Abstract

The thesis presents the analysis of the pneumatic tube system, one of the solutions in material handling. Contemporary solution components of pneumatic tube systems were presented and described, such as: blowers, diverters, send/receive stations, carriers, air brakes and system couplers. For the purpose of the article, a bypass air brake was built at the Laboratory of Techno-Climatic Research and Heavy Duty Machines of the Cracow University of Technology., which was then tested. The aim of the test was to determine the minor loss coefficient ζ, depending on the degree of the air brake valve override. The measurement results are given in the work.
