高坝洲水电站3#机组振动分析及处理

Analysis and Solution on the Vibration of Unit 3# Hydrogenerator for Gaobazhou Hydropower Station

本文就高坝洲水电站3#机组振动摆度超标原因作了深入地分析，对转子圆度处理方法作了 有益的探讨，论述了上端轴加垫校正机组轴线的方法，取得了一定经验。对现场检查手段及 转子圆度验收标准的制订提供了参考。

The reason for exceeding admissible limit of the vibration runout of unit 3# h ydrogenerator for Gaobazhou hydropower station was presented.Which is useful to approach on the solution of the rotor roundness.A way for correcting the hydroge nerator shaft line by inserting shims on upper-shaft was described and some exp erience was achieved.Reference for site inspection measurement and make out a ac ceptance standard of rotor roundness was provided.
