Optimization Study on Pump Series Setting of Deep-Sea Mining Pipeline

Along with the running up of land resources, deep sea exploitation has been important strategic goal of big countries of the world, there are significant meanings to realize efficient and low-energy-consumption piping of deep sea mine. Base on the vertical piping theory of large particles and theory of centrifugal pump, operation points are solved in different working conditions with provided pump series. Consider the problem on the optimization indexes of efficiency, production, power and energy consumption per unit production, conduct analysis and make comparison according to diagrams, optimize the setting of pump series, so as to realize the optimization of pipeline system. The results show that energy consumption per unit production at a higher pump series can be obtained at the minimum, it also ensures higher production and better pump efficiency, this pump series can be selected as the optimal one.
