Hydraulic Modeling of Vane Pump Parameters

Abstract

An analysis of previous studies shows that performance optimization issues in three-dimensional impellers of vane pumps have been insufficiently explored. In a meridional plane, the vanes rotate from an axial to a radial direction in three dimensions. However, the flow studies are primarily limited to those near the impeller inlet and outlet. The goal of these studies is to improve the pump flow path to reduce impeller cavitation wear and improve operating parameters. The data obtained in the study were statistically processed, and based on them, pump design options with optimal parameters can be developed. The article presents key recommendations for studying transient processes using OPV and V-type pump units with an impeller diameter of D_r = 250 mm. The influence of cavitation on the pressure pulsation pattern was determined. Software studies were used to determine the compatibility of impeller modes, which are designed using formulas for high- and low-pressure zones, thereby increasing pump efficiency by 3-5%.
