DEVICE FOR IMPACT MEASUREMENT OF THE RADIAL PLAY OF A BRUSH SEAL AROUND A ROTOR

摘要

Device comprising a rotor (10) intended to be placed in a fluid (12) in circulation, a brush seal (2) surrounding the rotor (10), and in the immediate vicinity of the brush (4), a part segmented annulus (22) at least one segment (24a, 24b) of which is radially displaceable about the rotor (10) between: - a rest position in which a radially inner circumferential edge (26) of the segment (24a, 24b) is located at a radial distance d from the rotor (10), - a test position in which the radially inner edge (26) is located at a radial distance from the rotor (10), being less than d.
