Abstract: Abstract:Taking the 1000MW generator set of a power plant as example, the monitoring data of vibration of each bearing during commissioning period were analyzed, and it was found that the vibration of the bearing bush No.7 exceeds standardpermitted value. According to investigations of startup process repeatedly, the reason of the vibration was found. The targeted measures were adopted, and the problem of vibration of bearing bush No.7 was solved.
