一、前言水轮发电机组在运转中受着来自水、机、电等多种力的作用,因而引起轴承支座发生振动,其振动值的大小反映着诸力的大小。要想消除振动,使机组能稳定地运行,那么就必须设法消除诸力的影响。当机组产生过大的振动时,应当进行认真地分析检查,把各种可能出现的因素归列排队,抓住主要矛盾,逐一分析研究,找出振动的原因,加以处理。 First, the foreword Hydro-generator set in operation by a variety of forces from the water, machinery, electricity and so on, resulting in bearing bearing vibration, the size of the vibration value reflects the strength of the size. In order to eliminate vibrations and keep the unit running stably, efforts must be made to eliminate the effects. When the unit produces excessive vibration, it should conduct careful analysis and inspection, line up all kinds of possible factors, grasp the main contradictions, and analyze and study one by one to find out the reasons for the vibration and deal with it.
