SYSTEME FÜR DIE TECHNISCHE AUSBILDUNG
EQUIPMENT FOR ENGINEERING EDUCATION
planning of piping and system installations according to specification
reading and understanding engineering drawings and technical documentation
operational testing of the constructed systems
familiarisation with various alignment methods: straight edge, dial gauges
Main concept
The laboratory is designed for accommodation of 24 students + 2 laboratory staff:
2 - 4 students form a team and work together at a workstation / training system
15 workstations of 14 different types
Each experiment base unit is floor standing or on a laboratory table
Each workstation is equipped with a manual containing technical information, basic theory,
experiment instructions, evaluation help and safety advice.
Student teams are scheduled to change workstations from lab session to lab session in order
to perform the entire range of experiments within the course duration.
Average time per experiment: 90 to 120 minutes.
2 workstations for laboratory staff (with PC and internet access)
1 printer for common use
1 cupboard for small parts, consumables, tools, paper etc.
1 large shelf for the storage of unused experiment accessories
Initial training provided for laboratory personnel
Trainer: Specialized engineer of G.U.N.T. Gerätebau GmbH, Germany.
To be conducted immediately after installation and commissioning of the equipment.
General topics to be covered for any of the educational systems:
Basic familiarization with the system.
Functions and components.
Overall system configuration aspects.
Start-up and operational aspects.
Conduction experiments, including evaluation and calculation.
Using the system with and without the software (where applicable).
Trouble shooting and maintenance aspects.
Hands-on, practical familiarization aspects.
Seminar participants with the delivered system.
Details of the manuals.
Safe operation and preventive maintenance.
