Atividades de manutenção mecânica preditiva e preventiva nas indústrias do Recôncavo da Bahia

Abstract

This work aims to prospect predictive maintenance activities in the mechanical engineering sector of the Recôncavo da Bahia through a checklist filled in by 31 industries that use mechanical engineering in their activities. To this end, a bibliographic survey of the maintenance concept was initially carried out, followed by research carried out in mechanical engineering companies with more than 07 employees, using data from FIEB (Federation of Industries of the State of Bahia), later a checklist was completed, by the companies. The items considered in the evaluation were limited to preventive and predictive techniques, namely: thickness measurement, vibration analysis, oil analysis, temperature measurement, maintenance plan, sheet ultrasound, balancing, calibration and bearing ultrasound. Based on the results collected, the geographic distribution of companies in different cities of the Recôncavo da Bahia could be represented through the distribution map of predictive maintenance services in the mechanical industry scenario and the results show the presence of predictive maintenance. The companies involved were disaggregated by classes in terms of the number of employees, (55%) of small companies (Class B From 20 to 99 employees), have a higher predictive maintenance rate than Class A (micro companies Up to 19 employees). The companies evaluated were mainly concentrated in Santo Antônio de Jesus (38%) and Cruz das Almas (16%). Future work may increase the number of responding companies, and improve the analysis of results.
