Mechanical Systems

30 Hours

This course is divided into four sections, and is intended to provide the student with a basic introduction to selected mechanical systems, system application, and the fundamental principles of operation and maintenance of these systems. The course sections are as follows:

Bearings (8 Hours): This section will cover the types, purpose, maintenance, and replacement of bearings. Troubleshooting techniques and procedures will be covered.

Gears and Drives (6 Hours): This section will include gear types (spur, helical, worm and bevel) and drive/drivetrains (chains, belt and disk), their application and use, and maintenance.

Lubrication (6 Hours): The properties and effects of friction will be explained. The characteristics, use, and application of lubricants and lubrication systems to reduce friction will be covered, as well as viscosity and additives. Lubrication work safety will be addressed.

Pumps and Compressors (10 Hours): This block of instruction is sub-divided into Pumps (5 hours) and Compressors (5 hours). The sub-section on Pumps will include an explanation of basic hydraulics and pump fundamentals and liquid handling principles. Other topics to be covered are pump types, pump selection (head, capacity, pipe systems, drives), and pump applications.

The Compressor sub-section includes instruction on air conditioning compressors, self-contained units, central chilled water, water cooling towers, and water treatment. Air supply systems and filters will be explained. Preventive maintenance and safety will be covered.
