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 discloses a high-performance variable multi-blade pump. The high-performance variable multi-blade pump comprises a shell, a rotor, blades and sliding shoes. The outer side of the rotor is covered with the shell. The shell is semi-spherical, a circular ring K1 extends inwards from the end surface of the shell, and the circular ring K1 passes the spherical center of the shell. The rotor is provided with at least three chutes which are evenly distributed in the circumferential direction. Blades are slidably arranged on the chutes, the outer end heads of the blades are arranged on the sliding shoes, and the sliding shoes are abutted against the side surface of the circular ring K1. A cavity is formed among every two adjacent blades, the rotor surface, the inner wall of the shelland the side wall of the circular ring K1. The axis of the rotor and the axis of the shell do not coincide. According to the high-performance variable multi-blade pump, the relative linear velocity ofthe blades and the shell is very small, the blades can operate at extremely high speed, the size is very small, the displacement is very large, and the output pressure is very high.

Description

technical field [0001] The invention relates to a multi-vane pump, in particular to a high-performance variable multi-vane 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...
