This pump uses O-ring sealing on the combination surface to solve oil leakage. The oil pressure balance composed of spherical oil distribution discs can improve stable operation and enhance the ability to resist pollution.

The goal of combining with IP pumps in addition to single pumps has been achieved, expanding its usage.

There are two types of straight axis inclined disc piston pumps: pressure oil supply type and self suction type. Pressure oil supply hydraulic pumps mostly use hydraulic oil tanks with air pressure. Hydraulic oil tanks that rely on air pressure for oil supply must wait for the hydraulic oil tank to reach the required air pressure before operating the machine after each start-up. If the machine is started when the pressure in the hydraulic oil tank is insufficient, it will cause the sliding shoes inside the hydraulic pump to pull off, resulting in abnormal wear of the return plate and pressure plate inside the pump body.

Due to the structural characteristics of radial pumps, fixed axial flow radial piston pumps are more impact resistant, have a longer lifespan, and have higher control accuracy than axial piston pumps. The variable stroke of the variable stroke short pump is achieved by changing the eccentricity of the stator under the action of the variable plunger and limit plunger, and the set eccentricity is 5-9mm (depending on the displacement size), resulting in a short variable stroke. And the variable mechanism is designed for high-pressure operation, controlled by a control valve. Therefore, the response speed of the pump is fast. The radial structure design overcomes the problem of eccentric wear of sliding shoes in axial piston pumps. Significantly improve its impact resistance.

This is an electromagnetic valve installed as a pressure compensation model to store energy when hydraulic pressure generated by a pump is not needed, in order to minimize the loss of energy. Only slight heat will be generated.

Obtain two supplementary pressure models based on the "ON" and "OFF" switches of the solenoid valve. When the actuator speed is constant, the force of two hydraulic systems can be controlled.

By using the sequence valve installed in the pump and the electromagnetic valve for energy transfer, the discharge volume can be divided into two sections, and energy can be transferred and stored when no pressure is needed.

Two types of pressure flow characteristics can be obtained through the solenoid valve and hydraulic cylinder installed in the pump.

High pressure achieves high efficiency and has the characteristic of a variable displacement pump that only obtains the necessary displacement, making a contribution to the energy saving of hydraulic devices.

Low noise is achieved through high rigidity supported by the semi cylindrical inclined plate method used in the PVS series, as well as the use of multi pillar plugs (previously 9 ¥ 11) and oil distribution plates.
