摘要
发电厂循环水泵房旋转滤网的冲洗水泵通常为自吸立式长轴式,运行中故障率较高。经过分析与计算,将其改造为单级离心水泵,从冲洗水泵改造前后各参数的对比及稳定运行情况来看,冲洗水泵的改造效果良好。
The wash-water pumps for the rotary filter screens in the circulating water pump house of the power plant is usually vertical self-priming long shaft type. The failure rate is high in operation. Through the analysis and calculation, this paper transforms the pumps into single-stage centrifugal ones. The parameter comparison before and after the retrofit and stable operation show that the retrofit achieves great effect.
