根据多水源环状管网供水系统的组成及布置,本文提出水头平衡法作为解环方程组的基础,得到不同组成的环平差流量计算关系,用以求解各水源的供水量、各管段的流量及各节点的水头值。用FORTRAN77算法语言编制了计算程序。算例计算表明,使用方便,可对多水源环状管网供水系统进行多种工况计算,并能得到满意的结果。
According to the composition and arrangement of the water supply system of the multi-water source circular pipe network, this paper proposes the head balance method as the basis for the solution of the ring equations, and obtains the relationship between different composition of the ring adjustment flow calculation to solve the water supply quantity of each water source and each pipe segment. Flow and head of each node. The calculation program was compiled with FORTRAN77 algorithm language. The calculation of the calculation example shows that it is easy to use, and it can be used to calculate multiple working conditions for a multi-water source circular pipe network water supply system, and satisfactory results can be obtained.
