Guidelines To Maximize Reliability And Minimize Risk In Plants Using High Pressure Process Diaphragm Pumps
(Texas A&M University. Turbomachinery Laboratories, 1999)
A Comparison Of Positive Displacement And Centrifugal Pump Applications
(Texas A&M University. Turbomachinery Laboratories, 1997)
Positive displacement and centrifugal pumps sometimes seem to inhabit different worlds. Users are generally much more familiar with one type than the other. This causes some confusion when the user’s expectations are based ...
Twenty-Three Years Operating Experience With The World's Largest Boiler Feedwater Pump
(Texas A&M University. Turbomachinery Laboratories, 1997)
On the American Electric Power system, increases in generating unit size progressed from a 225 megawatt (MW) unit to the 1300 MW units, which remain the largest supercritical coal fired electric generating units in the ...
Troubleshooting Tactics To Improve Pump Mean Time Between Repairs
(Texas A&M University. Turbomachinery Laboratories, 1997)
Most pump reliability problems are rooted in basic errors that are made in the design, application, installation, maintenance, and/or operation of pumping systems. When the final, “correct,” solution to the system problem ...
Rebuilding Process Pumps To Comply With Fugitive Emissions Standards
(Texas A&M University. Turbomachinery Laboratories, 1997)
Most states have adopted regulations that limit fugitive hydrocarbon emissions from mechanical seals in centrifugal pumps. In California, limits as low as 100 ppm have been imposed. Users are faced with few choices to meet ...
Pressure Ratings Of Mechanical Seals
(Texas A&M University. Turbomachinery Laboratories, 1997)
Although mechanical seals are widely used in many machines, there is no universally accepted system for establishing limits of pressure, temperature, and speed. As a result, manufacturers of mechanical seals may use different ...
Design And Operation Of A Nonpressurized Dual Gas Seal In Light Hydrocarbons
(Texas A&M University. Turbomachinery Laboratories, 1999)
A major producer of ethylene installed and is successfully operating a nonpressurized dual gas seal in liquid methane service. The least reliable pump in the unit was a single stage overhung centrifugal pump in demethanizer ...
Improved Mechanical Seal For High Pressure Pumps In Severe Abrasive Tailings Services
(Texas A&M University. Turbomachinery Laboratories, 1996)
The cost of high pressure gland water and increasing environmental concerns have made the use of flushless mechanical seals attractive in many slurry applications. One such application exists at Syncrude Canada Lts (SCL). ...
Field Investigation Of Bearing Housing Oil Cleanliness
(Texas A&M University. Turbomachinery Laboratories, 1996)
The service life of rolling element bearing in centrifugal chemical process pumps is an issue of increasing concern. A key factor influencing bearing service life is the condition of the bearing lubricant. Several industrial ...
Mag Drive Pumps: Why They Work - How They Fail
(Texas A&M University. Turbomachinery Laboratories, 1996)
As the use of magnetic drive pumps become more popular and sometimes demanded, knowing how to install, operate and troubleshoot mag drive pumps becomes essential. System design, purchasing, installing, and commissioning ...
