Abstract

The invention discloses a fault diagnosis method of abnormal vibration, of a rotor, caused by a floating oil retainer. The fault diagnosis method of abnormal vibration, of a rotor, caused by a floating oil retainer includes the steps: importing shafting TSI data into a fault diagnosis system; setting a threshold, utilizing a spectrum analysis method, determining whether the property of shafting abnormity vibration belongs to common forced vibration, extracting typical characteristics of a fault, analyzing operating parameters of a set, and eliminating the influence of load, thermal deformation and field current; and with combination of shafting structure analysis structure, determining whether abnormal vibration of the rotor is caused by a floating oil retainer, and then obtaining a diagnosis result. The fault diagnosis method of abnormal vibration, of a rotor, caused by a floating oil retainer has the advantages of being comprehensive in the considered extracted characteristics, being suitable for field fault diagnosis, being quick and accurate in result diagnosis, and having practicality and operability.

Description

technical field [0001] The invention relates to a fault diagnosis method for abnormal vibration of a rotor caused by a floating oil gear. Background technique [0002] The floating oil gear of the turbogenerator is a new type of oil gear. Compared with the traditional fixed oil gear, it can change with the position of the rotor to a certain extent, and always follow the rotor. Theoretically, there will be no gap. Uniform and oil leakage. At present, there are few practical applications, and there are few cases of abnormal vibration faults caused by floating oil gears, which often bring certain difficulties to fault diagnosis. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a fault diagnosis method for abnormal vibration of the rotor caused by the floating oil gear. The present invention uses typical data as the analysis basis, and has typicality, practicability and operability. [0004] In order to achieve the above...
