在供热锅炉房中二级循环泵的应用（In the application of heating boiler room two circulating pump） In the heating boiler room two stage circulating pump application,.Txt likes me, this is revolutionary need, knows?! You cant fold your clothes while you stay! Ill fold it later! I must give you happiness, who do not want to stop. Application of two stage circulating pump in heating boiler room Langfang economic and Technological Development Zone heat supply center Gu Xiaobo Langfang Xianghe County Thermotics Inc Phoenix Dragon King Jian Dong [Abstract] this paper introduces the circulating water pump of the boiler room is divided into to overcome the boiler room boiler water circulating pump, boiler and pipe resistance and local resistance to overcome the external resistance and user resistance of circulation pump, take the two functions of the pump are respectively arranged and mutually connected through the design concept, and through the actual operation of the design according to the concept of two seat heating boiler in the boiler combustion and improve the energy saving practice experience. Key words: boiler room heating; two stage circulating water pump; current limiting valve; energy saving 1 Preface The circulating water pump of heating boiler room is the heart of the heating system. It takes on the function of driving heat medium to transmit heat energy, and whether the equipment matching is reasonable or not directly influences the conveying effect and energy consumption. In order to realize the energy saving operation of the heating system and reduce the heating cost, it is necessary to analyze, discuss and improve how to select and how to configure the circulating water pump. 2 selection principle and existing problems of traditional circulating water pump The traditional selection of circulating water pump is usually a few pumps in parallel into a group of pumps, at the same time to meet the boiler room, heat supply network and heat user flow and lift demand, can be called
