Sliding pump, also known as skateboard pump and vane pump, it has a single role and double-acting two categories: First, the single-action vane pump rotor It is a radial groove cylindrical body, the slides placed within the slot, the rotor eccentrically Placed in the pump body, as long as the adjustment of the stator rotor eccentricity size, can change the pump flow; change the direction of eccentricity, you can change the direction of the pump output liquid, so this pump should be made adjustable vane pump or Variable vane pump. Second, double-acting vane pump rotor surface curve is a circle, rotor and stator center coincidence; the inner surface of the stator curve is similar to the oval, when the rotor rotates twice a week, there are two inhalation and discharge process. The relative position of the rotor and stator of such a pump is invariable, so it is also called non-adjustable vane pump or quantitative vane pump.
