A Mathematical Formalism For Flexural Diaphragm Fatigue Life And Reliability Evaluation.
(Texas A&M University. Turbomachinery Laboratories, 1996)
A mathematical formalism is presented for flexural diaphragm fatigue life and reliability evaluation. The use of this formalism enables the diaphragm designer to match a customer's requirements for life and reliability, ...
A Systematic Approach To Case Recertification.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Turbomachinery life expectancy, economic conditions, and plant capacity enhancements have created a need for vintage compressors to be reevaluated and re-engineered for operational parameters that may not have been ...
Design Improvements Enhance Dry Gas Seal's Ability To Handle Reverse Pressurization.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Within the past three years, refrigeration compressors operating intermittently at subatmospheric pressures have experienced two dry gas seal failures which have been attributed, either all or in part, to reverse pressurization ...
Thrust Bearing Analysis, Optimization, And Case Histories.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Babbitted oil film thrust bearings as used in industrial turbomachinery
are discussed. The majority of the presentation covers tbe
higher performance tilting pad thrust bearings as found in most
critical rotating ...
Applying Variable Speed Drives With Static Frequency Converters To Turbomachinery.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Today, the variable speed drive with AC motor and static frequency converter is an outstanding solution to control the speed of turbomachines in the power range up to 100 MW and more. A wide selection of variable speed ...
Dynamic Data Analysis Of Compressor Rotating Stall.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Techniques for rotating stall verification and analysis of detrimental effects are described. Majority of dynamic pressure data presented herein are from centrifugal compressors, including one unit that required field ...
Expander Field Remanent Life Analysis And Assessment.
(Texas A&M University. Turbomachinery Laboratories, 1996)
The operating temperatures of hot gas expanders can cause degradation in the material capabilities of both the rotating and stationary components. For this reason, many of the components of the expanders are life limited. ...
Rotating Equipment Loss Prevention - An Insurer's Viewpoint.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Accidents involving rotating equipment in chemical, petrochemical,
petroleum, and gas plants can result in damage to other
process equipment and catalysts along with lost production.
Conversely, process upsets, process ...
Design Considerations For Thrust Bearing Applications.
(Texas A&M University. Turbomachinery Laboratories, 1996)
The hydrodynamic thrust bearing load capacity-speed envelope is divided into three major regions by speed. Each region has its own set of limiting physical phenomenon that must be included in the analysis and presents a ...
Surge Detection In An Industrial Axial Flow Compressor.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Compressor surge can be a disruptive and potentially destructive phenomena in turbocompressors. A surge detection scheme utilized in shop and field testing of a 29,600 hp (22 MW) industrial axial compressor is described. ...
