Diagnostic system of paper machine
Škrobánek, Martin ; Jankových, Róbert (referee) ; Zuth, Daniel (advisor)
This master thesis deals with the technical diagnostics, focusing mainly on vibration diagnostics. This problematice is described in the first part of this work on a theoretical level. The next part describes the paper machine, diagnostic system and the measuring points are classified into databases. The practical part of this work consists of a proposal for the methodology of vibration diagnostics for a paper machine, the procedure for measuring and evaluating the measured values. Part of the work is also a practical example of the measurement of the central cylinder, on which the procedure is tested, and the compilation of new limit values.
Design of modification of the supporting structure of the press part of the paper machine
Zborník, Radek ; Zapletal, Zdeněk (referee) ; Pokorný, Přemysl (advisor)
The thesis deals with a description and a strength analysis of selected parts of a modified supporting structure of a press part of a paper machine. The construction is designed to simplify a replacement of felt belts during a service shutdown of the machine. The first part of the thesis is devoted to a brief description of the paper machine with a more detailed focus on the press part. The next part of the thesis includes a project of adjustment to the original design of the supporting structure. The last part deals with a strength control of construction nodes of the adjusted project. A strength calculation is further divided into a calculation using the finite element method and an analytical calculation. Results of both previous calculation methods are compared at the end of the thesis.
Guide roller scraper
Šmíd, David ; Omasta, Milan (referee) ; Frištenský, Miroslav (advisor)
This bachelor thesis deals with doctors, that play essential role in paper, food, or chemical industry. These devices have effect on economy and quality of manufacturing process. Analysis discusses usage of this device in paper making industry and it mainly focuses on individual structural nodes. From this analysis are created three possible designs, from which author of this paper selected one, that works on the principle of pressure caused by the weight of the doctor, which is further elaborated and made into drawing documentation. The work analyses the basic parameters for the doctor and checks possible critical points of the construction. The end summarizes results of these inspections and the final design of the construction. Solution can be only used on particular guide roll, which it was designed for.
