Installation Tools for Hydraulically Fitted Coupling Hubs - Precautions and Design Requirements
(Texas A&M University. Turbomachinery Laboratories, 1997)
The tools used to install hydraulically fitted hubs need to be as carefully designed and manufactured as the couplings themselves. The authors describe an installation of coupling hubs on upgraded machines where tools that ...
Cost Effective Re-Engineering Of A Propylene Compressor String.
(Texas A&M University. Turbomachinery Laboratories, 1997)
The discussed rerate method will provide users of turbomachinery with a new, cost/leadtime saving approach to plant upgrades. Although rerates of existing turbomachinery are common, this approach is unique in that the ...
An Assessment Of The Forces Acting Upon A Centrifugal Impeller Using Full Load, Full Pressure Hydrocarbon Testing.
(Texas A&M University. Turbomachinery Laboratories, 1997)
Although turbocompressors have been designed, built, and used in increasingly stringent conditions for more than 80 years, the turbomachinery industry, like all comparable industries, can only design and manufacture its ...
Understanding And Preventing Steam Turbine Overspeeds.
(Texas A&M University. Turbomachinery Laboratories, 1997)
Destructive overspeeding of steam turbines due to poor component design, inadequate maintenance, and improper operating practices are all too common. The total cost of a turbine runaway can run into the millions of dollars ...
Stress Evaluation In High Speed, Rotating Machinery With The Lcr Ultrasonic Technique.
(Texas A&M University. Turbomachinery Laboratories, 1997)
The LcR ultrasonic technique is ideally suited for stress
measurement, since it is a bulk longitudinal wave that propagates
just underneath the surface of the item being inspected.
Additionally, it is most sensitive to ...
Rerate Of Centrifugal Process Compressors - Wider Impellers Or Higher Speed Or Suction Side Boosting?.
(Texas A&M University. Turbomachinery Laboratories, 1997)
Impeller exchange, speed increase, and supercharging are the
usual means to increase the capacity of existing industrial turbocompressors
of the single shaft type. Replacing an existing rotor by
a new one with wider ...
Subtracting Residual Unbalance For Improved Test Stand Vibration Correlation.
(Texas A&M University. Turbomachinery Laboratories, 1997)
The importance of correlating rotordynamic analytical results to actual test data has become extremely important in recent years. Many user specifications require the verification of vendor generated analytical results in ...
High Speed Electric Drive Applications - An Overview.
(Texas A&M University. Turbomachinery Laboratories, 1997)
Worldwide, current technology has opened a wide range of new applications for electric motors, many of which have traditionally employed mechanical (turbine) drivers. While the use of electric motors for these high speed ...
Steam Turbine Risk Assessment - A Tool To Assist In Optimizing Inspection And Overhauls Of Industrial Steam Turbines.
(Texas A&M University. Turbomachinery Laboratories, 1997)
There are currently no-or at best, very limited-industry guidelines or requirements on which to quantify the risk associated with turbine inspection intervals. Insurance industry data indicate that steam turbines are a ...
Flow-Induced Turbocomprosser And Piping Noise And Vibration Problems - Identification, Diagnosis, And Solution.
(Texas A&M University. Turbomachinery Laboratories, 1997)
The problem of flow-induced noise and vibration in turbocompressors and piping systems is complex and not readily understood. These problems are difficult to identify and solutions may not be obvious. A working knowledge ...
