Induction Motor Vibration Experience
(Texas A&M University. Turbomachinery Laboratories, 2004)
Motor Current Signature Analysis To Detect Faults In Induction Motor Drives - Fundamentals, Data Interpretation, And Industrial Case Histories.
(Texas A&M University. Turbomachinery Laboratories, 2003)
Induction motor drives are the most widely used electrical drive system and typically consume 40 to 50 percent of an industrialized nation’s total generating capacity. In the USA the total generating capacity is approximately ...
Elimination Of Flow-Induced Instability From Steam Turbine Control Valves.
(Texas A&M University. Turbomachinery Laboratories, 2003)
This paper describes two steam turbine governor valve failures in the same installation, the troubleshooting that determined the root cause, and the new valve designed to prevent similar failures. The original governor ...
Development Of Antifouling And Corrosion Resistant Coatings For Petrochemical Compressors.
(Texas A&M University. Turbomachinery Laboratories, 2003)
Two coatings have been developed for petrochemical compressor antifouling and corrosion resistance purposes. One is a multilayer composite coating with a modified polytetrafluoroethylene (PTFE) impregnated organic topcoat, ...
Improved Bearing Alloy - A Contribution Toward Environmental Protection.
(Texas A&M University. Turbomachinery Laboratories, 2003)
There are differences between European and US bearing metals. This paper shows the mechanism for improving the properties of bearing alloys and the environmental problems that have arisen so far in this connection. Since ...
Probabilistic Life Assessment Of An Impeller With Discontinuities.
(Texas A&M University. Turbomachinery Laboratories, 2004)
This paper discusses and presents a probalistic method to evaluate the useful life of an impeller with material imperfections. These discontinuities may be on the surface or subsurface. The method combines linear elastic ...
Low Frequency Instability In A Process Compressor.
(Texas A&M University. Turbomachinery Laboratories, 2004)
A catalytic gas process compressor experienced low frequency vibrations in excess of trip levels following installation of a honeycomb balance piston. After 12 years of operation, low seal oil differential forced an unplanned ...
High Pressure H2 Recycle Compressor Dry Gas Seals Retrofit
(Texas A&M University. Turbomachinery Laboratories, 2004)
Dry gas seal conversions over the last 20 years have progressively become a standard upgrade solution to improving reliability, efficiency, safety and environmental issues related to oil seal technology. The application ...
A Simple Alternative to Keyed Hubs - No More Torches
(Texas A&M University. Turbomachinery Laboratories, 2004)
Application And Operating History Of Moderate-Speed API 618 Reciprocating Compressors.
(Texas A&M University. Turbomachinery Laboratories, 2004)
API Standard 618 (1995), “Reciprocating Compressors for Petroleum, Chemical, and Gas Industry Services,” is written to cover both moderate-speed and low-speed reciprocating compressors for critical service applications but ...
