PLEASE Please help me!! Very Desparate.

[viper1511]

This is my first time having a shop, so this is my first time buying anything and I have 1.5 months trying to get this to work, and a lot of $$$.

I bought a used LARGE compressor - IR T30 compressor, nice 25HP phase 3.

My electrician said building is not wired for 3 phase, he cant switch wiring to single phase, suggested run phase 3 to the building or buy a single phase motor.

Ok fine, I bought biggest I could find 10HP single phase motor, now he tells me that the motor will burn out as its too small for the unit. Apperantly there is a size difference also in the wheel and the motor, so it does not match well.

I have a lot of money spent on this, and I am not electrician, I only have 100amps coming in, so a little limited on options. Single phase motor is a good option, but now he says its too small? Its the biggest single phase I could find.

Please please someone help me trouble shoot or find an option for this.

Apparently the motor has smaller rod that is not as tight for the compressor wheel. someone suggested to weld it together, he said no, as the weld will come apart and can seriously injure someone.

I think while my 20-30 hours of doing research in the past remember someone adding rubber adjusted to the wheel rod so that its tight in the wheel, but don't remember.

But regardless, he says that the motor will burn out and this if will work, will not work for long.

simply put, a 10 hp motor cannot be expected to do the work of a 25 hp

 

[aircommuter]

You need to get a smaller wheel/pulley for the motor so it will turn the compressor slower but less load on the motor. Check the website for a compressor that uses the same pump with a 10hp motor if they show one, then get the motor pulley for that one. Otherwise you will have to sell that one and get one that can run on the power you have.

 

[budmur]

Set the compressor outside and change to a gasoline engine would be the best bet in your situation.

 

[Aceman]

Why don't you sell the 25HP motor and pump combo and replace it with a smaller single phase combo? Or just sell the entire compressor and buy something smaller and more practical for home use?

 

[zmaxmotorsports]

Go to tractor suply and check to see what motor they have on a single phase T30 compressor,Id check mine but its around 650 miles from my current location!

 

[rsanter]

You are not giving enough information.
What kind of shop? Home shop, small buisness? Industrial?
What are you doing in the shop? Personal stuff, commercial fabrications?
How big and how many people will be working there?
What is your air needs?
Etc....

The right answer could range from bring in the three phase as you will need it to sell the compressor and buy a little one for what you are doing.

[zmaxmotorsports]

Can you post a picture of the spec plate on the old motor?

 

[Farmall450]

You might be best off getting a run of the mill 80 gallon single phase unit.

 

[viper1511]

Down the line I will have a bigger space with phase3, right now just trying to make it work without buying much else. I did buy 60hp phoenix phase converter in case I move to a bigger space and I don't have phase3.

I really want to utilize this compressor, looks like right now smaller pulley is a great idea, I will try to find one, if I cant, what's the best way of making the motor adjust the size so that it fits perfect into a pulley? Welding is a no no? is there something I can use.

 

[viper1511]

I am trying to open a body shop, right now it will only be 2 people, its a small shop. 3500sq.ft. I don't need a lot of air right now. When I get more people and move into 7500-10000 shop I just didn't want to buy everything again. I bought as quality of equipment as I could - used obviously - but quality so that I can grow into it.

Power limitations definitely I didn't expect, as this is a first time I am doing this kinda *****, but I guess I will get a little more knowledge out of this.

I did buy 2 dust cats, they are also phase 3, but they have smaller 1.5hp that I can use phase converter to run them.

The main thing that I need the air, is the paint booth, I have sata, iwata guns and they require a lot of air I believe one of the guns I bought requires something like 39cfm, and that's crazy, that's why I bought this compressor as I know it gets like 100cfm.

 

[F350]

Just run phase 3 and be done with it. If you expand, it will be a nice ROI on your current shop.

 

[viper1511]

problem is that as soon as I have everything running smoothly, I am out of there, 3500sq.ft. is way too small for me, I cant even put a lift and frame mashine there. So don't want to spend extra money if I cant take it with me. Once I move I am going to take all of the power runs etc...not leaving anything behind.

 

[viper1511]

25HP motor plate

 

[viper1511]

the 10hp motor I got was Baldor, major company so I think I should not have any issues getting smaller pulley for it, so far I think for me its the best option? Any other ideas?

 

[viper1511]

The other option is that 60hp phoenix converter I can use to run 25hp and 2 dust cats, but will need to drop another 100amps and buy 60hp motor, which I really hate to do, if I don't need to.

 

[GarageSpider]

Call American Rotary and buy a phase converter

Don't fool around with an undersized motor and swapping a pulley,too many risks of it not working. And don't weld on to a motor. Good way to knock it out of balance fast, Jackassery.

Motors don't have rods, they have shafts.

Not sure what a 60hp phase convertor needs for a power but it will take most of it to run a 25 hp compressor.

 

[sberry]

Its hard to help some people.

 

[sberry]

Buy another comp.

 

[pepi]

Agree with all the 3phase powered equipment, the conversions will cost will out weigh the cost of getting the service in the shop..

Poor planning ....

 

[Norcal]

The PoCo is going to have a fit running a 25 HP motor on a single phase service.

 

[Fishplate]

What will you do for lights while the 25HP compressor is running on a 100A service?

 

[simpler=better]

I hear where you're coming from, working with what you've got.

x2 Hit up tractor supply or a HVAC place and get a smaller pulley for the motor.

If the motor's shaft is still too small, then call up a local machine shop-they can hook you up with a broached bushing to sleeve the output shaft on the little 10HP motor. Will be an easy job for them, or anyone with a lathe.

Run the whole shebang with the smaller pulley (I'd guess half diameter of the rogiinal or smaller) and it should get you by.

 

[brewchief]

Go buy two 5 hp two stage compressors, use them now and when you move to bigger space with enough power to run a 25 hp compressor either sell them or set them up for backup. If you are able to swap a 10 hp motor on the 25 hp head by the time you reduce the speed of the compressor head with pulleys enough for it to operate you will have significantly reduced it's output.

Even though you increase the speed of a 10hp motor- will it have enough *** ( technical term) to spin a 25 HP pump? Who told you to buy a pump that was undersized by 150% ? A paint gun uses 39cfm ? Does it have a jack hammer function ??

I would check the specs on your gun , and figure out if one or two 5HP or 7.5 HP can run your shop. When the grand plan comes together , take one home, sell them or keep for a back up to the 25 HP

 

[viper1511]

I appreciate for everyone who responded, and those who helped instead of calling me dumb *** is double thanks! I know I am dumb ***, first time doing this, never even expected for it to be a hassle, now I will know. Next time at least I will have some experience and knowledge.

I think yes I will go out and buy 5hp, possibly 7.5hp compressor, backup is always nice as these big units don't last forever and need to be serviced. I will also go out and try to find a smaller pulley. Really didn't want to spend extra $1500 on a new compressor, but I think in any case it will be a nice backup, so does not seam like it will be wasted, and plus the 10hp motor that I got costed $1,000. Once I return the 10hp motor I would only need to add another $500 to be able to get a spare compressor.

I also looked and I was wrong, spray guns don't need 39cfm, the biggest they need is 13cfm at 39psi, so a 5-7.5hp compressor should work. Again, dumb ***, and inexperience to even read requirements, but will know better for next time.

 

[viper1511]

Yes, Todd, I after doing some research I came to that conclusion. Again, poor planning, inexperience, all add to my disaster, but thank you everyone for great help!

 

[Todd.Brock]

Not dumb ***- just learning! Hopefully you got a good deal on the 25 HP because that thing is for and industrial setting. If you can return the 10 HP you would be money ahead. Look at IR at Tractorn Supply or a Quincy from Northern. Air compressor pros may have a deal with free shipping and no tax.

Good luck!

 

[viper1511]

yes, the 25HP T30 in good condition cooled was $2000, I got great deals on great equipment. 7.5HP new was around $2000, so that's why I went used industrial equipment, but at least now I know what phase 3 is and why its cheaper. Again, thanks a lot guys.

 

[nadogail]

I have no idea where you are located, but if you are in a metropolitan area contract someone in the power transmission business; they will have access to a full line of hubs, shaft adapters, belts, motor mounts and everything else to power your air pump.

 

[OccupantRJ]

Forget putting the 10 hp motor on the unit. I run a 25 hp unit at 100 cfm, and a 20 hp unit at 100 cfm. Both are 3 phase. You can hear the difference in the starting and climb to speed on each unit compared to the other. As someone else said, buy a used compressor for now and save the big boy as is for when you move. Smarter and less painful over all.

 

[sberry]

Because something can be done doesn't make it a good idea and money in to a retro fit is whizzed away, all this grief and hassle to destroy something that wont work anyway. Buy something plug and play, 7.5 will run a couple men refinishing cars and would sell easily if needed.
Even a cheap pos type unit will last a long time and if you do manage to wear it out it has done what it was sposed to.
