Diseño de un banco de pruebas para bombas funcionando como turbinas : Diseño del sistema hidráulico y mecánico.

Abstract

For the present study, the design and modeling of a test bench for pumps operating as turbines is proposed. It was necessary to propose a calculation methodology to be used, which starts with determining suitable values for the head and flow rate of the pump operating as a turbine. In the design, it is considered that its construction is carried out for didactic purposes through experimental correlations to determine head and flow rate values under different operating conditions. This is followed by designing the pipe network according to the ASME B31.3 standard, considering an appropriate fluid velocity, along with calculating major and minor losses in the system. Then, the selection of a pump that meets the flow and head requirements of the pump operating as a turbine was carried out, considering losses in the system. Subsequently, the integrity of the system was verified by analyzing the working pressure and water hammer existing in the test bench. The completion of the calculations and equipment selection allowed for the 3D modeling of the system and the development of blueprints for the test bench. It is concluded that the proposed model has dimensions of 1.34m x 2.07m x 1.89m, with a driving pump of 4HP, project cost of $9116.18, and will generate a power output of 1369 [W].
