Fatigue Damage Of Steam Turbine Blade Caused By Frequency Shift Due To Solid Buildup - A Case Study.
(Texas A&M University. Turbomachinery Laboratories, 1994)
The case history is presented of a large steam turbine that experienced blade damage after about eight years of service. The probable cause and subsequent solution to the problem are addressed. A discussion of the metallurgical ...
Take Transient Startup And Shutdown Data - Rule Number One.
(Texas A&M University. Turbomachinery Laboratories, 1994)
The thrust herein is to encourage more people to take transient data during startups and rundowns. The common complaint is that it takes too much time and effort to prepare for this information. That argument is "weak" ...
Improving The Mechanical Reliability Of A Turbine-Compressor-Expander Used In A Nitric Acid Manufacturing Plant.
(Texas A&M University. Turbomachinery Laboratories, 1994)
The repair of a turbine-compressor-expander to improve its mechanical reliability is described. The machine is unique, with two open-faced centrifugal compressor impellers in the center, three steam turbine stages overhanging ...
Application Of High Speed And High Performance Fluid Film Bearings In Rotating Machinery.
(Texas A&M University. Turbomachinery Laboratories, 1994)
Some of the critical parameters in the design and application of high performance fluid film bearings are emphasized. The limitations and problems associated with high speed and highly loaded bearings will be discussed. ...
Centrifugal Compressor Application Sizing, Selection, And Modelling.
(Texas A&M University. Turbomachinery Laboratories, 1994)
The objective here is to build on the fan law paper presented at the Twentieth Turbomachinery Symposium [1]. The centrifugal sizing and modelling tutorial draws on the pseudo compressor stage curves presented in the fan ...
Some Thoughts On Avoiding Metallurgical Failures.
(Texas A&M University. Turbomachinery Laboratories, 1994)
Predicting potential problems that will ultimately lead to premature material related failures and implementing the necessary corrections during design, fabrication, and commissioning has long been recognized by some as ...
Recent Experiences In Full Load Full Pressure Shop Testing Of A High Pressure Gas Injection Centrifugal Compressor.
(Texas A&M University. Turbomachinery Laboratories, 1994)
The Use Of Engineering Thermoplastics For Centrifugal Compressor Labyrinths.
(Texas A&M University. Turbomachinery Laboratories, 1994)
The use of engineering thermoplastics is increasing rapidly in today's turbomachinery industry. The primary use of these thermoplastics has been as a material upgrade from aluminum for centrifugal compressor labyrinths. ...
False And Misleading Sources Of Vibration.
(Texas A&M University. Turbomachinery Laboratories, 1994)
Many false sources of "vibration" in rotating machinery of all types are described and discussed. The focus is on the practical distinction between actual vibration and spurious indications of vibration caused by problems ...
Vibrations In Reciprocating Machinery And Piping Systems.
(Texas A&M University. Turbomachinery Laboratories, 1994)
A wide variety of vibration and failure problems occur in reciprocating machinery and piping systems. Excessive piping vibration problems usually occur when a mechanical natural frequency of the piping system or compressor ...
