Abstract

The invention discloses a high-performance variable vane pump, which includes a housing, a rotor and blades. The housing covers outside the rotor, the housing is hemispherical, the end face of the housing extends inwards to be provided with a circle of circular rings K1, the circular rings K1 pass through the sphere center of the housing; positioning grooves are provided with the blades, the rotoris provided with sliding grooves corresponding to the positioning grooves one to one, and the blades on the positioning grooves are further slidably arranged on the sliding grooves and sealed throughsealing parts; the outer end tips of the blades are installed on sliding shoes, the sliding shoes abut against the side faces of the circular rings K1, an accommodating cavity is formed among every two adjacent blades, the surface of a ring groove, the inner wall of the housing and the side walls of the circular rings K1, the rotor is provided with oil ports with the same number as the accommodating cavities, each oil port communicates with the corresponding accommodating cavity, and both ends of the rotor are connected with oil distribution blocks correspondingly; and the outer wall of the housing is provided with a convex circular ring J1, the convex circular ring J1 is placed in a guide groove of a guide block, and the axis of the rotor do not coincide with that of the housing. According to the high-performance variable vane pump, the relative linear velocity between the blades and the housing is zero, and running at the extremely high speed can be achieved.

Description

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