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 ...
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 ...
Development Of Turbomachinery Industry In Japan
(Texas A&M University. Gas Turbine Laboratories, 1977)
This paper deals with the development of the turbomachinery industry in Japan for the past five years. The machinery discussed includes gas turbines, gas expanders, turbochargers, steam turbines, compressors, blowers, and ...
Turbine Rotors Whirl After Dynamically Stable Designs Are Updated
(Texas A&M University. Gas Turbine Laboratories, 1977)
The problem of steam turbine rotor whirling following uprating of a stable design and the measures taken to define the problem and implement a solution are described. Nearly identical units installed at several of Union ...
Repair And Rehabilitation Of Turbomachinery Foundations
(Texas A&M University. Gas Turbine Laboratories, 1977)
The developing of solutions to foundation problems is no longer the frustration it once was. Experience has led to better understanding of problem causes. Technology is evolving to the state that repairs are reliable. ...
