Assessment of the level of influence of various geometrical parameters of the centrifugal pump guide vane on its energy characteristics

Abstract

Abstract The article is devoted to the research of the influence of geometrical parameters of the inlet section of the multistage pump radial channel guide device on its hydraulic efficiency. The obtained values of hydraulic efficiency, considered depending on the geometrical parameters of the guide device, are given. The efficiency parameters were obtained via hydrodynamic modeling. Recommendations on the optimal geometric parameters are offered and compared with already known semi-empirical formulas.
