Students learn more deeply with hydraulic and pneumatic components, their structures, functions, parameters, characteristics and use in hydraulic and pneumatic circuits. They know how to properly use these elements in hydraulic and pneumatic systems. In detail, students will learn the advanced control technology and servo technology in hydraulic and pneumatic actuators and mechanisms. They know the most important sources of constant pressure, and then use this knowledge to design systems with valve control. In the field of fluid power systems become familiar with key applications, ie, hydraulic and pneumatic machine drives and hydrostatic transmissions. They learn to deal with cases of start-ups and drive mechanisms, and calculate the thermal balance of fluid. They will learn the basics of reliability, operation and maintenance of fluid systems.


In the first part of the course Fluid systems and components in more detail, students learn about functions, structures, parameters, characteristics, and calculated using the fluid control elements, in particular hydraulic and pneumatic proportional valves and switchboards, control valves and servo-valves. In addition, sources familiar with the problems of pressure and flow of resources, capabilities and management (control pumps, battery drives, etc.).
In the section devoted to fluid systems become familiar with the properties of selected fluid systems such as systems with batteries, with proportional valves, energy saving systems, systems with two or more motors, systems, ensuring synchronous operation of hydraulic motors, systems for handling massive loads, etc.
Acquainted with the composition of hydraulic and pneumatic drives and hydrostatic transmissions. These systems will be able to design and carry out basic calculation parameters in steady state. They will be able to solve cases of acceleration and braking actuators, and solve the thermal balance of these drives. Meet the basics of reliability, operation and maintenance of fluid systems.
The exercises practiced brand of fluid elements, measuring the static characteristics of the fluid elements in laboratory to verify the properties and behavior of fluid systems, practicing the theory of fluid systems, analyze typical hydraulic and pneumatic circuits in steady state solves heats, brake fluid balance and thermal systems. Propose (projects) simpler types of fluid systems.
