技術詳情
該技術關鍵部件——“雙面齒形高效能內鑲片式灌水器”,采用高溫下模具一次注塑成型,制造偏差小于1%,紊流流道的結點處倒角R大于 0.2mm。選擇U型出水孔,提高滴頭抗負壓堵塞性能;采用雙面流道 對稱結構,提高滴頭揀選精度,減少反片、倒片及產品故障率。優化結構參數和注塑材料及加工工藝,提高過濾器吸污能力、傳動效率和其強度等級;加設過濾器壓差報警器系統,實現實時監控,及時清潔的目的。與常規滴灌相比,節水55.6%,節肥22.6%,能耗降低12.8%, 年運行費用降低16.0%,單方水運行費用為1.24元,降低0.44元。
技術優勢

己在天津、河北、河南、內蒙、廣西、甘肅等16個省區推廣轄射面積 183萬畝,累計節約農業用水量38.47億m3。

適用對象

經濟作物、糧食作物、林果及溫室等高效水肥一體化灌溉
