大型的水力選礦設備，如何正確的操作抽沙船是高效率選礦的關(guān)鍵，應如何正確操作抽沙船，有以下幾點：

Large mineral water equipment, how to correct operation suction dredger is key to efficient processing, how to correctly operate pumping sand, there are the following several points:

一、操作說明；首先啟動單缸機，然后啟動四缸機，合上離合器，油門控制在中速以上。扳動卷揚機開關(guān)將龍頭慢慢放下，聽到發(fā)動機有負荷時，停止下放龍頭，然后根據(jù)抽沙濃度來控制龍頭的起落。如果遇到柴油機特別吃力時，應立即將龍頭提起。停機前必須將龍頭升起，直到抽出清水為止。

First, operating instructions; start the single cylinder engine, and then start the four cylinder engine, clutch, throttle control in the medium above. Pulling hoist switch the faucet slowly down, heard the engine load, stop the decentralization of leading, then according to the pumping sand concentration to control the leading the ups and downs. If you encounter a particularly difficult diesel engine, should immediately bring the leading. Before stopping, the cock must rise until it is drawn out.

二、故障排除；如果遇到沙泵抽不出水時，檢查沙泵有無漏氣的地方，檢查各連接處。如果遇到只出水，不出沙時，檢查龍頭吸口有無賭塞或有袋裝物附著物。

Two, troubleshooting; if you encounter sand pump pumping water, check the sand pump there is no leakage of places, check the connection point. If you encounter a water only, not the sand, check whether the head of the suction mouth with a bag or a bag of things.

三、注意事項；嚴禁在抽沙泵正常工作時突然停機，以防沙子堵塞管道。

Three, pay attention to matters; is strictly prohibited in the pumping sand pump normal work when the sudden stop, in case of sand blocking pipe.

四、工作性能；抽沙工作量80立方／小時，抽沙深度水面以下25M。

Four, the performance of the work; pumping capacity of 80 cubic meters / hour, pumping sand depth below the surface of the water 25M.
