摘　　要：华能南京电厂 2号机组 ( 32 0MW )存在严重的振动不稳定隐患 ,通过对该机组轴承相对标高变化及振动的测试分析 ,得出轴系标高不合理是引起该机组振动的主要原因之一。论述了相对标高测量原理及标高和振动测试分析结果。给出了冷态下轴系标高调整方案 ,彻底解决了该机组存在的不稳定振动。Serious vibrating instability problem exist in No.2 unit(320MW) of Huaneng Nanjing Power Plant. By test and analysis, includes changes of relative bearing elevation and vibration, it is found that shafting elevation is unreasonable. This is one of primary factors that brings vibration of turbo-generator. In this paper, the measuring principle of relative elevation and the analytical results of elevation and vibration are discussed. The adjustment project of shafting elevation is presented. Unstable vibration is eliminated thoroughly in this turbo-generator unit.
