Workshop on Fluid Power Systems: Hydraulics and Pneumatics

This course provides participants with the knowledge to construct and operate all the individual components essential for the optimum operation of the overall fluid power system. It includes the supply of fluid (gas or liquid), the use of fluid powered control cylinders, control valves and motors as well as the tools associated with the maintenance and repair of fluid power systems.

For Whom:

This course is designed for professionals involved with, and responsible for, the operation of fluid power systems including maintenance managers, maintenance supervisors, engineers, project managers, technicians and plant operators.

•          describe the development and applications of modern fluid power systems (hydraulics and pneumatics) including the different types of fluids and the three general classes of piping;
•          apply Pascal's law to the design and operation of fluid power systems and circuits;
•          outline the types of seals and components in fluid power systems and their respective benefits;
•          operate a fluid power system circuit, given a system schematic; and
•          prevent, identify and troubleshoot common failures of fluid power systems.
