An Operation History Of Fractional Frequency Whirl
(Texas A&M University. Gas Turbine Laboratories, 1975)
The problem of a whirling rotor in a high pressure centrifugal compressor and the steps to arrive at a solution are described. Orbit shapes and vibratory motion are illustrated. Vibratory frequency ratios compared to ...
Less Costly Turboequipment Uprates Through Optimized Coupling Selection
(Texas A&M University. Gas Turbine Laboratories, 1975)
Compressor and driver shafts often prove to be overstressed in equipment uprate situations. This paper shows how a change from conventional gear-type couplings to the more recent diaphragm coupling design can lower the ...
Examination Of Pump Cavitation, Gear Mesh And Blade Performance Using External Vibration Characteristics
(Texas A&M University. Gas Turbine Laboratories, 1975)
Whereas the interpretation of the low frequency vibration characteristics generated by operating machinery is relatively well understood, the use of the high frequencies, sonic and above, to predict conditions such as blade ...
Plain Bearing Damage
(Texas A&M University. Gas Turbine Laboratories, 1975)
Correct diagnosis is the first step towards improved reliability. The paper investigates in some detail, cases of bearing damage in turbomachinery, for plain cylindrical and tilting pad journal and thrust bearings. Types ...
Table of Contents for the Proceedings of the 4th Turbomachinery Symposium
(Texas A&M University. Gas Turbine Laboratories, 1975)
Design And Development Of A New 30,000 Hp Class Two Shaft Type Gas Turbine
(Texas A&M University. Gas Turbine Laboratories, 1975)
A description of the application of advanced technology, high temperature, gas turbine design technique to a new model two-shaft type gas turbine to achieve a high efficiency, high reliability, regen cycle and simple cycle ...
Gas Turbine Operation In Extreme Cold Climate
(Texas A&M University. Gas Turbine Laboratories, 1975)
The effects of extreme cold weather on gas turbine operation are described. Suggestions are made which will enhance overall operational effectiveness. The comments and specific recommendations are based on Solar’s experience ...
