Parametric analysis of deep sea mining transportation system

According to the requirement on hydraulic transportation equipment in the flexible pipe mining system, the hydraulic transportation equipment with combined conveyance of material storage tank and high-pressure pump was developed, thus made a break-through on the key techniques of flexible pipe mining system. On the basis of two-phased flow theory, the designing theory of the hydraulic conveyance equipment with combined conveyance of material storage tank and high-pressure pump was established, and provided theoretical basis for the design of this kind of hydraulic conveyance equipment. In the light of the above stated designing theory, analysis and research were carried out upon the parameters of medium trial system of 1000m cobalt incrustations mining and of 3000m cobalt incrustation mining system. The demonstration was carried out on the feasibility of the hydraulic conveyance equipment with combined conveyance of material storage tank and high-pressure pump.
