This work is devoted to the design problems of axial flow pumps intended for pumping lead coolant associated with the physical and physicochemical characteristics of this coolant in comparison with traditional ones, such as water and sodium. Calculation methods used in the design of pumps require modifications and a large array of experimental data that will justify the applied technical solutions and adapt traditional calculation methods. One of the problems is the lack of the ability to analytically assess the effect on the operation of the system of such a factor as the non-wettability of the surfaces of structural materials with lead, which does not allow, using existing modeling methods, to adequately obtain a picture of the movement of lead in the interscapular channels. In connection with this in the laboratory “Reactor hydrodynamics” NSTU n.a. R.E. Alekseev, experimental studies of the dependence of the characteristics of axial pumps for pumping lead coolant on the geometric characteristics of the main elements of the flow path of the pump, affecting the energy characteristics of pumping equipment were carried out. The results of the following experimental studies are presented: 1) the parameters of the straightening devices installed at the outlet and inlet of the flow to the impellers, 2) swirling of the flow at the inlet to the impeller relative to the direction of rotation of the pump impeller, 3) the parameters of the impeller profile lattice, 4) changes in the angle attacks relative to the angle of installation of the profile lattice vane, 5) the geometry of the outlet section of the impeller profile lattice vanes, 6) the bushing ratio of the impeller. The obtained array of experimental data can be recommended for use to amend the existing design techniques for pumps for pumping heavy liquid metal coolant.
