摘　　要：给水管道加压方式的选取需考虑供水安全性、方案可实施性、运营管理及建设的经济性等多种因素。传统的加压方式多选用清水池配加压水泵进行加压。近几年,无负压供水在建筑小区供水中应用较多,市政输水管道采用无负压供水也有一定的应用。文章结合工程实例将传统的清水池加水泵的供水方式与无负压供水方式进行比较,选取了无负压系统作为小范围输水管道的二次加压系统,为其它类似工程的设计提供参考。The selection of pressurization mode of water supply pipeline needs to consider many factors,such as water supply safety,scheme enforceability,economicalefficiencyofoperation and construction.The traditional pressurization method mostly selects the clean water tank with pressurized water pump for pressurization.In recent years,non negative pressure water supply is widely used in the water supply of building communities,and the non negative pressure water supply also has a certain application in municipal water transmission system.In this design,the traditional water supply system is compared with the non negative pressure water supply system,and the non negative pressure system is selected as the secondary pressurization system of water transmission pipeline,which provides a reference for the design of other similar projects.
