Course objectives

The aim of the course is to familiarise students with the principles of hydraulic systems, hydraulic components (such as pumps, valves, actuators) and their control aspects.

Course content
Lectures

1. Basic knowledge 2. Batteries, filters, power supplies, hydraulic oils 3. Transmissions, shut-off valves, flow diverters, proportional valves 4. pumps, axial piston energy converters, hydraulic motors 5. Power cylinders, pressure regulators 6. construction and operation of servo valves, principles of their selection, their application 7. Principles and laws of design and sizing of hydraulic systems 8. Construction and operation of modern servo drives 9. Hydraulic measurements: direct acting pressure relief valves 10 Hydraulic measurements: recording characteristics of a pilot operated pressure relief valve 11. testing of hydraulic motor, throttle, gearboxes and self-regulating pump

Labs

Learn how to assemble hydraulic couplings, learn how basic couplings work, design task.

Acquired competences
Knowledge

Students will gain the knowledge of standard hydraulic systems

Skills

The students will have the skills to design and create basic hydraulic systems.

Attitude

Students will eagerly search for suloutions in hydraulic system designs.

Autonomy and responsibilities

They will be capable of design basic hydraulic powersystem alone.

Requirements, evaluation and grading
Mid-term study requirements

Written and oral test on theory 40 points (minimum 20 points) and practical tasks 45 points + planning task 15 points.

Generative AI usage

1st position: Use of GAI tools is not permitted for solving assignments. This means GAI tools cannot be used to complete formative or summative assessments, and using GAI constitutes academic misconduct. The use of AI tools for spelling and grammar checking does not fall under this prohibition.

Study aids, laboratory background

Hydraulic workstations for practical tasks, tests and measurements. PC workstations for designing simulation tasks.
