挖沙船的構成部分是有挖掘系統，操作部分，減速系統，船體，主架，動力，水下挖掘系統等部分，挖沙船是先將柴油機開動，把離合器拉開，然后發動柴油機，然后再把轉速調為正常，將沙子與沙子里面的雜質分開，通過輸送帶運輸出去，在送至岸邊。挖沙船適用于水庫，河道的砂石分離設備，有柴油機式和電動式兩種挖沙船。

   抽沙船適用于在大海，湖泊水庫等大區域作業，和挖沙船正好相反，河道疏浚，港口碼頭清理都是它的強項，它是由抽沙輸送系統，排空系統，移動系統，船體構成，先把抽砂泵將沙子抽到船艙，載滿后再將船開到岸邊，在把沙輸送到岸邊，該設備操作簡單，工作效率高。它們之間的區別是什么呢？

    首先是操作的區域不一樣，挖沙船適合在沙子多的地方而抽沙船使用范圍廣。適合在湖泊，海河，港口等；輸送距離不同，挖沙船只能輸送近距離的，一般在幾十米左右，抽沙船的距離可達到一千米；下水深度不同，挖沙船距離在30米，抽沙船深度在25米以下；以上是統一重工為您介紹的知識。

The difference between sand-excavating ship and large junk
   Sand-excavating constitute part of the ship has the mining system, the operating parts, gear system, hull, main frame, motivation, such as underwater mining system part, sand-excavating ship diesel engine to start the first, is the clutch, and then launch a diesel engine, and then turn speed is normal, separate sand and sand impurities, through the conveyor belt to transport out, in to the shore. Sand-excavating ship is suitable for the reservoir, river sand separation equipment, diesel engine and electric machine has two sand-excavating ship.
    Pump is suitable for large junk in the sea, lakes, reservoirs and other large area, and sand-excavating ship just the opposite, river dredging, port terminals clean are its strengths, conveying system, it is by the pumping sand drain system, mobile systems, hull, put a sand pump on the sand to the cabin, loaded with again after the boat to the shore, in the sand to the shore, the equipment is simple to operate, high work efficiency. What is the difference between them?
    First is the area of operation is different, sand-excavating ship suitable place in the sand and large junk wide use. Suitable for lakes, the haihe river, port, etc.; Transmission distance is different, can be close, sand-excavating ships generally in dozens of meters, smoked large junk distance can reach a kilometre; In different water depth, sand-excavating ship distance 30 meters, pumping large junk 25 meters in depth; The above is heavy industry to introduce knowledge for you.
