Design Audits.
(Texas A&M University. Turbomachinery Laboratories, 1986)
Dynamic design audits of machinery can identify potential problems before the machine is manufactured, thus preventing costly project delays and downtime. The types of audits that should be performed are discussed and ...
Effects Of High Pressure Oil Seals On The Rotordynamics Response Of Centrifugal Compressores.
(Texas A&M University. Turbomachinery Laboratories, 1986)
The influence of high pressure bushing-type oil seals on the rotordynamic characteristics of a centrifugal gas compressor, which compresses hydrogen from 1700 psi to 1800 psi is discussed. The compressor rotor is driven ...
Detection of Rotor Cracks
(Texas A&M University. Turbomachinery Laboratories, 1986)
The method of detection of rotor cracks by vibration monitoring is outlined. Various mechanisms stimulating cracks are discussed. Vibration measuring instrumentation and diagnostic methodology for early detection of rotor ...
Retrofit Installation Of A Boiler Feed Pump Hydraulic Coupling.
(Texas A&M University. Turbomachinery Laboratories, 1986)
The application of main turbine-generator shaft drive for boiler feed pumps is generally accepted as a method to increase unit efficiency. The use of shaft drive eliminates the power requirement of an auxiliary motor or ...
Development And Implementation Of An Expert System To Diagnose Motor Vibration Problems.
(Texas A&M University. Turbomachinery Laboratories, 1986)
An expert system, TurboExpert, has been developed to diagnose vibration problems dealing with rotating equipment.
Starting with a small inexpensive expert system shell, the program was expanded to include many characteristics ...
Oil Seal Dynamics: Considerations For Analysis Of Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1986)
Oil seals are used in many industrial compressor designs where positive control of the process gas is essential. Consideration of the influence of these seals is necessary for proper design evaluation. The oil seals can ...
Radial And Thrust Bearing Practices With Case Histories.
(Texas A&M University. Turbomachinery Laboratories, 1985)
Case histories for 13 selected bearing design conversions for specific end results are presented. They were selected out of a group of bearing designs over a 25 year span to give a varied array of non-repetitive case ...
A Practical Approach To Understanding Steels, Their Alloying, Heat Treatment And Surface Hardening.
(Texas A&M University. Turbomachinery Laboratories, 1985)
The greatest tonnage of engineering materials used in the world are steels. Therefore, it is most helpful, and in many cases mandatory, that those who either design, fabricate or maintain components constructed of steel ...
Subsynchronous Vibration Problems In High-Speed, Multistage Centrifugal Pumps.
(Texas A&M University. Turbomachinery Laboratories, 1985)
Subsynchronous vibration problems were experienced on two reactor charge pumps during on-site commissioning, which led to large whirl amplitudes, making the units automatically trip. A number of possible mechanisms of ...
Review Of Fundamental Two Pole Induction Motor Mechanics.
(Texas A&M University. Turbomachinery Laboratories, 1985)
An introduction to two pole motor mechanics is presented, with the goal of promoting an understanding of normal and abnormal vibration sources to assist in the diagnosis of the field problems of such motors. Motor force ...
