Case Study: Preventive maintenance through fan monitoring to avoid failure stoppage of rotating machinery.

basic information

■Case Overview A case study on the introduction of preventive maintenance in a chemical manufacturer. Prior to implementation, challenges included difficulties in diagnosing the vibration of rotating machinery bearings due to inverter noise. This time, a rotating machinery fault prediction monitoring system that addresses inverter carrier noise removal was introduced, enabling vibration diagnosis. It was estimated that by avoiding failure-related downtime, losses could be mitigated by 30 to 70 million yen annually.

■Overview of Implementation Case Implementing Company: Fan monitoring for a chemical manufacturer Implemented Product: Rotating Machinery Fault Prediction Monitoring System Wiserot <Challenges Before Implementation> In traditional rotating machinery vibration diagnostics, it was sometimes impossible to diagnose the vibrations of the bearings due to the influence of carrier vibration noise from the inverter. <Effects of Implementation> By cutting out the carrier vibration noise from the inverter, it became possible to diagnose the vibrations of the bearings. This made it possible to avoid failure stoppages, achieving an estimated annual loss prevention of 30 to 70 million yen.
