Actual Cases

1. Turbine Monitoring in a Power Plant
   • In a large – scale power plant, the MMS6312 was installed to monitor a steam turbine. It detected a gradual increase in vibration amplitude on one of the turbine’s bearings, indicating early – stage wear. Thanks to the early detection, the maintenance team was able to replace the bearing before a major breakdown occurred, minimizing downtime and saving significant repair costs.
2. Pump Monitoring in a Petrochemical Refinery
   • In a petrochemical refinery, the MMS6312 was used to monitor a centrifugal pump. It detected an abnormal change in the pump’s vibration pattern, which was caused by a blocked impeller. The early warning allowed the operators to shut down the pump safely and clear the blockage, preventing damage to the pump and ensuring the continuous operation of the production process.
