Diagnosis and Identification of Vibration Accident for Hydrogenerator Unit

振动是影响水轮发电机组正常运行和危害机组寿命的主要故障。要清除机组振动故障 ,必须寻找引起机组振动的原因。本文主要介绍如何依据诱发机组振动的某些特征 ,捕捉其振动原因。为简化问题 ,不考虑引起机组振动诸因素间的相互影响 ,但对分析机组振动的主要原因 。

Vibration is the main accident that affects the normal function of hydrogenerator unit and endangers the life span of hydrogenerator unit. To eliminate the vibration accident of the unit, it is necessary to detect the causes that lead to the vibration of the unit. This paper intends to discuss the causes resulting in the vibration of the unit, revealed by some characteristics of the unit vibration. For the sake of simplifying the program, the interaction of the factors causing the vibration of the unit was not considered in this paper. However, it is helpful for the analysis of the main reasons of the unit vibration.
