Turbomachinery Symposium (32nd : 2003) (Texas A&M University. Turbomachinery Laboratories, 2003)
-
Jummonville, Jigger; Yates, Kevin (Texas A&M University. Turbomachinery Laboratories, 2003)Magnetic bearings continue to be successfully applied throughout industry. As the population of machines using magnetic bearings grows, so does the interest in the appropriate predictive and preventive maintenance (PPM) ...

Ross, Stephen L.; Beckinger, Raymond F. (Texas A&M University. Turbomachinery Laboratories, 2003)The sealing of rotating equipment has always presented a special challenge for rotating equipment manufacturers and end users. Shaft seals are provided to restrict or prevent the escape of process or sealing fluids to ...

Nordwall, Grant; Jummonville, Jigger; Matthews, Terryl (Texas A&M University. Turbomachinery Laboratories, 2003)For several decades, turboexpander designers have relied on experience and traditional design tools to create their products. Recent advances in CFD (computation fluid dynamics) software and desktop computing power have ...

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 ...

Wang, Wenchao; Downson, Phillip; Baha, Amir (Texas A&M University. Turbomachinery Laboratories, 2003)Two coatings have been developed for petrochemical compressor antifouling and corrosion resistance purposes. One is a multilayer composite coating with a modified polytetrafluoroethylene (PTFE) impregnated organic topcoat, ...

Hardin, Jim; Kushner, Frank; Koester, Stephen (Texas A&M University. Turbomachinery Laboratories, 2003)This paper describes two steam turbine governor valve failures in the same installation, the troubleshooting that determined the root cause, and the new valve designed to prevent similar failures. The original governor ...
-
Li, Jiming; De Choudhury, Pranabesh; Kushner, Frank (Texas A&M University. Turbomachinery Laboratories, 2003)Stringent stability screening criteria by the American Petroleum Institute (API) result in higher level rotor stability analyses to be performed on more intermediate-pressure compressor rotors and in more detail. These ...
-
Koring, Rolf (Texas A&M University. Turbomachinery Laboratories, 2003)There are differences between European and US bearing metals. This paper shows the mechanism for improving the properties of bearing alloys and the environmental problems that have arisen so far in this connection. Since ...
-
Camatti, Massimo; Vannini, Giuseppe; Fulton, John W.; Hopenwasser, Fred (Texas A&M University. Turbomachinery Laboratories, 2003)A two casing (three-stage) high-pressure injection compressor train driven by a gas turbine via a gearbox was full load and full speed performance tested to demonstrate satisfactory aerothermal and rotordynamic performance. ...
-
Stahley, John S. (Texas A&M University. Turbomachinery Laboratories, 2003)In today’s business environment, centrifugal compressor reliability is more critical than ever. Unscheduled equipment downtime has a negative impact on plant operations, oftentimes resulting in a temporary halt of production. ...
-
Thomson, William T.; Gilmore, Ronald J. (Texas A&M University. Turbomachinery Laboratories, 2003)Induction motor drives are the most widely used electrical drive system and typically consume 40 to 50 percent of an industrialized nation’s total generating capacity. In the USA the total generating capacity is approximately ...
-
Carbonetto, Ben (Texas A&M University. Turbomachinery Laboratories, 2003)Expander reliability has been limited by flow path erosion, corrosion, and deposition. Through root cause determination of the failures and laboratory testing, advances in machine designs and online monitoring and cleaning ...

Turbomachinery Symposium (32nd : 2003) (Texas A&M University. Turbomachinery Laboratories, 2003)
-
Locke, Stephen R.; Faller, Wolfgang (Texas A&M University. Turbomachinery Laboratories, 2003)A process recycle gas compressor was needed that would be highly reliable and tolerant of suction contaminants of sticky material that is abrasive and corrosive. Squeeze film dampers, pinched diffusers, and other technologies ...
-
Singh, Murari P.; Thakur, Bhabesh K.; Sullivan, William E.; Donald, George (Texas A&M University. Turbomachinery Laboratories, 2003)The reliability of centrifugal compressors for the most part depends on the reliable operation of impellers. Most of the time, damage to impellers is due to mechanical fatigue. Fatigue damage has been observed in blades, ...

Whalen, John K.; Leader, Malcolm E. (Texas A&M University. Turbomachinery Laboratories, 2003)A new cogeneration installation was in the process of being commissioned when severe subsynchronous vibration was detected on the generator during no load tests. Subsequently, two rotordynamics problems were discovered. ...
