| Course abstract | |
| The aim of the study course is to explain the basics of the hydraulic and pneumatic drive of the machine. Students acquire the functional significance of the elements of the hydraulic and pneumatic systems, their design, operating principles and parameters, as well as the basic conditions and methodology for designing these systems. Theoretically and practically, the management of hydraulic and pneumatic systems, control options and diagnostic methods are mastered. | |
| Learning outcomes and their assessment | |
| Knowledge - Understands the basic rules of fluid mechanics, the construction and operation of static and dynamic equipment and machines, the constructive design and operation of pumps and compressors together with the pipeline network. Determine the application possibilities of hydraulic and pneumatic drive systems - Laboratory works.
Skills - you can evaluate the laws of equilibrium and motion of fluids from the engineering point of view, which operate in fluid containers, pipelines and openings through which the discharge takes place, as well as orientations in schematic drawings of hydraulic drives and pneumatic drives. Evaluates the static and dynamic functioning of hydrosystems, understands the functions, applicability and operation of the apparatus used - Laboratory works. Competence - Designing hydraulic drives for various machinery and machinery members for appropriate operating conditions. Resolves issues of hydraulic drive and pneumatic drive maintenance to ensure non-refoulement - Laboratory work. |
