Description
I have been providing in-person training and consulting for 46 years.

The training has helped many organizations resolve expensive downtime and ongoing maintenance costs. In addition to the course material, I will share some of my consulting experiences helping get plants back online and resolve ongoing maintenance costs.

Students from many countries have attended the courses including African states, United States, Emirates, Indonesia, and Europe.

The presentations include animated PowerPoint slides and demonstrations of hydraulic components.

Calculations are provided using metric units.

The course topics include:

Principles of Hydraulics

Compressibility of Hydraulic Fluid

Hydraulic Symbols

Two Cylinder Problem

Cleanliness of Oil

Cleanliness continued

Hydraulic and Mechanical Leverage

Design of Cylinders

Cylinders Oil Capacity

Cylinders in Parallel

Components of a Hydraulic Circuit

and Reynolds number

Hydrostatic Drives

Couplings and Reservoirs

Hose Identification and Couplings

Check Valves and Cartridge Valves

Pilot Operated Check Valves

Flow Control Valves

Pre-fill Valves

Directional Control Valves

Solenoid Valves

At the end of the course two lectures are provided covering field experience and safety ideas for hydraulic systems.

The course includes resources which can be downloaded for future reference.

An advanced hydraulics course is being prepared which will help engineers, draftsmen and foremen in the design of hydraulic systems.

Who this course is for:
Technicians responsible for hydraulic system maintenance and troubleshooting
Engineers responsible for hydraulic system design and troubleshooting
Artisans working and maintaing equipment
