Hydraulics Training

HY142 - Hydraulics Level 3 - Maintenance, Fault Finding and Troubleshooting

A large percentage of spare parts sold for hydraulic plants and machinery are used to replace defective components. Most of these defects can be traced back to improper operation or maintenance. These mistakes and bad practices could cost hydraulic users hundreds of thousands of rands annually.

This course will teach maintenance staff how to avoid this situation, reduce operating costs and increase the uptime of hydraulic equipment.

Target Group: The course is for anyone exposed to hydraulics maintenance in their practical work.

The content includes:

• Hydraulic equipment maintenance - why it’s so important.

• Maintaining fluid cleanliness.

• Maintaining fluid temperature and viscosity within optimum limits.

• Managing hydraulic system settings to manufacturers’ specifications.

• Scheduling component change-outs before they fail.

• Following the correct commissioning procedures.

• Conducting failure analysis.

• The actual cost of hydraulic fluid leaks.

• Fluid contamination and dealing with water in hydraulic fluid.

• Troubleshooting basics and how to avoid costly mistakes.

• Symptoms of common hydraulic problems and their causes.

• Locating internal leakages.

• Fundamentals of hydraulic components and cylinder repair.

After completing this course, the participant will be able to:

• Describe how fluid contamination destroys hydraulic components.

• Determine appropriate fluid cleanliness for different types of hydraulic systems.

• Achieve and maintain appropriate fluid cleanliness continuously.

• Identify and rectify abnormal contamination load.

• Follow proactive maintenance routines that will save large sums of money.

• Know how to prevent damage to hydraulic systems caused by low fluid viscosity.

• Define operating temperature limits based on fluid viscosity values that maximise component life.

• Identify and rectify abnormal heat load.

• Identify faulty circuit protection devices before they cause component failure.

• Know when to schedule hydraulic component change-outs to minimise operating costs.

• Know what to do when installing hydraulic components to avoid reduced service life.

• Identify and name the causes of common hydraulic problems and how to locate them.

• Apply special techniques for troubleshooting simple hydraulic systems.

• Recognise and avoid costly troubleshooting mistakes and get the correct diagnosis.

• Carry out effective repairs on hydraulic cylinders and components.
