Discussion Group T14 On Wet and Dry Screw Compressors
(Texas A&M University. Turbomachinery Laboratories, 2011)
Coupling Credible Failure Modes and Owner Options to Intervene
(Texas A&M University. Turbomachinery Laboratories, 2013)
While all machine component failures can impact reliability, cost and production, some like coupling failures may have safety risks for personnel. Intervention requires us to build appropriate steps into our machine and ...
Dynamic Stress Measurement Of Centrifugal Compressor Impeller And Study For Strength Criteria Based On Correlation By Unsteady CFD
(Texas A&M University. Turbomachinery Laboratories, 2010)
Based on the development of numerical analysis techniques over the past decade, the engineer can easily model the internal flow conditions and vibration characteristics of turbomachinery. When focusing on vibration response ...
API 682 Arrangement 2 Configurations - Considerations for Outer Seal and Support System Design
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
API 682, now in its 4th Edition, has made a concerted effort to accurately define and distinguish between different types of seal configurations available under the designation of ‘Arrangement 2’, including 2CW-CW, 2CW-CS, ...
Solving a Sever Vibration Problem in the Downstream Piping of a Gear Pump
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
A solution was developed for an extreme discharge piping vibration problem on an 80 hp gear pump piping system. Maximum field-measured vibration levels were over 4 ips 0-pk (200 mm/sec pk-pk). Most gear pumps are not ...
Reverse Rotation Of Compressor - Drive Turbine Train Can Cause Major Damages (A Case Study of Delayed Coker Unit Wet Gas Compressor Drive turbine Barring Gear Damage Due to Reverse Rotation: Its Detection, Diagnosis & Correction)
(Texas A&M University. Turbomachinery Laboratories, 2012)
Limitations of ASME PTC 10 in Accurately Evaluation Centrifugal Compressor Thermodynamic Performance
(Texas A&M University. Turbomachinery Laboratories, 2013)
The American Society of Mechanical Engineers (ASME) “Performance Test Code on Compressors and Exhausters,” ASME PTC 10-1997, has served worldwide as the standard for determining centrifugal compressor thermodynamic performance ...
History of Gear Failures in a Steam Turbine Driven Integrally Geared Compressor
(Texas A&M University. Turbomachinery Laboratories, 2013)
Innovative Design in Expander Wheel-Shaft Attachment Replaces Hirth Coupling for High Speed, High Temperature and High Power Applications
(Texas A&M University. Turbomachinery Laboratories, 2013)
Expander-Generator unit for a geothermal power plant application experienced ongoing failures during a ten year period. The longest run cycle for the machine was 18 months yet with less than 10 MW power production. The ...
Capacity Improvement of Large, Two Stage Diaphragm Compressor
(Texas A&M University. Turbomachinery Laboratories, 2013)
Two stage diaphragm compressor is used to pressurize a process gas stream. As delivered, compressor produced less than 75% of the required flow rate at the specified suction and discharge conditions. Improvement Goal: ...
