Using A Damper Seal To Eliminate Subsynchronous Vibrations In Three Back-To-Back Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1995)
A new type of labyrinth seal that reduces cross coupled rotor forces and produces a remarkable amount of damping has been invented at Texas A&M University. Laboratory tests have shown complete elimination of critical speeds ...
Thermal Effects In Hydrodynamic Journal Bearings Of Speed Increasing And Reduction Gearboxes.
(Texas A&M University. Turbomachinery Laboratories, 1995)
The objective of this work is to minimize the maximum bearing temperatures under severe operating conditions in speed increasing and reduction gearboxes, and to present experimental data to validate the theoretical ...
Improved Reliability Through The Use Of Design Audits.
(Texas A&M University. Turbomachinery Laboratories, 1995)
Rotordynamic design audits of machinery and systems can be used to identify potential problems before manufacture, thus preventing costly project delays and downtime. Machinery engineers need to understand the types of ...
User Insights For The Effective Purchase Of New Turbomachinery.
(Texas A&M University. Turbomachinery Laboratories, 1995)
As organizations reengineer to become more competitive and as people are exposed to the purchase of new machinery in an increasingly competitive international market, an acquaintance with the activities needed for effective ...
Leakage And Rotordynamic Effects Of Compressible Annular Seals.
(Texas A&M University. Turbomachinery Laboratories, 1995)
Tilting Pad Journal Bearing Pivot Design For High Load Applications.
(Texas A&M University. Turbomachinery Laboratories, 1995)
Reducing pivot stress, pivot wear and preventing pivot failure are major design challenges encountered by tilting pad bearing designers in the extremely high load regime where the bearing unit load may often range up to ...
The Design And Application Of A Squeeze Film Damper Bearing To A Flexible Steam Turbine Rotor.
(Texas A&M University. Turbomachinery Laboratories, 1995)
A critical multistage steam turbine in a large chemical plant experienced high vibration levels and frequent repairs. Numerous failures occurred while passing through the rotor's first critical speed including heavy rubs. ...
Centrifugal Pump Application - Key Hydraulic And Performance Criteria
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
The essential elements to be reviewed when considering a centrifugal pump application are highlighted. The purpose is to ensure the procurement and/or application of a centrifugal pump which optimizes reliability, energy ...
Design And Implementation Of A Mechanical Seal Improvement Program At An Oil Refinery
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
A mechanical seal improvement program was initiated at a major oil refinery. The program was intended to improve seal reliability, reduce emissions, improve safety, and reduce costs. A partnership agreement was reached ...
The Effects Of Valve Dynamics On Reciprocating Pump Reliability
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
Compared to leading edge technologies such as high speed turbomachinery, reciprocating pumps may appear to be a simple technology: A reciprocating plunger causes liquid to be drawn from a low pressure manifold through the ...
