A electric hydraulic power unit, also known as a hydraulic pump station, is an independent hydraulic unit. It supplies oil according to step-by-step requirements. And control the direction of hydraulic oil flow, pressure and flow, applicable to the host and the hydraulic device can be separated from a variety of hydraulic machinery. Users after the purchase as long as the hydraulic power unit and the host of the actuator (oil cylinder or oil motor) connected to the oil pipe, hydraulic machinery can achieve a variety of prescribed actions and work cycle.
The electric hydraulic power unit is a combination of pump unit, integrated block or valve combination, tank, electrical box. The function of each component is:
Pump unit – equipped with electric motors and oil pumps, is the power source of the electric hydraulic power unit, the mechanical energy into the hydraulic oil pressure energy.
Integration block – assembled by the hydraulic valve and channel body. The hydraulic oil to implement the direction, pressure and flow regulation.
Valve combination – plate valve mounted on the vertical plate, the plate after the tube connection, with the same function as the integrated block.
Oil tank – plate welded semi-closed container, also equipped with oil filter, air filter, etc., for oil storage, oil cooling and filtration.
Electrical box – there are two types. A set of external lead terminal board; a configuration of a full set of control appliances.
The working principle of the hydraulic power unit operates as follows: initially, the motor drives the oil pump to rotate. Consequently, the pump draws oil from the oil tank to supply it to the system. This process converts mechanical energy into the pressure energy of the hydraulic power unit.
Subsequently, the hydraulic oil flows through the integrated block or valve combination. This arrangement allows for adjustments in direction, pressure, and flow rate. Through the external pipeline, the hydraulic oil reaches the hydraulic machinery cylinders or oil motors.
As a result, the hydraulic power unit can control changes in direction, force magnitude, and speed. This capability enables various types of hydraulic machinery to perform their intended tasks effectively.
