The brief introduction to Large Capacity 4inch Underwater Jection Dredger

The Large Capacity 4-inch Underwater Jigging Dredger meets the requirements of the inland river sand pumping operation. It is a self-propelled, integrally welded sand pumping vessel made of all steel.

Sand pumping principle: First, the underwater sand is blown by the bridge's high-pressure water gun. Under the action of water flow, the mud and sand blown by the high-pressure water gun form a fluid medium with the water. Under the hydrodynamic effect of the pump, the mud and sand fluid distributed at the suction port of the gun head enters the sand pump and is transported out through the pipeline.
