Interactive Lab Assistant: Electrohydraulics

The test instruction is an interactive lab assistant course. This multimedia course extends the topic of hydraulics into electrohydraulics. Electrotechnical basics are conveyed through easily understandable animations. The interactive lab assistant forms an extensive experimental environment together with the question section.

special features:

• interactive test setups
• measured values and graphics can be saved in the test instructions via drag and drop
• questions with feedback and evaluation logic for knowledge status control
• print document for convenient printout of the test instructions with solutions
• Course software

learning content:

Occupation-specific specialist qualifications, e.g. the manufacture, assembly and disassembly of assemblies and systems, should be taught integrated with core qualifications, e.g. the planning and organisation of work and the evaluation of work results. business processes and quality assurance systems in the area of application are, among other things, learning contents of the occupation-specific technical qualification.

In detail:

• be able to understand physical laws and technical relationships (surface, pressure, force, work and performance)
• be able to explain hydraulic devices in terms of function, design, practical mode of operation and possible applications
• be able to read and understand circuit symbols and circuit diagrams
• know the basic controls of the hydraulics and be able to assemble assemblies according to circuit diagrams that have been worked out
• know the types, properties, requirements and applications of hydraulic fluids
