Torsional Vibration Of Machine Systems
(Texas A&M University. Gas Turbine Laboratories, 1977)
This paper is concerned with torsional vibration in the design, development, and fault diagnosis and correction of machine systems. The physical behavior of torsional vibrations in shafting systems and sources of torsional ...
High Speed Gears - Design And Application
(Texas A&M University. Gas Turbine Laboratories, 1977)
High speed gear drives can be reliable if all the factors influencing their design, application, and operation are considered during the design stages. This paper will discuss the parameters used by gear engineers and the ...
Mechanical Seal Application - A User's Viewpoint
(Texas A&M University. Gas Turbine Laboratories, 1977)
The purpose of this paper is to present some user guidelines for the selection, operation, and maintenance of mechanical end face seals in chemical, petrochemical, and petroleum operations. Though the exact seal requirements ...
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 ...
Compressor Response To Synchronous Motor Startup
(Texas A&M University. Gas Turbine Laboratories, 1978)
Synchronous machines produce an oscillating torque at twice slip frequency on starting. If the shaft system of a coupled compressor is not adequately designed, or if the motor malfunctions, this torsional excitation will ...
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 ...
