulic cylinder, through which the high-pressure oil is fed into the cylinder or discharged from it.
Under normal conditions, the oil pump supplies oil to the system, automatically maintains the rated pressure of the system, and realizes the function of the valve in any position through the locking of the control valve. In the working state, the hydraulic actuator is controlled by the solenoid valve, the system command signal makes the solenoid valve move, control the oil pressure and the energy release of the accumulator, and then control the oil cylinder slide valve, drive the valve through the mechanical transmission mechanism, and implement the quick closing, normal opening and closing and test control.
The high pressure cylinder can be fixed on the valve stem or directly used as an actuator. The excess hydraulic oil is returned to the hydraulic station so that the piping system can control several parallel valves with one inlet pipe and one return pipe. This hydraulic station with special drive technology is used to control the actuators of the main steam valve and the turbine bypass system.
