摘要：When a power plant ultra-supercritical 1000MW steam turbine generator set was started in a cold state, the vibration value of NO.3 bearing bush exceeded the alarm value. Based on the mechanism of vibration, the fault diagnosis and troubleshooting of excessive vibration of the NO.3 bearing bush were carried out by consulting the historical operation trend and checking the maintenance records, and the cause of the fault was accurately analyzed. By adopting effective measures such as setting up the heating system of the middle pressure cylinder and setting up the starting steam parameters reasonably, the problem of excessive vibration value of the NO.3 bearing bush was completely solved and the hidden danger of equipment operation safety was eliminated.
