冠誠鉆探抽沙船：
鉆式抽沙船工作原理：抽沙船工作時，電機通過三角帶、減速機、齒輪減速后帶動葉輪緩慢轉動，砂石有給料槽進入洗槽中，在葉輪的帶動下翻滾，并互相研磨，除去覆蓋砂石表面的雜質，同時破壞包覆砂粒的水汽層，以利于脫水；同時加水，形成強大水流，及時將雜質及比重小的異物帶走，并從溢出口洗槽排出，完高效抽沙船成清洗作用。干凈的砂石由葉片帶走，后砂石從旋轉的葉輪倒入出料槽，完成砂石的清洗作用。

Prudential crown drilling sand pumping:

The working principle of drilling pump sand pumping vessel: work, motor through the belt, reducer, gear reducer drives the impeller to rotate slowly, the sand with the feed chute into the washing groove, rolling in the impeller drive, and mutual grinding,remove the gravel covered surface impurities, and destruction of water vapor coated layer of sand, with the at the same time to dehydration; water, forming strong currents, in the small proportion of the impurities and foreign away, and from the overflow outlet washing tank discharge, the efficient pumping sand into the cleaningeffect. Clean gravel from the leaves away, finally into sand trough from the rotation of the impeller, complete sand cleaning effect.
