摘　　要：某电厂660MW超临界机组2号机组B给水泵汽轮机自投入运行一段时间后多次发生突发性异常振动。经过对该给水泵汽轮机进行变油温试验以及全程振动测试分析,提出了振动处理方案并在大修中实施。经处理后该给水泵汽轮机振动故障消除,可靠性得到了提高。Sudden abnormal vibrations have occurred for many times in auxiliary engine B of the No. 2 600 MW ultra-supercritical unit in a power plant since its operation for a period of time. Through variable oil temperature test, diagnostic analysis and vibration measurement of the feed pump turbine, a vibration treatment scheme is provided and implemented during overhaul, after which the vibration faults are finally eliminated, while the reliability of the feed pump turbine is improved.
