General Purpose Steam Turbine Reliability.
(Texas A&M University. Turbomachinery Laboratories, 1991)
Several aspects of maintaining and operating small steam turbines at the A von Refinery are discussed. The discussion concentrates on areas that have historically resulted in unreliable performance and repetitive failures. ...
New Technology On High Performance And Reliability Of Mechanical Drive Steam Turbines.
(Texas A&M University. Turbomachinery Laboratories, 1991)
The new design technology of the mechanical drive steam turbines used in the chemical plant industry is presented. In order to improve the performance of high speed turbines, the new high pressure ratio impulse stage has ...
Reverse-Indicator Alignment And Related Subjects
(Texas A&M University. Gas Turbine Laboratories, 1980)
This paper is a discussion of reverse-indicator measurement and other alignment subjects. The basic steps in doing an alignment job and some of the tooling that can be used will be described.
Unique Fan Vibration Problems: Their Causes And Solutions
(Texas A&M University. Gas Turbine Laboratories, 1980)
Operating requirements for new fans demand that greater attention be given to the design of the total installation including everything from the foundation to the ducts. Rotor dynamic analysis without adequate consideration ...
Turbomachinery Problems - Lube And Seal System Revisited
(Texas A&M University. Gas Turbine Laboratories, 1978)
Even an apparently well-designed lube and seal system can and will cause turbomachinery problems to occur if all operating parameters are not considered in the design of the lube and seal system. Lube and seal system design, ...
Dynamic Simulation Of Centrifugal Compressor Systems
(Texas A&M University. Gas Turbine Laboratories, 1977)
The capacity, pressure, speed and horsepower of centrifugal compressors have been trending higher and higher in the past few years. Not only are machine designers faced with increasing aerodynamic and mechanical problems, ...
Improving Cooling Tower Fan System Efficiencies
(Texas A&M University. Gas Turbine Laboratories, 1978)
After a look at the problem for air cooled heat exchangers and cooling towers using axial fans, ways to improve system efficiencies in three areas are discussed: before the fin system design is finalized, improvements in ...
High-Speed Gear Vibration And Noise Experience
(Texas A&M University. Gas Turbine Laboratories, 1977)
High-speed gear pinion precession-shuttling and noise, caused by overhanging weight of the coupling and by misalignment forces generated by tooth friction in the coupling, are being controlled by reduced bearing clearances. ...
Installation Of Large Rotating Equipment Systems - A Contractor's Comments
(Texas A&M University. Gas Turbine Laboratories, 1976)
The profitability, reliability and maintenance of gas turbine driven centrifugal compressor units are not inherent with the machinery, but for the most part, depend on the piping system to which they are connected and the ...
Site Balancing Of A Large Flexible Rotor Containing Unbalance Eccentricity And Permanent Residual Bow
(Texas A&M University. Gas Turbine Laboratories, 1976)
When turbine-generators operating at constant speed require site trim balancing, this is most commonly performed at the synchronous speed using a conventional influence coefficient method. In some cases, the vibration of ...
