抽沙船由高壓水泵和吸沙泵組成，抽沙船利用船動力帶動水泵，產生高壓水流進入噴水管，高壓水泵把經高壓水槍沖擊水底的泥沙層，將沉積河底的淤泥吹攪成渾濁的水狀，泥沙飛濺泛起在吸沙龍頭周圍，經吸沙泵吸起由上吸管排到指定位置，這樣一噴一吸完成整個工作過程。
故障處理：如遇抽沙船堵管現象，首先要判斷清楚是異物堵轉還是機械堵轉，異物堵轉比較好處理，將水泵抽出來，清理雜物就OK了，機械堵轉比較麻煩，要檢查是葉 輪扣環(huán)磨嚓還是葉輪邊緣或者說泵軸磨嚓，口環(huán)處磨嚓，用拋光機將磨嚓部位進行切削打磨，其他部位應該先考慮泵軸是否變形，校軸在處理。
Suction dredger is composed of a high-pressure water pump and a sand suction pump, pumping sand the use of ship power driven pump, high pressure water flows into the water spray pipe, high-pressure water pump put by high-pressure water jets impact the bottom sediment layer, deposition of river silt blowing Jiaocheng muddy water, sediment splash thrown in the ceiling around the sand leading, the sand suction pump suction by straw on the row to the specified location, so a jet suction completed throughout the course of their work.

Failure treatment: in case of pumping sand plugging phenomenon, first to determine the clear foreign body stall or mechanical blocking, foreign body locked rotor better treatment, pump it out, clean up debris on the OK, mechanical blocking more trouble, to check is said grinding wheel blade retaining ring chow or the edge of the impeller and pump shaft grinding Jenna, mouth ring grinding Jenna, polishing machine for grinding Jenna parts cutting grinding and other parts should first consider the pump shaft deformation, shaft straightening in dealing with. |
