Effects Of High Pressure Oil Seals On The Rotordynamics Response Of Centrifugal Compressores.
(Texas A&M University. Turbomachinery Laboratories, 1986)
The influence of high pressure bushing-type oil seals on the rotordynamic characteristics of a centrifugal gas compressor, which compresses hydrogen from 1700 psi to 1800 psi is discussed. The compressor rotor is driven ...
Detection of Rotor Cracks
(Texas A&M University. Turbomachinery Laboratories, 1986)
The method of detection of rotor cracks by vibration monitoring is outlined. Various mechanisms stimulating cracks are discussed. Vibration measuring instrumentation and diagnostic methodology for early detection of rotor ...
Retrofit Installation Of A Boiler Feed Pump Hydraulic Coupling.
(Texas A&M University. Turbomachinery Laboratories, 1986)
The application of main turbine-generator shaft drive for boiler feed pumps is generally accepted as a method to increase unit efficiency. The use of shaft drive eliminates the power requirement of an auxiliary motor or ...
