| Abstract: | ABSTRACT The pump casing is the most expensive wear component of a centrifugal slurry pump. It determines to a large extent the hydraulic performance of the pump and plays a major role in the overall wear life of the unit. This paper suggests a new approach to compute the mixture velocity and solid particle dynamics in the casing, and on this basis the erosion wear distribution inside the pump casing. Numerical analysis was performed using the finite element method. The model was tested using Georgia Iron Works (GIW) pump casings, at flowrates between 2000 and 4000 US-GPM (US gallons ner minute). The experimental results were obtained in the Hydrualic Laboratory and in field applications in mining and dredging industries. The suggested techniques are useful for estimating casing wear rates and for the optimal design and selection of slurry pumps. |
