I have a 60 gallon upright compressor. The original 3.7hp Chinese motor died a horrible death and I replaced it with a 5 hp Baldor motor I happened to have. The original motor was 3450 rpm and the Baldor is 1850. I have the original 12" puiley on the pump and an approximately 4" pulley on the motor. Obviously it runs slow, and takes a long time to get up to pressure. I need to know how large of a pulley to put on the 1850 motor to bring the driven pulley's speed up to approximately what I was getting with the original 3450 motor. The original motor pully was about 3" diameter. I'm very sure that the Baldor will take the heavier load, it used to run on a 100 gallon horizontal 2-cylinder compressor, which was obviously set up for the slower rpm. Any math wizards have a suggestion?
Any ideas would be appreciated.
Thanks.
