MODELING AND CALCULATION OF STRUCTURES OF CAST PARTS OF CENTRIFUGAL GRAVEL AND GROUNDWATER PUMPS TO OPTIMIZE THEIR GEOMETRY AND THE DEVELOPMENT OF NEW CHEMICAL COMPOSITION OF THE ALLOY. PART 1

In order to explore the possibilities of time and cost reduction of developing and perfecting new ore flow parts of pumps was used mathematical modeling of the “Gr” series pump with the software package “FlowVision”. A three-dimensional model of “8 Gr” series pump and the calculations of hydrodynamics working fluid pump base design allowed authors to estimate the zone of elevated flow rates . It was found that the calculated areas are well coincided with areas of high wear , which confirmed the adequacy of the model and allowed to determine the direction of improving the geometry (structure) of the pump.
