Identificação dos mecanismos de danos atuantes em bombas centrifugas magnéticas através da análise de falha

Abstract

In the chemical and petrochemical industry, the use of magnetic centrifugal pumps are practically predominant for the transfer of liquid fluids considered clean and dangerous. Therefore, it is extremely important to know the damage mechanisms, root cause of failures and generate more efficient maintenance plans. effective for these devices. In this article, through a actual study, existing damage mechanisms, failure modes and plan of action maintenance created from a Failure Modes and Effects Analysis - FMEA. The actions adopted from preventive plans seek to reduce unexpected failures, reduction in operating and maintenance costs, as the equipment presents greater monitoring and/or follow-up during its operating life.
