Abstract

The article covers a review and analysis of centrifugal (vane) pumps produced and manufactured in our country and abroad. Among the variety of requirements for the design of pumps, the fundamental ones were identified, which directly affect the course of the technological process as a whole. Based on the analysis and review, a method for determining the design parameters of the pump has been developed and described. In this case, the described technique can be used when developing mixers using a centrifugal (blade) wheel. Using the described methodology, an impeller was developed and the technological process of its operation was described. In the course of theoretical calculations, a regression equation was obtained to determine the pressure at different speeds of the impeller shaft, taking into account the corresponding resistances, depending on the feed. Experimental and theoretical studies have confirmed the design of the developed wheel for a mixing plant based on a vane pump. At the same time, the nominal values of indicators such as flow, pressure, efficiency and useful power were obtained for various operating options of the installation. Thus, the installation showed its operating efficiency as for a conventional pump, which can move liquid and mixtures.
