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 cleaning effect. Clean gravel from the leaves away, finally into sand trough from the rotation of the impeller, complete sand cleaning effect.
