摘要 為了使水資源在農(nóng)業(yè)灌溉中的有效利用 開發(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)計建立了現(xiàn)代化的農(nóng)業(yè)噴灌模型 通過設(shè)計計算 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)中使用多個不同的噴管 則可根據(jù)噴管中噴嘴 的直徑不同來控制水的流量 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 of irrigating This design sets up the modernized agricultural sprinkling irrigation model because the area of every belt area is different the flow of the necessary water is differen t Using a lot of different nozzle among sprinkling irrigation system it is possible to make round sprinkling irrigation of district even according to nozzle with controlling the flow of water diameter of spray nozzle in addit ion 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 揚程 沿程阻力 局部阻力 Key words flux
