Setting up a new pneumatic system

by Mike Peterson
(Middleton Wi USA)

I am currently working on a machine to fold boxes.

I have mounted a double acting air cylinder with flow controls to fold the trailing flap.I have a good air supply.
How do I trigger the air cylinder to extend when the box is in place?

How do I trigger the air cyliner to retract when the box is gone?

If possible I would like to do it all with air.

Hello Mike, nice to hear from you.

There are quite a number of ways to sequence your air circuit using an all-air system.

What you need is a circuit designer, and I'm certainly willing to step up to the plate for you. Contact me through the contact page, give me your contact info, and I'll send info.

Cheers,

Bill

Water issues in my compressed air plumbing.

i drain my stand up air compressor about 3 times a day, while I'm using it to run a bead blaster. i will run it for about ten mins and the bead blaster will spray WATER through the blasting nozzle! do i need an air dryer for the compressor? i have a really big job on the go and need my compressor running properly, pleases help!

Howdy Tim. Nice to hear from you.

Your blaster uses a ton of compressed air. If you want to know why, click on the Compressor Water button on the navigation bar and read those pages.

Simply put, you're not draining your tank often enough, you may have some condensation occurring in your air line, and you don't seem to have a compressed air line filter installed to take out the free water.

As noted on the pages of the website, air preparation is a continuum. You keep adding equipment until you get your compressed air at the dryness and cleanliness level you need for your application.

If you have no filter at the outlet of your tank, install one, sized appropriately, there.

Did that do the trick?

For a short term (although it might be the most expensive to try) crack open the tank drain valve just a hair so that it bleeds continuously, to see if you get the water out sufficiently that way.

Did that work?

If neither of these do the job, install an auto drain that voids the tank more often, and start looking at air dryers. Information on these are found on this website too.

Cheers,

Bill

air leaks

What happens to compressed air if there pipe air leaks?






Bill says...

Hello there. What happens? The air loses its stored energy and goes back to atmospheric pressure.
