Shaft Riding Brushes To Control Electric Stray Currents.
(Texas A&M University. Turbomachinery Laboratories, 1991)
Electric discharge causing bearing and seal damage may occur in any nonelectric machine as a result of static electricity, accidental electromagnetic self excitation of casings, rotors, piping, foundations, galvanic effects, ...
Rotordynamic Aspects Of A New Hermetically Sealed Pipeline Compressor.
(Texas A&M University. Turbomachinery Laboratories, 1991)
Mopico is an oilfree motor pipeline compressor of fully integrated design with no sealing requirements against atmospheric pressure and supported on magnetic bearings. The application of magnetic bearings for this machine ...
Turbomachinery Balancing Considerations.
(Texas A&M University. Turbomachinery Laboratories, 1991)
The mechanics of balancing, including details concerning tolerances and specifications, tooling, balancing machines, and procedures have been presented many times in the past. However, very little information has been ...
Table of Contents for the Proceedings of the 20th Turbomachinery Symposium
(Texas A&M University. Turbomachinery Laboratories, 1991)
Recent Experience With Large Liquid Injected Rotary Screw Process Gas Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1991)
Advances in manufacturing techniques and design enhancements for such components as shaft seals have made it possible for liquid flooded rotary screw compressors to achieve availability, reliability, and overall performance ...
Adaptation Of A Propylene Refrigeration Compressor With Dry Gas Seals.
(Texas A&M University. Turbomachinery Laboratories, 1991)
The retrofit of a 35000 hp, two-case centrifugal, propylene refrigeration compressor with tandem dry gas seals in DuPont's ethylene plant at Orange, Texas, is described. The installation of these dry gas seals is one of ...
Centrifugal Compressor Performance Enhancement Through The Use Of A Single Stage Development Rig.
(Texas A&M University. Turbomachinery Laboratories, 1991)
Despite recent advances in computation fluid dynamics, the complex flows through centrifugal compressor components are still not totally understood. These uncertainties detract from the designer's ability to accurately ...
Fluid Film Bearing Fundamentals And Failure Analysis.
(Texas A&M University. Turbomachinery Laboratories, 1991)
Fluid film bearing technology is presented in this tutorial as it applies to turbomachinery equipment. The focus here is on the practical aspects of fluid film journal bearings, as opposed to theoretical analysis. Failure ...
Procedure For Selecting And Evaluating A Special Purpose Motor.
(Texas A&M University. Turbomachinery Laboratories, 1991)
During recent years, there has been considerable interest in motors. This interest has stemmed from what appears to be an increase in motor problems. As a result of this, along with the need for machinery reliability, ...
The Investigation Of Suitability Of Abradable Seal Materials For Application In Centrifugal Compressors And Steam Turbines.
(Texas A&M University. Turbomachinery Laboratories, 1991)
Clearances between sealing devices of rotating and stationary components of turbomachinery have always been important to engineers in controlling gas leakages. One way of accomplishing this is by the use of abradable seals ...
