Projeto e montagem de um protótipo para estudos de bombas centrífugas e controle de processos industriais.

Abstract

The industrial market has shown constant improvement in the development of new technologies and tools. To keep up with the demand for specialized labor, educational institutions invest in various teaching tools that help in the training of professionals in the area. Didactic benches have proved to be a great resource to add to the technical knowledge of real work operations. In addition to being more accessible than the work environment itself, they are highly versatile in terms of use, with customized assembly according to training needs. Bearing in mind the importance of training future professionals in the industry, in this work a didactic workbench was designed and built capable of enabling the practical study of pumping systems, aiming at low cost and accessibility for students. The experimental unit offers the user a set of elements that were installed aiming at carrying out experiments in different areas of engineering, such as transport phenomena, unit operations, control systems, among others. The prototype has a platform with microcontroller that allows the experimental survey of the pump curve, in addition to a graphic interface (supervisory) that monitors the main process variables, which in this work were: level of the liquid discharge reservoir and pressure at the pump outlet. Considering the study of the association of centrifugal pumps, experiments were carried out to compare the experimental and theoretical operating point of the system. The results obtained show a deviation of 26.75% for operation with only one pump, 21.70% for two pumps in series and 23.90% for two pumps in parallel.
