Design and Mitigation Techniques for Applications with Possible Liquid Contamination of the Sealing Gas Dry Gas Seal System
(Texas A&M University. Turbomachinery Laboratories, 2008)
A compressor in a natural gas gathering service experienced multiple seal failures on the discharge end. Synthetic oil mist contained in the sealing gas was identified as a significant source of contamination that caused ...
Analysis and on-stream countermeasures of sub-synchronous vibration of a centrifugal compressor
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
The sub-synchronous vibration could be attributed to many causes such as gas-whirl, oil whirl, looseness and so on. To prevent sub-synchronous vibration, manufacturer analyzes stability during design stage. But field ...
Solving Structural Vibration Problems Using Operating Deflection Shape (ODS) Analysis
(Texas A&M University. Turbomachinery Laboratories, 2008)
Seal Oil Piping Vibration On An Oil-Free Screw Compressor In An FPSO Application.
(Texas A&M University. Turbomachinery Laboratories, 2009)
A dry screw compressor skid was fabricated for offshore service that included oil buffered mechanical seals on the compressor. During shop testing, excessive seal oil piping vibration was observed that resulted in pipe ...
Successful Avoidance Of Major Secondary Damages Using Proximity Measurements To Detect A Partially Fractured Piston Rod.
(Texas A&M University. Turbomachinery Laboratories, 2009)
75mw Turbine-Generator Journal/Thrust Bearing Upgrade.
(Texas A&M University. Turbomachinery Laboratories, 2009)
This case history discusses the upgrade of the #1 combination journal-thrust bearing assembly in the front standard of a 75 MW turbine/generator set. The existing taper land thrust plates experienced frequent failures and ...
Centrifugal Compressor Degradation Detection Through Remote Vibration Monitoring.
(Texas A&M University. Turbomachinery Laboratories, 2009)
An example of availability gain using vibration remote monitoring systems for early diagnostic.
Aeroacoustic Phenomena In High Pressure Centrifugal Compressors - A Possible Root Cause For Impeller Failures.
(Texas A&M University. Turbomachinery Laboratories, 2009)
During the past decades studies of aeroacoustic phenomena in turbomachinery were mainly carried out by research institution. The aerospace industry was the main driver in this field since noise issues gained more and more ...
Development And Application Of A Vertical High Speed Motor-Compressor Simulator For Rotor Drop Onto Auxiliary Bearings.
(Texas A&M University. Turbomachinery Laboratories, 2009)
During the conceptual development of a subsea motor-compressor prototype running on active magnetic bearings, the emergency landing on the catcher bearings was identified as a potential technology gap. This is because the ...
Assessing Liquid Droplet Erosion Potential In Centrifugal Compressor Impellers.
(Texas A&M University. Turbomachinery Laboratories, 2009)
This paper presents a method for estimating the potential for liquid droplet erosion in compression system components, such as the impeller of centrifugal compressors. The erosion model selected is used to calculate a ...
