Digital fingerprint enables targeted troubleshooting
Darmstadt, October 2016 – In many production processes, balancing machines are essential for quality assurance. If they do not work accurately or fail to work at all, this can lead to costly delays. This is why Schenck RoTec has developed the fingerprint. This digital fingerprint refers to the individual vibration pattern of a balancing system. It enables predictive maintenance and quick troubleshooting in case of malfunction.
The existing CAB (computer aided balancing) measuring technology and vibration sensors are used to assess the machine's condition and analyze any faults. The fingerprint has proved its worth over the last few years – Schenck RoTec's analysis tool now supports almost 500 machines worldwide.
In practice, it works as follows: Prior to delivery and during the initial commissioning, the Schenck RoTec service engineers record the initial vibration pattern of the new machine ready for operation. This machine fingerprint with its specific properties is then archived and serves as a basis for comparison with future fingerprints to determine any deviations.
Avoiding unscheduled downtime
Regular fingerprints not only enable fast and targeted troubleshooting but also support machine monitoring. For the purpose of predictive maintenance, additional fingerprints of the machine are taken on a regular basis and compared with the archived data. This allows users to draw conclusions on the condition of the machine, and to accurately identify any wear, faults or damage. Potential problems can thus be detected at an early stage, and repairs can be scheduled accordingly. Unexpected outages can be largely avoided, which considerably improves the efficiency of the system.
If a fault occurs, the fingerprint facilitates troubleshooting. The service engineer records the current vibration pattern of the machine on site and sends it to the Schenck RoTec service center in Darmstadt, which immediately provides a current status report following detailed analysis. The engineer can search for the causes systematically, complete the task more quickly, and ensure that the machine is up and running again in no time.
The active use of the machine fingerprint requires a measuring device of the CAB900 series with the current software version as well as a corresponding maintenance contract.
