Effects Of High Suction Energy In A Vacuum Tower Bottoms Pump Design
(Texas A&M University. Turbomachinery Laboratories, 2007)
Identification Of Bearing Housing Vibrations Of A Large Barrel Type Injection Pump And Their Analysis By Means Of The Finite Element Method
(Texas A&M University. Turbomachinery Laboratories, 2005)
It should be an objective to predict bearing housing vibrations by means of finite element methods and avoid them in the design phase rather than to go in for corrective actions on the test bed or in the field. Bearing ...
Optimizing The Asset Management Of Pumps Through Integrated Online Monitoring
(Texas A&M University. Turbomachinery Laboratories, 2005)
Effective asset management strives to maximize reliability and performance while minimizing maintenance and operation costs. Asset management improvement is possible by integrating new advances in smart online pump monitoring ...
Processes And Pump Services In The LNG Industry
(Texas A&M University. Turbomachinery Laboratories, 2005)
The liquefied natural gas (LNG) industry continues to grow worldwide, and there are many LNG terminals planned for the US in response to growing natural gas demands. This tutorial covers the LNG supply chain with emphasis ...
Centrifugal Pump Cooling And Lubricant Application - A "Best Technology" Update
(Texas A&M University. Turbomachinery Laboratories, 2005)
Process pumps experience widely different operating times to failure. U.S. refineries achieve pump mean-times-between-failure (MTBFs) ranging from less than three years to in excess of eight years. While the importance of ...
A Very High Head Pump
(Texas A&M University. Turbomachinery Laboratories, 2005)
Preliminary process design in 1997 for a new grass roots polymer unit in the Gulf Coast raised the possibility of using a single centrifugal pump instead of two reciprocating compressors to feel ethylene into the reactors. ...
Design And Development Of Electric Submersible Pumps For Large Capacities
(Texas A&M University. Turbomachinery Laboratories, 2005)
A submerged electric (SE) pump has been designed and analyzed for high flow applications. The challenges when designing a high power density SE pump are torsional and lateral dynamics and hydraulic stability. The case ...
Designing An Ultra-Low Specific Speed Centrifugal Pump
(Texas A&M University. Turbomachinery Laboratories, 2005)
Traditional commercial centrifugal pump designs have specific speeds (Ns) greater than 500 because low values of Ns are usually associated with low efficiency, pulsation, and a drooping head characteristic. In this instance, ...
Use Of Inducers In Liquified Petroleum Gas And Condensate Service For Better Performance
(Texas A&M University. Turbomachinery Laboratories, 2005)
The inducer is a very small booster pump, lifting the suction pressure to a sufficient level for the main conventional impeller. By adding the inducer to high speed centrifugal pumps, NPSHr can be reduced to a great extent. ...
The Use Of Asbestos-Free Materials In Static Sealing On Pumps
(Texas A&M University. Turbomachinery Laboratories, 2002)
Asbestos-free gaskets have been used to seal flanged
connections on various applications. This paper discusses the use
of a different style of gasket and details the advantages and benefits
resulting from such a change. ...
