Ok - sorry for all the freegin calculations.. but I measured and re-measured the "Outside" of the pulley, since thats what the compressor flywheel measurement of 17.75" is based on.. and since these numbers didnt make sense.. I used the inside diameters.. but that still didnt make sense..
So, here is my exact numbers of the CURRENT motor and Pulley thats on the compressor.. PLEASE tell me if I am screwing the pooch somewhere..
Motor Pulley Outside Diameter: 7.75"
Compressor Flywheel Outside Diamer: 17.75"
Motor Speed: 3515 RPM (3 phase, 5HP)
Soooo... this means the current RPM's on the Compressor should be:
(7.75 / 17.75) * 3515 = 1535 RPM
Can that be right?? this should be waay too high for a Mariner block?
I'm thinking of throwing a Leeson single phase 5HP motor running at 3450 RPM in there..
If I use the exact same pulley the single phase motor will produce this rpm on the compressor side:
(7.75 / 17.75) * 3450 = 1506 RPM
To my understanding this is still waay too high and will probably over draw the motor..
I'm guessing here, but to drop the RPM's down to a reasonable 1100, I would have to drop the pulley down to a 6.0"
(6.0 / 17.75)* 3450 = 1166 RPM
Any comments/Advice/concerns ??
