Vibration And Eccentricity Measurements Combined With Rotordynamic Analyses On A Six Bearing Turbine Generator.
(Texas A&M University. Turbomachinery Laboratories, 1998)
This lecture discusses how the vibration characteristics and
eccentricity measurements were combined with rotordynamic
analyses to help improve the reliability of a turbine generator unit.
It also explains certain ...
Design Modifications And Active Balancing On An Integrally Forged Steam Turbine Rotor To Solve Serious Reliability Problems.
(Texas A&M University. Turbomachinery Laboratories, 1998)
This paper describes the design modifications and active
balancing on a 19,000 hp integrally forged steam turbine rotor to
improve its dynamic characteristics and reliability. The turbine was
purchased as a replacement ...
Starter Motor Sizing For Large Gas Turbine (Single-Shaft) Driven LNG Strings.
(Texas A&M University. Turbomachinery Laboratories, 1998)
The purpose of this paper is to describe how computer
simulation was used to size the main starter motors for single shaft
gas turbine driven compressor strings used in a large LNG plant.
The paper describes how the ...
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 ...
