| Abstract: | Irrigation system of low pressure delivery pipe lines is compos of wells, pumps and pipelines. On the basis of the operation characteristics of such system this paper analyzes the change of efficiency of comprehensive unit. And on the basis of the concept of design of delivery pipe network to this paper studies the reasonable assortment of pipe network and well-pump. The factors of pump lift and pump price have been considered comprehensively in design, thus making whole irrigation system work under the economical and energy-saving condition and making the system have minimum yearly cost. |
