Booster Pump Performance Analysis Towards Rotation Of Impeller For CSD Dredger Type

Abstract

-dredger are a vessel for lift materials from sub surface to another place above the water surface. Dredger divided into some types such Suction Dredger, Bucket Dredger, Backhoe Dredger, and Water Injection Dredger. Cutter Suction Dredger (CSD) is equipped with a rotating cutter head, for cutting and fragmenting hard soils. The soil is sucked up by means of dredge pumps, and discharged through a floating pipeline and pipes on shore, to a deposit area. In some cases, the material is discharged into split hopper barges that are moored alongside the Cutter Suction Dredger. These split hopper barges unload the soil at the deposit area. The most important part of dredger is the pump unit, NPSH is needed to figure the pump performance ability and how the efficiency number of the pump.

Discharging Sediment Downstream: The Opportunities and Challenges of Sediment Management in Sutami Reservoir, Indonesia

“…The output rate is calculated by combining the specified cycle limiting factors, non-dimensional pump features, and slurry transport theory. Calculations are first performed to choose the best booster pump [23], align the pipeline, and establish how much slurry material should be discharged following the dredger specification. Then, the optimum elevation of the downstream outlet is required to determine the total hydraulic head of the dredger instead of the pipe length.…”
