Condition Monitoring Of Rolling Element Bearings Installed In Centrifugal Pumps
Abstract
Monitoring the condition of bearings in centrifugal pumps continues to be an important concern to pump users, especially in critical pump installations. Additionally, pump users are interested in simple, easy to use, moderate cost, reliable bearing condition instruments. Bearing condition monitoring methods, such as vibration analysis, shock pulse, and bearing outer race deflection have proven successful in laboratory tests, but direct comparisons have often been lacking. The results of tests conducted on an ANSI Type 1.5x3-8 centrifugal process pump using these bearing condition monitoring methods are presented. Installation and operational considerations which need to be addressed when using the various bearing condition monitoring methods on centrifugal pumps are discussed. It is considered noteworthy that the system that monitor bearing outer race deflection had the greatest success in detecting bearing defects while the traditional case mounted velocity transducer system was the least successful in detecting the same bearing faults.
