Repotenciación del banco de pruebas de pérdidas por accesorios del laboratorio de turbomáquinas de la Facultad de Mecánica de la Escuela Superior Politécnica de Chimborazo

Abstract

The objective of this work was to repower the accessory loss test bench present in the turbomachinery laboratory of the Faculty of Mechanics of the Escuela Superior Politécnica de Chimborazo, leaving it functional to carry out the required tests and compare with what was obtained by simulation in the Epanet software. The identification of the problems present in the bank was divided into three sections, those found in the pump, in the tanks, and finally in the accessories board, in that same order, necessary elements were repaired, changed, and implemented to correct the problem operation and facilitate the data collection for the user, optimizing the action times that must be taken when carrying out the laboratory practice. Rigorous tests were carried out to ensure the operation of each of the parts that make up the bank and after that, continue with the data acquisition stage in it. At least five samples of the pressure differentials were taken for each accessory present on the board and from this an average value was obtained that brings us closer to the real value of the differential. Using the Epanet software, the simulation of the test bench was carried out to compare with the results obtained experimentally. It is concluded that the loss bank is optimally functional to carry out laboratory tests, by means of simulation in the software, approximate results are obtained to those found experimentally. It is recommended to implement flow meters for each pipe section and obtain more data for the analysis of the behavior of the accessories theoretically and experimentally.
