【 摘 要 】

The motor driving end vibrates when there is no-load test run after overhaul of condensate pump of power plant unit; Through fault diagnosis and analysis, reasons for vibration were checked and solution found. The main reason is that the condensate pump motor magnetic force center line is not centered. The condensate pump motor is disassembled, then the reason of magnetic forcce center line is not centered was found and solution. Potential equipment safety hazard was eliminated successfully.
