Tutorial 4: Pneumatic circuits
In this tutorial you will:
- Get in touch with pneumatic components.
- Make and modify connections between component ports.
- Play with different configurations using the given components.
Start by loading the tutorial system into the workspace, and then navigate through the components in the tree and the scene to explore them.
To be able to follow this tutorial, make sure you have already done the Basic Tutorial 1.
The system includes an assembly consisting of a table with a compressor, a single-acting cylinder, a double-acting cylinder, two manual 3/2 way directional valves, and a manual 5/3 way directional valve.
Build a basic circuit
The first basic circuit you are going to build is the one represented in the diagram below.
The pneumatic compressor 'COMPRESSOR' will be directly connected to the single-acting cylinder 'C01'. 'COMPRESSOR' has a pneumatic output port called 'out', and you will connect it directly to 'C01' input port 'p1'.
The basic circuit is now ready to test. We should expect that the cylinder will expand when the emulation is started. Click on start and see if it works.
You can inspect the 'COMPRESSOR' and 'C01' port values to see that the values are transferred.
In the case of pneumatic ports, both 'pressure' and 'flow' are represented in international units.
If you reset the emulation the components will be reset and the cylinder will go back to its retracted position.
Modify the circuit
Make sure you have paused or reset the emulation before you continue so you can modify the system.
Now we are going to add the 'Y01' 3/2 way directional valve to the circuit, between the 'COMPRESSOR' and 'C01' components so we can manually activate the cylinder when we press the pushbutton on the valve.
Set the 'COMPRESSOR.out' port to the 'p1' input port of the 'Y01' valve and you can leave the 'p3' port on the air like in the diagram. Then set the 'C01' input port 'p1' to the output port 'p2' of the 'Y01' valve. 'Y01' port connections should look like the following:
If you emulate the system now, you can press the button on 'Y01' and 'C01' will expand. If you release the button, it will automatically retract.
Time to play!
Now it is time to play and build your configurations using the different cylinders and valves you have in the system.
Here you have some examples:
If you emulate the system now, you can press the red spheres on the sides of the 'Y03' joystick to move it left or right.
