【摘要】 从系统分析的观点出发，以管网结点平衡方程为基础，建立了求解喷灌管网系统内各类水力单元直至全系统水力特性的数值计算模拟模型，给出了求解方法．经实际工程验证，模拟计算结果能如实地反映了喷灌管网水力特性的客观规律，从而为设计喷灌管网系统、喷灌加压泵的选型配套及优化运行等提供了可靠的快速计算方法更多还原

【Abstract】 This anicle presents the numerical￣atone models describing the hydraulic charactendcs of SIPS abjectly pressured by pUIDPs. The sedative models of nUmerical calculation on the hydraulic characteriStics of an adds of hydraulic aams and the whole Systems and the corresponding calculation methods ard eStabithed from the viewpoint ofghem analysis on the basis of pipeline-web nodes balancing equation.As proved by practical engheehog, the results of sinnilathie calculation reflect accurately the law of the hydraallc characteristics.of SIPS. Thus, a reliable and rapid calculation method is provided for the design of SIPS and the discussion on of reasonable choice and the strovements of operation ofpressuhag pUmps.更多还原
