Quantification of measurement accuracy of the pressure losses at evaluation of aluminium casting porosity
Velehradský, Petr ; Jelínek, Milan (referee) ; Pernikář, Jiří (advisor)
The diploma thesis deals with a matter of a leak testingo of the Schreiner devices in the company Kovolis Hedvikov a.s. The tested components are the heat exchangers made from alloy of aluminium used for automobiles. Due to the impact of porosity texture created during the components casting there is leaking. The analysis was accomplished to find out the most problematic parts of these components. Subsequently the testing and measuring were performed in order to classify the testing and detect its accuracy. The summary and suggested solutions of how to improve the accuracy of measuring of the aluminium components leaking are presented in the conclusion.
