摘要
阐述了汽轮机轴承由于润滑油供油不足而引起低频振动的现象和机理;用3个实例说明了汽轮机转子振动原因的判断方法,并总结了供油不足引起的5个振动特征。
The phenomenon and principle of low frequency vibration caused by shortage of lubricant in the turbine bearings have been described. Diagnostic ways of vibrating reasons for the turbine rotor have been demonstrated with three examples and 5 vibrating features caused by shortage of lubricant have been summarized in the article.
