-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)During the commissioning of centrifugal machines (Compressors, steam turbines, pumps, fans etc.), a lack of flushing, inspection and ignorance of critical areas & procedures can lead to major problems, damage, and serious ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)Dual mechanical seals represent one of the most common approaches to improving seal reliability and reducing process emissions. While the presence of the pressurized barrier fluid provides significant benefits, the challenge ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Tutorial 18: Understanding the lateral rotordynamic behavior is critical in determining the reliability/operability of rotating equipment. Whether examining a centrifugal pump or compressor, steam or gas turbine, motor or ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)This case study outlines how structural vibration was resolved using two different technologies and highlighting secondary issues that can arise due to continued vibration because of structural resonance. Continued high ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Tutorial 6: Experimental modal analysis and operating deflection shapes (ODS) are powerful tools in vibration analysis and machinery troubleshooting. However, the machinery plant engineer often doesn’t believe such techniques ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Case Study 22: Over a 13‐year span, a major South American oil company’s maintenance department fought high vibrations in three gas reinjection compressor trains. To reduce the chances of machine trips, technicians field ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Lecture 3: Variable-frequency drives (VFDs) are being increasingly employed in oil and gas (O&G) applications due to their better efficiency, reliability and process control when compared to conventional drives. In comparison ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Lecture 15: Squeeze Film Dampers (SFDs) are effective means to ameliorate rotor vibration amplitudes and to suppress instabilities in rotor-bearing systems. A SFD is not an off-the-shelf mechanical element but tailored to ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Tutorial 2: In many cases it is necessary to judge the stability behavior of a specific compressor. This might be the OEM checking the feasibility of a proposed compressor layout or it might be the user judging one of his ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)Annular seals are non-contacting mechanical elements designed to reduce leakage between two areas of differing pressures such as between two impeller stages in a pump. Circumferential fluid rotation inside the annular ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)The governor actuator for a steam turbine was observed to be hunting and failed to maintain stable operating speed. The steam turbine is used to drive a centrifugal compressor for H2 service in a recycle loop. The extent ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)The Wet Gas compressor is one of the most critical assets in a FCCU/RCCU of a oil refinery. The back pressure steam turbine driver of this compressor faced two failures in the main valve stem of the steam inlet valve. ...
