Reducing ANSI Pump Maintenance Costs Through Component Upgrades
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1987)
Standard ANSI pumps are adequate for most services. In installations where they do not give adequate service, however; upgrades are available to improve reliability. These should be selectively applied to obtain the maximum ...
Experience With Periodic Vibration Monitoring In Fossil Power Stations.
(Texas A&M University. Turbomachinery Laboratories, 1987)
Results are presented from data obtained from the cumulative experience of eight utilities which are conducting periodic, computer based predictive maintenance (PM) programs at their fossil stations. These programs are ...
Conversion Of A 19,000 HP Propylene Compressor Drive From Steam Turbine To Electric Motor With Geared Cariable Speed Turbo Coupling.
(Texas A&M University. Turbomachinery Laboratories, 1987)
In the course of modernizing an ethylene plant in 1985, Union Rheinische Braunkohlen Kraftstoff AG converted a propylene compressor with 4 process stages from a steam turbine drive to an electric motor drive. The economic ...
Subsynchronous Vibration Problem And Solution In Multistage Centrifugal Compressor.
(Texas A&M University. Turbomachinery Laboratories, 1987)
The investigation of a subsynchronous vibration problem encountered in a six stage centrifugal compressor is discussed. At a running speed of approximately 9000 rpm, a subsynchronous vibration (at 4200 rpm) of nearly two ...
Application Ion-Plated Cr-Tin Multilayer Coating To Steam Turbine Blades.
(Texas A&M University. Turbomachinery Laboratories, 1987)
In order to apply a recently developed ion-plated coatings to compressor driving steam turbine blades, cavitation erosion tests were conducted to select the effective multilayer coating to prevent drain erosion of the ...
New Solutions In The Process Industry - Application Of Six-Stage Integrally Geared Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1987)
At the end of the forties, the integrally geared centrifugal compressor was developed and initially used for air, and later for nitrogen and other gases. To date, about 10,000 units are in use working in the capacity range ...
Electric Shaft Currents In Turbomachinery.
(Texas A&M University. Turbomachinery Laboratories, 1987)
Electrical damage to turbomachinery parts has caused a number of machinery failures and many hours of costly downtime. The problem of electrical voltages and currents being generated in non-electrical machines has puzzled ...
