... ABSTRACT Aiming at the impeller of trailing suction dredger, on the premise of the same impeller dimensions, three kinds of twisted blades with inlet edge shape were designed. The model pump was made according to the proportion of 1:2. The external characteristics and cavitation performance...

... ABSTRACT Cutter suction dredger is one of the ship types widely used in dredging engineering, especially for rock dredging, this ship type has more obvious advantages. Compared with dredging of sediment, rock excavation requires higher performance of cutterhead. Therefore, the determination...

.... The depth increases with the increase of jet pressure, and decreases with the moving speed.The test results provide a theoretical basis for the high-pressure water jet cutting rock breaking system equipped with dredging equipment such as trailing suction dredgers and cutter suction dredgers. INTRODUCTION...
