Abstract
The utility model discloses a new structure for a mechanical sealing, which does not need to reduce friction radius but can reduce the pair sewing speed of friction, comprising a sealing device 1 and a stator ring 3 arranged in the terminal port 2 of a pump body. The utility model is characterized in that a relative moving ring 4 whose speed can be regulated discretionally is additionally arranged between the stator ring 3 and the moving rings 13 in the sealing device 1; the relative moving ring 4 is connected with the speed reducing mechanism 6 of a wheel train through a free seat 5; the speed reducing mechanism of the wheel train is connected to a free bearing seat 7 and a bearing 8 arranged in the free bearing seat; the speed reducing mechanism 6 of the wheel train and the sealing device 1 are connected with a shaft sleeve 19 through a transmission key 9; the outer parts of the sealing device 1 and the speed reducing mechanism 6 of the wheel train are provided with protective covers 10.
Description
The utility model relates to a kind of structure of mechanical seal, especially a kind of new structure of mechanical seal.
For a long time, the leakage problem that how to solve mechanical seal is a difficult problem always, and promptly present mechanical seal does not realize the function of sealing veritably, and equilibrium of forces and thermal equilibrium are the factors that directly influences mechanical seal.Be all can solve of the influence of equilibrium of forces problem well theoretically or in the practice now to mechanical seal, that is to say that the equilibrium of forces problem no longer is the principal element that influences mechanical seal, that is to say that so thermal balance question is the principal element that influences mechanical seal, and the linear velocity on the friction pair is the thermally equilibrated principal element of influence, because if the linear velocity on the friction pair is not equal to zero, then certainly lead to heat between friction pair, and the big more sealing effect of heat is just low more, therefore the linear velocity that reduces on the friction pair just becomes the matter of utmost importance that solves mechanical seal, the unique method that reduces linear velocity at present is to reduce friction radius, and the effect of doing so is not very desirable.
The purpose of this utility model will but can reduce the new structure of the mechanical seal of linear velocity on the friction pair for the user provides a kind of friction radius that need not to reduce exactly.
For achieving the above object, technical solution of the present utility model is: a kind of new structure of mechanical seal, it comprises seal arrangement 1 and the stationary ring 3 that places in the pump housing port 2, it is characterized in that: set up the relative rotating ring 4 of speed governing arbitrarily between the rotating ring 13 in stationary ring 3 and seal arrangement 1, rotating ring 4 is connected with train reducing gear 6 by free 5 relatively, what be connected with train reducing gear 6 is free axis bearing 7 and the bearing 8 that places in the free axis bearing 7, train reducing gear 6 and seal arrangement 1 are connected with axle sleeve 19 by transmission strong 9, are provided with protective housing 10 outside seal arrangement 1 and train reducing gear 6.
Described train reducing gear 6 adopts planetary gear reducing mechanism.
Described protective housing 10 is made up of support 11 that is connected with the pump housing and the end cap 12 that is connected with support 11.
Because the utility model is to have set up the train reducing gear on mechanical seal device, therefore can reduce the linear velocity on the friction pair, make the friction between friction pair realize boundary friction, but thereby the life-span of prolonged mechanical sealing, and can adopt the face pressure that is fit to performance flexibly, the utility model is applicable to different occasions, and all can realize the favorable mechanical sealing.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure, in pump housing port 2, be provided with stationary ring 3, what join with stationary ring 3 is relative rotating ring 4, be that stationary ring 3 forms friction pair with the end face of relative rotating ring 4, contact with rotating ring 13 in the seal arrangement 1 at the paraxial place of relative rotating ring 4, outer end at relative rotating ring 4 links into an integrated entity by driving lever 14 and free seat 5, the other end of free seat 5 by bearing shaft 16 and on bearing 17 be connected with planetary gear reducing mechanism 6, the position of this planetary gear reducing mechanism 6 can be installed as required flexibly, retainer 15 in it and the seal arrangement 1 links together by driving key 9 and axle sleeve 19, free axis bearing 7 is connected with bearing shaft 16, bearing 8 is installed in free axis bearing 7, to guarantee that relative rotating ring 4 reaches equilibrium of forces, certainly free axis bearing 7 also can be made an integral body with free seat 5, for the ease of installing and maintenance, they are divided into two bodies, free axis bearing 7 and be installed on the position of bearing 8 wherein neither be changeless, can determine its position as the case may be, protective housing 10 is installed outside whole sealing device, it is by the support 11 that is connected with the pump housing, and end cap 12 compositions that are connected with support 11.
When the transmission shaft high speed rotating, deceleration by planetary gear reducing mechanism 6, and the rotating speed of relative rotating ring 4 is reduced, be that relative rotating ring 4 is with respect to the rotating speed between stationary ring 3 end faces, and relative rotating ring 4 has all reduced with respect to the rotating speed between rotating ring 13 end faces, that is to say that the linear velocity between friction pair is significantly less than the linear velocity between friction pair in the existing seal arrangement, therefore the performance of the new structure mechanical seal of this mechanical seal of the present utility model is fine, and can be as required, if reduction of speed, a train reducing gear promptly only is installed is not reached the words of seal request, can install two, even a plurality of train reducing gear, carry out repeatedly reduction of speed, until making the linear velocity between friction pair reach requirement, to realize the favorable mechanical sealing.
