Vane pump principle of work: Single-role and double-acting vane pump What is the difference?

[Asia Pump Network News] There are many types of vane pumps, mainly divided into single-action vane pump and double-action vane pump two categories. Xiaobian now for everyone to analyze the working principle of these two types of vane pump to see what difference. Vane Pump A single-action vane pump principle Slides are embedded in the tank, you can slide freely, when the rotation occurs, the vane slipped under the centrifugal pump casing, vane pump is a positive displacement pump, phase Adjacent to the two vanes move to the bottom with the pump housing and the rotor closed the smallest volume, the maximum at the top, when the rotor rotates clockwise, the adjacent two vanes through the process from the bottom to the top 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). Second, double-acting vane pump working principle When the motor drives the rotor along the rotation, the vane in the centrifugal force and the bottom of the vane pressure oil under the dual role of the outstretched, the top close 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.
