Advanced Hydraulics Troubleshooting & Motion Control

Learn to:

  • Describe preventative maintenance procedures and list the steps in logical troubleshooting
  • Interpret cartridge valve (logic element) designs and schematics.
  • Explain the operation of transducers and perform basic tests.
  • Explain proportional valve principles and make basic adjustments.
  • Interpret ISO cleanliness codes and analyze oil test reports
  • Identify servo valve designs and make basic adjustments.
  • List the steps in safe testing of basic components.

Would an enhanced understanding of electro-hydraulics and complex pressure controls help you with your troubleshooting?

With the concepts in place from our level I & II courses participants are ready to tackle this intense level III course in advanced hydraulics topics. The emphasis is on understanding the internal workings and normal operating characteristics of complex hydraulic motion and pressure controls, making adjustments for proper operation and troubleshooting system problems. The electronics principles involved with proportional and servo valves are demystified for both mechanical and electrical maintenance workers.

The Ten Step Troubleshooting Process is taught with the goal of eliminating the hit and miss methods that can be so costly in terms of time and materials. Safety is stressed along with sound maintenance practices. The course is three days in length and is taught using a live hydraulics panel, simulation software, valve and component models and common test instruments.
