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 ...
Preface for the Proceedings of the 32nd Turbomachinery Symposium
(Texas A&M University. Turbomachinery Laboratories, 2003)
Compressor Seal Selection And Justification.
(Texas A&M University. Turbomachinery Laboratories, 2003)
The sealing of rotating equipment has always presented a special challenge for rotating equipment manufacturers and end users. Shaft seals are provided to restrict or prevent the escape of process or sealing fluids to ...
Turbine Overspeed Trip Protection.
(Texas A&M University. Turbomachinery Laboratories, 2003)
This paper discusses the design, history, current standards and designs, and the relation between turbine overspeed and the time constant of rotors. Overspeeding of turbine rotors as it pertains to time lag of the overspeed ...
Online Technique To Mitigate The Risks That Limit Expander Reliability.
(Texas A&M University. Turbomachinery Laboratories, 2003)
Expander reliability has been limited by flow path erosion, corrosion, and deposition. Through root cause determination of the failures and laboratory testing, advances in machine designs and online monitoring and cleaning ...
