IMPROVMENT EFFICIENCY AND CAVTTATION QUALITY CENTRIFUGAL PUMP ON THE BASIS 1 D - 3 D CALCULATE METHOD MPEI

摘要

Necessity of reduction of terms of development high efficiency and modernizations, earlier created but requiring improvements of qualitative parameters blades of systems hydraulic machines, as well as reduction of quantity experimental results in wide use calculate theoretical methods of research hydraulic machines. We shall consider one of approaches of effective designing hydraulic machines. At the first stage in one-dimensional to statement [1] are determined main geometrical parameters of a impeller in meridianal of a projection, as well as situation middle of a surface in the space (fig. 1.). On second, on chosen algorithm, with use of the information of the first stage, space configuration of a blade of initial approximation is formed. On third the analysis and local correction of a geometry blade is executed systems on the basis of given received from the decision direct three-dimensional hydrodynamic of the problem MPEI [2].
