深海采矿高扬程粗颗粒多级输送电泵研究
Research on multistage lifting motor pump of high lift and coarse particles in deep sea mining
摘要
Abstract
Aiming at the problem of high head, coarse particle over current and axial flow in lifting motor pump, the whole design of multistage pump for deep sea mining was selected as research object. By contrasting the excellent model of deep sea mining pump at home and abroad, a design method of multistage pump for high lift and coarse particle was proposed, and the design of four stage lifting motor pump in deep sea mining was completed. The external load, axial force and bolts bear tensile force of multistage pump were analyzed and calculated, and the strength and rigidity for multistage pump body were calculated by using the finite element analysis software. Finally, the operating characteristics for two stage lifting pump were tested. The result shows that when the designed flow rate is 432 m3/h, the head of the two stage pump is 82 m. When the concentration of the slurry is from 0 to 10%, the pump power-flow curve is mild. All parts of the pump meet the requirements for strength and rigidity, which verifies the validity of the design method of multistage pump.关键词
