摘要

遵义发电厂 8号机给水泵轴封装置原来采用浮动环密封

该密封装置由于结构原理的限制

动静配合间隙小

对密封水水质、压力要求高

因此给水泵运行存在一定的安全隐患。经改用螺旋密封结构后

因其动静配合间隙大

故对密封水压力要求不高

取得了良好的经济效益和安全效益。

Abstract

A screw sealing technique is put forward and has been utilized in retrofitting the sealing of feed-water pump for unit No.8 of Zunyi Power Plant.Application of this technique has good economic and social benefits.
