Using A "Sound Tube" To Measure Noise Of Structural Sources In High Background Noise Environments
(Texas A&M University. Gas Turbine Laboratories, 1980)
Described in this paper is a device referred to as a soundtube, which has been designed to accurately measure only the normal component of the surface velocity of a vibrating structural noise source. Both laboratory and ...
Reverse-Indicator Alignment And Related Subjects
(Texas A&M University. Gas Turbine Laboratories, 1980)
This paper is a discussion of reverse-indicator measurement and other alignment subjects. The basic steps in doing an alignment job and some of the tooling that can be used will be described.
Unique Fan Vibration Problems: Their Causes And Solutions
(Texas A&M University. Gas Turbine Laboratories, 1980)
Operating requirements for new fans demand that greater attention be given to the design of the total installation including everything from the foundation to the ducts. Rotor dynamic analysis without adequate consideration ...
Instrumented Couplings: The What, The Why And The How Of The Indikon Hot-Alignment Measuring System
(Texas A&M University. Gas Turbine Laboratories, 1980)
The Analysis Of Surge
(Texas A&M University. Gas Turbine Laboratories, 1980)
Recently, considerable attention has been given to the phenomenon of surge in compressors and pumps. Typically, the model under study is a Helmholtz resonator and driver where the flow in the delivery duct to the resonator ...
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 ...
Total Alignment Can Reduce Maintenance And Increase Reliability
(Texas A&M University. Gas Turbine Laboratories, 1980)
There are several acceptable alignment methods presently available. Despite their diversity, one common thread of agreement is noted. That is, maximum machine life and optimum runs will not be attained unless the machines’ ...
Geothermal Power And Problems
(Texas A&M University. Gas Turbine Laboratories, 1980)
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 ...
