The cutter suction dredge consists of a large barge shape vessel that normally doesn’t have propulsion equipment and is mobilized to the job site by other vessels. It has centrifugal pump. on board that are used to pump slurry (mixture of solids and water) to a disposal location. The dredge has a ladder that supports the cutter and cutter drive unit and the suction line leading to the suction side of the dredge pump. At the end of the suction line and cutter drive shaft is the cutter head that is used to loosen and cut sediment that must be removed from the bottom of the waterway. The cutter may have special teeth for excavating the bottom. The excavated material is mixed with the surrounding water and drawn up the suction pipeline due to the low pressure created by the pump on the suction side. The dredged material may consist of clay, silts, sands and gravel and the slurry may be as much as 20% sediments by volume and the other 80% is the ambient fluid. In some cases, an additional pump may be located on the ladder when dredging depth is deep in order improve production due to cavitation limitations.
PURPOSE: The cutter suction dredger is mainly used for dredging harbor, river channel, lake or lagoon or pond, or dredging sand for building.
Working conditions: Max. Temperature40℃ ; Min. Temperature -10℃; Max. Water Temperature32℃; Relative Humidity less than 70%.
First the hydraulic cutter in the ladder cuts sediment below water, and makes it loosen then dredged sand moved by the rotated cutter mixes with water and form liquid medium.Then the sand liquid in the inner cutter blade and beside the marine pump suction functioned by the fluid power of sand pump, enters sand pump, meanwhile, get some energy, at last, it is discharged to the destination through discharge pipe.
