In my thesis, I discuss the role of the distributor valve unit, which is one of the most important elements of the rail braking systems. This device is responsible for the generation and transmission of appropriate braking forces and the handling of additional air reservoirs. The leak test is essential for product validation, since by such a device it may have a powerful effect on the intended operation.
Given that I made this thesis in an industrial environment, firstly I would like to briefly introduce the host company and the objectives.
As a first step in the dissertation, I presented the history, the basic principles and the operational concepts of the rail braking systems following literature research. I located the steering valve within this system and detailed the role and functions of the various modules.
My next task was to explore differences and similarities between the old and the new generation steering valves, as they could greatly alter and ease workflow. Additionally, it was also important to explore the types of leak tests and the possibilities offered by the company, so that I can use the appropriate and practical concept.
After all this, I continued my thesis by explaining the solution. I wrote about the prepared pneumatic plan and the test program, and finally, I got the proper conclusion.
