Implementación y automatización de un banco de pruebas para la adquisición de datos de los elementos de protección frente a los transitorios hidráulicos.

Abstract

The current research work is aimed to implement and automate a test bench for acquiring data acquisition of the protection elements against hydraulic transients, minimizing the phenomena of water hammer and cavitation. The purpose of the project is to implement and automate a test bench: this involved the collection of information needed to apply the appropriate methodology in the visualization of results, the study of the existing protection elements in the market and to select the most viable option that meet the user's requirements. Subsequently, the calculation of the maximum pressure in the system was carried out, as well as the selection of hydraulic and automatic elements for the respective test bench, making the selection of the pressure sensor according to the maximum pressure in the pipes. The same principle was used for the selection of other instruments such as: cylinder with diaphragm, relief valve, vent valve and pressure gauge. Lab VIEW software was used to analyze the variable pressure and finally, damping tests of the overpressures caused by the abrupt closure of the valve were performed. The visualization and the damping of the overpressures by means of the protection elements were the results. In conclusion, the test bench for acquiring data acquisition allow us to view the significance of the protection system implementation against pressure overloads, thus improving students' knowledge. It is recommended the proper handling of operation to carry out the process, which will prevent possible breakdowns in the equipment.
