The Easy-maintainable Sand Dredger for West European Market meets the operation requirements of inland river sand pumping. It is a self-propelled integral all steel welded sand pumping ship.
Sand pumping principle: firstly, the underwater sand is blown through the high-pressure water gun head on the bridge. The mud and sand blown by the high-pressure water gun form a fluid medium with water under the action of water flow. The mud and sand containing fluid distributed at the suction port of the injection and suction gun head enters the sand pump under the hydrodynamic action of the pump and is transported out through the pipeline.
