Pneumatics



Pneumatic systems use the energy stored in compressed air to do work. By controlling the release of the air to pneumatic cylinders, we can turn that energy into movement.

Pneumatic components are arranged in circuits – much like electronic circuits – using symbols for each component. You need to be familiar with the operation of two of most common pneumatic components – a single-acting cylinder with a three-port valve, and a double-acting cylinder with a five-port valve. You also need to understand how time-delayed pneumatic circuits and pneumatic logic circuits work.
Finally you need to know how to work out the force output from a cylinder.

The equipment used in the building of pneumatic circuits in school are:

Three prot valve (3PV)

Five port valve (5PV)

Single acting cylinder (SAC)

Double acting cylinder (DAC)

The building boards

Safety
It is essential to follow these rules when dealing with pneumatics as there is high pressure from the compressor.

 

Why use Pneumatics?paint56ed

  • Operations can be repeated without operator fatigue.

  • Cost effective.

  • Operated safely in hazardous environment.

  • Consistant quality of work.

As can be seen from the picture above the car body is being sprayed using a robotic arm.  This robot can work in an environment where people would need to wear protective clothing and could not work there for a long time, this robot could work 24 hours per day.
