A utilização da termografia como técnicas de manutenção preditiva em indústria de fios – estudo de caso

Abstract

Thermography is a technique that allows the measurement of temperatures or observation of differential patterns of heat distribution, by measuring the infrared radiation, naturally emitted by bodies, introducing thermal imaging (thermograms) of components, equipment or processes. It is widely used in mechanical and electrical, as it presents several advantages, such as: low cost; high yield, with the measurement of large areas in a short time; security, because there is no need for physical contact with the equipment. In practice, Thermographic, components involving electricity has the widest application, which inspects heating heating drives, terminals, electrical heating, the control panels to power substations. In electricity and electronics, constant monitoring and early detection of changes in temperature of a finished component enable the prevention machinery failures and consequent loss of productivity, and results in reduced significant in corrective maintenance costs for unwanted failures of machines, because of defects in the electrical components. In this context, the objective of this work is to make a bibliographical survey and present the State of the art use of thermography as predictive maintenance techniques in yarn industry.
