RESUMO

The installation, operation and analysis of a rig of test perrnitted to check their particular characteristics, as the use of a Turbina Michell-Banki as motor machine and tests with variable rotation. As a result of this research, we have a demonstration of the viability sustain on the national industry on the improvement of little hydraulic machines, supplying a differentiated experimental support than today it exists in the country, mainly in what says about costs. This work also focuses the definition of the limits of the application of these banks and the study on the variation of the speed during the tests, where this variation, within the recornrnended limits, perrnits the execution of the tests with reduced speed. On the other hand, the turbine and the pump make a group of pumping, whose tests allowed to determine some of their hydraulic characteristics and to infer about it some conclusions. The main characteristics of the group are: the variation of rotation of the pump due the strangulation of the system, and the strong relationship among the variation on the efficiency of the group and the pump. The main conclusion is the evidence ofthe need ofresearches to the optimization of these group... Note: The complete abstract is available with the full electronic digital thesis or dissertations
