Abstract
The utility model discloses a seal device which is a moving seal used in mechanical and chemical engineering industries for overcoming the disadvantages that the current seal device is complex in assembly and is not applicable for high position seal. The utility model comprises a stationary ring stationary on a base and a moving ring fixedly sleeved on a main shaft; wherein the stationary ring is made from material which can be attached by magnetic force while the moving ring is made from material which can not be attached by magnetic force; at least one circle of magnetic balls and at least one circle of graphite are fixedly embedded in the sealed end face of the moving ring and the graphite are extended out of the end face of the moving ring; the end face height of the magnetic balls is lower than that of the graphite. The utility model is convenient for assembly and the stationary ring can be attached by the magnetic balls, therefore the end face of the stationary ring can be tightly pressed by the graphite in the end face of the moving ring to achieve good seal effect.
Description
Affiliated technical field
The utility model relates to a kind of dynamic seal apparatus.
Background technique
In various pulverizing occasions, in order not make industrial chemicals or lubricant grease contaminated or do not leak, all need use various motive sealings, it is to constitute like this that a kind of motive sealing is arranged at present: rotating ring one end fixing spring, make spring keep enough elastic force, like this during the rotating ring high speed rotating, owing to the existence of elastic force, make the rotating ring end face press the stationary ring end face, so just played seal action.The assembling of this seal arrangement one is complicated, and it two takes up room greatly, make to be not suitable for high-order sealing, and As time goes on, because spring is aging, sealing can weaken.
Summary of the invention
In order to overcome existing seal arrangement assembling complexity and not to be suitable for the high-order deficiency that seals.The utility model provides a kind of seal arrangement, and the assembling of sealing device is easy, and long service life.
The utility model for the technological scheme that solves its technical problem and adopt is: it comprises the rotating ring that the stationary ring that is fixed in pedestal and fixed cover are located at main shaft, stationary ring is by being constituted by the material of magnetic attraction, rotating ring is by not constituted by the material of magnetic attraction, at least a fixedly embedded circle magnetic bead and a circle graphite on the rotating ring seal face, graphite stretches out the rotating ring end face, and the end face height of magnetic bead is lower than the end face height of graphite.
Magnetic bead is distributed in distance, and graphite is continuous arrangement.
Be provided with the L RunddichtringO of being made by rubber between rotating ring and main shaft, the L RunddichtringO can increase driving torque, can reach the purpose of axially not leaking.
Stationary ring is made by Martensitic Stain Less Steel or carbon steel material, and rotating ring is that Austenitic Stainless Steel or copper product are made.
The beneficial effects of the utility model are: earlier that magnetic bead and graphite is fixedly embedded in the rotating ring end face during assembling, and then rotating ring is fixed in main shaft, assembling easily like this, can be attracted by magnetic bead owing to stationary ring again, therefore, rotating ring is when running up, and the graphite of rotating ring end face can press the stationary ring end face, good sealing effect can be played, and sealing effect can be kept for a long time; Again, this mounting type of magnetic bead has shortened mounting distance, makes the utility model can be used for high-order sealing.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
Embodiment
Embodiment: referring to Fig. 1, a kind of seal arrangement, stationary ring 2 is fixed in pedestal, be provided with O RunddichtringO 3 between stationary ring 2 sides and pedestal, stationary ring 2 end faces are smooth smooth, stationary ring 2 is made by Martensitic Stain Less Steel or carbon steel material, be that stationary ring 2 is by being constituted by the material of magnetic attraction, rotating ring 5 fixed covers are located at main shaft, be provided with the L RunddichtringO of making by rubber 6 between rotating ring 5 and main shaft, L RunddichtringO 6 can increase driving torque, can reach the purpose of axially not leaking, rotating ring 5 is made for austenitic stainless steel material, and promptly rotating ring 5 is by not constituted by the material of magnetic attraction, the magnetic bead 4 of the discontinuous arrangement of a fixedly embedded circle on rotating ring 5 seal faces, and the continuous graphite 1 of a fixedly embedded circle on rotating ring 5 seal faces, graphite 1 and magnetic bead 4 are in the diverse location on rotating ring 5 end faces, and graphite 1 stretches out rotating ring 5 end faces, magnetic bead 4 is absorbed in the end face or magnetic bead 4 stretches out the length that the length of rotating ring 5 end faces is stretched out rotating ring 5 end faces less than graphite 1, and magnetic bead 4 can not touch stationary ring 2 end faces like this.
Working principle of the present utility model is: because magnetic bead 4 can attract stationary ring 2 tightly, make rotating ring 5 that the active force of past stationary ring 2 directions motion be arranged, graphite 1 can press stationary ring 2 end faces like this, and rotating ring 5 material can not occur and leak between the end face seal of stationary ring 2 and rotating ring 5 in the process of running up.
Claims (5)
1. seal arrangement, comprise the rotating ring that the stationary ring that is fixed in pedestal and fixed cover are located at main shaft, it is characterized in that: stationary ring is by being constituted by the material of magnetic attraction, rotating ring is by not constituted by the material of magnetic attraction, at least a fixedly embedded circle magnetic bead and a circle graphite on the rotating ring seal face, graphite stretches out the rotating ring end face, and the end face height of magnetic bead is lower than the end face height of graphite.
2. seal arrangement according to claim 1, it is characterized in that: magnetic bead is distributed in distance, and graphite is continuous arrangement.
