Leybold’s Online Sound Checks Can Determine Vacuum Pump Condition

May 11, 2021
Leybold offers online sound checks for vacuum pumps.

With this online tool, users receive immediate feedback regarding the condition of their vacuum pumps.

Leybold says it is taking a big step toward the digitalization of its product line with an online sound check for vacuum pumps available on its website. With this free tool, users receive immediate feedback regarding the condition of their vacuum pumps.

Users simply record a sequence of their pump's sound with their smartphone or tablet directly at sound.leybold.com or upload the sound file. The sound analysis is then used to determine whether the pump is running properly or if service is due. This feature initially applies to the Leybold Varodry and Novadry oil-free screw vacuum pumps but will be extended to other pumps in the future.

Using an intelligent test algorithm, Leybold draws upon its extensive vacuum expertise. "Through our many years of experience, we now know exactly to what extent a pump's operating noise indicates its condition," explains Dr. Sina Forster, the project manager heading up this project for Leybold.

While the human ear can't perceive various pump noises above a certain frequency, the app can quickly and objectively detect the condition of the gears and/or bearings. If deviations occur, they're detected immediately by the test algorithm, and the probability of an error is then displayed. "From an acoustic analysis of the vacuum pump, we can come up with specific recommendations and schedules for service and maintenance work, such as belt changes," explains Dr. Forster.
