A slag removal base for vane pump

Abstract

The invention relates to the technical field of deslagging for a vane pump, in particular to a deslagging base used for the vane pump. The deslagging base comprises a pump case and a base body which is fixed on the lower end of the pump case, wherein an oil pumping cavity is arranged in the pump case; an oil outlet pipe is arranged on the left side of the pump case; and an oil pumping pipe is arranged on the right side of the pump case. According to the deslagging base used for the vane pump, a drawer-type slag accumulation box is arranged in the base body, so that slags in the pump body can be removed without detaching the whole vane pump; operation difficulty is greatly lowered; an extrusion groove and a slag emitting groove which communicate with the slag accumulation box are separately formed in the bottom end of a stator and the bottom end of the pump case, and the slags are prevented from returning into the pump body by utilizing a extrusion filter net, so that safety of the vane pump is greatly improved; slag accumulation is prevented; and the service life of the vane pump is prolonged.

Description

technical field [0001] The invention relates to the technical field of slag removal for vane pumps, in particular to a slag removal base for vane pumps. Background technique [0002] The vane pump is a pump in which the vanes in the rotor groove are in contact with the pump casing (stator ring), and the sucked liquid is pressed from the oil inlet side to the oil discharge side. In the existing vane pump, under the action of centrifugal force and pressure, the vane rotates to generate centrifugal force, thereby sealing with the inner surface of the pump casing (stator ring), thereby forming a working volume with the inner wall of the stator, but when the vane rotates at a high speed for a long time In the process, a small amount of metal slag will be generated inside due to friction. If it cannot be discharged through the oil pumping process, the internal accumulation will easily lead to deformation of the internal chamber, resulting in increased wear of the blades, and even ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, an improved slag removal base for the vane pump is provided to solve the problem that the traditional vane pump does not have an automatic slag removal device, which causes debris to accumulate inside. It is easy to cause deformation of the internal chamber, leading to increased wear of the vane, and even damage to the entire vane pump. However, the internal slag removal of the traditional vane pump requires the removal of the entire pump body, which is a very troublesome problem.
