摘　　要：针对某电厂#3、#4机组凝结水泵存在的问题进行了抽叶轮改造,并对改造进行了可行性分析及节能分析。因在改造中涉及到水泵工作出力和系统的安全,因此确定抽取叶轮的级数和位置,压力余量和对精处理影响的分析就显得尤为重要,在进行大量参数分析后确定了最后的改造工序,经此改造后可直接降低厂用电率0.021%,降低供电煤耗0.06 g/kW.h,节电效果显著。Aiming at some problems for condensate pump in #3, #4 unit, it explained the penultimate vane wheel reconstruction and carry out the feasibility analysis and energy saving analysis of the reconstruction. Because the reconstruction involves the pump work output and system safety, it is particularly important that determine extraction impeller series,~position, pressure allowance and the influence of the fine processing of analysis. The final transformation process was determined after extensive parameter study. After the reform, the service-power consumption rate will directly reduce by 0.021%, the power Supply coal consumption will reduce by 0.06 g/kWh. Power saving effect will be remarkable.
