the abnormal vibration data of air-preheater's motor of unit no.1 in Meizhouwan Thermal Power Plant have been collected and analysed
result shows that the inner ring and the supporting frame of the deep-groove ball bearing have been severely damaged.The early failure information of equipments can be found by using the vibration velocity spectroscopic method
providing scientific data basis for repair known in advance.
