摘要
针对某超临界空冷660MW机组不稳定振动的问题,分析机组异常振动情况,认为汽流激振是造成不稳定振动的主要原因,并提出处理措施。
To solve unstable vibration of one supercritical air-cooled 660 MW turbine,the abnormal vibration characteris-tics is studied.It＆#39;s found out that the primary cause of the ab-normal vibration is steam-induced vibration.The specific treatment is introduced.
