MEASURING DEVICE OF CONTACT PRESSURE OF ELASTIC SEALS

摘要

FIELD: measurement equipment.SUBSTANCE: measuring device of contact pressure of elastic seals includes a housing with operating pressures supply channels to the seal zone, and a stock that is movable in axial direction and has a groove for installation of the tested seal. Test pressure supply channel is made in the form of a capillary passing with a gap in the housing opening till it contacts the working surface of elastic seal; the above capillary is securely fixed in a flange forming together with the housing a test gas collecting chamber and restricting the capillary outlet flush with the housing surface.EFFECT: improving measurement accuracy of contact pressure of elastic seals.1 dwg
