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 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

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

11 Parts (continued)  Pressure regulator – controls the pressure of air  Pressure system gauge – shows the pressure of the air

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

13 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

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

15 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?

16 The End!
