Measuring The Thermodynamic Performance Of Multistage Compressors Operating On Mixed Hydrocarbon Gases
(Texas A&M University. Turbomachinery Laboratories, 1981)
Performance measurement of multistage centrifugal compressors is often required to assess their current operating condition, e. g., to discover fouling or to gauge the operation of the compressor in relation to the overall ...
Electromagnetic Shaft Current Problems A User's Viewpoint
(Texas A&M University. Turbomachinery Laboratories, 1981)
This article covers a user’s experience, viewpoint and resolution, with destructive stray shaft currents on a centrifugal split-case design compressor. The compressor is driven by a 33,000 HP 13-stage condensing turbine. ...
Guidelines For Performance Testing Centrifugal Compressor
(Texas A&M University. Turbomachinery Laboratories, 1981)
Performance testing of centrifugal compressors in the field is generally a compromise at best, and shop testing before delivery to the site is usually preferred. There are circumstances that dictate or suggest that the ...
Design Of Journal Bearings For Rotating Machinery
(Texas A&M University. Turbomachinery Laboratories, 1981)
Rotating machinery is often subject to vibrations due to critical speeds, unbalance, and instability. Usually the least expensive modification of a machine to make is the bearing. A wide variety of bearings have been ...
Realistic Design Specifications Increase Pump Reliability
(Texas A&M University. Turbomachinery Laboratories, 1981)
Many design specifications are incomplete relative to pumping system operation and can inadvertently place unrealistic restrictions on the pump designer. Meaningful cooperation between pump suppliers, architect/engineers ...
Measure Power By The Simplest Method And Use For Onstream Computer Monitoring
(Texas A&M University. Turbomachinery Laboratories, 1981)
Determining brake horsepower by means other than calculations of compressor performance for compression of hydrocarbon mixtures is usually the more accurate procedure for field testing. Various means of determining this ...
API 671 - Couplings What Is The Impact On The User?
(Texas A&M University. Turbomachinery Laboratories, 1981)
Flexible coupling are a very small part of turbomachinery train in terms of the total capital investment. In terms of its contribution to reliability, the flexible coupling takes on a more significant role. Unfortunately, ...
Material Coating By The Detonation Gun Process
(Texas A&M University. Turbomachinery Laboratories, 1982)
There are numerous methods available to repair compressor and turbine shafts when bearing journals, seal surfaces and other critical areas require resurfacing. One of these methods is by the use of detonating gun coatings. ...
Experimental Investigation Of Balancing Flexible Rotors In Large Motors And Generators
(Texas A&M University. Turbomachinery Laboratories, 1981)
The balancing of large motor and generator rotors is accomplished by a combination of balance machine corrections plus the calculated corrections determined by an Influence Coefficient Balancing computer program. The method ...
Techniques For More Accurate Centrifugal Compressor Performance Evaluation
(Texas A&M University. Turbomachinery Laboratories, 1981)
The evaluation of the installed performance of a centrifugal compressor unit involves two phases of effort. First, good field test data must be obtained on suction and discharge pressures and temperatures, rotating speed, ...
