Abstract
The utility model relates to an anti-rotation device in cartridge-type double-end surface magnetic oil sealing, which comprises a movable ring, a static ring fixedly connected with equipment, a sealing seat, and an anti-static magnetic column seat and a permanent seat arranged between the sealing seat and the movable ring, and is characterized in that the inner side of the sealing seat is provided with a boss which is integrated with the sealing seat; and the boss is inserted into a groove of the anti-static magnetic column seat. By adopting the integral structure, the device enhances the strength of the boss with an anti-pin rotation function, and ensures the relative positions of the anti-static magnetic column seat and the sealing seat are not changed. Therefore, by adopting the transmission mode, the anti-rotation device in cartridge-type double-end surface magnetic oil sealing is convenient to process and manufacture, has high strength and long service, and has the advantages of simple structure, compact space size, ensuring of the sealing performance of the whole mechanical sealing process and the like.
Description
Technical field
The utility model belongs to the mechanical sealing technology field, particularly relates to the anti-rotation device in a kind of unit loading type Double End Magnetic oil seal.
Background technique
Mechanical seal is a kind of seal arrangement that prevents that working fluid from leaking along running shaft, it is mainly sealed by the sealing surface that stationary ring and rotating ring form, stationary ring is connected with main shaft with equipment respectively by its link with rotating ring, the fitting surface of stationary ring and rotating ring is in the state of fitting tightly all the time in relative rotary course, stop medium to pass through, thereby reach the purpose of sealing.The rotating ring that is sleeved in rotary course on the transmission shaft rotates with main shaft, in order to guarantee between the rotating ring and antistatic mangetic rod base the servo-actuated phenomenon not to take place when rotated, a stop pin is welded in existing main employing on sealing seat, stop pin is connected with the antistatic mangetic rod base, guarantees that by the stop pin that welds servo-actuated does not take place for rotating ring and antistatic mangetic rod base.Because stop pin is subjected to a shearing force all the time in whole rotary course, the long-time use makes the stop pin that is welded on the driving sleeve come off easily, thereby cause rotating ring to rotate with the antistatic mangetic rod base, and then cause rotating ring and antistatic mangetic rod base impaired, particle after the wearing and tearing may enter rubbing surface between rotating ring and the stationary ring along with rotation, because wearing and tearing for a long time, finally cause the leakage of whole mechanical seal, therefore adopt the above-mentioned kind of drive to have deficiencies such as processed complex, intensity is little, working life is short.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, easily manufactured, transmission is effective, anti-rotation device in the unit loading type Double End Magnetic oil seal of long service life.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Anti-rotation device in a kind of unit loading type Double End Magnetic oil seal, comprise the rotating ring that rotates with main shaft, the stationary ring of fixedlying connected with equipment, sealing seat and be installed in sealing seat and rotating ring between antistatic mangetic rod base and permanent magnet, it is characterized in that: it is the boss of one that described sealing seat inboard is shaped on sealing seat, and boss is inserted in the groove of antistatic mangetic rod base.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, promptly being shaped on sealing seat in the sealing seat inboard is the boss of one, and boss is inserted in the groove of mangetic rod base.Adopt the feasible intensity of integral structure to be strengthened, guarantee rotating ring and the not servo-actuated when rotated of antistatic mangetic rod base with boss of stop pin function.Therefore said structure convenient processing and manufacture, big, the long service life of intensity; In addition the utility model also have simple in structure, bulk is compact, guarantee the advantages such as sealability of whole mechanical seal.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an A-A sectional view among Fig. 1.
Among the figure: 1, rotating ring; 2, stationary ring; 3, sealing seat; 3-1, boss; 4, antistatic mangetic rod base; 5, permanent magnet.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Embodiment:
See also Fig. 1 and Fig. 2, anti-rotation device in a kind of unit loading type Double End Magnetic oil seal, comprise the rotating ring 1 that rotates with main shaft, the stationary ring 2 of fixedlying connected with equipment, sealing seat 3 and be installed in sealing seat 3 and rotating ring 1 between antistatic mangetic rod base 4 and permanent magnet 5, it is characterized in that: described sealing seat 3 inboards are shaped on sealing seat 3 and are the boss 3-1 of one, and boss 3-1 is inserted in the groove of antistatic mangetic rod base 4.Adopt the feasible intensity of integrative-structure to be strengthened, guarantee that the relative position between antistatic mangetic rod base and the sealing seat does not change with boss of stop pin function.Therefore adopt above-mentioned kind of drive convenient processing and manufacture, big, the long service life of intensity; In addition the utility model also have simple in structure, bulk is compact, guarantee the advantages such as sealability of whole mechanical seal.
