A method for servicing and routine maintenance testing of an aero-generator

Abstract

The application discloses a kind of methods for the repair and routine maintenance test suitable for aeronautical generator, comprising: S1, the aeronautical generator of appearance detection qualified is installed on the drag of test bench and adjusts good concentricity, starts drag and drives aeronautical generator rotation and detects the torsion of aeronautical generator when rotating, when torsion is greater than preset threshold, terminate test, when torsion is less than or equal to preset threshold, enter next step test, for ensuring that aeronautical generator shaft will not be damaged when testing;S2, the output cable of aeronautical generator is connected to the terminal of aeronautical generator body, and aeronautical generator is connected to test platform host computer, and the whole machine performance test of aeronautical generator is carried out;S3, after starting aeronautical generator whole machine performance test, the real-time temperature of aeronautical generator is collected at preset frequency, and the temperature rise rate under each working condition is calculated in real time, when temperature rise rate exceeds preset threshold, determine abnormality, for detecting the hidden defect caused by the wear of parts inside aeronautical generator.
