Presented by the late Garnett Cross who was an industry leader in hydraulics.
Garnett provided in-person training and consulting for 47 years - 1974 - 2021. His clients included the major corporations in manufacturing, mining, military, shipping and rail.
The training has helped many organizations resolve expensive downtime and ongoing maintenance costs. In addition to the course material, Garnett 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
Two Cylinder Problem
Cleanliness of Oil
Hydraulic and Mechanical Leverage
Design of Cylinders
Cylinders Oil Capacity
Cylinders in Parallel
Components of a Hydraulic Circuit
Pipe sizes for 90 litres/minute
Pipe sizing with respect to turbulence of fluid
and Reynolds number
Couplings and Reservoirs
Hose Identification and Couplings
Check Valves and Cartridge Valves
Pilot Operated Check Valves
Flow Control Valves
Directional Control Valves
Solenoid operated valves with orifice
Externally piloted system with throttle plate
Gasket mounted relief valve
Sequencing cylinders with sequence valves
Sequence and pressure reducing valves
Over center valve with hydraulic motor
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 available, this 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
I have been training and consulting in the Maintenance and Design of Hydraulic Systems for over 45 years. Trained thousands of engineers and technicians who have successfully implemented the knowledge gained and saved on component costs and improved their systems and reduced downtime
I have consulted for mines, port authorities, and manufacturing industries, fault finding and system design.
