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 ...
Table of Contents for the Proceedings of the 26th Turbomachinery Symposium
(Texas A&M University. Turbomachinery Laboratories, 1997)
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 ...
Redesign Of The Last Two Stages Of A Mechanical Drive Steam Turbine.
(Texas A&M University. Turbomachinery Laboratories, 1998)
A six stage mechanical drive steam turbine rated at 13,300 hp
was installed at a petroleum facility in Texas to drive a multistage
centrifugal compressor used in recycle gas service on a high
pressure hydrogen cracker. ...
Guidelines For Specifying And Evaluating New And Rerated Multistage Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1998)
Refineries, petrochemical companies, and gas processors are
continually trying to increase plant production while budgets are
getting tighter. Rerating process centrifugal compressors has
become an ever-increasing trend ...
Gas Turbine Blade Failures - Causes, Avoidance, And Troubleshooting.
(Texas A&M University. Turbomachinery Laboratories, 1998)
With blading problems accounting for as many as 42 percent of
the failures in gas turbines (Allianz, 1 978) and with its severe
effect on plant availability, there is a pressing need for a unified
treatment of the causes, ...
Gas Turbine Power Augmentation By Fogging Of Inlet Air.
(Texas A&M University. Turbomachinery Laboratories, 1999)
Gas turbine output is a strong function of the ambient air temperature with power output dropping by 0.3 percent to 0.5 percent for every 1 F rise in ambient temperature. While this characteristic is inherent in any gas ...
