Case Study - Increasing The System Flow In An Existing Sump
(Texas A&M University. Turbomachinery Laboratories, 1999)
The status of our country’s infrastructure is a topic that has been discussed at length in the past few years. Aging roads and bridges are no longer capable of meeting the demands of a growing population. They suffer either ...
Pump Life-Cycles And The Internet Utilizing Technology To Improve Pump Reliability
(Texas A&M University. Turbomachinery Laboratories, 1997)
Information technology, specifically computer mediated communication (CMC), will revolutionize the pump industry, from selection through installation, operation, and maintenance. There will be winners and losers. It will ...
The Application Of Computer Simulation And Real-Time Monitoring To Minimize The Pressure Pulsations In Complex Pumping Systems
(Texas A&M University. Turbomachinery Laboratories, 1997)
Chemical and process plants usually contain numerous valves and pumps in a complex network of pipe runs. Plant design and pump selection are usually based on steady state design conditions. However, the opening or closing ...
Replacement Of The Boiler Feedpumps During The Retrofit Of The 500 Mw Units At A German Power Station
(Texas A&M University. Turbomachinery Laboratories, 1997)
The Janschwalde Power Station consists of six 500 MW units that were commissioned between 1981 and 1989. These units, which were equipped with turbo feedpumps manufactured in Russia, had an average efficiency of only 78 ...
Tutorial On Special Purpose Pumps-Pitot; Progressing Cavity; Air Operated Diaphragm; And Hydraulically Actuated Diaphragm
(Texas A&M University. Turbomachinery Laboratories, 1997)
Double Gas Seal With Coplanar Coaxial Rayleigh Pad Faces For Pump Sealing Applications
(Texas A&M University. Turbomachinery Laboratories, 1999)
There has been a rapid growth in the application of noncontacting double seals with a gas buffer fluid to pump sealing. The advantages of such a sealing arrangement are:
• There is no liquid buffer fluid to maintain or ...
Finding And Eliminating Chronic Pump Failures
(Texas A&M University. Turbomachinery Laboratories, 1999)
A Gulf Coast refinery decided to actively address rising pump maintenance costs and risk of production losses by using accumulated failure data and maintenance costs to identify bad actor pumps, then solving the problems ...
Development Of A Twin Hybrid Noncontacting Gas Seal And Its Application To Process Pumps
(Texas A&M University. Turbomachinery Laboratories, 1999)
In this paper, an innovative approach of applying gas-lubricated, noncontacting sealing technology to process pumps is presented, in which a novel “twin hybrid” design is incorporated to address the issues of gas seal ...
Component Balance For Centrifugal Pumps - Effects Of Product Design, Balance Machine Tooling, And The Balancing Process On Balancing Repeatability
(Texas A&M University. Turbomachinery Laboratories, 1999)
Balancing of pump rotating components, especially impellers, is common practice. The purpose of this effort was to determine the proper design of pump components and balance arbors, create appropriate procedures, and ...
Surge Detection In An Industrial Axial Flow Compressor.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Compressor surge can be a disruptive and potentially destructive phenomena in turbocompressors. A surge detection scheme utilized in shop and field testing of a 29,600 hp (22 MW) industrial axial compressor is described. ...
