主油泵齿式联轴器故障分析
摘要
针对多起汽轮机主油泵齿式联轴器(简称为主油泵联轴器)频繁磨损
导致频繁检修甚至事故停机的问题进行了分析。从汽轮机组对主油泵联轴器性能的要求
分析主油泵联轴器的运动规律查明联轴器频繁损坏的原因
提出了主油泵联轴器故障的处理方案和预防措施
同时对使用该型主油泵联轴器的机组的检修维护提出了建议。
Abstract
Directing against the problem of frequent wornout on tooth-type coupling of the main oil pumps
which resulted in frequent repairs
and even in emergency shutdown of units
the causes have been analysed.Starting with the moving pattern of tooth-type couplings
the requirement of turbine unit for characters of the said couping has been studied
and eliminating scheme and preventive measures for tooth-type coupling damage being put forward
so as to ensure safe operation of the main oil pumps
at the same time
some recommendations for repair and maintenance of units adopting tooth-type coupling for the main oil main oil pump being proposed.
