Course Introduction

Our Fundamental Hydraulic Theory and Maintenance course is designed to equip delegates with the basic foundation knowledge and building blocks that underpin all hydraulic systems. On completion of the course, delegates will receive a broad-base knowledge of hydraulic equipment and will be able to identify symbols and components used in schematic drawings. They will also understand the importance of cleanliness levels, good safety practices and best practices in fault finding techniques and procedures to reduce costly downtime. The course also provides delegates with a greater working expertise and understanding of fluid power systems.

Course Objectives

  • How the basic hydraulic theories are applied in practice

  • The importance of good hydraulic filtration techniques

  • The operation of pressure, flow and directional control valves and the applications in hydraulic circuits

  • Hydraulic pumps and motors and the control thereof

  • Hydraulic cylinder construction and good sealing practices

  • Basics of Fluid Power connectors and hose assemblies, good practice techniques and the different threads found in hydraulics

  • The basics of hydraulic circuit applications

  • The different types of hydraulic control systems and the effect on energy usage

  • Maintenance and troubleshooting techniques

Who should attend?

Those involved in troubleshooting industrial hydraulic equipment at industrial plants, utilities or commercial and private building facilities.

People who will benefit from attending this course include:

  • Plant Managers

  • Maintenance Managers & Personnel

  • Filtration, Maintenance & Design Engineers

  • Millwrights, Pipe Fitters, Plumbers, Mechanics, Machinery Maintenance Mechanics and Electromechanical Repair Technicians

  • If you are responsible for the ongoing operation of a fluid-power system, or if you manage or train workers who are. This course can show you what you need to know to keep the systems up and running.
