Positive displacement pump design
Klapka, Petr ; Šperka, Oldřich (referee) ; Klas, Roman (advisor)
This thesis gives an overview of the structure of hydrostatic pumps. First, there is shown the integration of the hydrostatic pumps between other hydraulic machines and then there are described the fundamental relationships and characteristics. The main objective of this work is to make a basic list of species distribution and the classical hydrostatic pumps. For each type, while mentioning his principle, his description of the main members is also highlighted some of their advantages and disadvantages.
Elimination of defects in the gears manufacturing
Petříček, Vít ; Jaroš, Aleš (referee) ; Fiala, Zdeněk (advisor)
The aim of the diploma thesis was to analyze qualitative outages in the production of gears for a gear pump and to minimize them. The largest amount of outages was caused by the burning of the surface during face grinding. After analyzing the current state of production there were created some suggestions to avoid this issue. Also there was found some space to speed up the whole process. Suggestions to eliminate burning have been tested with minimal impact on production. The reduction of outages for burned surface was achieved and also the cycle time was shortened. Those suggestions will be implemented in serial production.
The tooth pump in the turbine regime
Tyburec, Adam ; Dobšáková, Lenka (referee) ; Haluza, Miloslav (advisor)
The objective of this diploma study is to develop and secure production of gear turbine with very low specific speed in comparison with conventional turbines. The first part of the work deals with already performed research of similar hydrostatic turbines. It is followed by construction design, including complete drawing documentation. The production of the prototype is secured by an external company. Finally, an experimental measurement of the characteristics of the designed turbine is performed in the laboratories of Fluid Engineering.
Methodological guide and digitization of gear pump
Ševčík, Ondřej ; Nevrlý, Josef (referee) ; Nečas, David (advisor)
The aim of this bachelor thesis is to provide a methodological quide of U10 type gear pump. In the first part of the thesis, analysis of individual pump components including its main parameters is presented. The next part is focused on the identification of the defect suggesting the instructions for the reparation. All the operations such as dismantling, inspection, reparation, and assembly are described in a detail in a form of the technological processes. After the reparation, an operating test was conducted to verify the functionality of the pump. In addition, all the components of the pump were digitized by using SolidWorks CAD system. The last chapter provides FEM analysis of the cogwheels contact. For this purpose, computational system ANSYS Workbench was used.
Micro power plants for the use of residual gradients and flow
Komorová, Magdaléna ; Dráb, Aleš (referee) ; Žoužela, Michal (advisor)
The aim of the bachelor thesis is to bring information about where hydropower is going in the future in accordance to using residual gradients and flow. Also, bachelor thesis is looking into different types of turbines which can be used for residual gradients and flow, then how government is helping with funding of new and existing hydropower plants. The last part of thesis is analyzing new location for picohydropower plant and bringing three possible designs.
