摘　　要：为了论证1000 MW机组蜗壳式循环水泵高低速改造项目的技术经济性,以安徽某电厂在1000 MW机组首次应用的蜗壳泵式循环水泵为对象,拟将一台机组中的三台循环水泵中的两台改成具备低速运行的功能,通过AFT软件Fathom模块建模计算,证明改造方案是可行的。In order to demonstrate the technical economy of the high and low speed retrofit project of the volute circulating pump for 1000 MW units, two of the three circulating pumps in a power plant in Anhui Province are proposed to be converted into low speed circulating pumps. The retrofit scheme is proved to be feasible by the modeling calculation of the Fathom module of AFT software, and the retrofit proposal is proposed.
