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: ...
Buying / Selling Serial #1
(Texas A&M University. Turbomachinery Laboratories, 2011)
The machinery utilized in the Oil and Gas Industry, (Upstream, Midstream and Downstream) is undergoing very significant changes. In the past years, the use of new designs or prototype machinery was strongly discouraged. ...
Operation Of Centrifugal Compressors In Choke Conditions
(Texas A&M University. Turbomachinery Laboratories, 2011)
Centrifugal compressors are at times required to operate in or near the choke region. Various limits of the degree of allowable operation in choke have been established. Based on test data and numerical data, the behavior ...
Development of a Texas Building Registry
(Energy Systems Laboratory (http://esl.tamu.edu), 2010-08)
The Texas Building Registry (TBR or Registry) provides data collection, storage, and analysis of above-code residential housing construction in Texas. The original system was developed to support the Texas Emissions Reduction ...
Range Vs. Efficiency—Striking The Proper Balance
(Texas A&M University. Turbomachinery Laboratories, 2011)
The paper addresses the balance between peak attainable efficiency and overall operating range that must be addressed when specifying, designing and/or selecting centrifugal compressors. The relative roles of the various ...
