摘要

6×14CSB-4型汽动给水泵在运行中出现动静部件磨损(包括支持轴承)、平衡盘磨损、推力轴承烧损、机械密封泄漏等故障。根据故障分析结果

对给水泵平衡盘

进口滤网、磁性分离器、密封水冷却器等部件进行了改造

改后有效降低了给水泵故障率。

Abstract

In operation of 6×14 CSB-4 type turbine-driven feed-water pumps

troubles such as wornout between movable and sta- tionary parts (including bracket bearing)

wornout of balancing disc

burnout of thrust bearing

leakage of mechanical seal

etc.have occurred.For these

analysis has been carried out in detail.Based on results of analysis

some parts of the said feed-water pumps

such as balancing disc

magnetic splitter

sealing water cooler

etc.have been retrofited.Combining with operation measures

the failure rate of said feed-water pumps has been effectively reduced.
