摘要
某厂2×350MW燃煤机组由上海汽轮机厂生产,2013年投入商业运行。2020年机组C级检修后冷态启动,汽轮机冲转暖机正常后定速3000rpm/min运行,3000rpm/min定速运行90min后,汽轮机轴瓦振动持续升高触发振动保护动作停机,通过分析及处理取得良好的效果,可为其他同类型机组相关问题提供借鉴。
The 2×350 MW coal-fired unit was produced by Shanghai steam turbine works.The unit was put into commercial operation at the end of 2013.After the annual overhaul of the unit in 2020,the turbine started at a constant speed of 3000 rpm/min,and the bearing bush vibration continued to rise,triggering the vibration protection action shutdown.Through the analysis and treatment,good results were obtained,which can provide reference for other similar units.
