RISA Rotordynamic, Thermal, and Thrust Load Performance Gas Bearing Test Rig and Test Results for Tilting Pad Journal Bearings and Spiral Groove Thrust Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A high-speed gas bearing test rig was developed to characterize rotordynamic, thermal, and thrust load performance of gas bearings being developed for an oil-free turboexpander. The radial bearings (RBs) tested in this ...
Stabilizing a 46 MW Multistage Utility Steam Turbine Using Integral Squeeze Film Bearing Support Dampers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A 46 MW 5500 rpm multistage single casing utility steam turbine experienced strong subsynchronous rotordynamic vibration of the first rotor mode; preventing full load operation of the unit. The root cause of the ...
Experiments on a Large Flexure Pivot Journal Bearing: Summary of Test Results and Comparison With Predictions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flexure pivot® journal bearings (FPJBs) have typically been used in small high-speed applications such as integrally geared compressors and multistage high-speed compressors, where the temperature management and the ...
