A "hands on" course that covers the following:

Identification of both tools and materials used in pressurization

OHMS Law of Air Pressure (pressure-flow-resistance)

Leak Locating Formulas

Graphing

Locating Leaks with Helium

On an optional fourth day, the class moves from the classroom into the field for helium leak locating and actual hands on work

This "hands on" course covers:

Why Air Systems?

Introduction to Air Dryers (what is: air, moisture, dew point, air volume and how they relate)

Air Dryer Information (capacity, sizing, location and electrical requirements)

Basic Sections of a Dryer

The workings of water-sealed, oil-less piston/heatless compressors

Routine maintenance

Trouble shooting

During the class the students will be divided into groups for the hands on portion of the course which includes:

Rebuilding water sealed and oil-less/heatless compressors.

Testing procedures

Troubles will be placed in both types of dryers for the hands on, troubleshooting portion of the class

This course covers the methods and procedures for proper buffering operations in pressurized sheath.

The students are informed of the importance of buffering which requires a full understanding of cable resistance and how flow rate effects where buffering should take place. The Air 1 practice simplifies the buffering procedures once the cable resistance and flow rates are understood. It also has numerous example sketches of proper buffering techniques.

Ohms Law of Air pressure. Technicians require a full understanding of how resistance effects their leak locating procedures. 

Identification of tools used for helium leak locating (regulators, flow raters, helium flow controller and detectors).

Proper hookup to air source (air pipe / distribution panels or an individual cable) in the Central Office and/or buried cable in the field.

Procedures used to find helium in aerial, buried and/or underground cables.

Go to selected Central Office and/or buried cable location to set up helium for the following day exercise.

Locate leaks with procedures learned the 1st day.

There are two (2) courses available: The first is an overview of the engineer’s responsibilities and the second is a training course which includes hands-on examples. The training course is designed to accomplish three major objectives.

• Familiarize the student with the component parts and purpose of an air pressure system.
  
  
• ·Teach the student air pressure engineering concepts and the process of identifying how different engineering situations affect the air pressure system.
  
  
• ·Improve your ability to successfully interact with the existing air pressure system as you submit engineering jobs. This will be accomplished through the use of hands-on problem solving that will stress maintaining the integrity and maintainability of your air system
