Noise and vibrations of roots blowers
Smrček, Martin ; Hájek, Petr (referee) ; Švancara, Pavel (advisor)
This thesis is concerned with the spread of noise in the housing sets blowers, blower vibration, due to the shape of the geometry of the individual parts of the blower and the design of a suitable discharge muffler in order to achieve the highest possible attenuation. Analysis blower and silencer discharge was conducted using the finite element simulation ANSYS 15.0

Reversing cross for flexo printing machine
Falta, Jan ; Mazal, Pavel (referee) ; Brandejs, Jan (advisor)
The aim of this work is to develop a new concept of the reversing cross for flexo printing machine SomaFlex Optima. Work includes a description of the machine, the basic description of the principle of flexography. There is explained the principle of turning the material, the current method of supplying air to the air cushion and the difference between the blower and compressor as an air source for the air cushion. Conceptual solution includes two variants, namely vertical and horizontal position of turning bars. For each alternative are described its advantages and disadvantages.

Optimization of electric power consumption of gasification wood boiler
Fejta, Vojtěch ; Šnajdárek, Ladislav (referee) ; Brázdil, Marian (advisor)
This thesis deals with the optimization of the electrical supply of a domestic boiler. The objectives were description of the legislative requirements for domestic boilers, comparison of their electrical input, description of the design of the main electrical components of domestic boilers, comparison of their parameters, analysis and design of constructional modifications leading to reduction of the electrical input of the selected domestic boiler and implementation of the proposed measures. The thesis is divided into four main chapters, the first two are devoted to boilers and their electrical components. In the third chapter, a new boiler blower impeller and other modifications are designed to reduce the power consumption. The last fourth chapter deals with the design, assembly and testing of these modifications.
