Profiled Leading Edge Groove Tilting Pad Journal Bearing For Light Load Operation.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Optimization of a leading edge groove tilting pad journal bearing for application in a small, high speed, multistage steam turbine is described. Rotordynamics constraints to meet a design objective maximum operating speed ...
Root Cause Analysis Of A Long Term Reliability Problem With Reciprocating Compressors In H2 Service.
(Texas A&M University. Turbomachinery Laboratories, 1998)
Three large reciprocating compressors in H2 makeup service had
been a chronic reliability problem for 30 years. Unit revisions
greatly compounded this issue by eliminating builtin spare
capacity. A Root Cause Analysis ...
Squeeze Film Damper Bearing Experimental Vs Analytical Results For Various Damper Configurations.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Higher speeds, longer shafts, and increased power has made squeeze film damper (SFD) bearing performance increasingly more important to control both synchronous and subsynchronous fibration in rotating machinery. SFD bearing ...
Turbine Remanufacture - One Option For Reliability And Efficiency Improvement.
(Texas A&M University. Turbomachinery Laboratories, 1997)
A case study of a remanufacture of a steam turbine is presented. The turbine has been in service for 20 years. Thermal and physical stresses have taken their toll on the turbine casing and supporting hardware. Remanufacture ...
Practical Design Against Torsional Vibration.
(Texas A&M University. Turbomachinery Laboratories, 1996)
One of the foremost concerns facing turbomachinery users today is that of torsional vibration. In contrast to lateral vibration problems, torsional failures are especially heinous since the first symptom of a problem is ...
Design And Application Of Squeeze Film Dampers In Rotating Machinery.
(Texas A&M University. Turbomachinery Laboratories, 1996)
There are common misconceptions and occasional misapplications associated with squeeze film dampers. The authors have worked for more than 25 years researching, experimenting, and applying this subject matter to all types ...
Risk Based Maintenance Of Turbomachinery.
(Texas A&M University. Turbomachinery Laboratories, 1997)
The authors help maintenance staff compete effectively for
scarce corporate resources. Their presentation defines important
concepts, including expected cost of failure ("risk"), avoided
consequential cost, and value ...
Expert Systems Provide Support For A Proactive Machinery Management Methodology.
(Texas A&M University. Turbomachinery Laboratories, 1997)
In today's competitive business environment, one is constantly called upon to make decisions that directly influence operations, and, therefore, profitability. In recent years, it has been necessary to evaluate not just ...
Vibration Monitoring Of Turbomachinery.
(Texas A&M University. Turbomachinery Laboratories, 1990)
