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).
