Magnetic Bearing Operating Experience.
(Texas A&M University. Turbomachinery Laboratories, 1994)
Over the past 10 years, magnetic bearings have been making significant changes to the rotating equipment industry. As magnetic bearing systems become more accepted and the numbers of applications increase, so do the operating ...
The Baffling And Temperature Prediction Of Coupling Enclosures.
(Texas A&M University. Turbomachinery Laboratories, 1994)
Increasingly, turbomachinery users are setting upper limits on coupling enclosure temperatures. This is done either to protect personnel, to ensure the proper operating temperature for bearing oil that leaks past seals (or ...
Tilting Pad Bearing Design.
(Texas A&M University. Turbomachinery Laboratories, 1994)
The basics of tilting pad bearing design are discussed to include limits of operation for load, speed, and metal temperature. Optimum temperature sensor locations are recommended for self-aligning and nonaligning tilting ...
General Purpose vs. Special Purpose Couplings.
(Texas A&M University. Turbomachinery Laboratories, 1994)
Flexible couplings are a vital part of a power transmission system. What type is selected, how much the coupling costs, and how much effort one spends on selecting a coupling and determining how it interacts with a system ...
Process Safety Management.
(Texas A&M University. Turbomachinery Laboratories, 1994)
Impeller Repair Techniques For Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1994)
Successfully repairing centrifugal compressor impellers requires careful consideration and planning. The selection of techniques for inspection, material, and welding procedures are determined by numerous factors. Original ...
Selection Of Turbomachinery - Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1994)
One of the primary functions of the rotating machinery engineer is the application and selection of turbomachinery. During the early stages of a project, the process engineer needs to know the performance of turbomachinery, ...
Retuning A Gear Disc Profile To Eliminate High Gear Vibration.
(Texas A&M University. Turbomachinery Laboratories, 1994)
High gear case acceleration levels, experienced during shop string testing of a compressor train, were traced to gear element structural resonance, which was excited by the gear tooth meshing frequency. Finite element ...
Lubrication And Seal Oil Systems - Common Problems And Practical Solutions.
(Texas A&M University. Turbomachinery Laboratories, 1993)
Current technologies now make it possible to build turbomachinery without the need for a lubrication and seal oil system. However, there is an established machinery population that still requires support systems for oil ...
Reduced Shaft Stiffness Lowers Running-Speed Bearing Loads And Vibration In A Single Stage Compressor.
(Texas A&M University. Turbomachinery Laboratories, 1993)
Turbomachines that run well above their fundamental lateral critical speeds (super-resonant), and are not heavily influenced by higher vibrational modes, can often benefit from reductions in shaft stiffness to lower the ...
