Retrofit IP-LP Section Steam Turbine 300MW
Pavlik, Richard ; Fichtl, Richard (referee) ; Fichtl, Richard (referee) ; Fiedler, Jan (advisor)
The aim of this master’s thesis is a retrofit of condensing three case steam turbine K300-170 with reheating. In the first part, the heat balance of the system is calculated for given parameters. The design of the flow section is focused on the combined intermediate pressure and low pressure turbine section and it consists of defining rotor and blading characteristics. In the stress control, the stress of the designed blading is checked and for the conclusion the shaft seal losses and their effect on the overall output power of the turbine are estimated. The drawing of axial section of combined intermediate pressure and low pressure turbine section is also included in the thesis.

Lift positional table
Solovský, Jakub ; Kašpárek, Jaroslav (referee) ; Pokorný, Přemysl (advisor)
This bachelor thesis is focused on functional strength calculation of scissor lift mechanism, which serves for transporting loads of a weight 500 kg situated on a pallet. Required lift height is from the first position 0,75 m to the second 2,5 m above the ground. There are mentioned engineering design, calculation of roller conveyor drive, dimension of lifting mechanism and concept of linear hydraulic motor in particular parts of the thesis. Other part of this thesis is drawing documentation.

Design of lift positional table
Vajmar, Jan ; Malášek, Jiří (referee) ; Pokorný, Přemysl (advisor)
This bachelor’s thesis describes the design of a lift positional table for loads of a weight 750 kg and stroke positional table 1000 mm. At the beginning of the work is a brief analysis of the problems of lift positional tables and choice of design solutions. In addition to addressing the drive tray pallet on the table using the roller track. It addresses the dimensions of the scissor mechanism, its load, stress control and design of the actuator stroke. The work also includes drawings.
