Diagnóstico de falha em bomba centrífuga na indústria petroquímica

Abstract

Centrifugal pumps play an important role in the transfer of fluids in industrial processes. According to Lima (2003) the centrifugal pump is a machine that supplies energy to the liquid through centrifugal force to the fluid flow. The use of this machine is increasing day by day, from way that makes the operation more flexible in the industrial areas. In addition to providing large flows and moderate pressures, the low maintenance cost is a factor fundamental for the use of this type of pumps in the industries. So this The objective of this work is to carry out the diagnosis of failure in the solution of problems of a centrifugal pump used in an industrial plant. The work shows the study case in a reflux pump, responsible for removing styrene and heavy, with a history of consecutive failures in the sealing system. After several interventions were carried out to correct and maintenance intervention in order to resolve the fault. In the study performed, it can be considered that the increase in reliability of the equipment, because to date there has been no recurrence of the occurrence of failure. After the implementation of the inspection route, the effectiveness of improvement actions implemented in the company's industrial plant. The solution presented was replicated for the other rotating equipment in the unit of industrial plant.
