Diseño e implementación de un banco de pruebas que simule el funcionamiento de un medidor de agua doméstico de la Ciudad de Riobamba y analice la influencia del aire en su desempeño

Abstract

This project aimed to analyze the influence of air on domestic water measuring devices in the city of Riobamba. Thus, the objective of this research was to design and implement a test bench that analyzes the presence of air in pipes and the impact it has on flow consumption measurement. Implementation of the test bench started using the VDI 2221 methodology, where a list of requirements was generated, which tried to solve the functional requirements. Regarding the hydraulic system design, we began by selecting the drive pump. Consequently, select the measuring instruments and hydraulic components, such as the air valve and the air injection system. The domestic water measuring device was provided by the EMAPAR company. A simulation of this phenomenon was carried out in the Flow Simulation section of SolidWorks, validating the hypothesis held. The structure was validated using the SAP2000 software and with rigidity criteria. To validate the prototype, a series of tests were done, varying the operating conditions; without air injection, with air injection, and varying the position of the vent valve. In conclusion, the presence of air in the distribution of potable water measuring devices networks have consequences on the flow measurement, reaching up to a 4.06% increase in water consumption according to the tests carried out.
