Proportional hydraulics and pump controls

‘Proportional hydraulics and pump regulation’ is the third step in our series of hydraulics courses. It’s designed to expand and upgrade your machine-maintenance skills. To participate, you must have already successfully completed both ‘Introduction to mobile hydraulics’ and ‘Hydraulic diagram reading’. In this 3-day course, you’ll learn how different hydraulic components function, such as proportional valves and load-sensing pumps. You’ll find out how to perform adjustments on machines with proportional valves and load-sensing pumps, and also how to perform diagnostic tests on machines equipped with these new technologies. Plus, you’ll have the opportunity to try out your new skills in a practical setting, so you’ll be prepared to put what you’ve learnt into practice.

TARGET GROUP

Engineers who want to keep up with and explore the modern complex systems of hydraulic controllers and drives.

PRIOR KNOWLEDGE

Familiarity with the maintenance of machines as an engineer. Participants must have taken and successfully completed the training courses ‘Introduction to mobile hydraulics’ and ‘Hydraulic diagram reading’.

GOAL

To get to know and understand the functioning of the different hydraulic components in the mobile hydraulics, such as proportional valves and load-sensing pumps.
To be able to perform adjustments on machines with proportional valves and load-sensing pumps.
To be able to perform a diagnostic test on machines equipped with these new technologies.
