Variable stator vane pump surface is a circular room, the rotor and stator eccentricity have variable pump. Maintenance, the oil pan is only open a window and a suction pressure of the oil window. When the rotor rotates in the direction of the arrow in the motor-driven variable displacement pump. Maintenance of telephone, the lower half of the blade through the variable pump stator, under the action of centrifugal force, extending from the blade groove, sealed volume between the two blades is increased, to achieve suction; leaf blade via the upper half of the stator, the stator inner surface was gradually pressed into the vane groove, sealed volume reduction, to achieve oil pressure. Pump rotor every turn, each sealed volume suction, pressure oil each time. Changing the amount of eccentricity between the stator and rotor, you can change the variable displacement pump pump. Training, so called variable vane pump [2]. 1. Edit variable vane pump characteristics can have automatic high-speed traffic and compensation under the pressure setting, less than quantitative vane pump power consumption, low heat, is a high-efficiency energy saving vane pump for system design engineers in high efficiency The circuit best choice. 2. The balance of quiet operation, especially for machine tools and indoor requirements. 3. containing pressure adjustment mechanism, the system can not apply direct pressure regulator and motor assembly easy. 4. A wide range of different pressures and flow range, for arbitrary choice. Variable pump. Variable pump maintenance _ _ Jinan crystal by crystal Chong Chong hydraulic hydraulic machinery Limited.
