The foundation of success

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

• sound.leybold.com – the intelligent service planning tool

• Sound Analyzer

Available initially for VARODRY and NOVADRY
Simply record a sequence of your pump's sound with your 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.

The operating noise reflects the pump's condition
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.

Concrete Service Recommendations
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. 

Business management advantage
This sound analysis represents a major economic advantage and encourages compliance with suggested service intervals. Based on the test results, customers can contact Leybold Service directly and transmit the sound data for a more detailed analysis. Depending on the condition of the vacuum pump, it can be determined if service is due without the need for a service call. As such, repair and maintenance work, in addition to downtimes for the entire system, can be anticipated and planned.

The advantages at a glance:

• No downloads or installations required

• Perform the sound analysis with five clicks at sound.leybold.com

• Results available within ten seconds

• Condition of the bearings can be recorded

• Condition of the gears and hence the belt can be recorded.
