Model utility content
The purpose of this utility model is to provide a kind of magnetic mechanical sealing device, by being provided with dust-proof cushion, can play dust-proof effect, ensures that the end-surface friction pair of magnetic seal cleans, the good and long service life of sealing effect.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of magnetic mechanical sealing device, be arranged on line shaft, include and be nested with rotating ring and stationary ring on line shaft, the Sealing sealed with line shaft is installed in the seal groove of rotating ring, outside stationary ring, cover has stationary seat, between stationary ring and stationary seat, Sealing is installed, in the seal groove of stationary seat perisporium, Sealing is installed, the compressing tablet blocking stationary ring is installed in the inner stopper of stationary seat; It is characterized in that, described stationary ring has counter sink towards the end face of rotating ring one end, is provided with magnet in the aperture of counter sink; Described rotating ring is magnetic material, and because magnet is to the suction of rotating ring, rotating ring and stationary ring are close to; The dust-proof cushion be enclosed within line shaft is installed between described compressing tablet and stationary ring.
Further have, described dust-proof cushion cover has center hole and is enclosed within line shaft, and dust-proof cushion centrally hole is outwards provided with flange.
Further have, described stationary seat outer edge is outward extended with step.
Further have, described step has mounting hole.
Further have, described Sealing is O shape circle.
Compared with prior art, the beneficial effects of the utility model
The utility model designs for unit loading type, the magnet of stationary ring and rotating ring attracting can together with install, very convenient.Outside stationary ring, be provided with dust-proof cushion, and dust-proof cushion is enclosed within line shaft, dust-proof cushion can play obstruct dust or impurity enters on rotating ring and stationary ring seal face, the sealing effect of rotating ring and stationary ring is stablized, such double seal, overall sealing effect is better, can increase the service life.
