Present Instrumentation And Future Trends In Real Time Analysis Equipment
(Texas A&M University. Gas Turbine Laboratories, 1972)
In the past instrumentation available to the diagnostician for analysis of machinery problems was limited to swept narrowband filter systems and, less important, parallel narrowband filter systems. Although useful for ...
Lubrication Systems For Turbomachinery
(Texas A&M University. Gas Turbine Laboratories, 1978)
A lubrication system for turbomachinery of significant size generally consists of a reservoir, pump, filter, cooler, piping and controls. Experience through the years has indicated design criteria required to minimize ...
A New Vibration Criteria For High Speed Large Capacity Turbomachinery
(Texas A&M University. Gas Turbine Laboratories, 1979)
This paper presents the development and analysis of new critical speed criteria. The critical speed has been defined as the resonant speed of the rotor bearing system at which large response amplitudes can occur. However, ...
Couplings - A User's Point Of View
(Texas A&M University. Gas Turbine Laboratories, 1979)
Couplings are one of the critical elements in a turbomachinery system. Malfunctions and failures results in significant outage time that, in most cases, is very costly to the user. This paper will deal with the application ...
Effects Of Fluid-Filled Clearance Spaces On Centrifugal Pump And Submerged Motorvibrations
(Texas A&M University. Gas Turbine Laboratories, 1979)
Annular clearance spaces, such as impeller wearing rings, inter0stage bushes and balance drums in centrifugal pumps, or the fluid-filled clearance around the armature of the submerged motor, at a first glance present the ...
Some Metallurgical Considerations In Centrifugal Compressors
(Texas A&M University. Gas Turbine Laboratories, 1973)
Consideration of the materials for use in rotating machinery must begin with careful study and appraisal of expected operating conditions. In the discussion which follows, attention is concentrated on centrifugal compressors, ...
Repair Techniques For Rotor And Case Damage
(Texas A&M University. Gas Turbine Laboratories, 1973)
To properly install, profitably operate, and economically maintain high speed rotating machinery requires considerable skill, judgment, and experience. Excellent engineering references covering the mechanical design and ...
Fluid Film Bearing Design Considerations
(Texas A&M University. Gas Turbine Laboratories, 1972)
The basic and practical design concepts of fluid film bearings as applied to turbomachinery will be discussed. The discussion will cover specific applications that are representative of a wide range of conditions that can ...
Centrifugal Compressor Operation And Maintenance
(Texas A&M University. Gas Turbine Laboratories, 1972)
The operation and maintenance of centrifugal compressors varies considerably depending upon the size, speed, horsepower, and type of driver. Typical centrifugal compressors vary from high speed, low flow applications to ...
Application Of Spectrum Analysis To Onstream Condition Monitoring And Malfunction Diagnosis Of Process Machinery
(Texas A&M University. Gas Turbine Laboratories, 1972)
Recent experiences with frequency spectrum analysis for onstream evaluation of mechanical performance are reviewed from a user's standpoint. Current practices of transducer selection and positioning, data acquisition and ...
