| Abstract: | This paper demonstrates and analyzes the structure of the slurry pump according to the requirements and working characteristics of deep sea mining slurry transportation, focuses on the trafficability of the slurry particles in its prototyping to reduce the possibilitty of the pump being blocked and worn during operation, and reveals the distribution characteristics and flow trajectory of the slurry particles in the pump through the two-phase flow numerical simulation calculation. The results show that the prototype performance meets the design requirements and has stable passability, and provide a basis for the further improvement of the slurry pump. |
