Becoming, the sealing principle of axle envelope is hermetic seal principle, and this kind of sealing means is typically dyanainic friction ring with graphite, and static friction ring material is
Carborundum, the rotating speed of start axle is the highest, will result in axle end-blocking surface temperature and quickly improves, may reach rotating ring and stationary ring end face
Burning red, after starting shooting 10 seconds, refrigeration oil just can be sprayed onto the surface of rotating ring and stationary ring, and now cold oil sprays to burn red sealing surfaces, quickly
Cooling so that graphite annulus is splashed swollen with carborundum sealing surface, easily causes the fracture phenomena of seal face, the service life of material
Short, meanwhile, if shaft seal structure is hermetic seal, because sealing gas working medium is freon, the molecular structure of freon is a kind of
Easy to leak molecule, once the working time is permanent, will easily leak, and relative refrigeration system reliability brings impact, to this end,
It is proposed that a kind of more convenient and mechanical shaft seal of good airproof performance.

Pin, gland, stationary ring and the second sealing ring, the top layer of described rubber ring is provided with fixing screw, and the top of rubber ring is fixed
There are slip ring, the outer ring of described slip ring to be inlaid with the first sealing ring, and the top side of slip ring is provided with bolt, described bolt
Top is provided with spring, and the top of spring is connected with shaft seal cavity, and the bottom of described shaft seal cavity is provided with liquid injection hole, and fluid injection
The top in hole is mounted with the first corrugated tube, and the left side of described first corrugated tube is provided with the second corrugated tube, the top of described shaft seal cavity
Side is provided with gland, and the upper end of described gland is inlaid with stationary ring, and the top of stationary ring is provided with the second sealing ring.
Preferably, the surface configuration of described first corrugated tube and the second corrugated tube has thread groove.
Preferably, described spring is Collapsible structure, and its telescopic extensions is 0-5cm.
Preferably, the upper end of described shaft seal cavity is fixed with stop pin.
Preferably, the outer ring of described liquid injection hole is provided with anticorrosive coat.
Compared with prior art, the beneficial effects of the utility model are: this mechanical shaft seal is provided with liquid injection hole, it is possible to axle
Envelope intracavity injects liquid, thus produces a thin film and strengthen its sealing, and secondly arranging of stop pin can allow gland fix,
Make it be not easy to rotate, and its spring when sealing, can play the effect of a buffering, substantially increases the fault-tolerant of axle envelope
Property.
