摘要
总结了几年来宝鸡第二发电公司2号300MW汽轮机高中压转子振动故障诊断的处理经验,认为机组振动问题除先天不足外,主要表现为热态振动问题。热态下振动主要是由高中压转子存在一定的热弯曲和高中压汽缸及前箱存在跑偏引起的,通过改变轴瓦形式、相对标高及高速动平衡,使机组振动达到良好水平。
This paper summarizes HP & IP rotor vibration fault diagnosis and treatment in recently years at Baoji Power Generation Corporation Ltd. Phase Ⅱ. Besides congenital defect, the main reason is hot vibration. Certain hot winding exited in HP & IP rotor and deviation between HP & IP cylinder and front case have caused the hot vibration. Changing of bush type, relative elevation and high-speed dynamic balance can make unit reach good operation level.
