(Texas A&M University. Turbomachinery Laboratories, 1989)
Setting Vibration Criteria For Turbomachinery.
(Texas A&M University. Turbomachinery Laboratories, 1989)
Vibration of a journal within a fluid film bearing produces a dynamic load on the babbitted bearing surfaces. A rational vibration criterion can be based on a consistent magnitude of this dynamic load among widely different ...
Vibration Monitoring Of Turbomachinery.
(Texas A&M University. Turbomachinery Laboratories, 1990)
The overall concept of vibration monitoring is presented based upon theory and the practical constraints of machinery construction, transducer characteristics and the cost/benefit ratio of available systems. General features ...
Gas Turbine Control Systems Incorporating Condition Monitoring And Fault Tolerance.
(Texas A&M University. Turbomachinery Laboratories, 1990)
Novel concepts in gas turbine control technology incorporating condition monitoring and fault tolerance are described. Concerns with fault tolerance, system reliability, and users functionalities are discussed. The importance ...
An Independent Refiner's Approach - Practical Solutions To Complex Gear Problems.
(Texas A&M University. Turbomachinery Laboratories, 1990)
Numerous failures and near failures spanning the last quarter century have occurred on a 4000 hp, single induction, double helical speed increaser in hydrogen recycle service. A persistent and unexplainable wear pattern, ...
Specifying, Manufacturing, And Testing A Cryogenic Turboexpander Magnetic Bearing System.
(Texas A&M University. Turbomachinery Laboratories, 1991)
The state-of-the-art magnetic bearing system, as it exists today, has several unique characteristics which tend to make certain applications of this technology more favorable than others. One application which seems quite ...
Maximizing Compressor Efficiency While Maintaining Reliability.
(Texas A&M University. Turbomachinery Laboratories, 1989)
The natural gas and chemical processing industries have historically and necessarily demanded high reliability from their centrifugal compressors, which has led to a significant emphasis on field experience of designs. ...
Using A "Sound Tube" To Measure Noise Of Structural Sources In High Background Noise Environments
(Texas A&M University. Gas Turbine Laboratories, 1980)
Described in this paper is a device referred to as a soundtube, which has been designed to accurately measure only the normal component of the surface velocity of a vibrating structural noise source. Both laboratory and ...
Submerged Arc Weld Restoration Of Steam Turbine Rotors Using Specialized Welding Techniques.
(Texas A&M University. Turbomachinery Laboratories, 1991)
In the past 10 years, there have been significant gains made in the repair of steam turbine rotors by the use of welding. This has been the result of improvements in several areas dealing with materials, engineering analysis, ...
Standardized Integrally Geared Turbomachines - Tailor Made For The Process Industry.
(Texas A&M University. Turbomachinery Laboratories, 1991)
For more than 40 years, integrally geared centrifugal compressors have been in use worldwide, in the plant air sector first, and increasingly in the process industry. Apart from reliability, efficiency and operating range, ...
