Critérios para análise de viabilidade para manutenção preditiva em válvulas de controle em indústrias de processo

Abstract

The objective of this work is the definition of criteria for evaluating the feasibility of implementation of predictive maintenance techniques for control valves in process industries. Furthermore, this work brings a view of basic concepts of control valves, and maintenance concept with a focus in these equipments. As from the analysis in the specialized literature, it was possible to get the most frequent failure modes in applications of control valves. These failure modes were confronted with the identifiable failure modes by predictive techniques. In addition to this analysis, it was established classes valve according to their criticality and the possibility for maintenance release. These classes were analyzed according the different maintenance strategies existing, including predictive techniques. The results of these analyzes served as the basis for establishing the criteria, which can help managers of industrial maintenance for evaluating their strategies currently used, as well as to assist in the analysis of technical and economic feasibility for deployment of new applications of predictive techniques.
