The article describes a new method of automated building parameterized 3D-models of centrifugal pumps. The purpose of modeling is to provide source data for optimization of air-gas channels in type HM pumps by hydrodynamic simulation methods. The first element to be optimised was a volute pump. The algorithm for constructing 3D-models of the discharge device is based on the Bezier curves. Basing on the basic geometrical parameters of the drain, the proposed method allows to automatically create its geometry in the most popular graphics packages SolidWorks and CATIA, and to export the package simulation STAR CCM +.

In this article the tasks, which have to be solved while creating test bench for testing high-power main oil pumps with full speed of rotation, are designated. Feasible ways of introducing energy-efficient technologies to main electrical pump aggregates are defined. The necessity of using frequency regulation of main oil pumps is substantiated. Power supply and regulation systems of pump aggregates, included in test bench, control systems and information collection and analysis systems are shortly described. The general layout diagram of test bench is cited.
