General Purpose vs. Special Purpose Couplings.
(Texas A&M University. Turbomachinery Laboratories, 1994)
Flexible couplings are a vital part of a power transmission system. What type is selected, how much the coupling costs, and how much effort one spends on selecting a coupling and determining how it interacts with a system ...
Process Safety Management.
(Texas A&M University. Turbomachinery Laboratories, 1994)
Impeller Repair Techniques For Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1994)
Successfully repairing centrifugal compressor impellers requires careful consideration and planning. The selection of techniques for inspection, material, and welding procedures are determined by numerous factors. Original ...
Selection Of Turbomachinery - Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1994)
One of the primary functions of the rotating machinery engineer is the application and selection of turbomachinery. During the early stages of a project, the process engineer needs to know the performance of turbomachinery, ...
Retuning A Gear Disc Profile To Eliminate High Gear Vibration.
(Texas A&M University. Turbomachinery Laboratories, 1994)
High gear case acceleration levels, experienced during shop string testing of a compressor train, were traced to gear element structural resonance, which was excited by the gear tooth meshing frequency. Finite element ...
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 ...
Reliability Improvements To A High Pressure, High Temperature, Thirteen Stage Charge Pump
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1994)
Reliability of a high pressure charge pump has been a problem for over 20 years. Unplanned unit outages and sometimes fires accompany pump failures. This paper details the joint effort of the OEM and the user to resolve ...
Rotating Equipment Pump Reliability Upgrading Project
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1994)
In 1988, a general performance assessment was undertaken at Shell UK’s Stanlow Manufacturing Complex to review its competitive position in the market place. The review concluded there was a high level of maintenance ...
