Abstract

The invention provides a detection method and device for a protective bearing of a magnetic suspension bearing, relating to the technical field of equipment detection, including: controlling the rotor of the magnetic suspension bearing to perform circular motion along the edge of the protection bearing in the magnetic suspension bearing; The voltage value of the position sensor, wherein the voltage value is used to represent the position information of the rotor; based on the voltage value, the position point of the rotor is determined; based on the position point of the rotor and the preset motion trajectory, it is determined whether the protective bearing of the magnetic suspension bearing is damaged. Among them, the preset motion trajectory is used to represent the motion trajectory of the rotor when the protective bearing of the magnetic suspension bearing is not damaged, which solves the technical problem in the prior art that it is necessary to manually detect whether the protective bearing of the magnetic suspension bearing is damaged, resulting in low detection efficiency.

Description

technical field [0001] The invention relates to the technical field of equipment detection, in particular to a detection method and device for a protective bearing of a magnetic suspension bearing. Background technique [0002] In the current design and application process of magnetic suspension bearings, magnetic suspension bearings need to be installed with protective bearings to ensure that the rotor is not subject to major damage when it falls at high speed due to accidents such as unexpected power failure during high-speed rotation. However, in the case of the existing technology, whether the protective bearing is damaged can only be checked and confirmed by manual disassembly and assembly, and the disassembly process is complicated, and the gap between the magnetic suspension bearing and the rotor may change due to the disassembly of the protective bearing, resulting in a change in the consistency of the position sensor. Difference. It is necessary to manually detect ...
