Driving Pump Reliability Forward With Advanced Composite Wear Rings
(Texas A&M University. Turbomachinery Laboratories, 2007)
In 2003, a refinery began a program to apply advanced composite wear rings, line shaft bearings, and related components. By September 2006, the program had expanded to 61 pumps, at which point plant personnel quantified ...
Electronic Data Exchange In The Pump Industry
(Texas A&M University. Turbomachinery Laboratories, 2007)
In the pump industry, technical information is shared throughout the supply chain - among the purchasers, suppliers, engineering contractors, procurement, operations, and maintenance - playing a crucial role in the life ...
Effective Isolation Treatment Of Vertical Pumps Including Seismic Restraints
(Texas A&M University. Turbomachinery Laboratories, 2007)
Three vertical pumps at a wastewater transfer station a few miles away from the San Andreas Fault and next to an apartment building were the source of vibration and noise complaints. To attune the transmitted vibration, a ...
Contemporary Guide To Mechanical Seal Leakage
(Texas A&M University. Turbomachinery Laboratories, 2009)
The mechanical seal is a critical component in many mature industrial processes such as flue gas desulphurization, crude oil transport and refining, electricity production, and pharmaceutical manufacturing. A “critical ...
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 ...
