TIPOS DE PROBLEMAS EM BOMBAS HIDRÁULICAS CENTRIF

Abstract

This work has the proposal of a case study to point out the causes of locks of bearings of a Centrifugal pump and a study and its main defects, to maximize the operation in the face of the application of correct techniques and methods used in the maintenance of a Centrifugal pump and a study how a centrifugal pump should be, to avoid the occurrence of failures such as heating, breakage and misalignment for this equipment performing analyzes of a multi-stage centrifugal pump, analyzing its main problems and causes of prematurely breaking parts. We will also learn 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 hydraulic pump components, point out differences in equipment, address concepts of fluid mechanics, aspects of corrective, preventive, predictive maintenance. For the development of this work is based on bibliographic research linked to the techniques, analysis and practical application tools used to carry out the study. The purpose is to explore the main failures of a centrifugal pump by collecting data and monitoring the operation in order to show a study of the main defects. We conclude that the Schneider model was a total loss, due to its use for more than 10 years of work provided without maintenance, we were unable to recover the analyzed model. However, we were able to show the main problem that causes Schneider pump.
