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 ...
Axial Vibration Characteristics Of Metal-Flexing Couplings
(Texas A&M University. Gas Turbine Laboratories, 1976)
Increased usage of metal-flexing couplings on high-speed rotating machinery has created awareness of the axial resonant vibration characteristics of this type of coupling. A testing program has been conducted at Rexnord ...
Large High Pressure Centrifugal Compressors For Oxygen Service
(Texas A&M University. Gas Turbine Laboratories, 1976)
Centrifugal compressors have been used to compress oxygen for at least 25 years. Until ten years ago, the flows were relatively small and discharge pressures were relatively low. In the mid 1960's the size of single train ...
Practical Design Solutions For Mechanical Drive Steam Turbines
(Texas A&M University. Gas Turbine Laboratories, 1976)
Following a review of possible alternative solutions regarding the choice of a mechanical driver; i.e., electric motor, gas turbine or steam turbine, it is demonstrated that the steam turbine as applied in industry is ...
Advanced Research Programs In Turbomachinery
(Texas A&M University. Gas Turbine Laboratories, 1976)
The objective of this paper is to acquaint the reader with the developments in the field of turbomachinery. The research conducted at the Gas Turbine Laboratories has two primary goals. First, to improve the efficiency of ...
Problems Encountered In Boiler Feed Pump Operation
(Texas A&M University. Gas Turbine Laboratories, 1976)
Although mechanical and hydraulic instabilities in centrifugal pumps caused a considerable amount of problems for large Nuclear and Fossil Generating Stations influencing "Power Plant Availability," a relatively limited ...
Efficiency In Mechanical Drive Steam Turbines
(Texas A&M University. Gas Turbine Laboratories, 1976)
With cost of energy in the $2.00 per 10^6 BTU range throughout the Western Industrialized World, the current value of one horsepower over a five-year period is in excess of $600. This high energy valuation is of relatively ...
Distortion Of Speed Changer Housings And Resulting Gear Failures
(Texas A&M University. Gas Turbine Laboratories, 1976)
Gear case distortion due to thermal effects has caused unique and costly failures at several of Union Carbide's process plants. The unusual nature of these failures has prompted us to make an in-depth logical investigation ...
Metal Diaphragm Coupling Perfomance
(Texas A&M University. Gas Turbine Laboratories, 1976)
The performance of a Metal Diaphragm Coupling is to a large extent determined by its endurance limit. The endurance limit can be estimated by calculations but must be confirmed through testing. The author cites data obtained ...
