摘要

某电厂两台600 MW空冷机组在起动过程中均发生了多次动静碰磨

通过检修和磨合消除了该摩擦振动。同时

在带负荷过程中

这两台机组的7号轴承处轴振动(7号轴振)均随负荷变化而大幅波动

采用现场动平衡技术对低压转子-发电机转子联轴器对轮(低-发对轮)、低压2转子同时加重

处理后机组振动可控制在优良水平。

Abstract

Impact-abrasion between moving and stationary parts in 2×600 MW air-cooled units of one power plant has frequently occurred in the start-up process

and the said impact-abration being eliminated through repair and runing-in measures.At the same time

during the process of taking load

the shaft vibration at bearing no.7 of the said two units had a substantial fluctuation with the load change.By using the dynamic balancing method in the field

the trial weights are simutanuously added onto coupling between LP rotor and generator

as well as onto two LP rotors

thereby

the vibration of units can be controlled to a satisfied level.
