Description
Technical field
The present invention relates to a kind of seal arrangement, relate in particular to a kind of lip shape seal device.
Background technique
Lip seal is the interference fit by seal ring lip and axle sleeve, play the choked flow seal action at Static and dynamic, yet in use, because seal lip and axle sleeve high-speed friction, the imbalance that adds axle is beated, can cause the sealing cutting edge to wear and tear gradually, thereby cause the seal lip magnitude of interference to reduce, lip and shaft room pressure reduce or forfeiture, finally cause the total failure that seals, therefore the lip-type packing that need to more renew, actual sealing is shorter working life, and changes continually lip-type packing unusual effort for the maintenance man.
Summary of the invention
A technical problem to be solved by this invention is: provide a kind of and can prolong the sealing lip shape seal device in working life.
For solving the problems of the technologies described above, the present invention adopts following technological scheme: a kind of lip shape seal device, comprise: rotating shaft, be installed on the axle sleeve in the rotating shaft, be installed on the flange of axle sleeve one end and be installed on the slips of the axle sleeve the other end, oil sealing base and end cap are installed on the described axle sleeve, the top of described oil sealing base is provided with oil feeding device, the below of described oil sealing base is provided with oil discharging device, fix by several first bolts between described axle sleeve and the slips, be provided with O type circle between described axle sleeve and the slips, be provided with the first spring washer between described the first bolt and the slips, fix by several first screws between described oil sealing base and the end cap, be provided with the second spring washer between described the first screw and the end cap, fix by several second screws between described oil sealing base and the flange, be provided with the 3rd spring washer between described the second screw and the oil sealing base, the first lip-type packing is installed between described oil sealing base and the end cap, the second lip-type packing is installed between described oil sealing base and the flange, be arranged with the first extension spring in described the first lip-type packing, be arranged with the second extension spring in described the second lip-type packing.
Beneficial effect of the present invention: the present invention is by arranging the first lip-type packing and the second lip-type packing, at the beginning the first lip-type packing and axle sleeve interference fit, the second lip-type packing does not contact with axle sleeve, after operation a period of time, after the lip wearing and tearing of the first lip-type packing, can make the second lip-type packing and axle sleeve regain interference by moving axially axle sleeve, realize sealing, thereby prolonged sealing working life, also alleviated maintenance man's the amount of labour simultaneously.
