  1. Manual Control Systems: Pneumatics “A Slice of Mechanical Engineering” Mr. J. Butler ● Department of Technology & Engineering ● John Jay High School ● Wappingers Central School District

  2. Pneumatic Control Systems & EDD • DDP and POE • EDD: Animatronics are brought to life • Gaining experience in the area of manual arts • Engineering schools and labs

  3. Where are Pneumatic Systems Used? • Animatronics/Robotics • Transportation • HVAC (Heating Ventilation Air Conditioning) • Amusement Rides • Industrial Equipment

  4. Part I: Basic Pneumatic Parts & Equipment • Piston • Air Compressor • Tubing • Regulator Valve • Solenoid • Switch • Power Supply

  5. Piston • Known as Air Cylinder • Stores potential energy (compressed air) • Converts into kinetic energy as air expands to reach atmospheric pressure • Engineers prefer pneumatics since it’s cheaper, quieter, cleaner, and takes less space.

  6. Air Compressor • Using pistons and valves stores compressed air • Oil and oil-less models

  7. Tubing • Available in Difference sizes, and lengths • Used to transport compressed air from the Compressor • 1/4” and 3/8” Nylon Tubing is idea for EDD

  8. Regulator Valve • Controls the pressure of air • Measured in PSI (Pounds Per Square Inch) – unit of pressure • 30-60 PSI for EDD • Can be controlled from compressor or can be added to pneumatic air lines

  9. Solenoid • Electromechanical Switch • Control air flow • Open or Closed • Uses coil and slug to control air

  10. Switch • Electrical device • Breaks or completes electrical circuit • Powers the Pneumatic Solenoid Valve • Push Button

  11. Power Supply • Powers the Switch to Solenoid Valve • Controls air flow • Follow Safety Guidelines

  12. Observations • What makes the grave jumper work? • Moving Parts • Sounds • Range of Motion • Speed • Pressure

  13. Questions and Further Knowledge • Mechanical Supply Companies • Granger • DigiKey • Mechanical or Electrical Engineer • Web Resources • Library
