Originální abstrakt
Conference article is focused on theoretical and practical deepening of knowledge associated with inlet recirculation in centrifugal pumps, especially with higher specific speed pumps. The conditions of instability of the vortex structures and the causes of recirculation are studied theoretically and experimentally. The methodology is based on the analysis of the Navier-Stokes equations for an incompressible fluid depending on the boundary conditions. The result of the theoretical analysis is the design of various types of dampers in the suction part of the pump, to limit the occurrence of recirculation. Their effect is demonstrated experimentally in laboratory conditions. An article presents individual types of the vortex structures depending on the operating parameters of the pump, including its characteristics. The interest of the research is a plastic model of the pump with specific speed n(q) = 90 rpm which is made by 3D printing technology.
