Retrofit Of A Steam Turbine With Dry Gas Seals.
(Texas A&M University. Turbomachinery Laboratories, 1993)
The solution to a chronic utility problem, with a critical natural gas compression unit, at the Ammonia plant at Du Pont's Beaumont, Texas facility, is described. The most critical problem, chronic steam leakage from the ...
Design, Analysis, And Testing Of High Performance Bearings In A High Speed Integrally Geared Compressor.
(Texas A&M University. Turbomachinery Laboratories, 1994)
Analysis, design, and optimization of high performance journal and thrust bearings in a high speed integrally geared compressor are described. The high speed and relatively small bearing size stretches the applicable limits ...
Considerations And Issues In The Replacement Of A Centrifugal Compressor Train.
(Texas A&M University. Turbomachinery Laboratories, 1994)
The successful justification, design, installation, and commissioning of new major machinery in an existing petrochemical plant requires special consideration of many issues. This is particularly true in instances where ...
Analysis And Testing Of The Leg Tilting Pad Journal Bearing - A New Design For Increasing Load Capacity, Reducing Operating Temperatures And Conserving Energy.
(Texas A&M University. Turbomachinery Laboratories, 1994)
The repair of a turbine-compressor-expander to improve its mechanical reliability is described. The machine is unique, with two open-faced centrifugal compressor impellers in the center, three steam turbine stages overhanging ...
Temporary Repair Of A Large Axial Blast Furnace Motor-Blower As A Solution For A Steel Mill Operational Continuity.
(Texas A&M University. Turbomachinery Laboratories, 1992)
The repair work of a large axial blower that had its rotor and stator blades severely damaged is described. The 43 MW axial air blower is of critical importance for a large steel mill in Brazil, and the repair time was of ...
Applying The Probabilistic Fitness-For-Service Concept For Assessing Reliability Of Weld Repaired Steam Turbine Rotors.
(Texas A&M University. Turbomachinery Laboratories, 1992)
The cost savings and fast turnaround offered by weld repair of turbomachinery rotors results in significant advantages to the end user when faced with the possibility of having to replace the rotor. However, it also carries ...
An Experience With Nonstandard Coupling Application.
(Texas A&M University. Turbomachinery Laboratories, 1992)
The selection of flexible couplings is often considered to be routine because there are a variety of proven designs available. A compressor retrofit that required variance from standard coupling design practice is discussed, ...
A Comprehensive Cause Analysis Of A Coupling Failure Induced By Torsional Oscillations In A Variable Speed Motor.
(Texas A&M University. Turbomachinery Laboratories, 1993)
The analysis of two compressor train coupling failures that were caused by a subsynchronous torsional resonance is discussed. These torsional failures manifested themselves as fatigue cracks that propagated across the ...
