nature : pump known as skateboards and vane pump, the structure shown in the schematic figure. It mainly by the rotor, stator (Body), the vane and cover both sides formed. Rotor is the cylinder radial groove, planters placed vane, the vane in bed free sliding. To eccentric rotor pump placed in the body, when the former motivated rotor rotates, centrifugal force on vane or springs in the body of the press tightly against the walls. The first half of the rotor turn, leaves two neighboring space surrounded by gradually increasing partial vacuum suction people liquid. Then a half turn, this space has gradually decreased, squeezing liquid, liquid pressure to discharge tube. According to the vane is located at the contents vane pump (vane mounted on the rotor) and installed vane pump (vane mounted on the pump body). Normally such work pressure in the pump reached 7MPa below. Vane pump more compact structure, and its dimensions are little more even flow, a smooth operation, and noise pulse of small, efficient than general high gear pump. Vane pump complex structures, and easy to wear parts. It is mainly used in machine tools, hydraulic machine, lifting transport machinery, engineering machinery and plastic injection molding machine hydraulic system and lubrication system.
