Designing Oil-Free Screw Compressor Systems for Acoustic Resonance During Shop Testing, Field Startup, and Process Operation
(Texas A&M University. Turbomachinery Laboratories, 2008)
An OFS (Oil Free Screw) compressor experienced problems meeting the API 619 3rd Edition vibration level acceptance criteria during shop testing. Extensive testing identified the primary mechanism that increased the rotor ...
Evaluation and Successful Modification of Impeller Using Forced Response Analysis
(Texas A&M University. Turbomachinery Laboratories, 2008)
Investigation of Corrosion Fatigue Phenomena in Transient Zone and Preventive Coating and Blade Design Against Fouling and Corrosive Environment for Mechanical Drive Turbines
(Texas A&M University. Turbomachinery Laboratories, 2008)
For mechanical drive steam turbines, the investigation results of corrosion fatigue phenomena in the transient zone are introduced, including basic phenomena on expansion line and actual design and damage experience. These ...
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 ...
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 ...
