Structure of cast components for centrifugal ore pumps. Part 1

With a view to reducing the development time and costs for new flow components of ore pumps, the operation of a Gr pump is simulated by means of FlowVision software. On the basis of the resulting three-dimensional model of the Gr 8 pump and hydrodynamic calculations for the basic pump design, zones of increased flow velocity may be identified. These zones are in good agreement with the zones of increased wear. That confirms the applicability of the model and permits the determination of means of improving the pump geometry (structure).
