Eliminating Oil Leaks By Optimizing Bearing Case Oil Labryinths.
(Texas A&M University. Turbomachinery Laboratories, 1998)
Many pieces of rotating equipment experience oil leaks. Any
piece of equipment with oil fed bearings, such as turbines, motors,
gearboxes, and compressors, are susceptible to oil leaks from the
bearing case seals. Usually ...
Experience With High Speed Induction Motors For Direct Driving Of Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1998)
This paper presents the high speed, high power induction motor as a viable alternative for direct driving of compressors. A comparison is made between the existing different mechanical and electrical solutions, and the ...
Redesign Of The Last Two Stages Of A Mechanical Drive Steam Turbine.
(Texas A&M University. Turbomachinery Laboratories, 1998)
A six stage mechanical drive steam turbine rated at 13,300 hp
was installed at a petroleum facility in Texas to drive a multistage
centrifugal compressor used in recycle gas service on a high
pressure hydrogen cracker. ...
Guidelines For Specifying And Evaluating New And Rerated Multistage Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1998)
Refineries, petrochemical companies, and gas processors are
continually trying to increase plant production while budgets are
getting tighter. Rerating process centrifugal compressors has
become an ever-increasing trend ...
Gas Turbine Blade Failures - Causes, Avoidance, And Troubleshooting.
(Texas A&M University. Turbomachinery Laboratories, 1998)
With blading problems accounting for as many as 42 percent of
the failures in gas turbines (Allianz, 1 978) and with its severe
effect on plant availability, there is a pressing need for a unified
treatment of the causes, ...
Synchronous Motor Lateral Vibration Dynamics - Diagnosis, Resolution, And Field Implementation.
(Texas A&M University. Turbomachinery Laboratories, 1998)
A large, double ended drive synchronous motor experienced
severe, limiting lateral vibration during commissioning of a major
plant expansion. The motor driving a centrifugal compressor
providing process air is decoupled ...
Advanced Dry Gas Seal By The Dynamic Ion Beam Mixing Technique.
(Texas A&M University. Turbomachinery Laboratories, 1998)
Ductile materials have been used for dry gas seal mating rings to
replace conventional sintered materials that have experienced
occasional brittle fracture. The ductile materials require a coating
to make them suitable ...
Development Of A Sulfidation - Corrosion Resistant Nickel-Base Superalloy For FCC Power Recovery Turbine Rotors.
(Texas A&M University. Turbomachinery Laboratories, 1998)
A nickel-base superalloy for FCC power recovery turbine rotors
was developed, which shows excellent sulfidation-corrosion
resistance, high temperature strengths, and hot workability.
To investigate the influences of the ...
