Problems solved by technology
[0003] The above method can complete the basic pressurization function of the vane pump. However, the reciprocating motion of the vane in the vane groove and the rotation with the rotor make it impossible to form an effective lubricating oil film between the vane, the cover plate and the chassis, so that the vane There is no effective lubrication between the upper and lower end faces, the cover plate and the chassis, so it is easy to wear and damage
[0004] It is necessary to provide a new type of vane pump to solve the problem that the upper and lower end faces of the vane, the cover plate and the chassis cannot be effectively lubricated

Embodiment Construction
[0016] In different drawings, the same or similar parts are indicated by the same reference numerals.
[0017] It should be understood that the drawings are only used to illustrate the present invention, and the dimensions, proportions and numbers of the components are not intended to limit the present invention.
[0018] see figure 1 As shown, the vane pump 100 of the present invention includes a stator 1, the stator 1 has a receiving groove 11, the receiving groove 11 is cylindrical, a cover plate 5 is arranged on the upper side of the stator 1, and a cover plate 5 is arranged on the lower side of the stator 1. There are chassis 4. The above-mentioned cover plate 5 , stator 1 and chassis 4 can be combined and fixed, so that the accommodating groove 11 is partially closed. The rotor 2 is arranged eccentrically with the stator 1 in the receiving groove 11 . A plurality of vane slots 21 are radially formed in the rotor 2 , and a vane 22 is arranged in each vane slot 21 . Th...

The invention relates to a vane pump, comprising a stator, the stator has a receiving groove, and a chassis and a cover plate are correspondingly provided on the upper and lower sides of the receiving groove, so that the receiving groove forms a receiving space, and the receiving groove A rotor is arranged inside, a plurality of vane slots radially formed in the rotor and a plurality of vanes that can reciprocate slide in the vane slots, wherein the lower end surfaces of the vanes are in contact with the chassis, and the vanes The upper end surface of the upper end surface is in contact with the cover plate, and the upper end surface and / or the lower end surface are chamfered. Due to the setting of the chamfer, better lubrication can be achieved between the vane of the vane pump, the cover plate and the chassis.
Description
technical field [0001] This application relates to a vane pump and its vanes, in particular to a vane pump and its vanes with better lubricating effect. Background technique [0002] The vane pump is a kind of pump widely used in the industrial field. Generally, vane pumps comprise a stator with a void space in which a rotor is arranged eccentrically to the stator. There are a plurality of vane slots extending radially along the rotor inside the rotor, and vanes are arranged in the vane slots. The vane can reciprocate in the vane slot along the radial direction of the vane slot. The upper and lower sides of the stator and the rotor are provided with a cover plate and a chassis to seal the above-mentioned vacant space. The upper end surface of the vane is in contact with the cover plate and forms a seal, while the lower end surface of the vane is in contact with the chassis to form a seal. Through the reciprocating movement of the vane in the vane groove, the fluid sealed...
