The locating cover plate comprises a locating inner end face, a locating outer end face and a locating side face. The rectifying sleeve comprises a rectifying inner wall face, a rectifying outer wall face, a throttle wall face and a flow stop wall face. The mounting cover plate comprises a mounting inner end face, a mounting outer end face and a mounting side face. A rectifying outer side clearance containing cavity is formed by the rectifying outer wall face, an upper variable valve seat and a lower variable valve seat, a rectifying inner side clearance containing cavity is formed by the rectifying inner wall face and a cylinder body, and periphery fluid of the cylinder body is isolated. A throttle clearance containing cavity is formed by a throttle inner wall and the cylinder body, an outer side containing cavity of a left-end bearing communicates with the throttle clearance containing cavity, and bearing lubricating is facilitated. The device is simple in structure and convenient to maintain; an oil flowing area is effectively structured; the stirring losses of the axial plunger pump are reduced; the working efficiency is improved; the lubricating heat radiation performance is good; and the rectifying device is especially suitable for the high-speed axial plunger pump.

Description

technical field [0001] The invention relates to a rectifying device for reducing the stirring loss of an axial plunger pump, and is especially suitable for the axial plunger pump working under high-speed working conditions. Background technique [0002] The axial piston pump is the core component of the hydraulic transmission system, and its efficiency is crucial to the energy efficiency of the fluid transmission system. The energy consumption of the axial piston pump can generally be divided into three categories: volume loss, mechanical loss and stirring loss. Among them, the stirring loss is due to the fact that the rotating components of the axial piston pump work in the shell filled with oil, due to the viscosity of the fluid Power loss due to friction, turbulent friction and flow resistance. With the development of hydraulic pumps in the direction of high speed, for example, the speed of axial piston pumps in aerospace hydraulic systems reaches tens of thousands of re...
