Proactive system maintenance machines in engineering practice
Križanová, Bronislava ; Řezníčková, Hana (referee) ; Hammer, Miloš (advisor)
This bachelor thesis deals with the topic of proactive maintenance of machine tools. Different systems of maintenance, most widespread methods of diagnostics are described in the thesis and then there is selection of appropriate method of technical diagnostic state for machine tools in company. Tribological diagnostic is developing method and apposite for any kind of machines with lubricating system or machining emulsion. In practical part, it is focused on the analysis of installed maintenance system in the company, overview of actual analysis and measuring instruments of tribological diagnostic for machine tool. Prior to the end the process in field of proactive solving of systems of maintenance has been recommended for SMC Industrial Automation CZ LLC Vyškov.

Information system in the maintenance
Lang, Karel ; Hammer, Miloš (referee) ; Řezníčková, Hana (advisor)
The aim of this bachelor thesis is to investigate the possibilities of usage various information systems in the management of company maintenance and to apply this knowledge to the current management maintenance system in Megatech Industries Hlinsko. The first part of the problem was solved by mapping the current market and comparing the offers of the individual information system maintenance providers, the second one was carried out in cooperation with the maintenance manager of Megatech Industries Hlinsko using the software solution Palstat CAQ. The findings of this work show that enterprise maintenance management can be performed in many ways, and almost any maintenance system can be supported by some kind of software support. Meanwhile, it has been proven, on the example of Megatech Industries Hlinsko, that no way of managing maintenance is perfect, and an independent observer can always find reserves for improvement.

Safety of technological systems
Jiříček, Petr ; Pavlík, Josef (referee) ; Hammer, Miloš (advisor)
The work deals with the safety of technological systems and can be divided into two main thematic units. The attention in the first theoretic unit is paid to aspects that affect the safety of technological systems during their technical life. It describes, together with elementary norms and acts solving the products safety, the most important principles for creating and analysing the safety. It clarifies the origin of company’s risk management, part of its quality management, mentions the faults in which products can be found and also describes the failures which have the biggest effect on these faults and of course on the safety too. Attention is further paid to the reliability analysis, as the tool that helps to create the products safety in the pre-manufacturing phase and also to technical diagnostic, as the tool to keep the safety in after-manufacturing phase. The second practical unit arithmetically analyses the safety of two high-voltage transformers. For that it was used the database of real operation numerical values that were gained during diagnostic investigations on these transformers. In addition it describes mentioned diagnostics methods and gives the new procedure for analyse of transformers’ safety by criteria matrix and weighted sum approach. The main contribution of the work can be considered the checkout and the evaluation of this procedure for use in elaboration of high-voltage transformers diagnostic values for analyzing their safety.

Principles of maintenance of the TPM method
Zahradníček, Lukáš ; Hammer, Miloš (referee) ; Řezníčková, Hana (advisor)
This master thesis concerns modern method of TPM used in the production companies for maintenance of machinery. In the theoretical part, general maintenance is first described, as well as the TPM method. There is also described the technical diagnostics, which was emphasized in the practical part in terms of the use of vibrodiagnostics in predictive maintenance. In the practical part there is presented the proposal for introduction of the TPM method at the SMC Industrial Automation s.r.o. in Vyškov.

Noise Generator Diagnostics
Plucková, Iveta ; Nahodil, Petr (referee) ; Hammer, Miloš (advisor)
The bachelor thesis deals with noise diagnostics of the generator. The practical part of the thesis is realized in the Dukovany Nuclear Power Plant. The first part of the thesis, noise is generally discussed. The quantities and their measurements are described, quite generally, also for the given company. According to specific conditions in the Dukovany Nuclear Power Plant, there is a distribution of noise measurements, which is carried out by an external company. The work gives a concrete example of this measurement. At the end of the work, the practical measurements of noise were done for selected generators, which were realized by an author for the purposes of this bachelor thesis. The experiment is evaluated.
