Air is fantastic and does really awesome stuff! Have you inflated a balloon but released it, only to see it fly around as it deflates? That behavior is quite similar to pneumatic cylinders. They use air to push machines to move in really cool ways.
What is a Pneumatic Cylinder?
A pneumatic cylinder as well as mini pneumatic cylinder is a magic tube with a special sliding part inside. Air is blown into the tube and the inner part moves backward and forward. How cool is that — a tube where a piece can slide in and out of it only with air? You know how you can blow and push a toy car? It’s kind of like that, only magnified!
Types of Pneumatic Cylinders
There are two main types of miniature pneumatic cylinder that perform different tasks:
Single-acting cylinders – There is only one hole for air to enter and exit. It’s like a straw that can only blow one way.
Double-acting cylinders: These have two holes so they can move in more directions. It’s like getting a deeper tube that’s easier to push and pull.
Choosing the Right Cylinder
Selecting the proper pneumatic cylinder is akin to selecting the proper device for a task. You need to think about:
How big it needs to be
How strong it needs to be
How far it needs to move
Where you will put it
You need the right hydraulic air cylinder for the right job, just like you wouldn't use a little hammer when building a big house!
How Pneumatic Cylinders Work
And by forcing air into the cylinder you create pressure. This force causes the internal component (known as a piston) to slide. It's sort of like inflating a balloon - the more air you add, the more it wants to go somewhere!
Maintenance of Pneumatic Cylinders
Here are steps you can follow to ensure proper maintenance of pneumatic cylinders:
Give parts room to move with special oil
Inspect for air leaks (small holes where air can escape)
This lets you know that you are well armed
Check on the cylinder frequently to ensure it's operating properly
Staying Safe
General Guidelines for Pneumatic Cylinder Care
Follow safety rules
Properly use personal protective equipment; e.g. have safety glasses
Movement parts be careful
If you’re not sure what to do, ask a grown-up for help
