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 ...
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, ...
Harmonic Free Magnetic (FCMA) Soft Starters For Large Capacity High Voltage Induction And Synchronous Motors Driving Pumps And Compressors
(Texas A&M University. Turbomachinery Laboratories, 2005)
Most of the water supply schemes use electrical power in large quantities. As such, optimization is needed for reducing life cycle cost of the entire establishment in terms of capital cost, minimum downtime, and maximum ...
Improvements In Bearing Life Using New Sealing Technology
(Texas A&M University. Turbomachinery Laboratories, 2005)
As many as 91 percent of all rolling element bearings fail to achieve their calculated theoretical lifetimes. One of the primary reasons for this failure is contamination of the lubricants. Past practice for protecting ...
A New Unique High Pressure Pump System
(Texas A&M University. Turbomachinery Laboratories, 2005)
The combination of a 16 inch Pitot tube pump with a switched reluctance motor represents a significant development in the field of high-pressure pumping. A field proven Pitot tube pump design has been mechanically integrated ...
Impeller Rerate To Reduce Hydraulically Generated Vibration
(Texas A&M University. Turbomachinery Laboratories, 2005)
The vibration of centrifugal pumps, running at both best efficiency point (BEP) and at low flow, is of interest to both pump designers and users. This vibration is responsible for the poor seal and bearing life and reduced ...
