Abstract
The invention relates to a high-speed dual-inclined-plate axial-plunger switch reluctance synchronization motor pump for an airplane. The motor pump comprises a motor stator connected to a motor housing. A gap is formed between the motor stator and a motor rotor. The motor rotor is supported on a distributor shaft by a bearing; and two ends of the distributor shaft are supported on a left motor end cover and a right motor end cover. Inclined plates are connected to the inner sides of the left motor end cover and the right motor end cover; return plates compress piston shoes on the inclined plates; and one end of each return spring is installed on the motor rotor and the other end compresses a return support block on one return plate. One end of each plunger is installed on one piston shoe and the other end is installed on the motor rotor and can moves along the axis direction of the plunger inside the motor rotor. A cylinder body of a pump and a motor rotor are combined, thereby reducing the overall dimension effectively and reducing the rotational inertia. Because the distributor shaft does not rotate with the motor rotor, the rotating speed is improved; and the distributor shaft is used for distribution, so that the distribution one-way valve is saved and thus the processing difficulty of the distributor shaft is reduced.
Description
Technical field
The invention belongs to electric-motor pump technical field, be specifically related to a kind of aircraft high speed two inclined plate axial piston switching magnetic-resistance synchronous electric pump.
Background technology
The electric-motor pump that existing market is boarded a plane have employed the mode that common electric machine is combined with plunger displacement pump, the cylinder body of pump is arranged on rotor, one end of plunger is installed in cylinder body, and the other end of plunger is withstood on swash plate by piston shoes, and can slide on swash plate.Cylinder body is provided with unidirectional valve and the pintle of flow, pintle one end has circumferential hole, can carry out flow communication with the external world.In the course of work, rotor drives hydraulic pump cylinder body to rotate, and the plunger being arranged on cylinder interior along with rotation, and in rotary course, axial displacement can occur, and produces the change of volume while axial displacement.Under the synergy of flow unidirectional valve, fluid enters plunger cavity volume through pintle or extrudes cavity volume, completes assignment process.The periphery perforate of pintle high-pressure side, is in communication with the outside, and realizes pump oil process.This kind of electric-motor pump is the combination of common electric machine and plunger displacement pump, and speed governing difficulty is large, and processing and manufacturing is complicated.The rotor of motor separates with pump cylinder, and the overall dimensions caused is bigger than normal, installs difficulty.Pintle and pump cylinder rotate simultaneously, and moment of inertia is large, sluggish.
