The hydraulic station is a combination of a pump unit, an integrated block or valve combination, an oil tank, an electrical box, and an accumulator.

? Pump unit: equipped with a motor and oil pump; it is the power source of hydraulic station to convert mechanical energy into pressure energy of hydraulic oil.

? Integrated block: consists of  hydraulic valves and channels, for . direction, pressure and flow adjustments of the hydraulic oil. 

? Valve combination: Plate valves are mounted on the vertical board to connect with the tubing behind the board, with the same function as the integrated block.

? Oil tank: A semi-closed sheet-welded container equipped with an oil strainer, air filter, etc., for oil storage, cooling and filtration.

? Valve combination: Plate valves are mounted on the vertical board to connect with the tubing behind the board, with the same function as the integrated block.

? Accumulator: A device for storing energy.

The working principle of the hydraulic station: the motor drives the oil pump to rotate and supply oil from the tank , converting the mechanical energy into the pressure energy of the hydraulic station. The hydraulic oil , subject to the direction, pressure and flow adjustment in the integrated block (or valve combination), is led to the cylinder or oil motor of the hydraulic machine through an external pipeline to enable various hydraulic machines to work while  controlling its switching of direction , magnitude of the force,  and the value of speed.
