The effect of design parameters of the closed type regenerative pump the energy characteristics

Abstract

The article deals with the application area and features of the regenerative pumps. The main disadvantages of the existing methods for the design of the vortex pump flow part are given. Based on the nature of the flow in the original flow part, calculated according to the classical method, a number of design parameters have been selected and a parametrized 3-D model of a closed type vortex pump has been developed on the base of it, which allows changing parameters together and separately in a wide range. Method for determining the influence of a single constructive parameter on energy characteristics using computational fluid dynamics methods is described in the article. A complex optimization of the flow section of the closed type regenerative pump using the LP-τ search method in the STAR-CCM+ software package was carried out.
