Interest Approach

Can you explain how air makes a pneumatic hand tool work?

Pneumatics Any system that uses a gas to create motion.

Generally, pneumatics uses air as the power source.

Parts of a pneumatic supply system

1) Motor

2) Compressor

3) Oil filter

4) Safety filter

5) Safety valve

6) Air storage tank

7) Pressure limit switch

8) Pressure regulator

9) Pressure system

10) Gauge

11) Manifold

12) Needle valves

Parts of a pneumatic system

Motor – converts electricity from the wall outlet into rotary motion

Compressor – takes in air from the atmosphere and pushes the air into a storage tank

Air filter – removes the dirt from the air

Safety filter – secondary device for removal of dirt

Parts (continued) Safety valve – allows extra air to escape

Air storage tank – holds a supply of pressurized air

Pressure limit switch – detects the presence of the air in the storage tank

Parts (continued) Pressure regulator – controls the pressure of air

Pressure system gauge – shows the pressure of the air

Flow meter Measures the amount of air flowing through a pneumatic circuit.

Measured in standard cubic feet per hour (SCFH)

Pneumatic safety practices Always wear safety glasses or goggles

Keep all body parts and loose objects away from operating cylinders

Always close the needle valve on the manifold before changing a pneumatic circuit

Safety practices (continued)

Always read the directions completely before working on any pneumatic system

Handle all electrical components and fittings carefully
