Pump design
Hlaváček, David ; Koutný, Luděk (referee) ; Klas, Roman (advisor)
The bachelor thesis contains basic information about hydrostatic pumps. In the first chapter, there is a basic dividing of hydraulic machines, it is followed by a brief charakteristic of the hydrostatic and hydrodynamic machines with their advantages and disadvantages. The main part is devoted to the hydrostatic pumps. At the beginning, there is dividing pumps, it is suplemented by principle operation of the individual types with transport parameteres, relations for calculating the geometric volume and with their advantages and disadvantages. At the end there are some basic formulas for calculating the hydrostatic pumps with their theoretical and real characteristics.

Assessment of stiffness, damping and added mass in thin liquid layer in sealing gap
Kohut, Vojtěch ; Pochylý, František (referee) ; Habán, Vladimír (advisor)
The main purpose of this master’s thesis is to propose the methodology suitable for experimental evaluation of additional mass, stiffness and damping by which a liquid layer in the sealing gap affects the rotor. Sealing gaps are important structural elements of hydrodynamic machines. An appropriate design of a sealing gap including the additional effects determination is an inevitable part of the machine overall dynamic design. The thesis also provides a literature search in the field of rotor dynamics and additional effects of a liquid. The designed experiment aiming to determine additional effects of the liquid is based on rotor dynamics evaluation by means of the radial forces measurement. The experiment results were used to determine dynamic properties of dry and wet rotor of the testing device.
