Abstract

The invention discloses a vibration active control type axial plunger pump with a magnetic bearing, which comprises a casing, a stepped drive shaft, a swash plate, a plunger movement assembly, a cylinder body, a magnetically controlled outer ring of a radial cylinder body, a first 1, 2 Radial permanent magnetic bearings, axial positioning magnetic control bearings. The magnetically controlled outer ring of the radial cylinder body collects vibration signals in real time through a displacement sensor, and adjusts the magnetically controlled outer ring of the radial cylinder body according to the magnitude of the vibration. The first and second radial permanent magnetic bearings realize the levitation state of the stepped drive shaft through the principle of magnetic repulsion. The axial positioning magnetic control bearing regulates the electromagnetic force by controlling the magnitude of the current to ensure the axial positioning of the drive shaft. The invention proposes an active vibration control type axial piston pump with magnetic bearing and its control method, while realizing the suspension of the drive shaft, it can monitor and control the vibration of the cylinder body in real time, and reduce the vibration of the bearing and the drive shaft. The friction between them improves the dynamic stability of the cylinder block and improves the stability and reliability of the axial piston pump.

Description

technical field [0001] The invention belongs to the technical field of axial plunger pumps, in particular to an active vibration control axial plunger pump with magnetic bearings. Background technique [0002] Axial piston pumps have the advantages of small size, large power-to-weight ratio, and various variable modes, and have been widely used in construction machinery, ocean engineering, aerospace and other fields. As one of the core components of the axial piston pump, the rotor system is inevitably eccentric and unbalanced due to factors such as structural constraints, processing effects, and external loads. Under high-speed and high-pressure working conditions, the cylinder pose of the traditional axial piston pump cannot be controlled, and instability such as cylinder overturning is prone to occur, which affects the reliability and life of the axial piston pump. [0003] The present invention proposes an active vibration control axial piston pump with magnetic bearing...
