I've calculated a whole bunch of grease quantities and ideal intervals for our electric motors in a plant environment. To manage the work load we've fixed our routes to 60 days.
This is where my question comes in -
I'm not concerned about adjusting the grease quantity down when the calculation tells me to less often. Example - calculation tells me to add 100 grams of grease every 120 days and set our program at 50 grams every 60 days.
Where I get concerned is when I have to adjust the 60 day quantity up. Example - calculation tells me to add 50 grams every 30 days so we set the program at 100 grams every 60 days.
I realize that Ultrasonic is the way to do this properly but I'd like to hear some feedback on this case where we have to double our grease addition because the interval is twice what the calculations tell us.
