Pneumatic 1

  1. 1. PNEUMATIC Understanding the basic of pneumaticAditya@poltekom.ac.id
  2. 2. Definition• Pneumatic is a system / tools that is worked basically using the air pressure / air flow• Therefore the force / work / displacement generated based on the general law of air pressure and flow• Pneumatic is an actuator using the air pressure as their source of power
  3. 3. Comparison Pneumatic ElectricAir pressure Power source Electric currentDirectional valve Controller component TransistorsSlow Signal delivery Faststrong Energy conversion Weak
  4. 4. Comparison Pneumatic ElectricCylinders Motors, linear motorDirectional valve Transistors/contactorsLogic valves Op ampsButton valve Button / switchAir pressure Battery
  5. 5. WORKING ELEMENTS / ACTUATING DEVICES Single / double acting cylinder
  6. 6. SINGLE ACTING CYLINDER Forcible surface Spring return DEpressurized chamber Pressurized chamberAir pressure port Exhaust port / / supply port waste port
  7. 7. SINGLE ACTING CYLINDER Forcible surfaceAir pressure port / supply port
  8. 8. DOUBLE ACTING CYLINDER Forcible surface Spring return DEpressurized chamber Pressurized chamberAir pressure port / supply port Air pressure port / supply port + Exhaust port / waste port + Exhaust port / waste port
