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。
In operation of 6 × 14 CSB - 4 type turbine - driven feed - water pumps, troubles such as wornout between movable and stationary 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.
