How to control the speed of a pneumatic cylinder

[@pavelpetrochenko6417]

Why is it that old KZbin videos are always the good ones. Thank you for this video, I now know what I need to do 🎉🎉

[@ultimatehandyman]

Glad it was helpful!

[@ultimatehandyman]

@airofan No, I don't thin it increases the force. The force from the compressor will never be increased past it's maximum. But by slowing down the cylinder by using a restrictor on the exhaust it ensures that the cylinder operates with full force.

[@mprior108]

Exactly the information I was searching for. The mufflers were well explained.

[@ultimatehandyman]

I'm glad the video helped Thanks for the comment 👍

[@faganwagner7411]

Thanks so much for the interesting video. Can you please explain how to use a fast up and down movement, without a bang on the up and down movement.

[@amitpunjani1426]

Thank you so much for this and all your precise videos on all tech information. Very very helpful.. great work, i request you to keep up this good work 👌

[@ultimatehandyman]

You are welcome Thanks for the comment 👍

[@RollinShultz]

Is there a rocker foot pedal that gives control both ways according to how far it is pushed?

[@ultimatehandyman]

I think this is what you mean- www.amazon.com/Position-Center-Closed-Pneumatic-Operated/dp/B00E5NNPOQ

[@RollinShultz]

@@ultimatehandyman that looks like the ticket.

[@johnjackson4105]

Very well explained, thanks for the video

[@ultimatehandyman]

+John Jackson You are welcome Thanks for the comment

[@fatrobotnew]

Thanks for video. Please explain one things- how the stoppage of pneumatic cylinder is implemented? Air pushs plunger till the end of cylinder and then what? Is there some kind of limit switches or something?

[@ultimatehandyman]

+fatrobotnew You are welcome. Yes, there are two inbuilt pneumatic plungers that stop the carriage at each end, when it reaches it's limit on the rod less cylinder. But the normal pneumatic cylinder just extends or retracts as far as it can do with no switches etc. it simply moves until it reaches the end of it's stroke. Thanks for the comment

[@fatrobotnew]

+Ultimate Handyman Thanks I get it.

[@ocean374]

Will the speed control valve work on a single spring return cylinder I want it to go down slow but when I release the handle it returns fast on its own because the cylinder is spring load hope I make sense thanks great video

[@ultimatehandyman]

I'm not 100 certain, as I have never tried it before, but you should be able to slow the speed at which the spring retracts, by restricting the exhaust air from the cylinder ( I think ). Thanks for the comment

[@vinoddesai4688]

Thanks you sir, solved my problem......desired video

[@ultimatehandyman]

Thanks for the comment

[@-destroyingyouverbally7614]

Is there any way these can be program via remote control?? And one more question from your experience from these going back and forth. What normally is the life expectancy that u got to replace the parts

[@ultimatehandyman]

You should be able to rig the solenoid valve up to a remote wireless relay- kzbin.info/www/bejne/qmfao6SgibOWiq8 These types of actuators are normally very reliable. They are used in industry, where they are used in manufacturing plants that run 24 hours a day, 7 days a week and normally last for years before they need servicing (providing the compressed air is clean, dry and lubricated) Thanks for the comment 👍

[@frankjames1955]

lets say you wanted the cylinder piston to go back and forth by itself without you using the hand switch , how would you do that?

[@ultimatehandyman]

It's not something I have ever done, but this might help- fave.co/3bXC0Ye Thanks for the comment 👍

[@frankjames1955]

@@ultimatehandyman thanks

[@GeorgeGardinier]

that was good, do you have a part number or where it was gotten

[@ultimatehandyman]

+George Gardinier Thanks, the adjustable mufflers and solenoid valve were purchased on ebay. The pneumatic cylinder and rod less cylinder were bought at auction a couple of years back, although you can also get them on ebay etc.

[@usamahibrahim2201]

I still don't get about the pressure, force is mass times acceleration, if we make the cylinder slower will the mass increase? I'm sorry about broken English

[@ultimatehandyman]

Not sure about that, I’m a maintenance engineer and not a scholar. We were only taught to slow down the speed of a pneumatic cylinder using the exhaust, so that the cylinder still has full pressure to move it 👍

[@Maxsdiscos]

How do you drive these, do you need a compressor?

[@ultimatehandyman]

+Maxsdiscos Yes, you need a compressor to generate the compressed air to run these.

[@jasonh1684]

So what are the 2 black devices on the the sliding thing, shock absorbers?

[@ultimatehandyman]

They are inbuilt pneumatic plungers that stop the carriage at each end, once they are depressed it prevents the air from continuing to push the cylinder. Thanks for the comment

[@deschvid]

They look like they could be couple Impacta shock absorbers. They will often be used in conjunction with a switch. An alternative to that Control Flow valve you're using on the air cylinder, is a Kinechek. They provide a constant feed rate along its entire stroke, quite smoothly. Nice video!

[@k9yeti264]

What parts are used in this setup? I would like to know if it can be incorporated in an exoskeleton design to lift heavy loads on the legs.

[@ultimatehandyman]

+K9Yeti The rod less cylinder is not that strong to be honest, unless you get one with a large bore cylinder but they are very expensive. I'm not sure which model I used without checking it, but the force on this one is not at all strong. There is some technical information here that might help-www.cmafh.com/images/Master%20PDFs/BRP%20CYL/Rexroth%20Rodless%20Cylinders.pdf

[@k9yeti264]

+Ultimate Handyman Oh ok. Thanks very much!

[@ultimatehandyman]

+K9Yeti You are welcome. Sorry it took me so long to reply, I read your comment a few days ago and only remembered today that I had not answered- It's my age LOL

[@jeremyrose3034]

How many inches is the throw on that cylinder?

[@ultimatehandyman]

Not much, it's only about 2" 👍

[@mrdavidurquhart]

Hi thanks for another great clip. Can I ask, where do you go for pneumatic components?

[@ultimatehandyman]

+David Urquhart I normally get them from ebay, such as this shop- fave.co/1pFrpYQ Or sometimes if I'm not in a rush for them I get them from Hong Kong/China via ebay. The rod less cylinder was bought at auction though. Thanks for the comment

[@omarofuae]

Hello Sir. Thanks for the excellent video. I have a general question about hydraulics. So when you move the lever in one direction, it opens the chamber between the compressor hose and one of the cylinder hose while opening the other cylinder hose to the atmosphere to release air. Is my understanding of this correct or incorrect? Thank you.

[@ultimatehandyman]

+omarofuae You are welcome. Hydraulics are slightly different as there is no venting to atmosphere, so the oil returns to the tank. This explains it well- kzbin.info/www/bejne/gZjTmYJjqpyAorM Thanks for the comment ;-)

[@airofan]

Thank you for this info. Does slowing down a pneumatic cylinder increase the amount of torque at all ? Cheers! John

[@ElectronPower]

Torque? You meant force that the carriage exerts? -No, the force only increases if the pressure is increased and is not dependent on speed.

[@federicos9821]

hi, i want to open a door that weights aprox 600 pounds and measures 9 x 9 feet. Can you give me an idea of what i need? The idea of using pneumatics for my project its because i know pneaumatics are way faster than electric linear actuators. I want my door to be opened in less than 5 seconds and closed in 5 seconds too is it possible? thanks

[@ultimatehandyman]

For something so heavy I think you would need hydraulics to get the speed you require, but then it will be expensive and you will need a lot of safety devices to prevent anyone from being crushed.

[@mbreto1]

Question, where did you find that actuating valve?

[@ultimatehandyman]

+Michael Breto I bought it from ebay- fave.co/1OFS3M3Thanks for the comment ;-)

[@mbreto1]

+Ultimate Handyman do you know what the lifting capacity of that rodless cylinder would be in a vertical application?

[@ultimatehandyman]

+Michael Breto You would have to check the manufacturers data sheet, or if you are buying it from a shop the people selling it should know.

[@ultimatehandyman]

+Michael Breto Sorry, misread the question. No, I don't know without looking it up. We use these at work to lift flexible pipes from one floor to another, they are pretty strong but I'm not sure of any figures etc.

[@TomHowbridge]

I have no use for this but I case I do thanks for sharing !

[@ultimatehandyman]

+Tom Howbridge Thanks Tom, I'm making a Halloween prop using this, so it will help people that also want to make one. Thanks for the comment ;-)

[@TomHowbridge]

Aha I see well have good fun !

[@raptraerialimagery4741]

Where do you get the joystick to activate the piston? What's it called. I want one :) Thank you in advance....great tutorial

[@ultimatehandyman]

It's a 5 port, two way lever valve- fave.co/2h16Y6F When buying one you have to get one with the correct sized ports and threads for the fittings that you are using. I normally get them with 1/4 BSP ports which are common in the UK, the one I linked to on ebay has 1/4 PT ports, which are used in the USA. Thanks for the comment

[@raptraerialimagery4741]

Fantastic! Thanks

[@LouisDobbelaere-k3l]

Nice Thanks! we can resume production !

[@ultimatehandyman]

I'm glad the video helped Thanks for the comment 👍

rodless 1000mm how much

[@ultimatehandyman]

I have no idea, sorry. I bought mine at auction

[@topbanana188]

What do you use this sort of stuff for?

[@ultimatehandyman]

+topbanana188 This kind of equipment is widely used in industry for controlling or moving things. I'm making a few things in the future using these so this tutorial might prove useful. I'm working on a Halloween prop at the moment using the rod less cylinder and a solenoid which is activated by a 12v PIR sensor.

[@alburaqindustrialsupplies]

how control the speed of four pneumatic cylinders they run equal speed up and down ????????????

[@ultimatehandyman]

You would probably have to use a manifold and then use a restrictor on each of the outlets and adjust each one accordingly.

[@alburaqindustrialsupplies]

Ultimate Handyman I use it but when cylinder up four cylinder different speed not up and down same speed can you send me some idea or pic how can control cylinder stock

[@alburaqindustrialsupplies]

40 mm bor cylinder stock 600mm and use 6mm pipe and fitting but not up and down equal speed

[@alburaqindustrialsupplies]

I'm use four way hand valve pressure 6bar

This might be more complicated than I first thought, this might help- www.hydraulicspneumatics.com/other-technologies/book-2-chapter-22-synchronizing-cylinder-movement
