Analysis of Energy-Saving Transformation of Water Pumps
This article provides an overview of the principles of pump energy saving technologies such as valve regulation,frequency conversion,impeller cutting and ternary flow,which are widely used today,as well as their application conditions and advantages and disadvantages.Combined with the actual operation of the high-pressure cooling water system of No.2 combined pumping station of No.2 blast furnace of Shougang,an energy-saving transformation program for the pumps was proposed,the design of ternary flow tech-nology for high-pressure pumps were determined,meanwhile,pump selection,head and flow rate accounting were carried out accordingly.The results show that the total power of the two pumps after the retrofit is 189 kW lower than the total power of the three pumps be-fore the retrofit,which saves 860,000 yuan in electricity costs per year with significant eco-nomic benefits.
