Abstract:The lift system, acting as the passage for the transportation of the seabed ore, is the intermediate part between the seabed mining vehicles and surface mining vessels. This paper focused on the key technologies and equipment for the slurry pump hydraulic lifting system, a flow model and theory for lift coarse particle slurry were put forward. It is proposed that slurry pump is a kind of mixed flow pump with high specific speed, which can pass the coarse particles with high lift head and with axial flow and backflow. The theories for increasing the flow rate design, as well as the equal power design for it were also elaborated, which were all tested with slurry in the laboratory and also verified in the sea-test for pumping seabed mineral slurry. These theories and technologies have been applied to improve slurry pump lifting system for commercial mining of seabed mineral resources.
Key words: marine mineral resources; hydraulic lift system; coarse particle slurry; slurry pump
