摘　　要：通过对某电厂一台汽轮机启动过程振动数据的分析,判断出造成低压转子轴承振动大的主要原因是转子质量不平衡。采用高速动平衡的方法,使低压转子在开、停机过临界及3000r/min时的轴承振动均达到优良标准。Through the analysis of a certain power plant a steam turbine vibration of the start-up process data, think that main reasons of low-pressure rotor bearing vibration big is rotor mass unbalanced. By using method of high-speed balancing, In up speed over critical and down speed over critical and 3000r/min, bearing vibration of low-pressure rotor achieves high standards.
