The power unit is used as an oil supply device, which is connected with several hydraulic cylinders through an external pipeline system to control the actions of multiple groups of valves.
The oil tank, oil pump and accumulator form an independent and closed power oil source system. The oil station can be equipped with a PLC control system, which controls the internal hydraulic functions of all power units and generates signals to exchange with the control room.
The hydraulic control valve is directly installed on the hydraulic cylinder, and the high-pressure oil is pressed into the cylinder through this valve, or the high-pressure oil is discharged from it. Under normal conditions, the oil pump supplies oil to the system, automatically maintains the rated pressure of the power unit system, and realizes the function of maintaining the valve in any position by locking the control valve.
