低压多孔均匀出流灌溉软管的试验研究

The Experimental Investigation of Irrigation Flexble Pipe with Low Pressure Many Poles and Uniform Outflow

本文提出了一种结合低压管道输水灌溉和膜上灌的多孔均匀出流软管的灌溉系统．经过试验研究，给出了在不同工作压力和流量条件下的多孔均匀出流灌溉软管的管径、出水孔径和最大输水长度的求解图．

In order to improve the water-utilization ratio with draul for irrigation and to make the surface irrigation system more perfect. The article put forward an irrigation system of flexible pipe with many poles and uniform outflow, in which low pressure delivery pipe irrigation is combined with on-film surge flow irrigation. At the same time,a great deal of experimental investigation has been done also has been designed the pipe-diameter or irrigation flexible pipe with many poles and uniform out now on the condition of various work pressure and discharge,the outlet diameter and the answer picture of the max delivery length.
