Proposal of Methodology for Reliability of Operation and Optimization of Rotary Machines Maintenance
Řezníčková, Hana ; Helebrant, František (referee) ; Pačaiová, Hana (referee) ; Hammer, Miloš (advisor)
The presented doctoral thesis is focused on solving reliability of operation and optimization of maintenance of rotary machines. In the theoretical part, the RCM method is analyzed in detail including several available modifications of this method. Furthermore, the most commonly used methods of technical diagnostics are presented. The practical part is focused on the design of a new methodology based on the RCM method.
Total Productive Maintenance (TPM) in Business Practice
Morcinková, Lenka ; Nahodil, Petr (referee) ; Hammer, Miloš (advisor)
Master’s thesis is concerned with maintenance management in manufacturing companies focusing on TPM. The first part of the thesis deals with the topic theoretically and proposes possible solution in company Siemens Electric Machines s.r.o. based on system analysis. The practical part then describes the current state of maintenance management and recommend various measures to improve autonomous, scheduled and reactive maintenance in this company.
Using tribodiagnostics in predictive maintenance in company practice
Trost, Daniel ; Nahodil, Petr (referee) ; Hammer, Miloš (advisor)
The thesis deals with the use of tribodiagnostics in predictive maintenance in corporate practice. It is generally dealt with maintenance, then tribodiagnostics in the company Škoda Auto a.s. Used offline and online diagnostic tools are described. Emphasis is placed on verifying the functionality of the newly purchased online filter unit. The experimental part is focused on detailed analysis of the above, including comparison of measurement results offline and online diagnostics. There is also an economic evaluation of savings obtained by operation the online filter unit. In conclusion, the tribodiagnostics recommendations are given for Škoda Auto a.s.
Multiparametric generator diagnostics
Buchtová, Blanka ; Nahodil, Petr (referee) ; Hammer, Miloš (advisor)
The thesis is focused on multiparametric diagnostic of generators at the Dukovany nuclear power plant. One generator was chosen for the thesis and it was examined especially from the practical point of view. The thesis describes current state of the issue with focus on noise diagnostics, vibrodiagnostics and electrodiagnostics. The emphasis is on the system approach of the solution. In the practical part an experiment is designed, described and evaluated. Attention is paid to the conclusions of the performed vibrodiagnostics and noise diagnostics. Data sets are evaluated separately and the relationship between the two diagnostic methods is analyzed. Furthermore, the data set from electrodiagnostics is evaluated and dependencies of electrical diagnostic quantities on other quantities are described. Trends in electrical diagnostic quantities are also monitored. Conclusions and recommendations are formulated at the end of the thesis. It is stated that using multiparametric diagnostics to assess the status of generators in power plants is still in its beginning and that the conclusions of the submitted thesis will contribute to the developmnet in this area.
System of On-/Offline temperature measurement based on Lab View
Stejskal, David ; Hammer, Miloš (referee) ; Prostredník, Daniel (advisor)
The objective of this thesis was to create a LabVIEW-based program for temperature measurement using a personal computer. The program allows reading and post processing of digital signal from a measuring device. This device consists of a sensor type PT100, a measuring transducer and an analog-to-digital converter with USB output. The theoretical part of the thesis deals with resistance temperature sensors, signal analysis and methods for signal processing. The practical part is conceived as a guide to the created program. This part introduces vital sub-elements of the program and describes their principle, practical use and also the operating instructions. As required by thesis assignment, practical part includes verification of the measuring device, which was performed in laboratory of Czech Metrology Institute in Brno.
Online vibration diagnostics of the DATRON milling machine spindle
Kříž, Petr ; Hammer, Miloš (referee) ; Jankových, Róbert (advisor)
This master’s thesis deals with online vibration diagnostics of the milling machine spindle. It is aimed at the implementation of the complex online vibration diagnostics system to chosen milling machine, the suggestion of the vibration measurement system and the suggestion of the evaluation of changes of the technical condition of this milling machine spindle. The description of the vibration diagnostics, the description of the milling machine spindle construction and function and the suggestions for the practical application of vibration diagnostics are also parts of this thesis.
8D report as a tool for improving the quality of production
Machová, Lenka ; Opočenská, Hana (referee) ; Hammer, Miloš (advisor)
The Bachelor's thesis is focused on the quality as a means of effective production. Furthermore, it demonstrates individual methods, which are relevant in quality improvement . The procedures and a method 8D that were chosen are described in detail. Such as beneficial funds for quality improvement. The method 8D is considered the most effective mode. In order to achieve these objectives is provided minutely delineation of individual steps of the strategy. The main objective of this work is an analysis of a specific example for business practice. Moreover, it elucidates solutions of the 8D complaint report usage.
Using the TPM in machine maintenance
Velebová, Petra ; Opočenská, Hana (referee) ; Hammer, Miloš (advisor)
Bachelor´s thesis deals with the using of TPM (Total Productive Maintenance) in machine maintenance. The theoretical part describes the maintenance, its development and the methods used with the TPM. The practical part describes actual level of the TPM for machine maintenance in Bosch Diesel s.r.o. The aim of the bachelor´s thesis is analysis the using of TPM in machine maintenance, furthermore, to propose an extension of the existing TPM standard to effective training course in all positions. Also design a control mechanism for checking knowledge at each position. The results are analysed and evaluated in bachelor´s thesis.
On-line diagnostic monitoring systems for vibration of machines
Cirhanová, Iva ; Prostredník, Daniel (referee) ; Hammer, Miloš (advisor)
The bachelor thesis deals with diagnostic monitoring systems of machine vibration. First of all, a technical diagnosis with a focus on diagnostic methods, means and diagnostic systems is generally described. Special attention is paid to vibrodiagnostics and termodi-agnostics. In the next part of the thesis there are on-line diagnostic monitoring systems, their parameters and their use in technical practice. Emphasis is placed on systems from SKF, ADASH and ifm electronic. The systems are compared and the economic aspect is briefly outlined. In the bachelor thesis is also evaluated.
Monitoring differential pressure of filters
Vacek, Jiří ; Kratochvíl, Petr (referee) ; Hammer, Miloš (advisor)
In this bachelor thesis is at first dealt with pressure, pressure, manometers, technical diagnostics and monitoring. In next part is analysis of methods of particle filters on basis of published academical papers.
