Subject aims expressed by acquired skills and competences

Students will acquaint with systems and methods of maintenance and they will be able to compare and evaluate them, they will acquaint with assembly principles, actuation and operation and maintenance of hydraulic and pneumatic equipment. They will learn principles of labour protection with high-pressure equipment and they will be able to ensure safe operation of equipment by these principles application. They will acquire also needful practical knowledge by practice form in assembly and service organisations. They will learn in practice methods of measurement and evaluation of cleanness for working liquids and ways of filtration and temperature stabilisation.

Summary

In the introduction, students will acquaint with serviceability as complex property influencing product quality. They will examine gradually next properties: operational reliability, durability, maintainability, repairability etc. and methods of their evaluation. Students will acquaint with maintenance systems, maintenance methods, actuation, operation and maintenance of hydraulic and pneumatic equipment, functional and pressure tests and principles of labour protection with high-pressure equipment. They will occupy specially by liquids of hydraulic systems, cleanness of liquids, methods of filtration and temperature stabilisation. They will visit assembly and service organisations and test rooms in near firms in terms of practices.
