Real Time Spectral Analysis-Taking The Mystique Out Of This Valuable Maintenance Tool
(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 ...
Maintenance Techniques For Turbomachinery
(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 ...
Cold And Hot Alignment Techniques Of Turbomachinery
(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.
On-Stream Cleaning Of Turbomachinery
(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 ...
Rotor-Bearing Stability
(Texas A&M University. Gas Turbine Laboratories, 1972)
This paper presents a survey of the various mechanisms that can cause instability in rotor bearing systems. The occurrence of self-excited instability is of particular importance to the manufacturers and users of modern ...
Industrial Gas Turbine Performance Measurement
(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 ...
The Large Power-Output Radial Inflow Turbine
(Texas A&M University. Gas Turbine Laboratories, 1974)
The performance of advanced radial inflow (RIF) turbines is reviewed and new results of stress and blade vibration analysis are presented. Due to the development of modern manufacturing techniques, large radial inflow ...
Conversion Of A Single-Shaft Turboprop Engine To A Two-Shaft Industrial Turbine
(Texas A&M University. Gas Turbine Laboratories, 1973)
Critical Areas In Centrifugal Compressors
(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 ...
Field Performance Testing Of Centrifugal Compressors
(Texas A&M University. Gas Turbine Laboratories, 1974)
The paper describes the type of data that must be recorded in order to performance test a centrifugal compressor in the field. The instrumentation required to measure different test parameters is also discussed. The need ...
