Stiles, David T.; Sandberg, Mark R.; Justak, John F.; Wilcox, Ed; Kuzdzal, Mark J.; Rohrs, Charles A.; Miller, Harry F. (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Test results for an ASME Power Test Code 10 (PTC) Type 1 test of a 4,500 psia (310 Bara) discharge pressure gas lift centrifugal compressor outfitted with dynamic pressure-balanced seals at the impeller eyes; shaft interstage ...

Determining The Root Causes Of Subsynchronous Instability Problems In Two Centrifugal Compressors. Wilcox, Ed; O'Brien, Dave P. (Texas A&M University. Turbomachinery Laboratories, 2003)This paper discusses the rotordynamic instability problems experienced with two separate centrifugal compressors. While the root causes of the instabilities are very different, the analysis methodology of reconciling the ...

Wilcox, Ed (Texas A&M University. Turbomachinery Laboratories, 2007)The paper describes the problems encountered and solutions that were implemented to improve the reliability of a high speed/high energy centrifugal pump. Two of these pumps were originally installed in 1984, with a third ...
-
Wilcox, Ed (Texas A&M University. Turbomachinery Laboratories, 2001)Modifications to a high-pressure, high-temperature barrel pump to increase seal reliability and throughout are discussed. The pump is in unspared hydrodewaxer (HDW) feed service. The original seal design included nonpressurized ...
-
Wilcox, Ed (Texas A&M University. Turbomachinery Laboratories, 2002)Accurate and meaningful condition monitoring is necessary to prevent both severe equipment damage and unnecessary shutdowns. One of the most important aspects of condition monitoring is the evaluation of startup and shutdown ...
-
Wilcox, Ed (Texas A&M University. Turbomachinery Laboratories, 1999)The cause and effects of a large subsynchronous vibration (3.5 mils at 3490 cpm) in an FCC wet gas compressor are examined. The compressor is driven at 7850 rpm by a 6000 hp electric motor, through a speed-increasing ...
-
Wilcox, Ed (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Turbomachinery requires a higher level of vibration analysis than general purpose machinery. This includes identifying natural frequencies or modes of a system to determine if a potential resonance occurs. The complexity ...
