The Prediction Of Bearing Lubricant Temperatures And Cooling Requirements For A Centrifugal Pump
Abstract
A thermal analysis of a centrifugal pump bearing frame using fundamental thermodynamic and heat transfer principles is presented. This analysis enables prediction of bearing lubricant temperatures for a wide range of operating and environmental conditions. An experimental test program run in conjunction with the analytical effort is described. This discussion includes details on the design of a high temperature test facility, the instrumentation and the test procedure. Test measurements are compared to analytical predictions revealing good agreement for several different geometries and operating conditions. Typical results are presented graphically and their practical usefulness explained. The use of a computer program based on this work is also described. This provides a means of quickly establishing the minimum cooling requirements based on the actual pumpage and ambient conditions of a field installation.
