摘要:為了使水資源在農(nóng)業(yè)灌溉中的有效利用,開(kāi)發(fā)新型的農(nóng)業(yè)節(jié)水灌溉系統(tǒng)可克服傳統(tǒng)灌溉方式的不足,本設(shè)計(jì)建立了現(xiàn)代化的農(nóng)業(yè)噴灌模型,通過(guò)設(shè)計(jì)計(jì)算,由于各環(huán)行區(qū)域的面積不同,所需的水的流量不同,在噴灌系統(tǒng)中使用多個(gè)不同的噴管,則可根據(jù)噴管中噴嘴的直徑不同來(lái)控制水的流量,從而使圓區(qū)的噴灌均勻,另外,采用鑄鐵管路大大減少了水的損失.在噴管系統(tǒng)中采用集中控制,自動(dòng)化程度高,易于調(diào)節(jié).Abstract : For making water resource valid used in agricultural irrigation ,to develop new-type agricultural water-saving irrigation system can overcome the shortcomings of the traditional way ofirrigating .This design sets up the modernized agricultural sprinkling irrigation model. because the areaof every belt area is different, the flow of the necessary water is different. Using a lot of different nozzle among sprinkling irrigation system, it is possible to make round sprinkling irrigation of district even, according tonozzle with controlling the flow of water diameter of spray nozzle ,in addition , it casts the iron pipe distance and reduces losses of ink greatly to adopt. Adopting centralized control in the nozzle system, the automatic degree becomes high and easy to regulate . 關(guān)鍵詞:流量,作用水頭,壓力,流速,揚(yáng)程,沿程阻力,局部阻力Key words: flux
