Lighting Survey Results at the Langford Architecture Center and Estimated Savings by Delamping
(Energy Systems Laboratory (http://esl.tamu.edu), Texas A&M University, 1997)
This report presents the results of a survey conducted to measure the illuminance levels in all rooms in the Langford Architecture Center buildings. The purpose of this survey was to investigate which rooms are over ...
Analysis of the HVAC System at the Willow Branch Intermediate School
(Energy Systems Laboratory (http://esl.tamu.edu), Texas A&M UniversityDepartment of Mechanical Engineering, Texas A&M University, 1997)
This report presents an analysis of the HVAC system at the Willow Branch Intermediate School for the MEEN 685 class project. The school is located at College Station, Texas. A portion of the school belonged to Oakwood ...
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 ...
Subtracting Residual Unbalance For Improved Test Stand Vibration Correlation.
(Texas A&M University. Turbomachinery Laboratories, 1997)
The importance of correlating rotordynamic analytical results to actual test data has become extremely important in recent years. Many user specifications require the verification of vendor generated analytical results in ...
High Speed Electric Drive Applications - An Overview.
(Texas A&M University. Turbomachinery Laboratories, 1997)
Worldwide, current technology has opened a wide range of new applications for electric motors, many of which have traditionally employed mechanical (turbine) drivers. While the use of electric motors for these high speed ...
Steam Turbine Risk Assessment - A Tool To Assist In Optimizing Inspection And Overhauls Of Industrial Steam Turbines.
(Texas A&M University. Turbomachinery Laboratories, 1997)
There are currently no-or at best, very limited-industry guidelines or requirements on which to quantify the risk associated with turbine inspection intervals. Insurance industry data indicate that steam turbines are a ...
