“Signatures”
Spot Signs of Wear. J. C. Wachel, Editorial Article, Chemical
Week, July 19, 1972, p. 33 .
High-frequency vibration patterns in rotating machinery reveal potential
trouble in time to correct it before damage is done. Plant managers
interested in getting early warning of potential failure of high
speed rotating machinery can choose from a growing list of consulting
firms offering sophisticated techniques for analyzing high-frequency
vibrations.
Next month,
at the American Institute of Chemical Engineers meeting in Minneapolis,
Southwest Research Institute (SwRI) will explain the machinery
analysis program it is using to extend the onstream time of methanol
plants. A few weeks later, in Cleveland, consultants with Dow
Industrial Service (Pleasant Hill, Calif.) will tell the American
Society for Non-Destructive Testing about their methods of predictive
analysis.
Boeing Co.
also offers a service to detect vibrations in machinery with special
sensing devices (CW, May 10, p. 29), and several other firms have
similar programs.
