| Summary |
|---|
In the subject "Fluid Mechanisms", students deal with function, structure, properties and applications of fluid, i.e. hydraulic and pneumatic mechanisms. The subject is divided into the following sections: general introduction, basic calculations of fluid mechanisms, elements of fluid systems, their construction, functions and characteristics, hydraulic and pneumatic drives and transmissions, including ways of their control, application of fluid mechanisms. The exercise is focused on calculations of fluid mechanisms and laboratory measurements.
|
| Learning Outcomes of the Course Unit |
|---|
Students will learn the basic concepts of fluid mechanisms: hydraulic mechanism, pneumatic mechanisms, hydraulic and pneumatic circuit. Become familiar with the composition of hydraulic and pneumatic circuits, basic hydraulic and pneumatic components, their functions, structures, characteristics using the circuit. Students will learn to count instances hydraulic and pneumatic circuits in steady state and solve the starting and braking hydraulic actuators. Learn to design simple hydraulic and pneumatic circuits and compile them on trainer in the laboratory. Students acquire basic knowledge of the operation, maintenance, measurement and diagnostics of hydraulic and pneumatic equipment.
