Abstract

This study deals with the numerical investigation on the shaft behavior of a vertical submersible multistage pump in terms of the axial and radial forces, and the stresses due to the liquid flow through the pump while taking into account different conditions of operation, the gap between the impeller and the diffuser, the rotating speed and the number of stages. This is to improve the pump performances while selecting the bearings and/or the bushes of the submersible pumps in a suitable manner with a long operational life and high reliability. From an existing vertical submersible six-stage pump, a pump model is developed. The continuity, the Navier-Stokes, the stresses and the strains equations are applied to obtain by means of the ANSYS-codes the fields of the liquid flow velocity and the pressure, the stresses, the strains, so as the axial and radial forces. Numerical simulations are carried out to analyze the shaft behavior. The results obtained for the pump head and the stress are validated using the experimental results of the pump head and the results from the classical equations of stresses.
