[Pump News Asia] Slippage pump alone, may we still do not quite understand, Xiaobian now graphic mode, to explain the working principle of the vane pump, so that we can clearly understand the vane pump principle . Vane pump graphic analysis Sliding pump, also known as skateboard pump, vane pump, the structure diagram as shown above. It mainly by the rotor, stator (ie pump housing), skateboards and cover on both sides of the composition. Rotary pump (see pump) that transports liquid or pressurizes it by relying on changes in the working volume created between the pump cylinder and the adjacent two blades on the rotor when the eccentric rotor rotates. The rotor is a cylinder with a radial groove in which slides are mounted and the slides slide freely in the groove. Rotor eccentrically placed in the pump body, when the rotor driven by the prime mover rotation, the slider by centrifugal force or spring force on the inner wall of the pump body. Half turn in the rotor, the space surrounded by two adjacent leaves gradually increased to form a partial vacuum and inhalation of liquid. Then half a turn, this space is gradually reduced, squeeze the liquid, the liquid pressure to the discharge tube. According to the installation position of the vane has a built-in vane pump (vane mounted on the rotor) and the outer vane pump (vane mounted on the pump body). This type of pump working pressure below 7MPa. Vane pump structure is more compact, small size, flow more evenly, stable operation, pulsation and noise, efficiency than the average gear pump high. Vane pump structure is complex, easy to wear parts.
