| Course abstract | |
| In the study course on the theoretical basis of fundamentals laws balance and movement laws and regimes of liquids as well as structure, operation and calculation methodic of essential parameters of hydrostatic and hydrodynamic machinery are explained. During studies construction, dynamical sense and operation principles of basic hydraulic aggregates and adjusted equipment as well as acquirements and calculation methodology of designing of hydraulic drive according to technological requirements are uptake. Adopt Fluid SMS. | |
| Learning outcomes and their assessment | |
| 1. Basic knowledges of fluid mechanics laws – Test 1.
2. The ability to evaluate fluid balance and the laws of motion, operated in liquid filled vessels, pipelines and flow through orifices, nozzles and jets in dependence of flow regime – Test 2. 3. Understands the structure and operation of static and dynamic equipment and machines, the construction and operation principles of the pumps together with the pipelines network. The construction, operation and applications of volumetric and dynamic hydraulic equipment – laboratory work. 4. The ability to analyse hydraulic and pneumatic circuit diagrams, understand the functions, applicability and operation of the apparatus used in the scheme – laboratory work. 5. Developed competencies for design and management of hydraulic and pneumatic drive systems of different mechanisms. Capacity to solve the technical issues relating to maintenance and operation of non – refusal hydraulic and pneumatic drive systems is provided – practical work. |
