Hydraulics Workshop: Hydraulics & Basic Electrical Applications On-Site Training

This 4-day classroom course is will teach you both about Hydraulic Systems and the Electrical components that power them.

Course Description/Agenda

This 4-day classroom course is will teach you both about Hydraulic Systems and the Electrical components that power them.

First - Learn how to keep fluids positively confined through the entire system and prevented from going anywhere except where you want them to go. Properly constructed hydraulic systems possess a number of favorable characteristics. Increase your knowledge of basic hydraulics and become a better troubleshooter, which helps increase productivity, decrease downtime and maintenance costs.

Then - Gain a basic understanding of electricity generation and delivery. Learn how electricity is applied to transformers, motors and common electrical devices; how and where these components work and their applications. You will also learn and practice safe methods and how to choose the proper instruments and tools to measure and comprehend the characteristics and properties of electrical signals in terms of voltage, current and impedance (resistance).  Gain invaluable experience in using and understanding electricity and its function in an electrical circuit. The course covers all aspects of electricity, including ohm?s law, terminology, common circuits, test equipment, safety, generators, motors and relays. Theory and explanations support numerous practical hands-on exercises, and can apply to real world situations.

The full course content is for apprentices, machine operators, mechanics, technicians, supervisors and other trades people. Its benefit is being able to find, understand and fix electrical problems more easily, thereby reducing downtime.

NOTE   This is not an "electro-Hydraulic" course.  It does not address proportional or Servo valve technology.
