Abstract:Serious vibrating instability roblem exist in No.2 unit(320MW)of Huaneng Nanjing Power Plant.
By test and analysis, includes changes of relative bearing elevation and vibration, it is found that shafting eleva-
tion is unreasonable.This is one of rimary factors that brings vibration of turbo-generator.In this a er, the
measuring rinci le of relative elevation and the analytical results of elevation and vibration are discussed.The
adjustment roject of shafting elevation is resented.Unstable vibration is eliminated thoroughly in this turbo-
generator unit.
Key words:turbo-generator unit;elevation;bearing;vibration
