300 MW双水内冷汽轮发电机组振动故障处理浅谈

Vibration Fault Treatment of 300MW Double Water Inner Cooled Turbo Generator

某电厂#2机组在整套启动过程中出现了一系列故障及振动问题,如发电机风挡与轴颈摩擦、#5轴振大、发电机转子冷却水路堵塞等,对机组出现的振动故障进行逐一分析并提出解决处理方案。

In the starting process of #2 unit of a power plant, a series of faults and vibration problems appeared. For example, the friction between generator windshield and bearing, the serious shaft vibration of #5, the watercourse blocking of the rotor cooline and so on. Some analyses are made on the vibration faults of the unit and 10ut forward a scheme on how to deal with it.
