Scrapping A Champion G250 Rotary Screw Compressor

[DonaldDuck400]

Why you don´t take the motor?

[Armaangandevia1]

1000w= 1 hp

[Aussie50]

@Armaangandevia1 1000W would be about 1-1/4Hp . 750W is 1Hp.

[Armaangandevia1]

@Aussie50 k

[ubuntupokemoninc]

dude if you took the inside out tube bin is like bigger than my house :D

[pumpmaster760]

Aussie 185Kw = 247.989 Hp. thats a big motor!

[10cmsub]

It's very small i can lift it with my finger

[vw77]

So do you do work on the yard in exchange for parts and copper?

[Aussie50]

@vw77 yeh, its a cooperatiev thing. I handle 'difficult' scrap like HVAC gear and compressors. my cash payment is in the copper I get out of them.

[rotarycomptech]

Ed, I responded to yesterday re : the champion air comp you scraped.I did not happen see you had close to 500 vids. You are quite the tinkerer, if you lived in the USA I would hire you tomorow afternoon. I want to clear up some confusion about the starting gear on the comp. It is called Y delta start AKA part wind start.It uses one of thoes timers in the enclosure to go from start to run. All Y delta start applications require loadless starting the air comps inlet must be closed @ start up

[Aussie50]

@rotarycomptech Thanks for the info!, I wish I did live in the US too :D

If I had known it was in working order I may have tried to save it and repair the control panel, but it was also too big for me to accommodate and power.

its jsut one of those things you need to say goodbye to :(

[rotarycomptech]

ok to set the story corectly I work on rotary screw air compressors every day for the last 25 years.from 25 to 250 hp the compressor that was scraped what a shame the pump AKA airend was rotateable meaning repairable a used 250 hp air comp like this one repaired for around 8 to 10k could sell for $25 to 30k so you think you made out scraping this unit ? not so much the water in the electrical enclosure not a big deal so every one knows rotary screw comps range from 3-600hp

[Aussie50]

@rotarycomptech actually there was nothing wrong with the unit apart from general wear and tear.

the customer who got rid of it paid $200 for it and never installed it because it required too much power to run (he was doing sandblasting) since nobody else wanted it he sold it as scrap.

we got many times what we paid for it so I don't care that it wasn't repaired.

[karlomontemayor]

that thing is huge! did you get a good profit from it?

[Aussie50]

@karlomontemayor hell yeha, much of it was the scrap yards profit but I still got a trailer load of parts to play with and mains cables to strip down.

it was well worth it!,

[KrankieV2]

1 HP is about 746 Watts. so 185kW is almost 250 horsepower!

[VREDFOX]

impressive machine!!

[Tomthetoolman100]

if you wanted to test the board use a scouring pad to get rid of corrosion from the parts might work on some of the tough stuff

[iib8903]

bet you got loads for the scrap

[LHUPA]

What kind of monster it is? We can use a such compressor for air conditioning like large commercial instalations as depatment stores and shopping centers or simply an industrial version of an air compressor for large factories ect.? I remark that it's electric... Surely 550V and above! This machine can kick the ass!!!!!

[Aussie50]

it really is a monster!, its 415V 3 phase, 250Hp motor

It not a refrigerant compressor either, just air for large manufacturing facilities like Nylex plastics, or similar big factory.

[LHUPA]

Nylex have a such compressor? Surely for making all air operated tools and robots (If it there) - A screw type compressor must use a fluid as hydrolic oil to operate properly! I have made an experiment with a 50's FRIGIDAIRE rotary compressor (The sole company in the era to use a rotary compressor in their apparatuses) and I have rebuilded the compressor with no oil completely dry (solely a pinch of oil to lubricate the motor parts) and SURPRISE... absolutely no air from the compressor!!!

[rotarycomptech]

@LHUPA in a rotary screw air compressor the fluid is used for cooling sealing or compression and lubrication it is no suprize to me the refer comp is a rotary vane it has no oil cooling it is cooled by cool refigerant entering throug the suction line thay do make rotary vane air compressors and the oil is used for the same reasons as a rotary screw air compressor hope this helps you out

[leokimvideo]

well done on the 300th video, thats some scrap footage..!

Mate I have added you to my partner friend list, lets see if I can't get you over the beer money line.

Anyone subscribing to me will have the second option to sub you, it's networking 101 on the tube.

[Aussie50]

Thx leo!, i really appreciate it!

[ihatespam1977]

Interesting find. Too bad the actual compressor wasn't yours to keep. An autopsy of a blown screw compressor would have made a great video.

[HDXFH]

whack your jag engine on that compressor that would make a kick ass workshop air compressor

[coolbluelights]

whoa that thing is massive! what was that used for? inside some factory or something to control pneumatic systems? lol @ 6:05 that guy could use some forklift lessons xD I've done some things with a lift you wouldn't believe :D if I ever get into a line of work that doesn't require use of a forklift I'm gonna have to buy one for myself!

[Aussie50]

The Compressor is from a very large factory, probably plastics, automotive or textiles.

The fork driver is a bit of a hammerhead, but he gets the job done fast :D, and owns the yard, and gives me free gadgets to play with so I aint complaining ;)

[ControlledExplosions]

neither would I ^^

[animebsd]

what would happen if u wer to give that motor a spinning start with 110 volts? or whatever power u got overe there?

i pluged a 3 phase 10 hp into the wall and gave it a spin and it started but had no power wat u think that would do?

[Aussie50]

A motor this big would blow the breaker panel no probs. its like a dead short across the wires.

i would need ot give it at least 300 amps in 240v single phase, or 100 amps 415V 3 phase to get it running

[animebsd]

eould u even beable to do that?

[DragonFlyback256]

@Aussie50

Prob still would have been good for a generator project beside the Westinghouse one. Too bad this beast is gone now. I doubt i can tell any new with that, almost ANY kind of motor can be used as a generator. =D

[Aussie50]

@DragonFlyback256 yeah that motor would have made a awesome generator!, I could have bought it for $500 or so, but I have no place for it :(

[pixuma]

we have a rotary screw compressor at school, i't quiet, runs smoothly and it provides huge amounts of airflow

[pow0006]

Thats got to be the biggest air compressor motor i have ever seen! ,im a little jelous,good luck with it Ed.

[008626]

pretty sweet deal right there

[67tr876]

wow thats a nice find i would have got that big motor. and i love the fans i hope you can do a vid of them runing :) and was that a root's blower ?

[Aussie50]

lol that big motor weighed just under 1ton, I'd have no way of moving or using in :(

I'll try and get a fan vid up soon

[Aussie50]

Champion call the compressor a screw type, and it dose look like a Roots design.

[animebsd]

keep all the motors are u?>

[Aussie50]

Just the 2 fan motors.

The big one is being scrapped, roughly $500 worth alone.

[FedeBo91]

is really great!!!

[douro20]

Now don't destroy the motor; that's a pretty valuable motor.

[Aussie50]

The motors not mine to decide on, the scrap department has already loaded it on the truck and will take it in tomorrow to the big yard.

[douro20]

185 kilowatts is 248 horsepower.

[Aussie50]

thx man, shit thats a lot!

[animebsd]

do u think if u pluged the giant motor in 115 volt power it would even spin?

cuz i got a 10 hp motor that was 330 v and i pluged it in and it buzzed then i spun the shaft and it started it had no power tho but did work

[30GB]

that sucks that water was in it

[diymania]

Ed, i doubt its a rotary screw, it looks more like a roots blower.

[Aussie50]

Champion call it a Rotary Screw, but you are right, they are similar

[rotarycomptech]

@diymania this is a rotary screw air compressor for shure a roots type blower does not use oil for sealing like the rotary screw comp also PD blowers AKA positive displacement max PSIG 15-27 used for low pressure high flow

[mattyvt93]

Ohh nice find Ed! :)

[V8Jagnut]

very nice unit. was the fork driver drunk?

[Aussie50]

lol nah, just in a hurry. I wanted to put a chain or bar through the eye bolt but he insisted on trying to lift off the housing and spindle

[TheCoolmaster100]

Wow those fans are cool. Are they single thase or three thase. Ed would you be able to do a video of those fans running?.

[Aussie50]

They are 3 phase 415V and I havn't had time to make my phase converter :(

I can single phase run them though. I just de-greased one a few mins ago

[TheCoolmaster100]

Okay. Ed I guess they would both blow a gale when they are running. I noticed because the fans are 20 years old they would both be solid machines. I also noticed that after they get turned of after spinning full speed they would coast for a long time.

[Aussie50]

yeah I was spinning them by hand, good quality ABB motors, 1Hp each

my rear workshop fan is a larger version of them, very powerful at full motor speed

[Aussie50]

I wouldn't reccomend using one top blow air in a house either, way too powerful!

[TheCoolmaster100]

Ed Imagine using them to extract the air out of the house in a window. The would be like whole house fans.

[Aussie50]

Yeah, for air extraction they would be fine

I have twin condensing fans for that later on in summer when its scorching hot

[TheCoolmaster100]

Ed I guess they would be loud when running because of their design.

[Aussie50]

yeah, I'm not concerned about noise
