Vliv parametrů hadicového vedení na koncový tlak vody v řezacích systémech

Abstract

This thesis deals with the influence of tubing to the end pressure of water in high-pressure water cutting equipment, specifically the CCS Cobra. The first part deals with the liquid jets and it describes Cobra system. The second part deals with the theoretical calculations of frictional losses and losses due to elevation. The third part describes the measurement of pressure losses, including the measuring system and the evaluation of the measured results. Farther the results are compared with theoretically calculated values. As a byproduct of this thesis, instructions for the use of given measuring device were created for other applications at the Faculty of safety engineering.
