压力罐供水方式在农村小型供水工程中的应用

摘要

In recent years,the project of rural water supply is developed rapidly,but due to the lack of in-depth analysis in some areas,the unreasonable water supply patterns and equipment matching as well as the poor management make the project not playing a proper role.Here,the pressure tank water supply mode more applicable for small-scale rural water supply project is proposed by comparing with the traditional water tower and direct water supply mode.Then,the working pressure and volume determination method as well as the type and selection of the pressure tank and water pump are given combining with the cases of water supply project.In addition,some operational problems are analyzed,and some refer-ences are provided for the design and operation management as well as the application and extension of the pressure tank water supply mode in rural water supply projects.%近年来，农村供水工程发展迅速，但一些地区由于缺乏对工程的深入分析，供水模式和设备选配不合理，管理不善，使工程不能发挥应有的作用。通过对压力罐供水方式与传统的水塔供水、直供式供水的特点进行比较，提出了压力罐供水方式更适宜于农村小型供水工程。通过工程实例给出了压力罐工作压力与容积的确定方法；并对运行中的一些重要问题进行了分析，为压力罐供水方式在农村供水工程中的推广应用、设计和运行管理提供了参考。
