摘要
机组在整套启动时，首次启动发现汽轮机汽轮机轴振较大，5500r／min时，2号轴承大轴振动2Y约140—150μm，然后，进行振动分析和处理，机组轴系振动全部达到优良标准。
During the commissionning of the whole unit, when it firstly rises up to 5 500 r/min, the max. shaft vibration takes place, that is, No. 2 bearing vibrates 140 - 150μm in y direction. And then, the shaft vibration of the unit meets the requirements of the criterion by analyzing and disposing the vibration.
