Abstract
The utility model relates to a leak-proof mechanical sealing for a pump and is characterized in that: a dynamic ring (2) and a static ring (5) are arranged on the same axial line; two friction end surfaces touch each other owing to elastic force support; the dynamic ring is arranged on a pump shaft (7) through a rotating seat (1); a seal groove (9) which is formed at the contact area between the dynamic ring and the rotating seat is sheathed with dynamic ring sealing ring (3); the static ring is arranged in a pump cover (4) in a suspension way, and a pump cover seal groove (8) is internally sheathed with a static ring sealing ring (6); both the dynamic ring sealing ring (3) and the static ring sealing ring (6) are respectively touched with the seal grooves (9) and (8) fully. Thereby, an elastic fixateur is formed between the dynamic ring sealing ring and the static ring sealing ring, and the fixateur does not sway in the seal groove, thus reaching the multiple sealing effect, eliminating the leak of liquid, improving sealing performance and ensuring the long-term stable running of the pump.
Description
Technical field
The utility model relates to a kind of mechanical seal for pump, is applicable to that the nothing of chemical pump and pollution discharge pump is revealed mechanical seal.
Background technique
Existing chemical pump or pollution discharge pump, because the groove depth of dynamic and static ring seal ring, groove width are not strict with, the seal ring of installing in use, can swing because of the size variation of carrying fluid pressure and cooling liquid pressure, easily produce chemical liquid and sewage and leak, cause the generation of environmental pollution or other accident.
Summary of the invention
In order to overcome the shortcoming that prior art exists, the purpose of this utility model provides a kind of good seal performance, long service life, dead-tight mechanical seal for pump.
The technical solution adopted in the utility model is: a kind of no-leakage pump mechanical seal, rotating ring and stationary ring are on the same shaft axis, two abrasive end faces are subjected to resilient support and contact, rotating ring is installed on the pump shaft through rotating seat, be with seal ring of moving ring in the seal groove that rotating ring and rotating seat contacting point form, stationary ring is outstanding to be loaded in the pump cover, be with the stationary ring seal ring in the pump cover seal groove at outstanding dress place, the external diameter of described seal ring of moving ring and stationary ring seal ring directly contacts with at the bottom of the seal groove of footpath at the bottom of the seal groove of rotating seat and pump cover respectively; The internal diameter of seal ring of moving ring and stationary ring seal ring contacts with the cylindrical of rotating ring and the cylindrical of stationary ring respectively; Seal ring of moving ring and stationary ring seal ring bi-side contact with the bi-side of seal groove respectively.
The shaft section of described stationary ring seal ring and seal ring of moving ring is shaped as circle or ellipse.
After adopting technique scheme, seal ring of moving ring contacts with the cylindrical and the seal groove another side of footpath at the bottom of the seal groove of rotating seat and seal groove one side, rotating ring under the elastic force effect of spring, promptly realizes that with seal groove the four sides contacts; The pump cover seal groove is determined according to the sectional area size of stationary ring seal ring, after being installed, the stationary ring seal ring can contact with the footpath, the end and the seal groove bi-side thereof of pump cover seal groove, the stationary ring seal ring is held tightly on the stationary ring cylindrical because of the elastic force metamorphosis simultaneously, promptly realizes that with seal groove the four sides contacts.Seal ring of moving ring and stationary ring seal ring have formed the flexible fastening body thus, can not swing in seal groove, reach the effect of multidimensional seal, have stopped the leakage of liquid, have improved sealability, have guaranteed the long-term stability running of equipment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of no-leakage pump mechanical seal as shown in Figure 1, rotating ring 2 and stationary ring 5 are on the same shaft axis, two abrasive end faces are subjected to resilient support and contact, rotating ring 2 is installed on the pump shaft 7 through rotating seat 1, be with seal ring of moving ring 3 in the seal groove 9 of rotating ring and rotating seat contacting point, seal ring of moving ring 3 is under the elastic force effect of spring, contact with the cylindrical and seal groove 9 another sides of footpath, 9 ends of seal groove of rotating seat and seal groove 9 one sides, rotating ring 2, seal ring of moving ring is placed in the seal groove, and contact fully with seal groove 9 four sides.Stationary ring 5 outstanding being loaded in the pump cover 4, be with stationary ring seal ring 6 between stationary ring cylindrical and the pump cover seal groove 8, stationary ring seal groove 8 is determined according to the sectional area size of seal ring, after being installed, stationary ring seal ring 6 can contact with the footpath, the end and seal groove 8 bi-side thereof of pump cover seal groove 8, seal ring is held tightly on stationary ring 5 cylindricals simultaneously, and stationary ring seal ring 6 is contacted fully with seal groove 8 four sides.
During work, rotating seat rotates with pump shaft, is subjected to the effect of seal ring of moving ring four sides elasticity to drive rotating ring and rotates together, because seal ring of moving ring contacts with the four-side elastic of seal groove, make sealed liquid can not pass through the seal ring of moving ring seepage, realize the sealing at seal ring of moving ring place; Stationary ring seal ring in the pump cover seal groove is subjected to resiliently deformable behind the pump shaft of packing into, make at the bottom of stationary ring seal ring and the pump cover seal groove and its bi-side and stationary ring cylindrical Elastic Contact, make seal fluid also can not pass through stationary ring seal ring seepage, realize the sealing at stationary ring seal ring place.
Claims (2)
1, a kind of no-leakage pump mechanical seal, rotating ring (2) and stationary ring (5) are on the same shaft axis, two abrasive end faces are subjected to resilient support and contact, rotating ring is installed on the pump shaft (7) through rotating seat (1), be with seal ring of moving ring (3) in the seal groove (9) that rotating ring and rotating seat contacting point form, stationary ring is outstanding to be loaded in the pump cover (4), be with stationary ring seal ring (6) in the pump cover seal groove (8) at outstanding dress place, it is characterized in that: the external diameter of seal ring of moving ring (3) and stationary ring seal ring (6) directly contacts with the footpath, seal groove (9) end of rotating seat and seal groove (8) end of pump cover respectively; The internal diameter of seal ring of moving ring and stationary ring seal ring contacts with the cylindrical of rotating ring (2) and the cylindrical of stationary ring (5) respectively; Seal ring of moving ring and stationary ring seal ring bi-side contact with the bi-side of seal groove (9) (8) respectively.
2, no-leakage pump mechanical seal according to claim 1, it is characterized in that: the shaft section of stationary ring seal ring and seal ring of moving ring is shaped as circle or ellipse.
