Abstract:
This thesis is concerned with the topic of Pumps with crew centrifugal impeller. Thanks to the benefits such as free passage and efficiency there are many practical applications of these products. Despite this fact there is only few manufacturers dealing with them what results in lack of research and available information in the area. In order to fill the gap, this thesis aims to propose hydraulic of screw centrifugal impeller to the specified parameters. The impeller with a single moving blade will be designed for pumping heavily polluted water and hardly pumpable liquids. Blade will be balanced together with the rotor, while the emphasis will be placed on the highest free passage of impeller. The theoretical part of the thesis summarizes literature on the subject, practical part deals with the calculations and adjustments pointing to a concrete proposal. Parameters of designed hydraulics were verified using stationary calculations using MRF model in FLUENT. As a results, two possible solutions are offered.

Abstract:
This master’s thesis deals with a new design of an oil pump for Tatra T158 transfer case. The new solution should replace earlier involute internal gear pump which is not able to provide sufficent lubrication. The main problem of the old design is a poor suction at low speeds of the vehicle. Gerotor type of the pump has been chosen. Its main advantages are a convenient specific flow rate and good volumetric efficency. In an analytic calculation of the pump gearing also important functional parameters have been checked, like a pressure angle, flow rate, flow irregularity, specific flow rate, specific slipping. A design with and without axial clearance compensation is introduced. Measurements on a test rig confirmed good suction ability even in low revs. Generated flow rate and pressure are improved. That is a good prerequisite for faster assembly of transfer case with no testing of each oil pump. The tests have not revealed any unexpected wear of parts of the pump so far. It is supposed an application of the new gerotor design in a serial production of T158 truck and other types in the future.

Abstract:
The wastewater treatment process is one of the most important processes which contributes to the protection of the environment. This process can also potentially recover necessary and scarce raw materials, such as phosphorus. Research of the wastewater treatment technology is an increasingly relevant topic and more innovative knowledge should be gradually implemented into existing plants. However, the implementation of such technology involves increased investment and often operating costs. This is, why there is a growing interest in improving the energy intensity and hydraulic efficiency of the installed wastewater plant machinery. The optimization of operating parameters in such machinery can also bring significant savings, which can be potentially re-invested into other technologies. This work deals with the issue of proper evaluation of installed machinery for the selection of operating parameters and assessment of their significance. As the challenge, wastewater treatment technology is very sensitive towards the combination of technological equipment and incorrect operational parameters can lead to erroneous evaluation of the efficiency of individual equipment or inappropriate engineering proposals. To eliminate these risks, an analytical procedure for the selection and evaluation of parameters is proposed in this work. This procedure is demonstrated on six types of equipment. To verify the conclusions of the proposed procedure, a model design of the equipment was performed, in which the influence of individual parameters was concisely assessed. By using the data, the proposed procedure could be validated more specifically. In this work, the necessary data for the design was obtained by experimental research and extensive testing. The results confirm the practical applicability of the proposed procedure.

Abstract:
The proposed work is dealing with control design of pump-tank system as part of broader water-supply network with using of mechatronic approach. The main goal of this work is design of control for regulation of flow, pressure and water level in tank in water-supply network of Vsetin city. This water-supply network consists of various components, such as pumps, pipes, valves, tanks etc. For the purpose of the control design is necessary to create a model of pipe network. The solution of hydraulic analysis is obtained by using the gradient method, which was implemented into the software solution named ADAM. The results of hydraulic analysis are compared with measured values of flow and pressure and difference of these values has to be minimalized by proposed calibration and verification process. The calibration and verification process was implemented in software ADAM. The essence of design control is formulating control problem as optimization problem. Therefore the output of higher control layer is set of procedural rules, which determines for example speed of pumps in time etc. Results were verified by using for this purpose developed computational server (ADAM Server).

Abstract:
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.

This master’s thesis pertains to heating practices of low-energy houses using a heat pump (example 1) and low-temperature condensing boiler (example 2). The first part of the work contains calculations of suggested building’s heat efficiency and of under-floor heating. The second part of the work includes estimates of seasonal heating factors for construction with a heat pump. Based on the comparison: both of these heating systems are recommended; the capacity of the warm water container is established; and safety elements are chosen. Furthermore, a system of regulation for warm water heating is determined, and a curve of equithermal regulation for heating is calculated. Both of the recommended heating possibilities include calculations of costs of supplies and manufacturing, as well as blueprints for construction.

The aim of this thesis is to design the heating system for the house, including the design and calculating the required quantity of heat for hot water. The specified heat sources are the heat pump air to water and solid fuel boiler. The task was to design the heating system to the fastest possible return on investment. The initial investment in a heat pump is high so it is necessary to design the heating system as efficiently as possible. The thesis contains a complete project of calculating heat loss of the building, the design of heating surfaces and their heat-technical calculation. There is included the design of the pipe system, the calculation of pressure loss and its regulation. The thesis also includes design of safety equipment, temperature regulation and drawings. On the basis of calculated data was processed economic assessment, which determines the return on investment to the heat pump. Compared to the gas condensing boiler the return on investment will ideally be after five years.
