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 ...
The Use Of Honeycomb Seals In Stabilizing Two Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1993)
The stabilizing effects achieved by replacing labyrinth seals with honeycomb seals are described. Although honeycomb seals have been used for some time in high pressure compressors and other turbomachinery applications, ...
Gear Coupling Misalignment Induced Forces And Their Effects On Machinery Vibration.
(Texas A&M University. Turbomachinery Laboratories, 1992)
Gear couplings can produce large static forces and moments that can affect the vibrations of turbomachinery, even with nearly perfect alignment. Research, testing and case histories have verified this theory and are reported. ...
Axial Air Compressors - Maintaining Peak Efficiency.
(Texas A&M University. Turbomachinery Laboratories, 1992)
Axial air compressors have seen increased service in various applications over the years, mainly because of the axial compressor's high operating efficiency, which can be 85 to 90 plus percent. The design of the aerodynamic ...
The Practical Application Of CFD In The Design Of Industrial Centrifugal Impellers.
(Texas A&M University. Turbomachinery Laboratories, 1993)
The practical application of computational fluid dynamics software in the industrial turbomachinery design process is discussed. Such codes have been used for years in the design of gas turbines, but have long been ...
Shifting Critical Speeds Out Of The Operating Range By Changing From Tilting Pad To Sleeve Bearings.
(Texas A&M University. Turbomachinery Laboratories, 1993)
One property of heavily to moderately loaded sleeve bearings is the resulting asymmetric stiffness and damping coefficients. These asymmetric properties often result in split first critical speeds. Since the horizontal ...
Safety, Application, And Service Factors As Applied To Shaft Couplings.
(Texas A&M University. Turbomachinery Laboratories, 1993)
Shaft couplings are rated by their manufacturers as to how much torque they can transmit, how much misalignment they can accommodate, and the maximum speed at which they can operate. Still, manufacturers, buyers, or various ...
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. ...
Improved Reliability Through The Use Of Design Audits.
(Texas A&M University. Turbomachinery Laboratories, 1995)
Rotordynamic design audits of machinery and systems can be used to identify potential problems before manufacture, thus preventing costly project delays and downtime. Machinery engineers need to understand the types of ...
