Design of Small Lift Irrigation Station in Hilly Area of Sichuan
-
摘要:
根据作物的用水定额和灌溉面积等计算灌溉需水量，确定了小型提灌站泵的流量、扬程等相关参数，通过管径计算确定了输水管道直径，并根据相关参数设计了小型提灌站，为基层工作人员提供借鉴参考。
Abstract:Irrigation water demand was calculated according to water quota and irrigation area of crops．Flow, head and other relevant parameters of pump of small lifting irrigation station were determined．Diameter of water transmission pipeline was determined through pipe diameter calculation．Small lifting irrigation station was designed according to relevant parameters, so as to provide reference for grass-roots staff．
