Influence Of Gas Seals On Rotor Stability Of A High Speed Hydrogen Recycle Compressor.
(Texas A&M University. Turbomachinery Laboratories, 1988)
A gas seal retrofit project for a 2800 hp, 10200 rpm, five-stage hydrogen recycle compressor is described. This barrel-type compressor operates with a 1205 psia suction pressure and 1490 psia discharge pressure. The unit ...
Safe Diagram - A Design And Reliability Tool For Turbine Blading.
(Texas A&M University. Turbomachinery Laboratories, 1988)
The complex field of turbine blade vibration has long been in need of improved tools to help predict the reliability of blading. The SAFE interference diagram is presented as such a tool. It presents much more information ...
Vacuum Distillation Methods For Lube Oils Increase Turbomachinery Reliability.
(Texas A&M University. Turbomachinery Laboratories, 1988)
The lube oils in self-contained reservoirs for turbomachinery in hydrocarbon processing plants are subject to contamination and deterioration from airborne dust, component debris, system corrosion, heat, and water. Oil ...
Application Of Dry Gas Seals On A High Pressur Hydrogen Recycle Compressor.
(Texas A&M University. Turbomachinery Laboratories, 1988)
Maintenance and operation of high pressure seal oil systems on centrifugal compressors has been a major problem faced by refinery operators. This problem is intensified when sealing gases like hydrogen and mixtures of ...
Water Contamination Of Steam Turbine Lube Oils - How To Avoid It.
(Texas A&M University. Turbomachinery Laboratories, 1988)
Ever since steam turbines have been built, contamination of the lube oil by water has been a persistent problem. Water contamination will result in rusting of ferrous components, accelerate sludging leading to sticking of ...
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 ...
Design, Testing And Commissioning Of A Synchronous Motor-Gear-Axial Compressor.
(Texas A&M University. Turbomachinery Laboratories, 1983)
This paper presents the design features involved in providing two air compressor trains at high efficiency. Testing and commissioning data are also presented, including specific electrical requirements; foundation and ...
Rotor Dynamics Modification Of An Eight Stage Compressor For Safety/Reliability Improvement.
(Texas A&M University. Turbomachinery Laboratories, 1983)
The catastrophic failure of a high pressure centrifugal air compressor utilizing air-pressurized bearing housings dictated the redesign of its sister compressor. The modification of this early 1950's compressor involved ...
