A review of machinery diagnostics and prognostics Implemented on a centrifugal pump

Abstract

Centrifugal pumps are a widely used machine found in industries such as water, sewerage, oil and gas. As a result, it is vital that these pumps are monitored, diagnosed, maintained or replaced prior to the pump failing to reduce downtime, material and labour costs. Most companies employ a run-to-fail method or a time based maintenance strategy to service their pumps, instead of condition based maintenance or a predictive maintenance strategy. This paper reviews the state of art in diagnostics and prognostics pertaining to centrifugal pumps. Attention is given to detailing the methods of application, detection of fault modes and results used by researchers in the main areas of diagnostics and prognostics.
