Pneumatic Maintenance

Course 1: Pneumatic Principles

Prerequisites: This lesson is designed for participants familiar with test instruments and devices.

Description: This lesson introduces the principles of pneumatic instrument operation and the terms force, pressure and compressibility are defined. The operation of pneumatic air supply system components, including compressors, dryers, filters and regulators is explained. System maintenance and testing is also taught. Filter cartridge replacement and regulator maintenance is demonstrated.

Objectives:

• Define force as it applies to pneumatics
• Define pressure as it applies to pneumatics
• Define compressibility as it applies to pneumatics
• State Pascal’s law as it relates to pneumatics
• State Boyle’s law as it relates to pneumatics
• State Charles law as it relates to pneumatics
• State the ideal gas law as it relates to pneumatics
• Discuss how and why pneumatics are used in the industry
• Describe why pneumatic instruments have a limited transmission distance
• Describe the purpose and operation of a booster
• List the effects of contaminants on a pneumatic system
• Identify types of filters and how they aid in removing suspended material in an air supply system
• Prepare a filter for disassembly
• Dissemble a fitter
• Clean a filter
