A Discussion Of Turbine And Compressor Sealing Devices And Systems
(Texas A&M University. Gas Turbine Laboratories, 1977)
This discussion briefly summarizes some of the devices, seal systems, and operating parameters encountered with turbines and compressors, but because of the magnitude of technical information that would be required, the ...
Balancing Of Multimass Flexible Rotors
(Texas A&M University. Gas Turbine Laboratories, 1976)
In this paper, we will consider only the problem of synchronous rotor response due to unbalance. There are numerous complex nonsynchronous vibrations that can occur in rotating machinery. Quite often the nonsynchronous ...
Field Testing Of Compressors
(Texas A&M University. Gas Turbine Laboratories, 1976)
An accurate evaluation of the performance of a dynamic rotary compressor is of paramount interest to the builder and user of this type of machinery because it defines the ability of a machine to perform a specific job and ...
Pulsations In Liquid Pumps And Piping Systems
(Texas A&M University. Gas Turbine Laboratories, 1976)
The existence of high intensity, low frequency pulsation problems in centrifugal compressor and pump piping systems has now been well documented throughout industry. Strong pulsations have been observed at frequencies ...
Turbomachinery Noise Rating
(Texas A&M University. Gas Turbine Laboratories, 1976)
An expression of the noise rating of a machine is an important part of its performance specification. Precautions should be taken, however, to make sure that the noise emission specification keeps the true objective in ...
Coupling Misalignment Forces
(Texas A&M University. Gas Turbine Laboratories, 1976)
Misalignment of machinery shafts causes reaction forces to be generated in the coupling which affect the machines and are often a major cause of machinery vibration. The reaction forces generated by the couplings are ...
Field Measurements Of Blade Stresses On Industrial Turbomachines
(Texas A&M University. Gas Turbine Laboratories, 1974)
High blade stresses can be induced in axial compressors by various asymmetrical flow conditions or adverse working conditions. A series of measurements were carried out on industrial and gas turbine axial compressors. After ...
Gas Turbines - High Efficiency Combined With Ease Of Maintenance
(Texas A&M University. Gas Turbine Laboratories, 1974)
The advent of jet propulsion as a form of prime mover during World War II spearheaded a tremendous surge in gas turbine technology which continues unabated today. As each new specification is issued for a gas turbine, the ...
Borescope Techniques Applied To Maintenance Practices On Marine Heavy-Duty Gas Turbines
(Texas A&M University. Gas Turbine Laboratories, 1974)
This paper describes the maintenance requirements of the Heavy-Duty Gas Turbine Marine Applications and the accessibility designed into the turbine to allow the operator to carry out both required repair work and classification ...
The Installation And Application Of Sensors For Turbomachinery Monitoring
(Texas A&M University. Gas Turbine Laboratories, 1974)
Turbomachinery performance quantities commonly monitored are bearing temperatures, thrust bearing load, and rotor vibration, speed, and axial position. Various sensors utilized in the monitoring function and installation ...
