Nozzle separation valve design for rasterization electron microscope
Hoffman, Petr ; Navrátil, Václav (referee) ; Foltýnová, Dana (advisor)
The aim of the thesis is a design and subsequent construction of a vacuum separation valve for a scanning electron microscope. The introduction describes the functions of an isolating valve. The function of the scanning electron microscope is described in the overview of the current state of knowledge. The following chapters focus on conceptual designs of the valve, their descriptions, advantages and disadvantages. Based on the comparison, the most suitable solution was selected. A force analysis of the selected variant is also performed and described. The end of the thesis contains the whole structure design and processed drawing documentation.

Universal Inspection and Measuring Station
Brýdl, Adam ; Bradáč, František (referee) ; Knoflíček, Radek (advisor)
The task of this thesis is the design and construction of semi-automatic control and measuring station. The station is designed for testing the presence and measurement of the correct position of light guides and seals in the connector. Station contains a tool for testing the blinding of connectors. The design and construction of a semi-automatic control and measuring station is necessary using several types of sensors and sliding linear axes controlled by servo drives. The assignment of the thesis is solved in cooperation with the company Mechatronic Design & Solutions s.r.o. in Brno.

Experimental Stand for Determination of Turbocharger Lubricant Consumption
Kuhajdik, Matej ; Doman, Jozef (referee) ; Novotný, Pavel (advisor)
This work solves the problem of lubricant consumption in the turbocharger and air blow–by from the compressor part of the turbocharger into the bearing housing. The chosen problem is solved by the design of the test mechanism that will be used in the technical experiment. The experiment provides analysis options for the GT35 turbocharger rotor seal. Part of the work is a complete drawing documentation of the test equipment, installation procedure and instructions for operating the equipment.

Seal and sealing rollers
RYCHOVÁ, Denisa
The topic of this bachelor thesis are seals and cylinder seals. The theoretical part summarizes the basic information about seals and cylinder seals, a brief history of their creation and their use. Furthermore, the thesis deals with the idea of using seals and cylinder seals as aids for pre-school children. Last but not least, this thesis deals with the history and the current use of pictograms not only in everyday life but also its use as a kind of nonverbal communication. In the practical part cylinder seals and stamp seals to be made of ceramics and plaster, which can serve as aids not only for children of pre-school age.

Design of a hydrodynamic seal of an axial pump with an annular motor
Jančík, Kryštof ; Fialová, Simona (referee) ; Pochylý, František (advisor)
This diploma thesis deals with the design of a hydrodynamic seal of an axial pump with an annular motor, and it does so in three main thematic planes: research of current knowledge, simulation and experimental. The research section provides an overview of a broad problem of magnetic fluid seals (ferrohydrodynamic (FHD) seals), current developments in the field of simulation of internal flow in magnetic fluid and in the field of application of FHD technology in sealing liquids. It also covers a wider context of potential use for mechanical circulatory support systems that have had a significant impact on the proposed concept of a novel axial FHD seal. The remaining two thematic planes deal with his design and experimental testing.

Turbocharger seals
Holík, Petr ; Fiedler, Jan (referee) ; Škorpík, Jiří (advisor)
This master’s thesis deals with theme of turbocharger seals. The aims of a thesis are to compare a turbocharger seals used in PBS Turbo turbochargers and to describe a testing of a seals. Principle of turbocharging and types of turbocharger are described in fist part. Next point of the thesis is describing of a face seals and non-contacting seals. The main part of the thesis describes kinds and reasons of seals testing; also contains comparison between labyrinth seals and piston ring, comparison of seals of PBS Turbo’s turbochargers and assesses the impact of turbocharger angle on the tightness of the seal.
