Single action: the slide is embedded in the groove and can slide freely. When the rotation is generated, the slide is sucked onto the pump casing by centrifugation. It is a positive displacement pump. When the two adjacent slides move to the lower side, the pump The closed volume of the shell and the rotor is small, and the Zui is large at the top. When the rotor rotates clockwise, the process of the adjacent two slides from the lower side of the Zui to the upper side of the Zui is the volume increasing process, so the oil absorption (from the fourth quadrant to The second quadrant); from Zui to Zui is the volume reduction process, so the oil is pressed (from the second to the fourth quadrant).
Double acting: When the motor drives the rotor to rotate, the sliding piece protrudes outward under the double action of the centrifugal force and the pressure oil at the bottom of the sliding piece, and the top thereof is closely attached to the inner surface of the stator. The four sliding vanes on the four-section concentric arc form four sealed working oil chambers with the outer surface of the rotor, the inner surface of the stator and the two distribution plates. These oil chambers change from small to large or large to small as the rotor rotates, and can be connected through the oil suction window of the distribution plate (connected to the suction port) or the oil discharge window (connected to the oil discharge port). Inhale or pressurize the oil.
In the process of each revolution of the rotor, each working oil chamber completes two oil suction and oil pressure, so it is called double-acting sliding vane pump. Because the high and low pressure chambers are symmetric with each other, the shaft is balanced by force and is unloading. Slide pump
The sliding vane pump is equipped with small power and large flow. It is a good choice for gas stations, oil depots, chemical plants, oil refineries, aviation kerosene and steam refueling.
