| Abstract: | Electromotor on oil platform often has mechanical failures.In order to achieve monitoring and diagnosis of the electromotor,common diagnostic methods of electromotor are summarized first,and then vibration monitoring is regarded as a suitable method for monitoring and diagnosing of mechanical failures by comparing the advantages and disadvantages of each method and characteristics of mechanical faults.At last,the fault frequencies and arrangements of vibration measuring points are analyzed.By using vibration monitoring method,the diagnosis of bearing faults of electromotor is carried out.The results show that the analysis of condition monitoring methods for electromotor is meanning for machine maintenance and repair,and it lays foundation for computerized repair system and resource management system. |
