(Texas A&M University. Gas Turbine Laboratories, 1973)As the decade of the 1970's gradually unfolds, it becomes clear that it will be a decade of challenge for many of you who are engaged in the Process, Pipeline, or Electric utility Industries. The changing 11orld supplies ...
-
(Texas A&M University. Gas Turbine Laboratories, 1973)Optical alignment is a technique which has proven its usefulness in original installation, repair and maintenance of turbomachinery. Optical alignment, sometimes referred to as optical tooling utilizes precision optical ...

(Texas A&M University. Gas Turbine Laboratories, 1973)
-
(Texas A&M University. Gas Turbine Laboratories, 1973)Consideration of the materials for use in rotating machinery must begin with careful study and appraisal of expected operating conditions. In the discussion which follows, attention is concentrated on centrifugal compressors, ...
-
(Texas A&M University. Gas Turbine Laboratories, 1973)To properly install, profitably operate, and economically maintain high speed rotating machinery requires considerable skill, judgment, and experience. Excellent engineering references covering the mechanical design and ...
-
(Texas A&M University. Gas Turbine Laboratories, 1973)Gas turbines have been experiencing hot corrosion problems for over 25 years. These problems comprise two main types: vanadium attack and sulfidation. This paper deals with the problem of sulfidation corrosion, a name which ...
-
(Texas A&M University. Gas Turbine Laboratories, 1973)A new "yardstick" for measuring rotating machinery vibration is seen in the real time spectrum analyzer. This paper presents some actual case history data that was analyzed using a real time spectrum analyzer. The object ...
-
(Texas A&M University. Gas Turbine Laboratories, 1973)Manufacture and maintenance of turbomachinery are completely different. The first involves shaping and assembling of various parts to required tolerances while the second involves restoration of these tolerances through a ...
-
(Texas A&M University. Gas Turbine Laboratories, 1973)The first five years of vibration analysis work on turbomachinery indicated that 60% of the problems encountered were a result of casing-to-casing misalignment.
-
(Texas A&M University. Gas Turbine Laboratories, 1973)On-stream cleaning is regularly practiced on the axial compressors of gas turbines and on steam turbines. Many other turbo machines could be cleaned in service. In fact, the limiting factor is not the machine type, but the ...

-
(Texas A&M University. Gas Turbine Laboratories, 1973)In recent years mechanical equipment has seen extensive uprating in the form of higher speeds, pressures, temperatures and power levels. The advance in the equipment has reflected itself in making economically feasible ...
-
(Texas A&M University. Gas Turbine Laboratories, 1973)The aircraft-derivative gas turbine as a stationary ground-based prime mover has achieved a spectacular record in its short history of 13 years. During October 1960, in a remote Kentucky gas compressor station located on ...
-
(Texas A&M University. Gas Turbine Laboratories, 1973)Vibration problems in turbomachinery occur due to many factors. Some of the problems could have been prevented if more detailed design analyses were performed. Other times the problems occur due to design extrapolations ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(Texas A&M University. Gas Turbine Laboratories, 1974)Optical alignment as we know it today was borne out of the aircraft construction industry. With the advent of necessity to maintain a straight line within closer tolerances and over greater distances, precision instrument ...
-
(Texas A&M University. Gas Turbine Laboratories, 1974)An accurate assessment of the performance of an industrial gas turbine, in service, has been the goal of many test programs initiated by users and manufacturers alike. The rewards of such programs often are quite skimpy ...
