The inner surface of the stator of the variable vane pump is a circular shape with an eccentricity between the rotor and the stator. Only one oil suction window and one oil pressure window are opened on the oil distribution plate. When the rotor rotates in the direction of the arrow as shown by the motor, when the blade passes through the lower half of the stator, it protrudes from the blade groove under the action of centrifugal force, and the sealing volume between the two blades increases to achieve oil absorption; the blade passes through the stator In the upper part, the inner surface of the stator is gradually pressed into the groove of the vane, and the sealing volume is reduced to achieve oil pressure. The rotor of the pump rotates once per revolution, and each sealed volume absorbs and presses oil once. Changing the amount of eccentricity between the stator and the rotor changes the displacement of the pump, so it is called a variable hydraulic vane pump.
1. Hydraulic VP Vane Pump can have automatic high-speed flow and compensation function under pressure setting. It has less power loss and lower heat generation than quantitative vane pump. It is a high-efficiency vane pump that saves energy and is the best for system design engineers in high efficiency loops. select.
2. The operation is balanced and quiet, especially suitable for machine tools and indoor requirements.
3. Contains pressure adjustment mechanism, the system can not use pressure regulating valve and is suitable for direct motor, easy to assemble.
4. There are a variety of different pressure and flow ranges available for any choice.
