Determining The Root Causes Of Subsynchronous Instability Problems In Two Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 2003)
This paper discusses the rotordynamic instability problems experienced with two separate centrifugal compressors. While the root causes of the instabilities are very different, the analysis methodology of reconciling the ...
Seal Reliability And Performance Improvements In A Large, High Pressure, High Temperature Barrel Pump
(Texas A&M University. Turbomachinery Laboratories, 2001)
Modifications to a high-pressure, high-temperature barrel pump to increase seal reliability and throughout are discussed. The pump is in unspared hydrodewaxer (HDW) feed service. The original seal design included nonpressurized ...
Reliability and Performance Improvements to a Hydrogen Recycle Compressor
(Texas A&M University. Turbomachinery Laboratories, 2007)
API Centrifugal Compressor Oil Seals And Support Systems - Types, Selection, And Field Troubleshooting.
(Texas A&M University. Turbomachinery Laboratories, 2000)
Even though dry gas seals for centrifugal compressors are becoming more popular, knowledge and understanding of oil seals and their associated support systems are still very important. Many existing compressors still have ...
Reliability Improvements To A High Speed/High Energy Pump
(Texas A&M University. Turbomachinery Laboratories, 2007)
The paper describes the problems encountered and solutions that were implemented to improve the reliability of a high speed/high energy centrifugal pump. Two of these pumps were originally installed in 1984, with a third ...
Troubleshooting Turbomachinery Using Startup And Coastdown Vibration Data.
(Texas A&M University. Turbomachinery Laboratories, 2002)
Accurate and meaningful condition monitoring is necessary to prevent both severe equipment damage and unnecessary shutdowns. One of the most important aspects of condition monitoring is the evaluation of startup and shutdown ...
