Měření těsnosti pneumatických rozváděčů

Abstract

The bachelor thesis deals with the tightness of directional valves with different types of seals. The introductory part describes the types of structural directional valves, the division according to the types of control and the number of ports. Furthermore, selected directional valves and the problem of individual types of seals are both described. The next part of the thesis is an introduction to the issue of measuring directional valves, especially the measurement of volume losses (tightness). Experimental measurements in the laboratory of pneumatics, the VŠB-TUO, a description of this measurement, the equipment used and the evaluation of the experiment are proposed.
