Failure Of Turbomachinery Components.
(Texas A&M University. Turbomachinery Laboratories, 1985)
The analysis of turbomachinery failures is a highly specialized field requiring a detailed understanding of superalloy metallurgy, moderate and high temperature failure mechanisms and an appreciation of the stresses, ...
Rotordynamic Stability - A Simplified Approach.
(Texas A&M University. Turbomachinery Laboratories, 1985)
Straightforward mechanics are used to give a physical understanding of the important parameters involved in rotor dynamic instability. A concise analysis procedure is proposed for assembling available information into a ...
Practical Applications Of Rotordyanmics, Bearing Design, Mechanical Analysis, And Vibration Diagnostics To Design Problems of Rotating Machinery in Operation
(Texas A&M University. Turbomachinery Laboratories, 1989)
A large majority of today's existing high performance rotating machinery in operation was manufactured and installed long before the advent of powerful design tools in the complex areas of rotor system dynamics and stability ...
Heavy Shell Castings Design/Operation And Repairs Criteria.
(Texas A&M University. Turbomachinery Laboratories, 1989)
Unless the utility industry is prepared as a whole to commit a very large dollar amount to the purchase of new heavy wall castings for turbine casings and valve chests, the use of the art of repair for existing castings ...
Reapplication Of Turbomachinery.
(Texas A&M University. Turbomachinery Laboratories, 1989)
The reapplication of equipment can be attractive and rewarding when the proper situation warrants. The main factors that encourage consideration of this path can include simple economics, convenience, or possibly a more ...
Solid Couplings With Flexible Intermediate Shafts For High Speed Turbocompressor Trains.
(Texas A&M University. Turbomachinery Laboratories, 1989)
The design and application of solid couplings combined with flexible quill shafts for high speed turbocompressors are presented. Solid couplings are rigid in the axial direction. They transmit any residual thrust from one ...
Hydraulically Fitted Hubs, Theory And Practice
(Texas A&M University. Gas Turbine Laboratories, 1980)
The transmission of torque from a shaft to a hub can be efficiently accomplished through the use of friction. The advantages of this system over a keyed connection are: (1) the significant reduction of stress concentrations ...
Dynamic Balancing
(Texas A&M University. Gas Turbine Laboratories, 1980)
Unbalance has been found to be one of the most common causes of machinery vibration, present to some degree on nearly all rotating machines. This paper is presented to provide essential information needed to solve the ...
Failure Analysis And Repair Techniques For Turbomachinery Gears
(Texas A&M University. Gas Turbine Laboratories, 1980)
This paper covers the use of gears in turbomachinery applications. It reviews the contents of the American Gear Manufacturers Association (AGMA) and American Petroleum Institute (API) standards. During the course of an ...
How To Install Maintainable Bearing Temperature Sensors
(Texas A&M University. Turbomachinery Laboratories, 1981)
This paper covers techniques for retrofitting turbomachinery to accept "stab-in" type thermocouples for bearing temperature monitoring. The objectives of bearing temperature monitoring and shutdown systems are to (1) avoid ...
