 The paper describes the choice of main criteria for assessing the quality of building a drainage pump NM10000-210. The aim of selection of the main criteria is correct assessment of optimization of building drainage through simulation program STAR CCM +. According to simulation results values ​​of evaluation criteria for 20 sample points were obtained. Further, after analyzing the simulation results and geometric parameters the authors defined ranges of changed geometrical parameters for which the quality criteria of profiling have the lowest / highest values. They suggest choosing the settings jointly by two criteria of quality assessment, while the determining criterion is minimization of friction losses.

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.
