System and method for detecting and diagnosing pump cavitation

摘要: The present invention provides cavitation detection systems and methods employing a classifier for detecting, diagnosing and/or classifying in pumping system. can be integral to tie system operatively coupled the via controller, diagnostic device computer. Parameters such as flow, pressure motor speed arc measured estimated, then provided Such include Bayesian, Fuzzy Set, nonlinear regression, neural networks other training systems, example signal indicative of existence extent cavitation. An exemplary classification is presented that delineates into one or more following categories: 0 (no cavitation), 1 (incipient 2 (medium 3 (fill cavitation) 4 (surging cavitation). utilized monitoring controlling mitigate pump wear, failure conditions associated with
