User Insights For The Effective Purchase Of New Turbomachinery.
(Texas A&M University. Turbomachinery Laboratories, 1995)
As organizations reengineer to become more competitive and as people are exposed to the purchase of new machinery in an increasingly competitive international market, an acquaintance with the activities needed for effective ...
Leakage And Rotordynamic Effects Of Compressible Annular Seals.
(Texas A&M University. Turbomachinery Laboratories, 1995)
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 ...
Large Converter-Fed Adjustable Speed AC Drives For Turbomachines.
(Texas A&M University. Turbomachinery Laboratories, 1992)
Converter-fed adjustable speed electric motors are now finding increasing use for driving turbomachinery in the power range from 1.0 to 20 (50) MW. The most important properties of these drives are explained, with the main ...
A Flexible Pad Bearing System For A High Speed Centrifugal Compressor
(Texas A&M University. Turbomachinery Laboratories, 1992)
The application of a new radial and thrust bearing for use in high speed integrally geared centrifugal compressors is presented. The bearing design is of the flexible pad type. Bearing design analyses were conducted to ...
Troubleshooting Turbomachinery Problems Using A Statistical Analysis Of Failure Data.
(Texas A&M University. Turbomachinery Laboratories, 1990)
The use of statistical techniques to investigate machinery failure data is one of the most powerful troubleshooting tools available to the turbomachinery engineer. This analysis tool can provide a great deal of information ...
Retrofit, Upgrade, And Demothball Of Two Crentrifugal Compressor Trains.
(Texas A&M University. Turbomachinery Laboratories, 1990)
The design premise in upgrading two operating plants for more compression capability is discussed.
The first is a syn gas plant designed for 1000 tons/day of methanol but converted to syn gas only for a primary acetic ...
Understanding The Vibration Forces In Induction Motors.
(Texas A&M University. Turbomachinery Laboratories, 1990)
Squirrel cage induction motors have been used extensively in industry for over 50 years. While it appears that vibration problems are more pronounced nowadays, certain basic construction features have always existed and ...
Magnetic Bearings And Dry Gas Seals - A Process Compressor Application.
(Texas A&M University. Turbomachinery Laboratories, 1990)
The design considerations and features along with manufacturing and operating experiences encountered on a multistage centrifugal process compressor incorporating a dry gas seal and active magnetic bearings immersed in the ...
Influence Of Oil Injection Method On Thrust Bearing Performance At Low Flow Conditions.
(Texas A&M University. Turbomachinery Laboratories, 1999)
The advantage of operating a thrust bearing in an evacuated cavity has been well documented in the literature. By draining the
oil from the bottom of the housing and eliminating standing oil around the thrust collar, ...
