Course content
|
The course is intended to give students a good insight into the following areas: basic components, principles and calculations; generators and motors, power control components, accumulators, multipliers; their characteristics, use and structure; efficiency; elementary parameters of energy media, especially oils; cleaning, packing and cooling of fluids; effects of gas on the behaviour of hydraulic circuit mechanisms, placing and linking of components; control of motor speeds, hydrodynamic shock, dynamics of hydraulic mechanisms, hydraulic and pneumatic moving seatings; design of hydraulic circuit functional diagrams. 1. Organization of the course. Importance of the subject for the practice. Definition of the power fluid mechanism (PFM, it's structure. Fundamental equations. Introduction of the PFM. Advantages and disadvantages of the PFM. Classification of PFM according to energy carrier and technological requirements. 2. - 5. Pneumatic and electropneumatic systems. Pneumatic elements, classification, applications. Graphical symbols of fluid system components. Principles of function of the selected pneumatic and hydraulic elements. Rules for creation of diagrams for hydraulic and pneumatic circuits. Pneumatic circuits creation. 6.-8. Practical tasks - connecting of pneumatic circuits (FESTO Didactic, SMC Pneu panel). Electropneumatic circuits - fundamental circuits, logical functions, combinational and sequentional circuits. Control of electropneumatic circuits. Combinational and sequentional circuits. Programming PLCs via functional blocks. 9. Selection and dimensioning of elements of pneumatics and electropneumatics circuits. 10. Fluid based transmission systems. Open and closed hydraulic circuits (HC). Hydrogenerators (HG) and hydromotors (HM). Transmission systems according to the HM motion. Energy carriers and their main parameters. Loading of fluids, requirements and proper selection. Seals and gaskets, cleaning. Fluid properties. Energy transfer by means of fluids. Distribution of pressurised fluid in the HC. Tanks.
