Some Aspects Of Field Performance Testing
(Texas A&M University. Turbomachinery Laboratories, 1981)
The incentives are well recognized for conducting field performance tests on centrifugal compressors in petrochemical service. From the maintenance standpoint, stage-by-stage changes in thermodynamic performance are valuable ...
An Improved Method For Calculating Critical Speeds And Rotordynamic Stability Of Turbomachinery
(Texas A&M University. Turbomachinery Laboratories, 1981)
A number of the computer programs for rotordynamic stability and critical speed prediction in common use during recent years have been based on the works of Myklestad, Prohl and Lund. Programs of this type, called transfer ...
Magnetism In Turbomachinery
(Texas A&M University. Turbomachinery Laboratories, 1981)
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, ...
