Mechanical Drive Turbine Control Systems For The 1980's
(Texas A&M University. Gas Turbine Laboratories, 1979)
The changes encountered in moving from mechanical to electrical control of mechanical drive steam turbines are reviewed with regard to both operation and performance. This paper examines past practices in control system ...
Selection And Design Of Tilting Pad And Fixed Lobe Journal Bearings For Optimum Turbo Rotordyanmics
(Texas A&M University. Gas Turbine Laboratories, 1979)
Current trends in bearing designs for turbomachinery are reviewed in terms of manufacturing tolerances and overall design considerations. Discussion of both fixed bore and tilting pad bearings with regard to forced response ...
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 ...
A Review Of The Industrial Development And Usage Of Electronic Governors
(Texas A&M University. Gas Turbine Laboratories, 1979)
The paper presents a review of electronic governors as developed and used by industry. The current interest in the conservation of energy has led many users of prime mover equipment to develop better control technology for ...
Principles Of Turbomachinery Bearings
(Texas A&M University. Gas Turbine Laboratories, 1979)
Self-acting fluid film bearings are the predominant choice for bearings used to position the rotors of high power turbomachinery. The present paper outlines the reasons for their selection, discusses the basic phenomenon ...
Maintenance Techniques For Turbomachinery
(Texas A&M University. Gas Turbine Laboratories, 1979)
This paper covers turbomachinery repair techniques that have evolved from experiences in a large gasoline refinery. Engineering design problems and upgrading of all types of compressors, drivers, and accessories are ...
A New Vibration Criteria For High Speed Large Capacity Turbomachinery
(Texas A&M University. Gas Turbine Laboratories, 1979)
This paper presents the development and analysis of new critical speed criteria. The critical speed has been defined as the resonant speed of the rotor bearing system at which large response amplitudes can occur. However, ...
