摘要

永济热电厂一台北京重型电机厂早期生产的N5 0 8.83Ⅱ型汽轮机

运行后推力轴瓦严重超温。分析认为超温主要由转子轴向推力过大引起

经采取多项措施改进后

获得了较好的效果

Abstract

Serious over-temperature occurred on thrust bearing shoe of a N508.83-II type unit manufactured by Beijing Heavy-duty Electric Machine Factory

and was in operation at Yong ji Thermal Power Plant has been analyzed

it is considered that the main cause of said over-temperature to be the undue axial positive thrust of the rotor. After taking some measures

better results have been obtained.
