Understanding The Vibration Forces In Induction Motors.
(Texas A&M University. Turbomachinery Laboratories, 1990)
Squirrel cage induction motors have been used extensively in industry for over 50 years. While it appears that vibration problems are more pronounced nowadays, certain basic construction features have always existed and ...
Magnetic Bearings And Dry Gas Seals - A Process Compressor Application.
(Texas A&M University. Turbomachinery Laboratories, 1990)
The design considerations and features along with manufacturing and operating experiences encountered on a multistage centrifugal process compressor incorporating a dry gas seal and active magnetic bearings immersed in the ...
Romex - An Expert System Testbed For Turbomachinery Diagnostics.
(Texas A&M University. Turbomachinery Laboratories, 1990)
A rule based system developed for vibration oriented diagnosis of turbomachinery for fault identification and for predictive maintenance is described. The system is implemented in a PC based PROLOG environment, with the ...
Piping Vibration Analysis.
(Texas A&M University. Turbomachinery Laboratories, 1990)
Excessive piping vibrations are a major cause of machinery downtime, leaks, fatigue failures, high noise, fires, and explosions in refineries and petrochemical plants. Excessive vibration levels usually occur when a ...
Energy Recovery In A Gas Distribution Station By Combination Of Expanders With Planetary Gear And Optimum Single Valve Control.
(Texas A&M University. Turbomachinery Laboratories, 1990)
The prevailing use of expansion gases in distribution stations can be economically replaced by the application of turbo expanders. The advantage of turbine impulse wheels is that they have high efficiencies, even at very ...
Online Ultrasonic Monitoring Of Bearing Wear.
(Texas A&M University. Turbomachinery Laboratories, 1990)
Unpredicted bearing failures continue to plague industry with forced outages. As a result of these outages, many industries have attempted prevention by unnecessary inspections and premature bearing replacement. This work ...
