YLC Hydraulic Oil Pump Vane Pump VP1-12 Series VP1-15 VP1-20 VP2-30 VP2-40 VP1-15-15 VP1-20-20 VP2-30-30 VP2-40-40

VP1-15-70, VP1-20-35, variable vane pump The VP series variable vane pump is a pressure limiting variable vane pump with a pressure adjusting device and a flow adjusting device. The input flow of the pump can be automatically adjusted according to load changes, making its output power adapt to the working speed and load size of the load. It is characterized by high efficiency, energy saving, safety, and reliability. It is particularly suitable for power sources in pressure systems that use volumetric speed regulation, such as metal cutting machines, pressure machines, leather machines, and hydraulic stations.

The design integrates two or even three electromagnetic directional valves with a corresponding number of pilot relief valves, and each pilot relief valve can be independently set with a pressure value
When the control pressure of the pilot valve does not meet the minimum control pressure of the electro-hydraulic reversing valve, the spring is centered and the spring is reset
The time from the energization of the hydraulic electromagnetic iron to the termination of the valve core commutation becomes the commutation time. Short reversing time is beneficial for improving work efficiency, but it is relatively easy to cause hydraulic shock.
