Abstract

A vertical submersible two-stage pump is investigated in terms of the axial and the radial forces on its shaft due to the liquid flow through the pump while accounting for the different flow rates. Also, a preliminary experimental test bench is performed to achieve the strains and the stresses on a pump shaft supporting an impeller as a function of the rotating speed. In fact, from an existing vertical submersible two-stage pump, a pump model is developed. The continuity and the Navier-Stokes equations are applied to obtain by means of the ANSYS-codes the fields of the liquid flow velocity and the pressure, as well as the axial and the radial forces acting on the pump shaft. The numerical results obtained for the pump head are validated using the experimental results. Three available axial forces for three flow rates from industry are used for the comparison with the numerical axial forces. The achieved experimental results from the preliminary test bench reveal that the strains and the stresses on the pump shaft increase with the raising of the rotating speed.
