Installing a smaller pulley on my compressor – page 3 wireless electricity how it works


The Grain type motor as I call it and what the sales person told me it was used for is all I know. It is double to triple the size of what are used on most compressors and double + what is on my back up T30. You don’t want to even price one that size and you don’t want to pay the shipping on it unless gas and electric phone number it is free. Other than that it is a 5hp and 1725 rpm one. I bought it for like $350 new in town and was very happy with that price because they can cost XXXX. The one that was on my compressor was the same as it and due to a voltage problem I had on one leg over the years it went out.

I do know that you guys are trying to help me out and my dag brain was thinking the other way and as soon as I can get it stuffed in my head correct then I will have it. All I can say is what I think I remember my compressor doing when I installed the pulley the company said would work many years ago and gas outage I still have that pulley and gas pain in shoulder I see it every day. You guys are correct.

James and I bought two new motors to run the fans in our barn. The specifications of the motors were identical except we bought smaller pulleys for the new motors than what was on the old motors. The question was asked Do the fans run faster or slower?As in the above example, the motors have a speed of 90 RPM. The motor has a relatively smaller pulley compared to that of the fan. In the example above, the difference is 200mm compared to the larger 600mm.

I also have another compressor and it is an T-30 242-305TM It has the normal size 5 hp motor grade 6 electricity experiments they come with and a 7.50 pulley and the compressor has a 13 one. Unless one of you have a source on it as old as it is my best guess as to what it puts out is 14 CFM and that is going by a newer one. Maybe calling them might get me a true answer as to what it can do and also check and see if the correct pulley is on the motor. Some I have read about are running 8 ones. I have never had this one in use electricity 4th grade powerpoint but did connect 220 to it and test it out for any noise and it sounded great but was also not under any load so it has not been really tested until it is.

I also have another compressor that is powered by a 11 HP gas motor and it is outside (covered up of course) and was to be used for my son the make some extra money blasting stuff for people that maybe I would coat or he paint or they paint. He had tried to use it with the 8 HP motor and it just couldn’t keep up so I used the 11 HP one that I have been given and had it repaired and had just gas variables pogil extension questions got it back and 9 days after my son’s 42 birthday he passed away last March of a masses heart attack. I did finish the project and fire it up and opened the valve on the second tank and by golly he maintained 90 lbs and run like a clock.

Your motor power limits the product of flow times pressure. Your compressor design limits pressure differential and power input. So the motor sold with a compressor, and the compressor itself are generally optimized to be matched. The pulley sizes are generally optimized to maximize the motor power output so that the setup delivers pressure and flow that meet gsa 2016 nameplate ratings.

Making the compressor run faster might work for short periods with a lower-than-nameplate pressure output. If you try to run the compressor faster with rated flow and pressure, it will not deliver it but will stall. Or run slower. If you put a bigger motor on the same compressor to get higher flow at rated pressure, it might work gas prices going up but the compressor will operate at a higher-than-design temperature and will likely fail faster.

If you put a bigger motor on the thing, and added a really big intercooler and added more ventilation to cool the cylinders, same as above, but you might preserve compressor life a bit. But you’d still be overstressing all the parts in the thing. And you would have spent about the same amount of money as the cost of a new, higher capacity compressor where the motor and compressor match each other.
