Pneumatic Control Circuit Simulation using Fluidsim
Pneumatic cylinder is a mechanical equipment that is quite popular in the manufacturing industry. This is because pneumatic cylinders are the backbone in the development of industrial automation today.
The main components of a pneumatic actuator include end caps, pistons, piston rods, cylinder strokes, wiper seals and bearing sleeves and seals. In a simple circuit, a single acting pneumatic actuator can be operated with a button. When this button is pressed, air moves the piston rod outward.
Because i used double acting pneumatic type with single rod, for the solenoid valve i used a dual coil solenoid for the cylinder. The choice of pneumatic actuator and cylinder type can affect the final movement.
Materials :
- Double-acting cylinder
- 5/2 way DCV
- One way flow control valve
- Air supply unit
For the actuator I used a double acting cylinder with a single rod, this type of cylinder has two intake ports. One for the extended stroke and one for the return stroke. This type of cylinder does not use a spring. The choice of this cylinder is tailored according to the needs of the industry. In the event of an emergency, when the air supply to the compressor is interrupted, this double-acting cylinder does not return automatically, but remains in place. See image below for details.
Scenario :
I used Fluidsim-P for this simulation. It works simply, just use the ON button and the pneumatics will move the bar one cycle (extend and return the stroke).
We can use a solenoid valve to adjust the rod opening size. The larger the opening, the faster the rod moves, and the smaller the opening, the slower the rod moves.
Next we arrange the electrical diagram. The power source is from a 24 Volt power supply, then a push button to switch ON and OFF. And of course relays and contactors for connecting and breaking.
What you need to pay attention when working with pneumatics cylinder is the quality of the supplied air. It should be clean and free of water or oil. In addition, regular maintenance is required, such as cleaning the toner cartridges or lubricating the cylinders.
