手机体育投注平台Flow behavior of solid-liquid flow systems depends on the solids’ properties, the carrier fluid and the interactions between the two phases. The solids’ properties of slurry pumping systems such as granulometry and density change as a function of time and location. The above-mentioned changes impact directly the slurry pumping flow rate. In this paper, a dynamic model of an industrial mixing tank with a slurry centrifugal pump is proposed. The dynamic model takes into account the different parts of the pump; the hydraulic part, the induction motor and the system head. A graphical method is then used to estimate the hydraulic part and the induction motor parameters. Regarding the system head, the model is generalized for both homogeneous and heterogeneous flows. The overall model is simulated using MATLAB/Simulink software and validated through a comparison between the results obtained and the real industrial data of a slurry mixing and pumping unit. Finally, the effects of density and level variations on the flow dynamic behavior are studied.
