How to Control the Speed of a Pneumatic Cylinder

[@thobiex]

This is the first time i've really looked at pneumatic cylinders. I'm in love already! XD

[@buddha2845]

This is what I was looking about,,I had a curiosity about this speed control feature,and today got my answer,, I have subscribed the channel now

[@specialservicesequipment393]

If your using online flow control valves, BE SURE to check the flow direction in the valves, if you have them installed backwards, the cylinder will act eratically. I use inline flow control valves with rapid exhaust, reversing the valves caused static speed operation, slow retraction even when wife open.

[@jamesg8246]

My retraction is usually fast when the wife is open.

[@Vorocity2000]

Technical detail alert: Whether you use port flow controls or mufflers in both cases you are restricting exhaust, not the flow into the cylinder as the video indicates. You can see this happening since tightening the control at the nose of the cylinder is slowing down the extension, meaning slowing the exhaust leaving the front of the cylinder as the rod extends. This is the way you want to do it since it keeps pressure in the cylinder giving the cylinder more control. If you were actually restricting the flow of air into the cylinder, the cylinder loses control in its stroke. It needs the exhaust air to push against to maintain position.

[@jvmiller1995]

You know the exhaust flows out as well. You are controlling the flow of the exhaust and that sets the speed by restricting it but it is still a flow control. Is it not? Don't answer that was rhetorical

[@calebmohr4136]

I’m at 1:54 and stopped the video to find this comment!!!

[@maheshwarannarayanan]

Thank you brother.....

[@slimroit]

very good video to learn the basics , well done

[@Kilz78]

It's much easier, more reliable, and cheaper to place a speed control muffler on both exhaust ports of the valve body. It's better to meter the airflow out of the cylinder than into the cylinder.

[@davidmok108]

there's a saying that goes by, "when in doubt, meter-out!"

[@securityrobot]

Very good and instructive, thanks for posting.

[@naboulsikhalid7763]

[@donwatson2741]

very well explained,thanks.

[@jtwo6307]

awesome explanation. thanks for sharing!

[@collectorsinfo]

Thank for this, great help for a newbie. Is there a way to control length of stroke . I have an item that i would like to throw 7mm forward & 7mm back & can only find 5 & 10 mm stroke units & didn't want to break the part i want to control. Thanks.

[@IMTIYAZNABIMASOODI]

Nice vedio thanks a lot I want to install it on carjack .Where can I find there solenoid and other things plz provide link.I am from Kashmir india

[@vishalmath2480]

Thanks for the video.

[@carrolljohnston2664]

Much better control i.e. Accomplished by using flow control valves that control the air exhausting out of the cylinder. They can be set at different flow rates for extend speed and retract speed. This gives great cylinder rod speed control in cylinders with larger bore , longer stroke cylinders with oversize piston rods. I believe it is better to control air exhausting the cylinder, should an airline fail, the cylinder will still the controlled flow exhausting.

[@thuong3818c]

He is doing that. The valves that he are using restrict air coming out of the cylinder, not into.

[@philipvitkus2109]

Pretty good instructions, thank you!

[@jvmiller1995]

The flow valve on the solenoid valve works best if you have 2 or more cylinders moving together

[@kangooroovd]

thanks a lot for sharing the video

[@J.Quin.]

Could you use the flow-control muffler on only the rear port to get a single action? If the piston is able to simply be pushed back? If not with a flow-control muffler, is there another way to achieve this? - Assuming a single action piston of the required dimensions are not available.

[@davec.3198]

When in doubt, meter out! Say it 5 times and you'll never forget it. :)

[@VivekAnandJ]

Thanks a ton for this awesome video. Would be grateful if somebody can help with a doubt. How do you control speed where force exerted varies. Ex: we have a section on a pivot lifting a flat surface from horizontal to vertical. Like a vertical top door on a kitchen shelf. When horizontal, load is more. When vertical almost zero.

[@sufiyansaiyad2003]

What is the minimum working time of 1 complete stroke after attached quick exhaust valve??

[@JAI_SHIVSHAMBHU.]

Very nice video

[@jouharali5711]

well explained 👍

[@jaiminpatel4454]

what is the best way to change the speed of a cylinder?

[@FR54321]

yea i am working on a big project it is a robot leg and i need lots of force but not to fast and this video is great

[@scottg9236]

I need to know how to get an actuator close at one speed a slow down so the door it is operating doesn't slam. My door is part of a ride and having the door block the track is not a speed issue. But when the vehicle is approaching the door I need it open fast enough so the vehicle won't hit the door. If the door opens fast enough but so fast that it bounces and hits the vehicle as it passes. I need the last few inch or two of the actuator slow down. How would you do that.

[@rolenmsd]

Do you loose push or pull power when slowing down the pneumatic cylinder?

[@monexchannel9827]

Brilliant!

[@StickOnHair]

What weight can they lift? How do you prevent that loud noise?

[@georgealbo]

could you specify the work speed like 20cm/sec 20cm/100ms ? for the shown cylinders

[@jamesfrancis303]

Great explanation..

[@michaelleewagaman301]

How did you connect the quick exhaust ports to the cylinder?

[@ashanmadushanka4265]

How many weight can press using these size cylinder ???

[@AsadAli-id9fv]

thanx for such informative video. is there a way to control the sound of exhausting air to eliminate noise

[@garyklopper6976]

Use a Muffler / Silencer . The flow controls in the vid that were fitted into the exhaust port f the valve are Restricted silencers. There are different types of silencers available to suit the application.

[@06PYTHON]

Okay I have a kit car that I want the doors to open with the Press of a button can I do this with pneumatic cylinder. 1 button to open and stay open ...and a different button to close.

[@rusticagenerica]

Stunning video. But what if you want to build a platform with a seat on it, for virtual reality, and you want to have variable speed all the time ?

[@barrettt8661]

I think you would want to use electric actuators, they are more "controllable"

[@jakubp4755]

Or use proportional valves, where you will be able to electronically set the flow to the cylinders.

[@mohamedhatem3694]

Motors would be what you seek then

[@ethanfishell1930]

How would you adjust the pressure without doing it manually?

[@LovemeAquarius]

Excellent !!!

[@rayfulmer6968]

Please do video for long stroke cyl. ie: 1.24" bore x 30" + or - stroke. Used as a product pusher they tend to jump when they first contact the product.

[@payasofeo69]

your pressure is too low or you don't have enough flow. if your cylinder is the right size for what you're pushing with enough pressure and flow it will not jump.

Where to buy this product . . Double acting cylinder

[@georgealbo]

Dear sir, what is the maximum speed can ican i get using using (quick exhaust and Pneumatic arm ) or (solenoid and pneumatic arm)

[@davidbui1151]

What made the cylinder unable to stop? One of the magnetic switch light at one end of the cylinder stays on and the cylinder is pushing back and forth in a non stop cycle.until I have to unplug the power cord.

[@zombietodd69]

How much weight can these things push/pull?

[@quyetphung9221]

what is type of pneumatic cylinder in video. I need it

[@pascalernest2916]

Does this depend on the pressure or size of the cylinder? If I have a bigger cylinder, wil this solenoids control it? Will picoboo control it? Whats the power rating of picoboo? Can one picoboo control two solenoids or two cylinders?

[@darrylbarrow4952]

Can 2 exhaust speed controls be attached to a manifold to control the speed of all items hooked to the manifold?

[@ajaydev8097]

Can we control speeds in hydraulic and hydropneumatic cylinder

[@jaypeeestrada4369]

What size of pneumatic u use now?

[@danieldelcastillo5535]

I have a ball valve with a rack & pinion actuator single acting fail close. Do I need to look for a solenoid valve that will restrict in-out flow to make sure it will open-close slowly? My boss is asking me to help him with this on a vapor line that a quick response on the equipment is making trouble with the operation of the equipment. I will like to know your recommendation

[@garyklopper6976]

Hi Daniel. You can use the flow controls that you saw in the video. If you are using a single acting actuator, normally only takes one application supply ( one pipe to actuator). you can also use an in-line flow control valve or even the restricted silencer type that fits into the exhaust port on the valve. make sure you are using the exhaust side to control your speed or the actuator when turning will get a shudder.

[@MrCoder101]

Can you control speed with different loads on top of the cylinder? More specifically I need it to go at constant speed no matter the load or no load.

[@ubbeus]

rallo this is my need as well.

[@josephbrewington6729]

rallo just an idea but maybe you could use a servo to adjust the screw?

[@josephbrewington6729]

And perhaps use a PID controller and some way to sense the speed of the cylinder to automatically adjust the servo to move at the speed you want. Just an idea

[@abhishektyagi5974]

sir can you please tell me what air pressure are you using here and what is the piston dia? thank you

[@tecnoprofet]

Very impressive video . Congratulations. I’m new on the world of the pneumatic “toys”. I have some questions. What is your source of compressed air . How You adjust Newtons and stroke ( when is possible ) When system is “dead” , can you move still objects with hands ? What I need to complete system like this to close and open automatically a ......drawer ? Thank you very much.

[@garyklopper6976]

Hi Tecno, Compressed air would normally come from your compressor or a compressed air tank. You would normally use a regulator to adjust the pressure to the cylinder/actuator. If the system has no air in it you will be able to move the application manually as there is no air to restrict movement or keep your cylinder in one position. To open and close a drawer you will need a 5/2 valve Single Solenoid as in video an electrical switch to put power to the coil for activation and deactivation. piping and fittings. the size of the cylinder will be determined by the force required to open and close the drawer. You will probably need flow controls to adjust speed as shown in vid. If you don't want to use a solenoid type valve, you can use a pilot operated valve 5/2 pilot spring return and a 3/2 normally closed push button valve. This will do the same job.

[@adlerarmory8382]

Lucked upon this. Wanted to simulate the recoil of a dummy Mk19 40mm grenade launcher using pneumatics to move a chunk of oak inside that simulates the bolt mass moving inside a 1/8" thick aluminum housing, using a trigger activated controller programmed to extend/collapse the shaft at the same cyclic rate as the real weapon system 360-390 RPM, the shaft extending 5 inches each cycle, and possibly venting the air out the aluminum barrel. The original Mk19 has two captive action springs about 1" OD each so there is plenty of space to hide the cylinder.

[@Krysis219]

Does the cylinder lose force when it loses flow/speed?

[@brianzar1943]

Can you control the length of the stroke?

[@impressivemotorsports]

Can this be used for an air brake for a car?

[@josec8896]

How does this affect the operating pressure?(displacement force) I currently use a setup to move a box of 13 kg, however, it happens too fast. Thus, I want to use the speed control muffler to restrict the exhaust so that the box is slowly moved. Will it work, and will the pressure or displacement force remain the same?

[@jakubp4755]

The force should remain the same. Using a speed control muffler will only make the exhausting air take more time to exit the cylinder, but in the end the pressure there will be atmospheric.

[@facebookkhankhan4322]

Good teacher I like you

[@dcdc3973]

Anyone what kind of force these pistons can put out?

[@layiithalanai8147]

Thank you for your video, may I know what is the averaged air cylinder duty cycle?

[@FrightProps]

Cylinders do not have a duty cycle since they do not have an internal motor.

[@itsmisterchris]

Very nice

[@declanstewart17yearsago35]

How many pounds of force do these cylinders have?

[@radumotisan]

I'd need to understand more on your setup: how you control piston movement back and forth and what kind of air compressed source are you using. Also , what is the maximum force you can achieve with these pistons. Thank you

[@misteragb7558]

Does this affect the output force as well? Or only the speed?

[@michaelhead1879]

what if i want to keep the speed the same, but make it where i can reduce the force that it applies. I assume i turn down the psi but will this lower my speed also?

[@payasofeo69]

yes, speed is related to flow , force is related to the air pressure. set your pressure 1st and then adjust your flow control for the speed you want.

[@jibran4794]

The method you showed to control the speed using control valves... Does it compromise the pressure entering the cylinder?

[@garyklopper6976]

No it doesn't compromise the pressure. There is a difference between pressure and flow although they work hand in hand together. Lets say you need to move 3 pounds. your pressure is responsible for the work force to move that 3 pounds. Flow would determine the speed at which you move that 3 pounds. So you can have 30PSI @ 0.2 Cv or 30 PSI @ 0.4Cv Hope that helps

[@davec.3198]

Yup. Simply put....speed control controls speed....not force.

[@omaralbahri3206]

how can I know the force that I applied by the cylinder?

[@FrightProps]

Here is a document that can help with that: www.frightprops.com/faq/content/2/268/en/determining-cylinder-force.html

[@sjnsjn9663]

F=pressure×area

[@ammarahmed15]

How can i create a feedback control using pneumetic to move it certain positions

[@garyklopper6976]

Hi Ammar, Easiest way is to use a Positioner. They normally have a 4 - 20mA feed back or a 0 - 10 Volt. Positioner will only allow a certain percentage of air into the cylinder depending on the feed back signal.

[@buddha2845]

Can we reuse the exhaust air by connecting it to compressor inlet manifold? Will ir save some amount of electricity? Will ir be purified air? Someone has clue over this curious question?☺️☺️

[@petergeelmuydenmagnus4885]

If you limit the air pressure and the speed, you also limit the force, right?

only the air pressure affects the force of the cylinder
