Manutenção preditiva por análise de vibração com utilização de microcontrolador arduino e sensor mems: estudo de caso de um conjunto moto-bomba

Abstract

This work presents the development of a low cost signal acquisition system using Arduino microcontroller (ATmega328) and MEMS Sensor (MPU6050) to measure mechanical vibrations in a motor-pump set at the Monteverde Plant. The diagnosis of the mechanical assembly after spectral analysis and RMS vibration levels according to NBR 10082 and ISO 10816-3. It was identified that the mechanical assembly has severe misalignment as the main defect. An intervention was carried out on the equipment, but even so, the misalignment persists, as it is not possible to perform the alignment of axes properly, due to the structural problem of the base of the equipment. Therefore, it is necessary to program a modification of the motor base in order to allow correct alignment of the set.
