Hydraulic Machines (FSI-FHY-A)

Academic year 2020/2021

Supervisor:	doc. Ing. Simona Fialová, Ph.D.
Supervising institute:	EÚ	all courses guaranted by this institute
Teaching language:	English
Aims of the course unit:
The aim of the course is to make students familiar with different types of hydraulic machines and equipment used in industry, in pumping stations, sewage treatment plants, in steam, nuclear and water power stations and which are used as elements in building machines, machine tools, as well as in robotics.
Learning outcomes and competences:
Students will be able to propose a design of hydraulic machines.
Prerequisites:
Basic knowledge of hydromechanics, especially of parts with respect to impeller pumps and reaction turbines.
Course contents:
The course familiarises students with basic facts relating to working principles of hydraulic machines and equipment used in all industrial fields. It deals with pumps, hydraulic motors, water turbines and fluid mechanisms (hydraulic and pneumatic elements, hydraulic transmissions and couplings).
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes:
Solution of tasks within the practicals. The exam testing the knowledge of the subject-matter.
Controlled participation in lessons:
Participation in practicals is compulsory. Absence may be compensated for via special tasks set by the teacher.
Type of course unit:
Lecture	13 × 2 hrs.	optionally
Exercise	13 × 2 hrs.	compulsory
