    滴灌系統的維修和保養

    文字:[大][中][小] 手機頁面二維碼 2017/9/18     瀏覽次數:    


      滴灌系統是一套精密的灌溉機械裝置,許多部件為塑料制品。因此,在使用操作過程中一定要小心,不可猛力扭動各個旋鈕和開關。在打開各個容器時,注意將一些小部件的位置記好,并防止丟失,以便依樣安回。



      1.灌溉季節開始前的維修保養


      1.1過濾器部分 在介質過濾器首次灌溉開始前,在罐內注滿水并放入1包氯球,擱置30分鐘后,按正常使用方法各反沖1次,此反沖可預先攪拌介質,使之顆粒松散接觸面展開。之后,充分清洗過濾器的所有部件,緊固所有的螺絲。


      1.2檢查肥料罐或注肥泵的零部件及與系統的連接是否正確,清除罐體內的積存污物,以防其進入管道系統。


      1.3檢查所有的末端豎管,看是否有折損或堵頭丟失情況,若有則及時修理和補充。


      1.4檢查所有的閥門與壓力調節器及其連接微管,若有缺損應及時修補。


      1.5關閉主支管道上的排水底閥。


      2.每個灌溉季節結束時的維修保養


      2.1全系統高壓清洗 按輪灌組順序分別打開各支管和主管的末端堵頭,開動水泵,使用高壓力逐個沖洗,力爭將管道內的污物沖洗干凈,然后把堵頭裝回。


      2.2過濾系統 在管道高壓清洗結束后,充分清洗過濾器后排凈水。


      2.2.1若過濾器是帶有砂石分離器的疊片式過濾器,先把各個疊片組清洗干凈,再用干布將塑殼內的密封圈擦干放回。然后,開啟集砂膛一端的絲堵,將膛中積存物排出,將水放掉。再將過濾器壓力表下的選擇鈕置于排氣位置。


      2.2.2若過濾器是介質過濾器,先打開過濾器罐的頂蓋,檢查砂石濾料的數量,并與罐體上的標識比較,若數量不足要及時補足,以免影響過濾質量。若砂石濾料上有懸浮物,要撈出。同時,應在每個罐內加入1包氯球,放置30分鐘后啟動,每罐各反沖120秒2次,然后打開過濾器的蓋子和罐體底部的排水閥,將水全部排凈。再將過濾器壓力表下的選擇鈕置于排氣位置。若罐體表面或金屬進水管路的金屬鍍層有損壞,應立即清銹并重新噴涂。


      2.2.3若過濾器是介質過濾器并帶有疊片式二級過濾器,應在重復2.2.2的基礎上,將疊片清洗干凈,并擦干殼內的密封圈。


      2.3施肥系統 在進行維修時,關閉水泵,開啟與主管道相連的注肥口和驅動注肥系統的進水口,排去壓力。


      2.3.1若施肥器是注肥泵帶有塑料肥料罐,先用清水洗凈肥料罐,打開罐蓋晾開。再用清水沖凈注肥泵,然后分解,取出注肥泵驅動活塞,用隨機所帶的潤滑油涂在部件上,進行正常的潤滑保養,然后拭干各部件,重新組裝好。


      2.3.2若使用注肥罐,應仔細清洗罐內殘液并晾干。然后,將罐體上的軟管取下,用清水洗凈,置于罐體內保存。


      2.4田間設備 在冬季來臨前,為防止嚴寒將管道凍壞,北方地區應注意三點。


      2.4.1把田間位于主支管道上的排水底閥打開,盡量將里面的水排凈,閥門冬季不必關閉。


      2.4.2將田間各閥門的于動開關置于開的位置。


      2.4.3將田間各條滴灌管線拉直,勿使其扭折。若冬季回收,也應注意勿使其扭曲放置。
