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-pressure and large-flow multi-vane pump, which includes a casing, a rotor, and blades. The casing is covered outside the rotor. At least three first positioning slots are evenly opened on the inner wall along the circumferential direction, and second positioning slots with the same number as the first positioning slots are uniformly opened on the ring K1 along the circumferential direction, and the blades are installed in the first positioning slot and the second positioning slot at the same time. On the groove; the second positioning groove divides the ring K1 into several partitions, a ring groove is opened in the center of the rotor side wall, and a left chute corresponding to the first positioning groove is opened on the left side of the ring groove. There is a right chute corresponding to the first positioning groove on the right side of the groove, the left side of the blade is slid on the left chute; the right side of the blade is slid on the right chute; two adjacent blades, A cavity is formed between the surface of the ring groove and the inner wall of the housing, and each cavity is provided with a partition plate, which divides the cavity into a left cavity and a right cavity.

Description

technical field [0001] The invention relates to a multi-vane pump, in particular to a high-pressure and large-flow 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 ...
