Dynamic Balancing of the Shaft System of a Homemade 200MW Generator

以某厂的一台国产 2 0 0 MW汽轮发电机组为例 ,着重介绍了对国产 2 0 0 MW汽轮发电机组轴系的现场振动分析及动平衡处理的方法、步骤。通过动平衡处理及振动分析 ,发现了影响该机组轴系异常振动的各种因素 ,并提出了改进措施 ,取得了较好的效果 ,其结论对类似机组具有一定的启发作用。

In this paper,based on the exceptional vibration of the shaft system of a homemade 200MW generator of a power plant,a method and the steps of the on line process of the vibration for the balancing of the shaft system of a 200MW generator are described.During the on line process, the various factors affected the vibration are analyzed,some measures for reducing the vibration are taken,and satisfactory results are obtained. The conclusions derived in this work would be of reference value to similar systems.
