Predictive Maintenance

Hi Experts

Need SAP Best Practices / scenarios for Predictive maintenance with flows.

Thanks & Regards

Hi,

Predictive maintenance, as implied, is to look into future and anticipating the break downs. This type of preventive maintenance came into play from TPM (Total Productive Maintenance), which envisages 100% availability of equipment.

Take the following example to understand the procedures:

The manufacturer recommends replacement of a rotating component- a bearing for example, to be replaced every 1000 operating hours. By adapting proper preventive maintenance techniques, there is a possibility that the bearing has not worn out at 1000 operating hours, as predicted by manufacturer, who would have taken the avarage working environment of the equipment.

Here predictive measures come into play, which have been made available by latest innovations and the associated technical standards, which specify new tolerances for rotating machinery, to ascertain the health of the component.

Hence Vibration analysis, Fluid analysis -to name a few, came into play.

Based on the result, and experience, the change frequency of 1000 operating hours will be extended by say, 250 hours, after which the required analysis is carried out once again.

Subsequent analysis may determine the life of the bearing to say, 1750 operating hours.Up to this stage, predictive maintenance rules.

Henceforth, condition based maintenance takes over, which will stipulate a vibration analysis at 1500 hours and a change of component at 1750 hours.

Ultimately, the equipment availability is increased, un expected break downs are avoided and maintenance cost comes down.

By the above example, it is clear that the predictive maintenance precedes condition based maintenance.

It is up to the consultant to decide the method of adaption to implement the above sequences in SAP.
