Parametrización de una bomba funcionando como turbina: creación del modelo matemático para el análisis de perdidas utilizando python.

Abstract

The following project aims to review the analysis of losses in the use of a pump operated as a turbine and compare the performance curve given by the manufacturer with the one obtained from the consideration of all mechanical and hydraulic losses that may occur. along the pump, for this a SAER NCB 65-200N A brand pump was acquired, from where from its disassembly it was possible to identify the material, its geometry, and other characteristics of each of its parts, where the impeller and the volute stand out and that for the taking of their data it was decided to obtain each of their important measurements by means of molds, after this and analyzing the phenomenon that occurs both at the entrance and at the exit of the fluid, each one of the formulas that make up the losses that occur in each sector of the pump, after that and making a programming code to create a mathematical model that allows obtaining each loss, it was found that there is an increase in height working as a turbine in relation to the height presented in the catalog, after that a high negative incidence was also found in the calculation of the efficiency of the turbine by losses due to leakage , thus showing an efficiency of no more than 56.11% for nominal values, which is notoriously far from the catalog performance.
