摘要
结合一台200MW机组长期轴振动故障实例,对振动现象进行了分析,指出了引发振动的原因主要为动静部分摩擦。
Combined with practical example of longterm shaft vibration trouble on a 200 MW unit, the vibration phenomenon has been analysed, pointing out that the causes leading to said vibration are mainly due to friction between movable and stationary parts, such as steam seal gland, and oilring retainer for bearings etc..
