PREDICITIVE MAINTENANCE AND INSPECTION AIRBORNE ULTRASOUND TECHNOLOGY

摘要

Airborne ultrasound can be considered an ideal integrating technology in that these instruments can stand alone to detect a variety of potential problems or they can be used with other PDM technologies such as vibration and infrared. Usually portable, these instruments detect leaks in both pressurized gas systems and vacuum systems and related equipment such as tanks, pipes, heat exchangers, valves and steam traps. Additional applications include inspection of high voltage apparatus for corona, arcing and tracking. They are used to trend bearing failure as well as to detect conditions such as lack of lubrication and rubbing. A brief overview of the technology, its applications, and suggested inspection techniques are explained.
