Acoustics In Pumping Systems
(Texas A&M University. Turbomachinery Laboratories, 2009)
This tutorial will explain the pumping system speed of sounds concept (how to account for acoustic velocity changes due to pipe wall flexibility and liquid properties), the definition of quarter-wave, half-wave, and higher ...
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 Concept In Mechanical Seal Cooling - The Integral Heat Sink
(Texas A&M University. Turbomachinery Laboratories, 2005)
Thermally induced failures have long since plagued mechanical seal users. Over the years these failures have led to the development of different flush plan and seal design features that are used to increase heat transfer ...
Practical Design Against Pump Pulsations
(Texas A&M University. Turbomachinery Laboratories, 2005)
One of the foremost concerns facing pump users today is that of pulsation problems in their piping systems and manifolds. In cases where a fluid excitation is coincident with both an acoustic resonance and a mechanical ...
Material Selection For Mechanical Seals
(Texas A&M University. Turbomachinery Laboratories, 2005)
Mechanical seals are used throughout industry to minimize or eliminate leakage in centrifugal pumps, mixers, and other rotating equipment. The ability of a mechanical seal to meet its performance objectives depends upon a ...
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 ...
Short Courses for the Proceedings of the 22nd International Pump Users Symposium
