About Air over Oil systems

by John

Mr. Wade, I am considering converting several pneumatic cylinders in my woodworking plant to air over oil hydraulic types.

I read your excellent summary article and wonder if you supply the components needed for the conversion, namely the air/oil tanks and new flow controls.

If not, can you recommend a supplier? Thank you, JR






Hello John...thanks for your question and your very kind comments.

For those that haven't read my "excellent summary article" :-), an air over oil system uses compressed air to move incompressible oil through lines to the cylinder, and the use of flow controls in those lines imparts a smooth, hesitation free stroke speed to the cylinder rod.

John, your return email address suggests you're in Washington somewhere.

They won't remember, but over the years I have some dealing with these folks..

Airdraulic Division Fluid Power Inc: Arbts
- www.fluidpowerinc.com
10451 Mill Run Cir, Owings Mills, MD - (410) 646-1545

...and as I recall, they were knowledgeable and professional.

If they aren't near you, call them anyway, and they should be able to give you an idea about a fluid power supplier in your area.

Sorry, I can't sell them to you.

Regards,

Bill

about speed of action of the pneumatic cylinder

by angelo paglinawan
(philippines)

Sir Bill:

i would just like to know if it is possible to make the action and retract of the cylinders faster enough so as to cause such an impact load/force needed for the machine.

i'm talking about the larger cylinders, 2.5 inches in diameters here.

i'm new to this field and it'll be a great work in my project this time.

thank you and more blessings!

Best regards,
Angelo

It would be good, Angelo, if you provided a lot more information about the application.

You say you want to "make the action and retract of the cylinders faster enough so as to cause such an impact load/force needed for the machine"?

Air cylinder speed is governed by the Cv of the valve, the size and length of the air lines between the valve and the cylinder, and on the sufficient flow of compressed air supply to the valve.

See the section on "Quick Exhaust" for a specific item that will increase cylinder speed.

Hope this helps,

Bill

Hi Ray:

If you contact your local fluid power supplier, they will be happy to specify the linear actuators, and if you ask, they may be able to design the air circuit for you. The latter service may or not be charged for.

I can do it for you as well, but that's the part of my service that I don't give away.

Cheers,

Bill
