SHAFTING VIBRATION ANALYSIS AND OPTIMIZATION FOR A 135 MW TURBOGENERATOR UNIT
摘要
介绍了某电厂2号汽轮发电机组的轴系振动情况
分析认为机组振动的主要原因为一阶不平衡及转子热变形。通过转子动平衡
消除了机组的振动故障
使振动达到优良水平
保证了机组的安全运行。
Abstract
This paper analyzes the vibration problem of No.2 135 MW turbogenerator unit in a power plant
and find that the vibration is mainly due to the first-order unbalance and thermal deformation of the rotor.After dynamic balance of the rotor
the vibration fault of the generating unit is eliminated with a better vibration grade to achieve safe operation of the generating unit.
