Principles Of Operation And Performance Estimation Of Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1993)
Reverse Alignment - Understanding Centerline Measurement.
(Texas A&M University. Turbomachinery Laboratories, 1992)
Shaft alignment is a key factor in reducing vibrations and increasing reliability in rotating equipment. The most popular method of measurement is "reverse alignment." This method is often considered so complicated that ...
Eliminating Oil Leaks By Optimizing Bearing Case Oil Labryinths.
(Texas A&M University. Turbomachinery Laboratories, 1998)
Many pieces of rotating equipment experience oil leaks. Any
piece of equipment with oil fed bearings, such as turbines, motors,
gearboxes, and compressors, are susceptible to oil leaks from the
bearing case seals. Usually ...
Dry Gas Seal Retrofit.
(Texas A&M University. Turbomachinery Laboratories, 1995)
Conventionally lubricated shaft sealing systems have long been known to be unreliable, high in maintenance and in some cases hazardous in centrifugal compressors. Labyrinth sealing systems, while generally low in maintenance, ...
Development And Field Application Of A Single Rotor Design Dry Gas Seal.
(Texas A&M University. Turbomachinery Laboratories, 1995)
Improving centrifugal compressor seal performance and reliability can be accomplished through development of new technology and/or by improvement of existing technology. An improved dry gas lubricating seal of single rotor ...
Experiences In Analysis And Monitoring Compressor Performance.
(Texas A&M University. Turbomachinery Laboratories, 1995)
Evaluations of life cycle costs in typical turbomachinery installations have shown that for reliable machines, energy costs normally far outweigh purchase, installation, and maintenance costs. Experience has shown that ...
Improvement Of Centrifugal Compressor Reliability Handling High Pressure And High Density Gas.
(Texas A&M University. Turbomachinery Laboratories, 1999)
Centrifugal compressors handling high pressure and high density
gas can sometimes encounter trouble such as rotor instability and
impeller resonance vibration while in operation. In order to eliminate
these problems, ...
An Application Of A Hydrostatic Pressure Lift System For Control Of Variable Thrust Loads.
(Texas A&M University. Turbomachinery Laboratories, 1995)
Thrust bearing failures on older equipment, especially large steam turbines, can be costly problems to remedy. A unique solution to a steam turbine thrust bearing problem that confronted Southern California Edison (SCE) ...
Annular Gas Seals And Rotordynamics Of Compressors And Turbines.
(Texas A&M University. Turbomachinery Laboratories, 1997)
The possible negative or positive impact of annular seal on
rotordynamics of compressors and steam turbines is discussed. The
nature of destabilizing forces that can be developed by "seethrough"
and interlocking labyrinths ...
Dry Screw Compressors In Process Gas Applications Including Maintenance Considerations.
(Texas A&M University. Turbomachinery Laboratories, 1992)
The dry screw compressor, which combines the advantages of positive displacement with rotary motion, is gaining wider international acceptance for process gas applications. The selection of dry screw compressors is dependent ...
