Abstract:

The cause analysis and treatment to the large vibration of #7 bearing of lowpressure cylinder in a 1000MW unit are made. Through the reinforcement of the condenser support pipe at lower part of lowpressure cylinder bearing, over vibration of the bearing is effectively solved. The scheme is simple, reliable and of low cost, which provides guarantee for the longterm safe and reliable operation of the unit and provides reference for relevant personnel.
