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

Embodiment Construction

[0039] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. In the following descriptions and drawings, unless otherwise indicated, the same numerals in different drawings indicate the same or similar elements. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of arrangements consistent with aspects of the invention as recited in the appended claims. Each embodiment in this specification is described in a progressive manner.

[0040] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific ...

Abstract

The invention provides a high-performance multi-blade 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 opened at the center of the side wall of the rotor. In the ring groove, there are positioning slots with the same number as the shifting blocks evenly along the circumferential direction, and a blade is installed on each positioning slot. A cavity is formed between two adjacent blades, the surface of the ring groove and the inner wall of the housing. The blades are inserted into the chute, so that each cavity has a shifting block, and the shifting block divides the cavity into the first chamber and the second chamber. Two chambers; both ends of the rotor are connected with oil distribution blocks; the convex ring J1 on the outer wall of the housing 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, dial The block slides back and forth between the two blades, so that the volumes of the first chamber and the second chamber change periodically, and the changes of the two are just opposite.

Description

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