Compressor Drive Trubines Of High Efficiency And Great Operational Safety
(Texas A&M University. Gas Turbine Laboratories, 1977)
Steam turbines employed as mechanical drivers require special design features. The problems confronting a turbine designer arc blade and shaft vibrations, bending and centrifugal stresses, torsional analyses as well as ...
Machinery Monitoring Update
(Texas A&M University. Gas Turbine Laboratories, 1977)
This paper describes and economically justifies one major oil company's utilization of a total Integrated Mechanical Inspection Program as an alternative to high maintenance costs and reduced plant productivity.
Rejuvenation Of Used Turbine Blades By Hot Isostatic Processing
(Texas A&M University. Gas Turbine Laboratories, 1977)
The creep properties of gas turbine blades will deteriorate with prolonged service exposure. This deterioration is primarily due to internal microstructural changes and the formation of creep voids or cavitation. Development ...
Fluid Film Bearings - Fundamentals And Design Criteria And Pitfalls
(Texas A&M University. Gas Turbine Laboratories, 1977)
The presentation will cover fluid film bearing fundamental theory and design criteria. Since the subject is extensive, the design portion will be restricted to hydrodynamic (self-acting) bearing mode using liquid lubricants. ...
Industrial Steam Turbines Improve Energy Utilization In Thermal Power Plants
(Texas A&M University. Gas Turbine Laboratories, 1976)
Owing to high fuel costs, European Companies have always had to use special care in planning their process-energy requirements. Therefore, the industrial steam turbine has also played a major part in this respect. The ...
Reliable Overspeed Protection For Industrial Drive Turbines
(Texas A&M University. Gas Turbine Laboratories, 1976)
The paper discusses the fundamental relationships between turbine overspeed and the time constant of the rotor. The amount of overspeed is shown to be related not only to the time lag of the emergency tripping devices, but ...
Electromagnetic Shaft Currents And Demagnetization On Rotors Of Turbines And Compressors
(Texas A&M University. Gas Turbine Laboratories, 1978)
A high percentage of large, high-speed compressor trains has suffered serious failures which were initiated by shaft current damage. These currents are generated by electromagnetic effects. The basic mechanics of various ...
An Investigation Of The Flexural Vibration Behavior Of Slender Rotors In Drum-Type Condensing Turbines
(Texas A&M University. Gas Turbine Laboratories, 1978)
With turbine rotors of low shaft elasticity (large diameter and small bearing span) the increase in amplitude at the first point of shaft resonance in the speed range is generally slight. Consequently no particular attention ...
Torsional Vibration Of Machine Systems
(Texas A&M University. Gas Turbine Laboratories, 1977)
This paper is concerned with torsional vibration in the design, development, and fault diagnosis and correction of machine systems. The physical behavior of torsional vibrations in shafting systems and sources of torsional ...
High Speed Gears - Design And Application
(Texas A&M University. Gas Turbine Laboratories, 1977)
High speed gear drives can be reliable if all the factors influencing their design, application, and operation are considered during the design stages. This paper will discuss the parameters used by gear engineers and the ...
