MANUTENÇÃO DE BOMBAS HIDRÁULICAS CENTRIFUGAS: como deve ser um plano de manutenção de uma bomba centrífuga, para evitar a ocorrência de falhas como aquecimento, quebra e desalinhamento.

Abstract

This work aims to carry out analyzes of a multi-stage centrifugal pump, analyzing its main problems and causes of premature breakage of parts. We will also learn about some types of pumps present on the market from the past to the present day. The study aims to evaluate the pump and using ISO 5199 and NBR 5462 (regulatory standard), present components of hydraulic pumps, point out differences in the equipment, address concepts of fluid mechanics, aspects of corrective, preventive, predictive maintenance. The purpose is to explore the main failures of a centrifugal pump, collecting data and monitoring its operation in order to highlight a study of a Maintenance plan in order to analyze which of the three types of maintenance is suitable for the study. The results concluded were not satisfactory as we were unable to generate a (preventive) maintenance plan for the chosen centrifugal pump, but we had great success in evaluating the main causes of pump failures. The equipment was exchanged for a new pump and we defined a preventive maintenance plan so that the equipment can last longer.
