Pump station design optimization
Kunovský, Lukáš ; Klas, Roman (referee) ; Štigler, Jaroslav (advisor)
This diploma thesis summarizes the necessary knowledge for the design of the pump station. It focuses on the choice of suitable pumps and control valves. It also provides information on mathematical optimization methods. By combining these two disciplines a program was created that selects the most suitable combination of pumps and valves for the assigned requirements. These can vary over time. The goal of optimization is to minimize initial and operating costs. The phenomena considered are: time-varying flow and head height, serial and parallel co-operation of pumps, throttling control, a change of characteristics for variable speed and temperature, suction height control, maximum motor output, loss in connection piping.

Experimental stand for mechanical heart valves
Ermis, Martin ; Kůrečka, Jan (referee) ; Šedivý, Dominik (advisor)
The thesis focuses on experimental stand for mechanical heart valves. It consists of brief research about cardiovascular system and artificial heart valves. Another part of the thesis is report about measurement made on the stand. This is followed by analysis of other experimental stands in the world and suggestions for improvement of current stand in the laboratory of Victor Kaplan Department of Fluid Engineering.

Seting of Working Point of co-Operated Centrifugal Pumps
Sůkal, Jaroslav ; Koutný, Luděk (referee) ; Štigler, Jaroslav (advisor)
The aim of my diploma thesis is to create a computer program that will help planners to design pipe systems. The program enables to find the parameters of a pumping unit (such as flow, head, power, efficiency, dissipation etc.) in a parallel pipe system which even has two tanks with dissimilar height. Moreover, the program is able to “calculate” the parameters of pumps that have maximum efficiency so that the planner could easily compare the data and determine whether the pump is working near the optimal point. The introduction includes a short overview of issues connected with pumping equipment. The next part deals with a description of software solutions of individual problems. The thesis concludes with a manual of the designed computer program.

Sludge Pumping on WWTP
Fadrný, Tomáš ; Medek, Jaroslav (referee) ; Boráň, Jaroslav (advisor)
This diploma thesis deals with the best solution design for a sludge fitting, especially focusing on the right choice of pumps for the waste water treatment plant in Prostějov. The pumps were selected for a circulation pipeline, which heats up the sludge. Several measurements were carried out in order to determine the statistical evaluation of the properties of the pumped medium. The figures gained were used to calculate pressure losses.The diploma thesis is divided into two parts. The first part provides a theoretical analysis of the problem and the second part presents the results and subsequently the reasoning for the new selection of pumps in order to change the WWTP technology from the mesophilic to the thermophilic sludge digestion. The test records describing the testing of the individual samples of the pumped sludge are attached.

Design of chiller for specific application
Gaverník, Michal ; Kohoutek, Josef (referee) ; Jegla, Zdeněk (advisor)
This diploma thesis deals with design of chiller for specific aplication – The City Theatre in Brno. The solving equipment of cooling appliance includes complete design of heat exchanger, battery cold and dimensioning of pipeline system used for various media. One part of design is also choice of individual coolant pumps, which guarantee necessary cirkulation of cooling medium in a certain pipeline routes. Selected battery cold in this administration reduced the size of the necessary cooling resources, therefore the cost of implementation. Everything is processed in calculating software. The resulting proposal is also drafted in the design program and will serve as one of the bases for subsequent implementation.

Pump design
Šmíd, Pavel ; Šperka, Oldřich (referee) ; Klas, Roman (advisor)
The aim of this labour is to analyze the structural design of pumps used in the present time. First, we focus on the distribution of pumps by type of energy conversion, and there are hydrostatic and hydrodynamic. Will further comparison of these types, and enter the region of their optimal application under specific speed. This labour will focus only on the hydrostatic pumps when we will do an analysis of design performance of the individual pumps and we'll give the advantages and disadvantages of the specific pumps. We shouldn´t forget the basic technical parameters and individual areas of practical use these given types. At the end of the labour will be processed the basic equations and the ideal characteristics of pumps.

Energy consumption analysis of water utilities
Bábíček, Michal ; Raclavský,, Jaroslav (referee) ; Ručka, Jan (advisor)
In the first part was an analysis of possible cost-saving measures to reduce energy consumption in the countries of Central and Eastern Europe and the former Soviet Union. Part of the work analyzing energy savings for water treatment plant Bzenecis divided into three parts. Part one deals with a brief description of the individual technological units. In the second part of the individual technological units analyzed in terms of savings already realized by the operator and also in terms of savings that operators shall submit for consideration and possible implementation. The lastthird part summarizes the findings in the second part of the analysis and alsooutlines possible new solutions that are applicable to all objects of the operator.
