Gear couplings can produce large static forces and moments that can affect the vibrations of turbomachinery, even with nearly perfect alignment. Research, testing and case histories have verified this theory and are reported. ...

Flexible couplings are a vital part of a power transmission system. What type is selected, how much the coupling costs, and how much effort one spends on selecting a coupling and determining how it interacts with a system ...

Geothermal energy is becoming an increasingly important source of electrical power in today's world. Presented here is a review of the world wide geothermal situation and the development of "The Geysers" geothermal resource ...

Leakage from static joints has been found to be a major contributor of emissions in many plants. With the collaboration from the world’s leading gasket manufacturers, the Gasket Division of the Fluid Sealing Association ...

High temperature services are on of the more challenging applications for mechanical seals. Herein are recommendations and guidelines for selection and application of dual metal bellows seals for use in high temperature ...

Performance testing of centrifugal compressors in the field is generally a compromise at best, and shop testing before delivery to the site is usually preferred. There are circumstances that dictate or suggest that the ...

The first task in extending the life of gas turbine parts is to develop meaningful life trend and aging characteristics for each material. Components that have reached their critical life limit can then be hot isostatic ...

Steam turbines may be rerated, reapplied, or modified to meet several specific goals. This tutorial will review possible reasons for these changes, including optimizing performance, improving reliability, reducing maintenance ...
