Problems solved by technology

This type of vane pump is sealed by a contact line between the vane and the cylinder body, so the sealing performance is poor, the output pressure is low, and the relative linear velocity between the vane and the cylinder body is very high during rotation, resulting in great friction. As a result, the overall wear of the vane pump is fast, the life is short, and the efficiency is low

Abstract

The invention provides a high-performance vane hydraulic pump, which includes a casing, a rotor, blades, an oil distribution block and a guide block. A chute is formed between the two shifting blocks, and a ring groove is formed on the side wall of the rotor. In the ring groove, the same number of positioning grooves as the shifting blocks are evenly opened along the circumferential direction. A blade is installed on each positioning groove, and the blade is inserted into the sliding In the groove, there is a shifting block in each cavity, and a cavity is formed between two adjacent blades, the surface of the ring groove, the shifting block and the inner wall of the housing; one end of the rotor is connected with an oil distribution block; The convex ring J1 on the outer wall is placed in the guide groove of the guide block; the axis of the rotor and the axis of the housing do not coincide; when the rotor rotates, the shift block slides back and forth between the two blades, so that the volume of the cavity changes Periodic changes.

Description

technical field [0001] The invention relates to a multi-vane pump, in particular to a high-performance vane hydraulic pump. Background technique [0002] The existing vane pump structure is that the rotor is placed eccentrically in the oil cylinder, and the blades are placed in the rotor radially or at a certain angle with the rotor radius. When the rotor rotates at a high speed during operation, the blades are thrown out under the action of centrifugal force and formed with the oil cylinder. Sealed cavity, the volume change generates pressure when rotating. . This type of vane pump is sealed by a contact line between the vane and the cylinder body, so the sealing performance is poor, the output pressure is low, and the relative linear velocity between the vane and the cylinder body is very high during rotation, resulting in great friction. As a result, the overall wear of the vane pump is fast, the life is short, and the efficiency is low. In this way, the speed of the p...
