Embodiment

[0016] Embodiment: a kind of vane pump such as figure 1 , figure 2 As shown, the pump body 1 is included, the pump body 1 is provided with a hollow stator 2, the inner cavity of the stator 2 is oval, the rotor 5 is arranged in the inner cavity of the stator 2, the rotor 5 is rotatable relative to the stator 2, and the rotor 5 It is cylindrical, and there are twelve blade grooves evenly distributed on the outer peripheral surface of the rotor 5. The plane where the blade grooves are located passes through the axial centerline of the rotor 5. There are blades 6 with clearance fit in the blade grooves, and the blades 6 are in the blade grooves. Can move freely along the radial direction of the rotor 5, such as figure 1 , image 3 As shown, the blades 6 respectively extend out of the two end faces of the rotor 5, and the left oil pan 7 is arranged outside the left end face of the rotor 5, and the right oil pan 3 is arranged outside the right end face of the rotor 5, and the lef...

Abstract

The invention discloses a vane pump. The vane pump comprises a rotor and a hollow stator, wherein an inner cavity of the stator is in an oval shape, the rotor is arranged in the inner cavity of the stator, the rotor can rotate relative to the stator, a plurality of vanes are circumferentially and uniformly distributed at the peripheral face of the rotor and can move back and forth relative to the rotor along the radial direction of the rotor, and oil discs are respectively arranged outside two end faces of the rotor; and the stretching parts respectively stretch to two end faces of rotor from the vanes, cams are arranged on the side faces of one sides, facing the rotor, of the oil discs, the peripheral faces, facing the rotor, of the cams are abutted with one side faces, facing the rotating center of the rotor, of the stretching parts of the vanes, and the directions of bulges on the peripheral faces, abutted with the vanes, of the cams are accordant with the direction of a long shaft of the oral inner cavity of the stator. The vane pump has the beneficial effects that the problem that the centrifugal force of the vane pump or a low-pressure low-speed vane pump is insufficient during startup because the viscidity of hydraulic oil is high in winter is solved, and the hydraulic oil is guaranteed to be effectively pumped out by the vane pump.

Description

technical field [0001] The present invention relates to a hydraulic pump, and more particularly, the present invention relates to a cartridge vane pump. Background technique [0002] The working principle of the vane pump: the motor drives the rotor to rotate through the transmission shaft, and the vanes on the rotor slide outward in the vane grooves under the action of centrifugal force, so that the outer ends of the vanes are pressed against the inner surface of the stator to act as a seal. Separate the oil suction chamber from the oil discharge chamber. As the rotor continues to rotate, when the vane moves from the small arc area to the large arc area on the inner surface of the stator, the volume between the two sealing vanes increases, and it passes through the side The oil suction port on the plate absorbs oil; when the vane moves from the large arc area to the small arc area on the inner surface of the stator, the volume between the two sealing vanes becomes smaller, ...
