They had scroll technology around 60 years ago. They had a seal between the scroll and it routinely failed. The machining process gets the tolerance much lower now so the gasket is no longer needed. I’ve seen the cut outs of these scrolls but never seen a running cut out. This was very cool thanks for the video.
@@jamesv4463 the scrolls are covered in oil. The oil acts as a seal that covers the microgaps and prevents the air from leaking. It also covers the surface of the scrolls and prevents them from getting cold welded together.
@@aryanarya8741 from my understating the metal was actually making the seal, hints why this kind of compressor can actually improve over time. it wears into eachother
@@jamesv4463 it is impossible for a machine like this to run without oil in my opinion. the cold welds will increase the friction so much and will destroy the seal. no matter how perfect the seal is there is oil involved that protects the surface
That is a fantastic video! You are right there are three bearing, drive bearing, middle is the straddie bearing and the lower bearing.The lower bearing live in the oil so it does see as much wear.The straddie bearing take a ton of abuse especially on liquid flood back.I don't see that much wear on the upper bearing when I take them apart. Five Star video!
Wow. Great feedback @dizziedallas . I worked on a unit today that had a scroll that was vibrating terribly. My guess is the compressor had liquid flood back recently since there were no pressure switches installed and the system leaked out all the refrigerant. I found the compressor off on internal thermal overload
Thank you So MUCH for this video. For years I have wonder how a piston compressor could fit my window AC unit!!! Now I understand.. It never was one!!!
one of the failure modes for these compressors is the bottom bearing which is held in by 2 to 4 cap screws. the screws can loosen up and the bottom bearing will knock around,
I used to work at the factory that made that little plastic tube that you see attached to the side of the fixed scroll. Perhaps an older unit. The ones we made were of black plastic instead of white.
Hey Ulises I'm a little late on the vid lol I have a ZR125KC scroll that I want to tear open and see what's going on on the inside. What VFD do you recommend for that compressor ? We use 220V out here and 380V 3 phase. Just not sure what capacity I should use. It'll just be dry testing the motor like you reviewed here
is the noise at 1:34 "like a moped" is normal ? My heating pump is doing same noise, I've had a pac for a few years, and I find it surprising that it makes this noise.
Honestly it would been nice if you could given a tutorial explanation in this operation and what the parts are actually doing for us Dummies 101. Thanks.
@@actechformallyyomama746 the coldest part of the system. That's why you have a crankcase heater is to keep the compressor warm and avoid flooded starts. Sorry and I meant refrigerant migration not oil migration.
Farther down Joe Shearer prompted the original poster's reply: "Joe Shearer lol yeah I did. That vfd goes up to like 500 htz. I was scared to take it up to 100 htz. Almost double the rpms. I have another compressor. I might try to take it to 200 lol."
Karl-Alfred Römer their are ports for oil to run through the entire compressor to lubricate the moving parts. Oil runs through the entire refrigerant circuit.

I love VRV variable Refrigerant volume system that's why I love and like liked this video and I am HVAC technician so i loved the AC video but this one is really ossooom...✌️
That's great that you did this. Even people who "know" what the scroll is can learn about them. Thank you,

I would like to know how they don't cold weld. It's hiding a secret. In the factorys you cant even take a phone Into where they make the scrolls

thank you..
it's hard finding video like this show the inner workings of a compressor

dizziedallas thanks man. I appreciate it.
Yes a fantastic video. BTW my COM07359 5ton has a one way high side valve so there is no liquid blow back.

Best teardown I've seen, thanks for uploading, man!
mike_HVAC thanks man.
@@UlisesPalacios please make a video how to make ? motorbike pump in using air conditioner compressor.
Running cut out is amazing!!.. Thank you so much
Thank you So MUCH for this video. For years I have wonder how a piston compressor could fit my window AC unit!!! Now I understand.. It never was one!!!
Ii have to thank you for your efforts, you knew how to research and figure out how to demonstrate for yourself and others how it works.

Sparky Arcblast that’s cool. I’m guessing that’s for oil. To drain back into the crankcase
Great effort. Nice to see what happens inside a scroll compressor.
How to remove water mixed in oil incase submerged evaporater develop a leak?
Very cool!!! You have no idea how cool an important and the amount I learned from this!! Thanks!!
Thank you for taking the time to shoot and share
Pretty sure you’ve been taking things apart since about the age of three 😂. Extremely impressed with your lab work.
Sounds like a Ford model t
Peace

Awesome! Great piece of technology. I was so curious now I understand.
Parabéns melhor vídeo já feito! Graças a ele consegui entender o funcionamento do sistema!
Это пожалуй лучшее видео об устройстве спирального компрессора.
Great video! What Model VFD controller are you using?
I'd love to know that as well.
I assume that is a three phase motor with variable speed drive.
a little Madd scientist action , that was neat
JH HVAC & Plumbing thanks man
JH HVAC & Plumbing thanks buddy
THATS HOW THIS WORKS!? I NEVER KNEW. WHAAAAAT!?!? THANK YOU!!!!
Can you run compressed air thru the outlet and make a three phase alternator or is there a check valve to prevent this?
There’s a discharge check valve to prevent reverse rotation. Scrolls only run in one direction
13:38 does it need that much power to run how much power does it need to run fully?
is the noise at 1:34 "like a moped" is normal ? My heating pump is doing same noise, I've had a pac for a few years, and I find it surprising that it makes this noise.
What kind of amp draw is the compressor running with no load?
Very cool! Thanks for sharing!
Fox Family Heating and Air Conditioning thanks Greg.
VERY GOOD CONTENT! BECAUSE NO ONE KNOWS ABOUT COMPRESSOR HOW ITS WORKS ? THANKS FOR YOUR VIDEO
the small hole in the top of shaft is the "centering hole" for machining.
throttle bottle yeah. I figured it was for something like that.
Variable DC power supply for this experiment?
Did you try minimum freq and RPM, when the compressor starts to lubricate itself properly please? (Oil pump start pumping oil)
may be it is medium scroll type 1 , i 'm not sure but i think the motor lower bearing is in contact with the lubricants ..
Won't the vacuum side go low before the pressure side as it wears out?
Thanks for the video. Did you find anything broken when you took it apart?
Very good I was waiting to see it.THANKS
If it runs dry do to a leak will it recover original level of vacuum?
Will scroll compressor get damaged if it's made to run in reverse?
Super cool. Thanks for taking the time.
Nice little VFD
Honestly it would been nice if you could given a tutorial explanation in this operation and what the parts are actually doing for us Dummies 101. Thanks.
Compressor oil will mix with refrigerant gas?
SARAWESHWARAN BASHKARAN it will blend with the liquid refrigerant. The purpose of a crank case heater is to keep the oil warm so they don’t blend.
@@actechformallyyomama746 crankcase heater is for refrigerant migration.
Really where is it migrating to?

Good ilustration-SUBSCRIBED
That was cool Ulises. Did you put baseball cards in your bicycle wheels growing up?, ha ha.
polishtheturd mickelson lol 😂 thanks
That was a cool video. Good stuff. Have a good week at work, Don't let them work you too hard, lol.
Did you take this from a portable ac? If yes, which one?
0:21 and 0:29 Was that the oil??
Excellent tear down. 👍👍
Nor-Cal Refrigeration & H.V.A.C thanks man
hey smurf boner's dad!
Can this compressor be fixed once burnt? just asking
Very good video to know about scroll compressor but safety is the first
Did you have VFD controller here? What kind of motor controller setup did you use? Was this seized due to floodback ?

How comes the lubrication oil come from the bottom of that thing to the scroll compressor in the top?
Karl-Alfred Römer their are ports for oil to run through the entire compressor to lubricate the moving parts. Oil runs through the entire refrigerant circuit.
Thank you. Great presentation.
why would there be equalized pressure on a scroll brand new?
Unlike reciprocating compressor. On scrolls the pressures equalize in the compressor when it’s off
@@UlisesPalacios I realize that and thankyou...How bout when it is running.
Great educational video.Thanks for making it.
Very good illustrative video !
looking for a scroll compressor without a built in motor.
This is a great video. Thanks for sharing
Is That From Trane Central Air Conditioners?
That's cool sounds like a lawn mower engine. Did you have it on a vfd
Best autopsy yet you can see how it oils that top bearing and everything!
Joe Shearer lol yeah I did. That vfd goes up to like 500 htz. I was scared to take it up to 100 htz. Almost double the rpms. I have another compressor. I might try to take it to 200 lol.
Ulises Palacios you thinkin about a scroll mod to that Honda ?
Joe Shearer lol 😂 they now have an all electric dirt bike. Alta 15 grand.
Joe Shearer yeah. That's what I wanted to see
what is the TORX screw size??? M7?
which VFD are you using?
Wow that is awesome! So not safe but that was great. Nice video dude
This was so insane and cool
Is this inverter?
Could one of these be used to compress air for tools?
These are used in air conditioners
Excellent presentation....
That is cool. Eccentric oscillation.
very educative. Thank you
is it oilfree ?
Thank you for this video.very very amazing.
cool，The video at the beginning shocked me。
As it ages and the system has leaked down a few times it won't build sufficient vacuum and the evap coil floods
This is cool! Thanks!
fantastic video
Typically, what sizes of external torx do you come across when tearing this compressors apart?
Der Werkzeug König there are many different compressor. Different torque ratings for every bolt. Some are over 150lbs to as low as 4lbs.
Compreesor not working power ok terminal ok whatis the reson
Nice video. Nice vfd also.
Thank you for this video.
If it's working you can turn it into an air compressor if you have a welder and you fixed it 🤔
