Torsional Vibration Analysis And Testing Of Synchronous Motor-Driven Turbomachinery.
(Texas A&M University. Turbomachinery Laboratories, 2002)
One of the foremost concerns facing turbomachinery users today is that of torsional vibration. In contrast to lateral rotordynamics problems, torsional failures are especially heinous since the first symptom of a problem ...
Subsea Centrifugal Compressor Development - Breakthrough Technology For Oil And Gas Offshore Production.
(Texas A&M University. Turbomachinery Laboratories, 2002)
As the offshore market faces deepwater production challenges, the oil and gas industry is investing in new technologies to bring down the costs in the subsea fields exploitation. A breakthrough technology solution is the ...
New Designs And Applications For Increased Power Recovery And Improved Reliability In FCC Expanders.
(Texas A&M University. Turbomachinery Laboratories, 2002)
Fluid catalytic cracking (FCC) hot gas expanders were developed in the early 1960s and were improved in the early 1980s with updates in airfoil technology. Since then, units designed for pressure ratios of approximately ...
Practical Use Of Rotordynamic Analysis And Troubleshooting Skills To Correct A Long-Term Synchronous Vibration Problem In An Overhung Turboblower.
(Texas A&M University. Turbomachinery Laboratories, 2002)
The two subject blowers operate in parallel to circulate wet chlorine gas. Both units had large synchronous vibrations that led to multiple bearing failures. After simple rotordynamic studies failed to identify the problem, ...
Current And Vibration Monitoring For Fault Diagnosis And Root Cause Analysis Of Induction Motor Drives.
(Texas A&M University. Turbomachinery Laboratories, 2002)
Induction motor drives are the most widely used electrical drive systems and they typically consume 40 percent of an industrialized nation’s total generating capacity. In the USA the total generating capacity is approximately ...
Assessment Of Technology And Economic Benefits Of Reciprocating Machine Condition Monitoring And Diagnostic Systems.
(Texas A&M University. Turbomachinery Laboratories, 2002)
The ongoing trend toward automation of the oil, gas, and chemical industry has significantly changed the entire industry. Digital control systems utilizing advanced computer technologies are installed to manage integrated ...
Rotordynamic Stability Measurement During Full-Load, Full-Pressure Testing Of A 6000 Psi Reinjection Centrifugal Compressor.
(Texas A&M University. Turbomachinery Laboratories, 2002)
Full-load, full-pressure rotordynamic stability measurements were conducted on a seven-stage, back-to-back centrifugal compressor. To validate rotordynamic predictions, the rotor was excited while operating at full load ...
Compressor Discharge Pipe Failure Investigation With A Review Of Surge, Rotating Stall, And Piping Resonance.
(Texas A&M University. Turbomachinery Laboratories, 2002)
Rotating stall, even with multiple cells, can contribute to piping excitation due to acoustic energy traveling down the pipe as a plane wave. The main objective of the paper is to describe causes and solution of fatigue ...
Rotordynamic Tests Of A Flexible Rotor On Flexure Pivot Journal Bearings And Stability Correlation With Frequency Dependent Characteristics.
(Texas A&M University. Turbomachinery Laboratories, 2002)
A series of performance, unbalance response, and stability tests were performed on a flexible rotor incorporating two flexure pivot tilt-pad journal bearings, followed by a theoretical correlations using synchronous and ...
Engineering Fundamentals Of Multi-MW Variable Frequency Drives - How They Work, Basic Types, And Application Considerations.
(Texas A&M University. Turbomachinery Laboratories, 2002)
A brief historical overview of the conversion from mechanical systems to electrical systems at low power levels is presented to gain an understanding of what is occurring at multiple megawatt (MW) power levels in industry. ...
