Abstract
The utility model discloses a mechanical seal structure for papermaking. The mechanical seal structure comprises a shaft sleeve and an end cover. A fixed ring is arranged between the shaft sleeve and the end cover. The end cover and the shaft sleeve are fixedly connected through a screw. The left end of the shaft sleeve is connected with a drive ring through a set screw. The right end of the drive ring is connected with a movable ring through a bolt. An O-shaped ring of the movable ring is arranged between the movable ring and the shaft sleeve. The right end of the movable ring is provided with a reinforcing part in an embedded mode. The right end of the reinforcing part is connected with the fixed ring in a top contacting mode. The left end of the reinforcing part is clamped with the movable ring. The reinforcing part is made of a hard alloy material. The mechanical seal structure has the advantages that the movable ring is provided with the hard alloy end face in an embedded mode, an original silicon carbide layer and a chromium oxide coating are replaced, and therefore the end face is high in rigidity and can not be broken easily. The mechanical seal structure is ingenious in design thought and excellent in effect, improves the reliability and prolongs the service life.
Description
Technical field
The utility model belongs to Sealing technical field, particularly a kind of papermaking equipment sealing configuration of paper industry.
Background technique
The end face material of the mechanical seal of paper making pulp industry is silicon carbide or chromium oxide substantially, the characteristic of silicon carbide is that hardness is high but more crisp, although and chromium oxide is not easy crackedly but surperficial easily to peel off, reclaims in paper pulp and contain a lot of foreign material, can damage above two kinds of end faces.
Model utility content
The purpose of this utility model is to provide a kind of novel papermaking equipment Sealing.
The technological scheme that the utility model is taked for its technical problem of solution is:
A kind of papermaking equipment sealing configuration, comprise axle sleeve and end cap, between axle sleeve and end cap, be provided with stationary ring, affixed by screw between described end cap and axle sleeve, axle sleeve left end is connected with a driving ring by Cock screw, and driving ring right-hand member has been bolted rotating ring, between rotating ring and axle sleeve, be provided with rotating ring O type circle, on rotating ring right-hand member, inlay a reinforcer, described reinforcer right-hand member contacts and is connected with described stationary ring, reinforcer left end and described rotating ring clamping.
Between described end cap and described stationary ring, be provided with stationary ring O type circle.
Between described driving ring and described rotating ring, be provided with spring, between spring and described rotating ring, be provided with spring pad, spring pad and described rotating ring left end are affixed, and spring is located at around described bolt, bolt and spring pad screw thread are affixed, and described bolt and described driving ring are slidably connected.
Described reinforcer is that cemented carbide material is made.
The beneficial effects of the utility model: the utility model takes the lead in adopting new seal face material in paper pulp industry, adopt the mode of insert that cemented carbide is installed on the rotating ring in stainless steel, because cemented carbide has, hardness is high is not easy cracked characteristic, makes it to become the good sealing material of pulp recovery.By insert cemented carbide end face on rotating ring, substitute original silicon carbide and chromium oxide coating, make the stronger hardness of end face maintenance and not cracked.The utility model mentality of designing exquisiteness, effect is outstanding, improves reliability, increases the service life.
Brief description of the drawings
Fig. 1 is structure sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of papermaking equipment sealing configuration as shown in Figure 1, it should be noted that, comprise axle sleeve 10 and end cap 11, between axle sleeve 10 and end cap 11, be provided with stationary ring 7, affixed by screw 12 between described end cap 11 and axle sleeve 10, axle sleeve 10 left ends are connected with a driving ring 1 by Cock screw 2, driving ring 1 right-hand member is connected with rotating ring 6 by bolt 8, between rotating ring 6 and axle sleeve 10, be provided with rotating ring O type circle 5, on rotating ring 6 right-hand members, inlay a reinforcer 13, described reinforcer 13 right-hand members contact and are connected with described stationary ring 7, reinforcer 13 left ends and described rotating ring 6 clampings.
Between described end cap 11 and described stationary ring 7, be provided with stationary ring O type circle 9.
Between described driving ring 1 and described rotating ring 6, be provided with spring 3, between spring 3 and described rotating ring 6, be provided with spring pad 4, spring pad 4 is affixed with described rotating ring 6 left ends, spring 3 is located at around described bolt 8, bolt 8 is affixed with spring pad 4 screw threads, and described bolt 8 is slidably connected with described driving ring 1.
Described reinforcer 13 is made for cemented carbide material.
The utility model takes the lead in adopting new seal face material in paper pulp industry, adopt the mode of insert that cemented carbide is installed on the rotating ring in stainless steel, because cemented carbide has, hardness is high is not easy cracked characteristic, makes it to become the good sealing material of pulp recovery.By insert cemented carbide end face on rotating ring, substitute original silicon carbide and chromium oxide coating, make the stronger hardness of end face maintenance and not cracked.The utility model mentality of designing exquisiteness, effect is outstanding, improves reliability, increases the service life.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope, those ordinary skill in the art's simple change and replacement are all within protection domain of the present utility model.
