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, ...
Large Adjustable Speed Drives And Their Application To A High Speed Centrifugal Compressor
(Texas A&M University. Turbomachinery Laboratories, 1981)
New applications are being found for adjustable speed drives due to: 1) the availability of high current solid-state devices, 2) a simplified inverter design with large scale integrated circuits (LSI), and 3) because of ...
Continuous Monitoring Systems For High Speed Gearing
(Texas A&M University. Turbomachinery Laboratories, 1982)
The most effective methods for monitoring the health of high speed gearing is currently generating more interest and discussion than any other aspect of machinery health monitoring. Both structurally and dynamically, a ...
Frequency Convertors For Starting And Speed Regulations Of AC Motors For Turbomachine Applications
(Texas A&M University. Turbomachinery Laboratories, 1981)
