Abstract
The utility model belongs to the technical field of pump body seal assembly, concretely relates to directly ally oneself with pump dress double mechanical seal's tail-hood device. This directly ally oneself with pump dress double mechanical seal's tail-hood device, including gland and tail-hood, it is equipped with the gland to lie in sealed chamber one side on the tail-hood, and one side is equipped with the stationary ring seat in addition, through screw rod and nut fastening connection between gland and stationary ring seat and the tail-hood, is equipped with first mechanical seal stationary ring and second mechanical seal stationary ring on the motor shaft that lies in the sealed intracavity. The beneficial effects are as follows: the problem of can't use the double mechanical seal on horizontal directly allies oneself with the pump is solved, make horizontal directly allies oneself with the pump and adopts double mechanical seal to become possible, and reasonable in design, simple structure has saved the axle sleeve thereby has reduced sealed link, makes the adaptation operating mode scope of directly alliing oneself with the pump bigger.
Description
Technical Field
The utility model belongs to the technical field of pump body seal assembly, concretely relates to directly ally oneself with pump dress double mechanical seal's tail-hood device.
Background
At present, in the industry, direct-coupled pumps are all arranged in a single-end-face mechanical seal mode, and products adopting double-end-face mechanical seal are almost not adopted. Under some special working conditions, the medium is inflammable, explosive, high-temperature, strong in corrosivity, strong in pollution and the like, and the sealing effect of the double-end-face mechanical seal is obviously better than that of a single-end-face mechanical seal. When the working condition needs double-end-face sealing, the direct connection pump with smaller floor area and more compact structure can not be selected due to structural limitation, and only the suspension type or bracket type horizontal centrifugal pump with larger floor area, more complex structure and higher use cost can be selected.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a remedy prior art's defect, provide a directly ally oneself with pump dress double mechanical seal's tail-hood device.
The utility model discloses a realize through following technical scheme:
the utility model provides a direct-coupled pump dress double mechanical seal's tail-hood device, includes gland and tail-hood, it is equipped with the gland to lie in sealed chamber one side on the tail-hood, and one side is equipped with the stationary ring seat in addition, through screw rod and nut fastening connection between gland and stationary ring seat and the tail-hood, is equipped with first mechanical seal stationary ring and second mechanical seal stationary ring on the motor shaft that lies in sealed intracavity.
Furthermore, the gland, the stationary ring seat and the tail cover are fixedly connected through four screw rods.
Furthermore, the first mechanical seal static ring and the second mechanical seal static ring are respectively pressed on the motor shaft in the sealing cavity through the static ring seat and the gland.
Furthermore, the static ring seat, the gland and the tail cover are sealed through sealing glue.
The utility model has the advantages that: the problem of can't use the double mechanical seal on horizontal directly allies oneself with the pump is solved, make horizontal directly allies oneself with the pump and adopts double mechanical seal to become possible, and reasonable in design, simple structure has saved the axle sleeve thereby has reduced sealed link, makes the adaptation operating mode scope of directly alliing oneself with the pump bigger.

Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1 stationary ring seat, 2 first mechanical seal stationary rings, 3 tail covers, 4 second mechanical seal stationary rings, 5 screw rods, 6 gland covers, 7 nuts and 8 motor shafts. 9 sealing the cavity.
Detailed Description
Fig. 1 shows an embodiment of the present invention. The utility model discloses a directly ally oneself with pump dress double mechanical seal's tail-hood device, including gland 6 and tail-hood 3, it is equipped with gland 6 to lie in sealed chamber 9 one side on the tail-hood 3, and one side is equipped with quiet ring holder 1 in addition, through screw rod 5 and nut 7 fastening connection between gland 6 and quiet ring holder 1 and the tail-hood 3, is equipped with first mechanical seal quiet ring 2 and second mechanical seal quiet ring 4 on the motor shaft 8 that lies in sealed chamber 9.
Further, the gland 6 and the stationary ring seat 1 are fixedly connected with the tail cover 3 through four screw rods 5.
Further, the first mechanical seal static ring 2 and the second mechanical seal static ring 4 are respectively pressed on a motor shaft 8 in a seal cavity 9 through a static ring seat 1 and a gland 6.
Furthermore, the stationary ring seat 1, the gland 6 and the tail cover 3 are sealed by sealant.
The utility model discloses a directly ally oneself with pump dress double mechanical seal's tail-hood device, the quiet ring seat 1 that will install two quiet rings all designs into separable structure, thereby it is possible to make directly ally oneself with pump join in marriage double mechanical seal, double mechanical seal is established ties the installation back to back by two sets of UW type single-ended mechanical seal in figure 1, the rotating ring pastes the rotating ring promptly and is constituteed, two mechanical seal quiet rings that correspond are all installed on the quiet ring seat 1 and the gland 6 separable with tail-hood 3, the rotating ring does not have locking screw, utilize two sets of intra-annular respective spring pressure automatic compensation to reach the pressure balance on two sealing end faces, four screw rods 5 pass tail-hood 3 and the quiet ring seat 1 and the gland 6 hookup of both sides simultaneously with nut 7 fixed, seal between quiet ring seat 1 and gland 6 and tail-hood 3 is equipped with sealed glue by the laminating terminal surface and realizes.
The present invention is not limited to the above embodiments, and any person should learn to make under the teaching of the present invention and the present invention has the same or similar technical solution, and all fall into the protection scope of the present invention.
The technology, shape and construction parts which are not described in detail in the present invention are all known technology.
