T05: Methods to Effectively Evaluate Modern Journal Bearing Performance and Achieve High Reliability
Abstract
Centrifugal compressors and steam turbines commonly use hydrodynamic journal bearings These bearings can be fixed geometry(sleeve) or tilting pad type Most end users expect bearings to operate trouble free from major turnaround to major turnaroundCompressor manufactures continue to push the design limits of their equipment, reduce costs and optimize machine performanceHowever, this can increase the risk of bearing issues in new machines and in operating machines as they age As discussed in thistutorial, industry standards offer limited guidance on how to design or apply hydrodynamic bearings to prevent wear or damage So,how can end users evaluate bearing design performance to achieve high reliability? The objective of this tutorial is to answer thisquestion
