摘　　要：北重某330 MW机组几次冷态起动过程中,3号轴瓦振动突升,引起振动异常的主要原因是3号轴瓦载荷过轻及存在动静碰摩,经小修调整轴瓦间隙及清理轴承油挡,3号轴瓦振动恢复正常,建议对机组轴系标高进行复查调整。The paper makes analysis on 3# bearing vibration phenomenon during a certain 330MW unit＇ s several cold starting produced by BEIZONG Steam Turbine Generator Co. , Ltd, the reason of the vibration is the lower load and the static and dynamic friction on the 3# bearing, after adjusting beating gap and clearing bearing oil gear, the bearing gets normal operating, and the beating elevation should be adjusted.

关 键 词：振动 载荷 动静碰摩
