Double acting multi-vane pump

Abstract

The invention discloses a double acting multi-vane pump. The double acting multi-vane pump comprises a shell body, a rotor, blades and a sliding boot, the rotor is covered with the shell body, and a round of ring K1 extends in the center of the inner wall of the shell body to the direction of center of a ball; a ring groove is formed in the center of the side wall of the rotor, at least three leftsliding grooves distributed evenly in the circumferential direction are formed in the left side surface of the ring groove, right sliding grooves with the same number of the left sliding grooves andcorresponding to the left sliding grooves one by one are formed in the right side surface of the ring groove, and the blades are slidably arranged on the left sliding grooves and the right sliding grooves; the ring K1 is clamped between the blades of the left sliding grooves and the right sliding grooves, the outer end heads of the blades are installed on the sliding boot, and the sliding boot isconnected with the side surface of the ring K1 in an abutting mode; the adjacent two blades, the surface of the ring groove, the inner wall of the shell body and the side wall of the ring K1 form an accommodating cavity; and the axial of the rotor and the axial of the shell body do not coincide. According to the double acting multi-vane pump, the relative linear speed between the blades and the shell body is very small, running at a very high speed can be achieved, the volume 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 double-acting 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 pump cannot...
