Maintenance frequency with varaible factors

Hi Experts,

    I'm wondering for the solution of a scenario, where we have few Motors, which can be used in two different situations.

1. At full peak load -- > When demand is high the motor runs at full load capacity and during this Preventive maintenance is required after 15 days

2. At partial load -- > During off peak season, based on load the speed can be controlled by drive and motor runs at partial load capacity. during this Prev. Maint. is required after 45 Days.

Any idea , how the maintenance plans can be mapped in this scenario ? I was planning to map it via Multiple counter . One for peak and another for off peak. But don't know how to create order one at a time. How to get system know, when the motor is running on Partial and when on full load.

Do i need to make some custom development for this??

Similarly, there's a case of pipeline, where sometimes the Water flows (Maintenance freq= 3 month) while sometime Acid flows through the same pipe (Maintenance Freq= 15 Days). How to get the plan map for this ??

Please provide some inputs ..

Hii Dennis,

Just a thought dont know whether it will be feasible or useful in this case...

Plan counter based preventive maintenance on the production/process order quantity.

During peak period order quantity will be more as compared to off peak period order quantity.

And after confirmation of order a Preventive maintenance order should be created.

The above scenario suits perfectly in case of PRT equipments, hope this can give some solution or a point to think this way.

Hello Dennis,


On your behalf, I will try to make it clear that in both cases, the regulation (peak / off peak loads) is not manual, but is automatic depending upon the demand, sensed through devices like sensors. If this statement is true, confirm. If it is not, and the regulation is manual, then clarify what is the cycle period of these manual settings. Means how many days continuously in peak setting and off-peak setting?

With the above info, probability for better replies would increase.

Dear Jogeswara, Thanks for your reply

For better understanding, i would like to quote the Example of Lathe machine.

User operate the lathe machine based on the demand of the end product. In peak time, usage is full while in off peak time,usage is partial.

All load transfer is manual (no sensing device). When user see the capacity requirement is high , he deploy another machine, in case it's not catered by one machine. so based on the work load, manually the load gets transferred to attached motor.

Also reg. your second quarry, there's no such fixed no. of days for peak/off peak loading. It depends on demand from market. Sometimes sudden order rush, then it need to be fulfilled by operating all machine in full capacity and loading. Else, it'll be operated on partial loads.

I could have used the counter based maintenance if the reading of operating hours, but here the time based maintenance is taken in account.

Also any thought on the second quarry, means how to cater the maintenance of a pipeline, with two different fluids into it at different times??

Thanks in advance for your help..

Looks an inevitable case of Counter based plan for both. Rest you need to derive. Let some more opinions flow in, so that further clarity and accepted solution might emerge.
