Implementação de técnicas de manutenção preditiva num exaustor de cabine de pintura

Abstract

There is an indispensable premise for all factories that aim to remain competitive in the globalized market of the 21st century: avoiding unscheduled machine downtime, especially those that are highly critical in the production process. This work aims to implement predictive maintenance techniques in a paint booth exhaust, a fundamental process in a semi-trailer company. A specialized system capable of automatically interpreting data from vibration spectra and providing fault diagnosis was implemented. As a result, collections carried out at high periodicity allowed significant progress towards predictive maintenance. After installation, tests and procedures were carried out to understand the main causes of mechanical vibrations in the system. From the vibration spectra provided by the sensors, it was observed that the mass non-uniformity in the rotor is the main reason for unbalance in the system and, consequently, a major cause of mechanical vibrations.
