| Summary |
|---|
| Students will deal with function, structure, properties and applications of hydraulic mechanisms in the subject "Hydraulic Mechanisms". The subject is divided into the following sections: hydraulic circuit, properties of working liquids, basic calculations of hydraulic mechanisms, elements of hydraulic systems, their construction, function and characteristics, accessories of hydraulic circuits, hydraulic and pneumatic drives and transmissions incl. ways of their control, application of hydraulic mechanisms. The exercise is focused on calculations of hydraulic mechanisms and laboratory exercises. |
| Learning Outcomes of the Course Unit |
|---|
| Students will acquire basic knowledge of hydraulic elements and systems. They will be able to identify individual elements of the system, explain their meaning and function. They will be able to design and assemble basic hydraulic circuits. |
