Workshop on Basic heavy equipment hydraulics fundamentals

Program overview

This class is designed to help students understand hydraulic principles and how they are used in the operation of hydraulic system components. Participants learn to identify the function of the various valves used in hydraulic systems and to identify the function of vane pumps, gear pumps, and piston pumps.

For Whom:

This program is designed for Diesel Engine Technician, workshop supervisors, field service engineers, preventive maintenance technicians and equipment maintenance advisors. Facility managers can equally benefit from this program.

Learning Objectives:

At the end of this program, participants will be able to:

• Explain basic hydraulic fundamental principles
• Explain the operation of the gear, vane, and piston pumps
• Identify the components and explain the operation of the simple relief valve, the pilot-operated relief valve, the flow control valve, the pressure reducing valve, the pressure differential valve, the check valve, the make-up valve, the sequence valve and the directional control valve
• Identify the components and explain the operation of single acting cylinders and double acting cylinders
• Identify and explain ISO hydraulic symbols
• Trace oil flow through ISO hydraulic schematics and explain operation of the pilot-operated implement system
