Credits 6
Hours 48
Period II
Language ENG

Prerequisites
Mathematical analysis, Physics, Applied mechanics, Machines

Learning outcomes
The course aims to provide the student with knowledge of the main components of hydraulic and pneumatic circuits. On completion of the course the student will be able: - to understand the specific use and application of a component; - to understand the functioning and capabilities of a circuit; - to select the most appropriate component or plant for a given application.

Program
IGeneral principles. Hydraulic energy transmission. Head and fluid loss. Hydraulic fluid classification. Physical and chemical characteristics. Graphic symbols and standardisation. Hydraulic open and closed circuits. Pumps and engines with pistons, blades, gears. Hydraulic jacks. Geometrical displacement. Formulas for performances computation. Pressure regulation valves. Pressure reduction valves. Sequential valves. Flow regulation valves. Flow limitation valves. Flow dividers. Overcenter valves. Direction regulation valves. Non-reversal valves. Rotary and case distributors. Feeding groups. Utilizing groups. Parallel, in series and mixed circuits. Circuits for sequences. Hydrostatic transmissions. Load sensing systems. Fitting elements for circuits. Compressors. Compressor and tank choice. Pneumatic jacks and hammers. Pressure, flow, direction regulation valves. Analytical and graphic computations examples.

Development of the examination
LEARNING EVALUATION METHODS
The assessment of the level of learning and understanding consists of two parts: 1 - written test containing four questions related to the topics covered in the lectures 2 - oral clarification and/or deepening of the themes of the written test, if necessary, by adding an additional problem of theoretical and/or application nature.

LEARNING EVALUATION CRITERIA
The student has to demonstrate to have understood and acquired the physical principles and theoretical considerations on the basis of the configuration and operation of power systems and components in the technical field of hydraulics and pneumatics. The responses also include the quantitative knowledge of the topic.

LEARNING MEASUREMENT CRITERIA
Attribution of the final mark out of thirty. The final evaluation results from the weighted average of the pre-trial written examination (25%) and oral (75%). To pass the exam both tests should be sufficient.

FINAL MARK ALLOCATION CRITERIA
In order that the final outcome of the evaluation is positive, the student will have to prove that he has no gaps on basic skills covered in the course. The highest rating is achieved by demonstrating in-depth knowledge of the course content. Praise is given to students who, having done the pre-exam and oral fairly and with good level of detail, have also shown a particular brilliance in exposure and/or have demonstrated particular mastery of the material knowing also the use of the acquired skills to analyze topics not explicitly covered or treating the topics in a way alternative to the proposed one.
