Abstract
The utility model discloses a sealing device for automobile engine cooling water pump, including axle sleeve, rotatory ring, stationary ring, bellows and bellows fixing base, be equipped with packing ring and lower packing ring on the casing in cooling water pump's pivot exit go up the packing ring and install corrugated header, bellows and spring down between the packing ring, be equipped with the stationary ring between the casing in bellows fixing base and cooling water pump pivot exit, the axle sleeve is pegged graft be equipped with the axle sleeve in cooling water pump's the pivot the axle sleeve outside is equipped with the rotatory ring with stationary ring sealing contact, rotatory ring with stationary ring contact department is equipped with prevents string recess. The utility model discloses an auxiliary seal circle is the sealing washer of elastic material's preparation, when high -speed rotation, can apply certain elasticity to the stationary ring, the contact plane of rotatory ring more can guarantee the tight seal under ripple tube spring's elastic reaction, because the rotatory ring of pottery is lived to elastic auxiliary seal circle parcel, the rotatory ring of pottery has certain elastic space has increased adaptive promptly, and then not fragile sealed face results in leaking.
Description
Technical field
This utility model relates to the gland seal device of a kind of pump housing, goes up a kind of sealing device for automobile engine cooling water pump specifically, belongs to cooling pump manufacturing technology field.
Background technology
The rotatory sealing of automobile cooling water pump also uses mechanical seal, and by machine driving, due to the wide ranges of its rotating speed, even can reach the order of magnitude of per minute ten thousand turns during high speed.Requirement with common chemical industry mechanical seal is different, uses the good contact of graphite stationary ring and carborundum rotating ring plane, be aided with the auxiliary device such as axle sleeve, by the supporting and fixing the most therewith of carborundum rotating ring in prior art；The stationary ring, rotating ring, axle sleeve and the gland that seal and auxiliary seal are main components；Graphite stationary ring and the sealing plane of carborundum rotating ring are the sealing surfaces that requirement is the highest, it is desirable to the most still ensure to seal, especially during high speed rotating.Although corrugated tube has certain elasticity, but rotating ring and the axle sleeve installing rotating ring are all rigid component with gland, when the rotational speed is high, stationary ring, rotating ring contact plane can not be at the tight seal ensured under the elastic reaction of bellows springs, more importantly it is easily damaged sealing surface, causing leakage, the reason of the latter is difficult to cause the attention of industry, thus causes the life-span of existing water pump can not reach expection.
Utility model content
Technical problem to be solved in the utility model is, the shortcoming overcoming prior art, it is provided that a kind of sealing device for automobile engine cooling water pump, it is possible to extend the service life of water pump largely, vibration during reduction pump working and noise.
In order to solve above technical problem, this utility model provides a kind of sealing device for automobile engine cooling water pump, including axle sleeve, rotating ring, stationary ring, seat fixed by corrugated tube and corrugated tube, the housing in the rotating shaft exit of cooling water pump is provided with upper gasket and lower gasket, corrugated header is installed between described upper gasket and lower gasket, corrugated tube and spring, described corrugated tube is fixed and is provided with stationary ring between the housing in seat and cooling water pump rotating shaft exit, described axle sleeve is plugged on the rotating shaft of described cooling water pump and is provided with axle sleeve, the rotating ring being in sealing contact with stationary ring it is provided with outside described axle sleeve, described rotating ring and described stationary ring contact position are provided with anti-string groove.
The technical scheme that this utility model limits further is: be previously described for the sealing device of automobile engine cooling water pump, the cross section structure in T shape of described stationary ring, the symmetrical boss side of this stationary ring two is connected to corrugated tube and fixes between seat and housing, and opposite side is in close contact with the anti-string groove on described rotating ring.
Being previously described for the sealing device of automobile engine cooling water pump, the end of described axle sleeve is provided with turnup structure, is coated and fixed by described rotating ring by described turnup structure.
It is previously described for the sealing device of automobile engine cooling water pump, also sets up, between described rotating ring and described axle sleeve turnup structure, the auxiliary seal ring being made up of elastomeric material.
Further, it is previously described for the sealing device of automobile engine cooling water pump, in the gap between described stationary ring and axle sleeve, fills graphite airtight and watertight padding.
The beneficial effects of the utility model are: auxiliary seal ring of the present utility model is the sealing ring of the preparation of elastomeric material, when the rotational speed is high, stationary ring can be applied certain elasticity；The contact plane of rotating ring more can guarantee that the tight seal under the elastic reaction of bellows springs, owing to elastic auxiliary seal ring wraps ceramic rotary change, ceramic rotary change has certain elastic space and i.e. adds adaptivity, then it is hardly damaged sealing surface and causes leakage, the most such at fast state；The groove mated with stationary ring is set on rotating ring simultaneously, sealing effectiveness can be improved further, and prevent the vibration between stationary ring and sealing ring, vibrations when can effectively reduce pump working and noise, so that the life-span of existing water pump reaches expection, apparently higher than existing product, the average life of water pump is made to be greatly prolonged, it is possible to reach the life-span of external high-quality high quality car water pump.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
