Determination of the working range and efficiency of the water hammer pump
Růžička, Jakub ; Haluza,, Miloslav (referee) ; Špano, Miroslav (advisor)
This thesis focuses on setting the range and efficiency of a water ram pump through experimental measurements in a laboratory. The measurements were carried out on three different constructions of water ram pump, each of the designed and assembled by the author of this thesis himself, to find out whether the weight on the pulsating valve has an influence on the water ram pump efficiency. Further on this thesis aims at the comparison of up to now methods of water transport arrangement used at a summer camp and the usage of the water ram pump and its advantages. The principal of water ram pump originates in hydraulic impact that is being precisely described in a great detail as well. On of the chapters even includes the placement manual for the water ram pump and its overall assembly and connexion. Because the presence of floating debris is inevitable, this thesis also deals with the possibility to solve the incoming water impurities by adding an inflow gating to prevent such problem. This inflow gating has only been designed in a Flow 3D programme to introduce the idea and functions.
Water supply of scout camp by hydraulic ram
Růžička, Jakub ; Duchan, David (referee) ; Špano, Miroslav (advisor)
This work is dealing with water supply of a scout camp from Trusovický potok. The water is pumped with a ram pump to the water tank. The construction of the ram pump is simplified and it is collected from commonly available fittings and fixtures. The water from the tank is distributed by pipe network gravitationaly. Operating charakteristics of the hydraulic ram pump were measured in the laboratory.
Measurement of dynamic characteristic of check valves
Novák, Jan ; Himr, Daniel (referee) ; Habán, Vladimír (advisor)
Master thesis presents overview of existing types of check valves, their features, uses and issue called "cracking". Experimental part of this thesis focuses on the lift and swing check valves. Results of the measurement are evaluated from non-stationary flow point of view by developing and analyzing static and dynamic characteristics. This thesis takes into account losses and dynamic effects as main viewpoints. Two methods for measuring non-stationary velocities are used. Direct method called Gibson and indirect method laser doppler anemometry. Goal of the master thesis is to increase understanding of the check valves and their applicability.
Heating of the guesthouse
Diatel, Jakub ; Topič, Jan (referee) ; Počinková, Marcela (advisor)
The theoretical part of this thesis is based on ideal design of solar systems and determine physical properties of antifreezing mix based on glycol in different concentration by Swiss mathematical model. In practical part is solved heating of the guesthouse by pellets. Heating of the hot domestic water was designed by solar collectors. Forced ventilation was designed with heat recovery.
Study of plunger pump with inverse ball screw and submersed motor
Švestka, Jiří ; Himr, Daniel (referee) ; Pochylý, František (advisor)
This thesis is focused on study of piston pump with ball screw and submersed motor. Theoretic part is about study using pump and ball screw. Equations for description of pump, motor and ball screw are in computation part. And in last part is construction of pump and valve. Valve is computed in CFD.
