【 摘 要 】

The driving end of B steam feed pump vibrates greatly when steam turbine is in normal operation. Through fault diagnosis and analysis, reasons for vibration were checked and solution found. It mainly caused by mass imbalance of feed pump rotor. A kind of solution has been proposed, and potential equipment safety hazard were eliminated successfully.
