摘要

某电厂1号引进型300 MW机组在试运时

3、4、6号轴承振动(瓦振动)过大。在完成168 h试运行后

利用小修消缺的机会

对机组振动原因进行诊断

认为振动是激振力过大所致。通过调整轴系平衡

使机组3 000 r／min和满负荷下各瓦轴振动、瓦振动达到了满意的水平。

Abstract

An imported type 300 MW unit no. 1 in one power plant had excessive vibration (bearing shoe vibration) of bearing no. 3. no. 4

and no. 6 in trial operation of the newly installed unit. After completion of 168 h trial operation

taking the opportunity of temporary repair for eliminating defects

diagnosis of causes for vibration troubles of said unit has been carried out. Through adjustment of shaft balancing

the shaft vibration and bearing shoe vibration of each bearing shoe under 3000 r/min and full load have all reached a satisfactory level.
