【Abstract】 Based on the theory of rotating machinery frequency spectrum diagnosis, the vibration intensity and vibration wave spectrum characters of common faults of the fan are analyzed.Frequency spectrum analysis and phase analysis are used interchangeably to analyze the collected signals of the working fan and to diagnose such vibration faults as loose sliding bearing,unbalanced rotors,non alignment shafts.Finally,some countermeasures are presented.更多还原
