Zařízení na zkoušení termoregulačních vlastností termostatických hlavic / Test equipment for testing thermocontrol properties of thermostatic radiator valves

Štěpán, Tomáš January 2008 (has links)
This master's thesis is focused on the design of a device for testing the thermo-regulating properties of thermostatic heads. The engineering design, design of testing device has been composed according to the standard EN 215: Thermostatic radiator valves – Requirements and test methods. Based on these designs, sensors and regulation elements, which are suitable for testing, have been designed. Last part of the thesis deals with operating the device and measurement procedure.

Návrh destilační kolony / Design of distillation column

Matýs, Ondřej January 2008 (has links)
Distillation columns play a very important role in petrochemical industry. The requirements to their safety and lifetime are being constantly stepped up. Hence, they have to be designed very carefully and special attention is to be paid to strength analyses. The diploma thesis is focused on strength analysis of the distillation column carried out according to the ASME Code, Section VIII. Parts of the equipment and some nozzles were analyzed in operational and test conditions. One particular nozzle was analyzed more thoroughly by means of FEM, stress categories were considered. The work also includes worked out drawing documentation.

Měření teploty pneumatik za jízdy vozidla s využitím infračer. pyrometrů OS100 / Tyre Temper. Meauserement on Moving Vehicle with Use of Infrared Pyromether OS100

Morávek, David January 2008 (has links)
Bc. David Morávek Tyre temperature measurement on moving vehicle with of infrared pyrometer OS100 MT, IAE, 2008, page 70, picture 41 Problemacy of recording the temperature and tyre pressure on driven car is processed in this diploma work. Suitable measuring chain was set up. Censor holders for this type of measurement were designed and produced. Driving exams and tests are depicted in this work, too. We came to the conclusion that tyre temperature depends on lengthways and transverse acceleration of the car and also on it’s load.

Výpočty kontaktního tlaku z experimentalně určené tloušťky mazacího filmu / Calculation of contact pressure from experimentally evaluated lubricant film thickness

Kozel, Lubomír January 2009 (has links)
This diploma thesis is engaged in calculation of contact pressure from thickness of lubricating film using Finite Element Method (FEM). Within my diploma thesis were performed the calculations concerning to non-conformal surfaces with a view to elastohydrodynamic lubrication. The simulations were done for disk and ball contact, respectively with burnished finish and also with surface which contains small dent. Flow diagram was designed so that the creation of geometry, boundary conditions and results saving is controlled parametrically. With using parameters it is possible to repeat the calculation when the resolution, geometry, etc. will be changed.

Stanovení funkční závislosti koncentrace vzduchu ve vodě v závislosti na tlaku / Assesment of air concentration in water depending on pressure

Uttendorfský, Petr January 2009 (has links)
This thesis deals with dependence of heat transfer coefficient on rate of air concentration in the water. Main idea appears from gas dissolvability in water depending on pressure, Henry's law and Newton's law of cooling. There had been an experiment made to verify the hypothesis.

Parní turbina / Steam turbine

Vališ, Petr January 2010 (has links)
Goal of this dissertation is design of rotary reduction for entered input parameters that it is connected in parallel with reducing station. Further I´m looking into thermodynamic calculation of stage and chosen parts of turbine, making of project design of connection of rotary reduction to steam circulation. Dissertation is concluded by designed cross-section of turbine.

Tepelný a pevnostní výpočet výměníku / Heat and stress analysis exchanger

Jedlička, Rostislav January 2011 (has links)
The main goal of master’s thesis is a propsal of the heat exchanger. The heat exchanger is double way of water side with the integrated air-vapor mixture cooler. Another aims are heat computation, heat loss computation, solidity dimensioning and selection of a material for a major selection. The last task is about detection of a vapor pressure trought the tube bundle.

Modifikace adaptéru na kukuřici na sklopnou verzi / Hinged adapter of corn header

Řezníček, Milan January 2012 (has links)
The master’s thesis contains a plan of hinged adapter for cord header Cornpower 8-75 of the BISO Schrattenecker Company. The adapter is designed for threshing machines New Holland. The thesis includes a comparison of the mechanisms used by competitors. Further it contains design of the entirely different mechanism, its kinematics solution of the hydraulic circuit and calculating of the strength using FEM method, including calculation of contacts. The drawing documentation is done in Catia V5 and strength calculations in NX-Ideas and Marc 2010.

parní kotel na dřevo výkonu 50t/h / Stean boiler for wood burning 50t/h

Vitula, Michal January 2012 (has links)
Steam boiler for wood burning 50t/h In this diploma thesis I will deal design of the steam grate boiler 50t/h of burning clean wood. For the specified parameters make a stoichiometric calculations and calculate the enthalpy of the air and combustion. I shall calculate the heat balance, losses of boiler and thermal efficiency of the boiler. The following section make a design of the combustion chamber and its thermal calculation. After determining the dimensions of the combustion chamber further continue by calculating boiler moves and heating surfaces. Finally check the overall heat balance.
