Impeller balance hole
Witrynaof the impeller, wear ring, and balancing holes on the axial thrust. The results showed that the wear ring and balancing holes influenced the axial thrust, but the back gap of the impeller did not have a significant influence on the axial thrust. Lefor et al. [2] compared the casing ribs and J-grooves used to Witrynaand closed impeller were investigated by using the Computational Fluid Dynamics (CFD) method. In this context, the flow rate and the some physical properties such as the back gap of the impeller, wear ring and balancing holes, of the centrifugal pump were investigated to determine how much affected the axial load.
