本文用数学解析法分析时针式和平移式喷灌机管道上的流量分布,压力分布以及管道上各点的喷头和调压孔配置等实际问题。数学解析法是假设沿输水管均匀地布置许多小喷头,输水管延伸到灌溉地块的边界处,列出微分方程然后求积分以获得流量和压力的分布规律。采用这种方法的优点是可以用于喷头间距变化或不变的任何机组。并从平移式多孔管的压力和流量分布规律,得到多孔管道的设计方法,也就给管道式喷灌系统的正确设计,提供了理论依据。
In this paper, the mathematical analysis method is used to analyze the flow distribution, the pressure distribution and the nozzle and surge port configuration in the pipe of the hour and translation sprinkler. The mathematical analysis method assumes that many small nozzles are uniformly arranged along the water pipe. The water pipe extends to the boundary of the irrigation plot. The differential equations are listed and then integrated to obtain the distribution of flow and pressure. The advantage of using this method is that it can be used with any unit with a constant or constant nozzle spacing. And from the pressure and flow distribution of the translating multi-hole pipe, the design method of the multi-hole pipe is obtained, which also provides the theoretical basis for the correct design of the pipe sprinkler system.
