Revamping A Gas Compressor Drive Train From 7000 To 8000 HP With A New Synchronous Motor Driver And A Controlled Slip Clutch Mechanism.
(Texas A&M University. Turbomachinery Laboratories, 2006)
The successful application of synchronous motors requires special design consideration to account for their speed-dependent characteristics, such as the large oscillating torque levels that occur during startup. This paper ...
Materials Issues For Users Of Gas Turbines.
(Texas A&M University. Turbomachinery Laboratories, 2006)
Material issues are of paramount importance for the reliable and cost effective operation of gas turbine engines. Because of the high turbine temperatures, the materials degrade over time, which requires their repair or ...
Gas Turbine Tutorial - Maintenance And Operating Practices Effects On Degradation And Life.
(Texas A&M University. Turbomachinery Laboratories, 2007)
Proper maintenance and operating practices can significantly affect the level of performance degradation and thus time between repairs or overhauls of a gas turbine. Proactive condition monitoring will allow the gas turbine ...
A Practical Guideline For A Successful Root Cause Failure Analysis.
(Texas A&M University. Turbomachinery Laboratories, 2007)
Root cause failure analysis is a process for identifying the true root cause of a particular failure and using that information to set a course for corrective/preventive action. From a technical standpoint, it is usually ...
Refining Fundamentals (Unpublished).
(Texas A&M University. Turbomachinery Laboratories, 2007)
Bearing Issues with a Flooded Screw Compressor
(Texas A&M University. Turbomachinery Laboratories, 2008)
Startup of Parallel Turbo Expander-Compressor Units Operating in Hydrocarbon Processing Plants
(Texas A&M University. Turbomachinery Laboratories, 2008)
Torsional Oscillation Trouble on VFD Motor Driven Recip Compressor
(Texas A&M University. Turbomachinery Laboratories, 2008)
High vibration problems including failed coupling parts on a VFD motor driven reciprocating compressor are analyzed and the root causes and solutions are discussed in this costly field issue.
Development and Implementation of VFD Active Damping to Smooth Torsional Vibrations on a Geared Train
(Texas A&M University. Turbomachinery Laboratories, 2008)
Journal Bearing Vibration and SSV Hash
(Texas A&M University. Turbomachinery Laboratories, 2008)
Peculiar, low-frequency, radial vibrations have been observed in various turbomachinery using tilt-pad journal bearings. Unlike discrete subsynchronous spikes that often indicate a serious problem, the vibrations are ...
