ã€Vane pump works】 Single role: the vane is mounted in the groove, you can slide freely, when the rotation is generated, the vane sloshing under centrifugal pump casing, vane pump is a positive displacement pump, adjacent Of the two vanes moved to the bottom and the pump housing and the rotor closed the smallest volume, the maximum on the top, when the rotor rotates clockwise, the adjacent two vane experience from the bottom to the top of the process is the volume increase process , So oil (from the fourth quadrant to the second quadrant); from top to bottom is the volume reduction process, so press the oil (from the second to the fourth quadrant). Double action: When the motor drives the rotor to rotate, the vane protrudes outwards under the double action of centrifugal force and pressure oil at the bottom of the vane, and the top of the vane sticks to the inner surface of the stator. The four vanes on the four concentric circular arcs respectively form four sealed working oil chambers with the outer surface of the rotor, the inner surface of the stator and the two valve plates. These oil chamber with the rotation of the rotor, seal the working oil chamber produce small to big or small to small changes, can be through the oil distribution window suction port (connected to the suction port) or drain window (connected to the drain port) Inhale or extrude the oil. In the rotor per revolution, each working oil chamber to complete two oil and oil pressure, so called double-acting vane pump, due to symmetrical symmetry between high and low pressure chamber, the shaft force balance, unloading type. Vane pumps equipped with small power, large flow, gas stations, oil depots, chemicals, refineries, aviation kerosene, the best choice for refueling ships.
