Packing is equipped between subring, rotor is compacted in track ring by track ring end by supported flange, and supported flange passes through multiple
Fastening bolt is connect with track ring.
Further, the rotor is annulus cylindricality, and the outer diameter of two ends of rotor is less than the outer diameter at intermediate position,
Intermediate outer wall section is at convex.
Further, the inner bottom surface in the track ring positioned at rotor side is recess, the in-profile shape of recess with
The outer contoured shape of rotor contact position is consistent, and the face exterior contour and track ring inner bottom surface that sealing element is contacted with track ring are recessed
Sunken in-profile shape matches, and the face exterior contour that sealing element is contacted with rotor and rotor are located at the outer of track ring one end
Contouring shape matches.
Further, packing is corresponded between the rotor and track ring and is equipped with packing pressure ring, corresponds to packing pressure on supported flange
Multiple hold-down bolts are equipped with, packing is pressed between rotor and track ring by packing pressure ring by each hold-down bolt.
Further, the packing is oiliness packing.
Further, the sealing element is heavy wall hard oil nylon seal members.
The beneficial effects of the utility model are: structure is simple, no infiltration runs smoothly, so that sewage without excessive, makes shallow-layer
Airfloat equipment is without later period worry, and appearance is cleaner and tidier.
