  1. Lesson 8 Using Pneumatic Systems

  2. Next Generation Science/Common Core Standards Addressed? • CCSS.ELA Literacy RST.9 10.1 Cite specific textual evidence to support analysis of science and technical texts, attending to the precise details of explanations or descriptions. • CCSS.E L A Literacy RST. 11-12.1 Cite specific textual evidence to support analysis of science and technical texts, attending to important distinctions the author makes and to any gaps or inconsistencies in the account. • CCSS.ELA Literacy.RST.9‐10.3 Follow precisely a complex multistep procedure when carrying out experiments, taking measurements, or performing technical tasks, attending to special cases or exceptions defined in the text. • CCSS.E LALiteracy.RST.11‐12.3 Follow precisely a complex multistep procedure when carrying out experiments, taking measurements, or performing technical tasks; analyze the specific results based on explanations in the text

  3. Bell Work - Student Learning Objectives • Define pneumatics and explain the major parts of a supply system. • Describe the purpose of a flow meter. • Explain the safety practices for pneumatics.

  4. Terms • Air filter • Air storage tank • Compressor • Flow meter • Manifold • Motor • Needle valves • Pressure limit switch • Pressure regulator • Pressure system gauge • Safety filter • Safety valve

  5. Interest Approach • Can you explain how air makes a pneumatic hand tool work?

  6. Pneumatics • Any system that uses a gas to create motion. • Generally, pneumatics uses air as the power source.

  7. Parts of a pneumatic supply system

  8. 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

  9. 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

  10. Parts (continued) • Pressure regulator – controls the pressure of air • Pressure system gauge – shows the pressure of the air

  11. Flow meter • Measures the amount of air flowing through a pneumatic circuit. • Measured in standard cubic feet per hour (SCFH)

  12. 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

  13. Safety practices (continued) • Always read the directions completely before working on any pneumatic system • Handle all electrical components and fittings carefully

  14. Review/Summary • What is pneumatics and what are the major parts of the supply system? • What functions does the flow meter perform? • What safety practices are used in pneumatics?

  15. The End!
