The Operating Characteristics Of Gear-Type Couplings
(Texas A&M University. Gas Turbine Laboratories, 1978)
This paper describes in condensed form the results of a research project initiated by the Forschungskuratorium Maschinenbau e. V. and carried out at the Institut fur Maschinenelemente und Konstruktionslehre of Darmstadt ...
Borescope Color Photography: A New Engineering Technology For Marine Gas Turbine Condition Monitoring
(Texas A&M University. Gas Turbine Laboratories, 1975)
This paper discusses the applications of borescope photography for marine gas turbine condition monitoring. A series of borescope photographs are presented showing some of the more common degradation identified in large ...
Design And Full Load Testing Of A High Pressure Centrifugal Natural Gas Injection Compressor
(Texas A&M University. Gas Turbine Laboratories, 1979)
This paper discusses the design of a high pressure reinjection centrifugal compressor. This compressor was tested in the manufacturer’s shop under full load to simulate the field operating conditions in terms of inlet/discharge ...
Design, Performance And Operational Characteristics Of A 6500 Horsepower High Performance Industrial Gas Turbine
(Texas A&M University. Gas Turbine Laboratories, 1979)
This paper will describe the 570-K high performance industrial gas turbine and provide technical rationale for the design approach and performance limits. Construction details are discussed, including assembly of major ...
Fatigue Failures Of Compressor Impellers And Resonance Excitation Testing
(Texas A&M University. Gas Turbine Laboratories, 1979)
The similarity of failures of impellers in centrifugal compressors soon after initial startup and failures of impellers in other compressors after about seven years of successful operation and the test programs to define ...
Centrifugal Compressor Labyrinth Seal Systems
(Texas A&M University. Gas Turbine Laboratories, 1979)
For years, labyrinth shaft-end seals have been used for centrifugal compressors handling air and nonhazardous gases, and for low suction pressure compressors in hydrocarbon service. To prevent gas leakage from the hydrocarbon ...
Practical Considerations For A Rated Speed Shop Balance
(Texas A&M University. Gas Turbine Laboratories, 1978)
The increasing availability of high speed balancing facilities requires the manufacturer and/or ultimate user to seriously consider a rates speed rotor balance. In addition, the development of the "influence coefficient" ...
Particular Problems Of Steam Turbine Lubrication
(Texas A&M University. Gas Turbine Laboratories, 1978)
The reliability of a steam turboset is dependent, among other things, on correct functioning of its hydraulic lubrication and control system. An essential requirement is a reliable oil supply over the whole operating range. ...
Subsynchronous Vibration In A Large Water Flood Pump
(Texas A&M University. Gas Turbine Laboratories, 1978)
In 1973 Aramco embarked on a large water flood projects for the Ghawar oil reservoir. After approximately 1 year in service three of the 16 X 16 X 20 2-stage DVMF pumps developed a severe shaft vibration of over 20 mils ...
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 ...
