How Do Rotary Unions Work?
HTML-код
- Опубликовано: 11 сен 2024
- A rotary union functions by connecting a stationary input (supply) to a rotating part, allowing a moving connection to be preserved and permitting the flow of media (liquids, solids and gases).

You can really tell somebody had a lotta fun making this vid, adding extra stuff just for fun. Good work!
Finally I got the idea how fluids are transferred to track motors. And the thing is called Rotary Union. Great video.
I can barely understand this ''magic". But this is fascinating.
The amount of effort that needs to be put into creating something like this is truly amazing.
Amazing video. Like the applications part, because it concluded it perfectly. Thank you for making this great educational video!
This video is perfect in every way!
Very nice job ! Great to learn a little bit more ... Always learning !
Thanks Carlos!
Impressive Video! I am not easily impressed but this is outstanding! Great job!
really cool solution
Great video animation, love engineering!
It was very clear how it is able to turn continuously... but it was not apparent at all why it turns in the first place. I assume these also include a kind of drive mechanism to make things like excavators swivel in place?
Rotary unions themselves do not have any sort of drive mechanism. Excavators have swing drive bearings and hydraulic motors that rotate the cab. This allows the mounted rotary union to rotate as the cab rotates. Hope this helps and thanks for checking out our video.
I see. I didn't get the notification but thanks for following up!
@@DstiRotaryUnions Thank you!!! Is there a video of how the swing drive bearings and hydraulic motors actually create the rotation?
@@gregwoolsey2215 They don't need to in that application, as they don't rotate (relative to the cabin) but would usually act upon an outer ring around the bearing via a gear drive. This could however be directly controlled (hydraulically) in the body from the cab with a rotary union.
@@hierotochan Like a starter on the fly wheel?
Can we use this rotating hydraulic cylinder to rotate solar panel?
So if I understand correctly, there's a... chamber? of sorts that goes full circle so that no matter how much it rotates, the fluid/gas will always be able to reach the exit?
You are correct! Rotary unions are also bidirectional meaning the media can travel into the shaft and out the housing or vice versa. For it to all work correctly the proper sealing technology must be used. Media type, temp, pressure, duty cycle, etc. all play a big role.
@@DstiRotaryUnions Thanks for confirming it. I was curious how it works since I use a machine with this kind of thing at my job (it has four entrances and exits instead of two, but the intakes are all at different heights)
@@urbanberndtsson You're welcome. If you check out our website we have standard rotary unions with 1 - 24 passages. www.dsti.com/rotary-unions/standard/
Fantastic animation agree with all comments below
Much usefull application for the industrial.
I am also developing this rotary union for one of the automobile part testing, facing some problem integrating the system.
Do you have video for mc series duff norton disassemble
I had made one of this but for air. I used it for a gas entrainment impeller
Realy, fine....
does an excavator need a 4 way system for it's tracks? to move the left and right side independent for steering?
In most cases yes, each drive motor requires two hoses; one for the supply and one for the return. However, it can vary by manufacturer and equipment size. Thanks for checking out our video!
Do you have a video for disassembly for duff Norton mcseries rotary union?
Dang. Love it. Nice work.
Song?
Do you know the song name?
Ok
studying for the fl ac exam brought me here looking to see what a rotary pressure joint is lol ummm okay
>How do rotary unions work?
>This is a rotary union... And another... And another...
Well no shit sherlock. Downvote
