Abstract

The invention provides a detection method and device for a protective bearing of a magnetic suspension bearing, and relates to the technical field of equipment detection, and the method comprises the steps: controlling a rotor of the magnetic suspension bearing to carry out the circular motion along the edge of the protective bearing in the magnetic suspension bearing; according to the preset frequency, collecting the voltage value of the position sensor, wherein the voltage value is used for representing the position information of the rotor; determining a position point of the rotor based on the voltage value; and determining whether the protective bearing of the magnetic suspension bearing is damaged based on the position point of the rotor and a preset motion trail, the preset motion trail being used for representing the motion trail of the rotor when the protective bearing of the magnetic suspension bearing is not damaged. The problem that whether the protective bearing of the magnetic suspension bearing is damaged needs to be detected manually, and the detection efficiency is low in the prior art is solved.

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 ...
