Měření silového působení kapalinového paprsku při používání vysokotlakých zařízení

Abstract

This bachelor thesis deals with action of forces of liquid jet and with transferring results to CCS Cobra device. In the first part this thesis gives general information about liquid jets used in industry field and it describes specific CCS Cobra device and its usage. The second part deals with abrasives used by fire-fighters in CCS Cobra device. The third part is focused on theoretical calculations of liquid jet force impact, recalculating to CCS Cobra device and on comparison of calculated outputs with results, which were measured on jets in laboratory. In the last part measuring of back impact on CCS Cobra device and comparison of these results with theoretically calculated outputs is described. The conclusions of this thesis can be used in any working place using high-pressure water jet.
