清镇电厂7号机组改造后高速动平衡概述

The Brief Description of Balance Moving of Unit 7 in Qingzhen Power Plant

贵州清镇发电厂 7号汽轮机组大修改造后 ,启动过程中 1～ 3号瓦振动在过临界及 3 0 0 0r/min时均超标。经过几次高速动平衡试验 ,在中压末级和接长轴上进行加重 ,基本消除了各瓦在过临界及 3 0 0

During the running up of unit 7, the vibration of bearing No.1,No.2,No.3 is too high at the critical speed and 3?000 r/min . After several times balance moving. Weights added on the last stage of IP and on the joint shaft to dismiss the vibration at the critical speed and 3?000 r/min .
