滴灌区加压泵站设计问题探讨

Research on the Design of Pressure Pumping Stations for Large Drip Irrigation Systems

从滴灌工程设计原理和运行制度出发,分析了大型滴灌区首部加压泵站的流量变化特点和扬程构成因素,指出了该泵站扬程设计的复杂性,提出了加压泵站设计流量和扬程的计算方法以及选泵原则和泵站进水池设计要求。

According to the principles of designing drip irrigation projects and the scheme of operating projects,the varied discharge of pressure pumping stations is analyzed in addition to components of pumping station head for a large drip irrigation system.A complicated process is stated for design pumping station head.The methods calculating the designed discharge and head are developed for the pressure pumping stations and the principles are proposed to select pumps and design inlet structures.
