Description
Technical field
The present invention relates to a kind of packaging sealing device, particularly relate in a kind of rotating machinery that can be applicable to the lower sealing occasion of manufacture process pressure, promote multi-segment ring packaging sealing device the manufacture process fluid anti-leak function of device fabrication process side.
Background technique
For prevent the manufacture process fluid via the slot leakage between equipment parts and transmission shaft to atmospheric side, equipment generally can be installed one group of gland seal device in its casing end, provide this transmission shaft rotatably to be pivoted wherein, and fit to mill, in the hope of reaching the purpose that prevents that the manufacture process fluid from leaking by the seal ring in this gland seal device.
At present existing known cartridge seal device mainly is to have a capsule body, an axle sleeve and several seal rings, this axle sleeve is to be hubbed in this capsule body, and provide transmission shaft to wear wherein, axle sleeve can together be rotated with transmission shaft, these several seal rings are to be installed in this capsule body inside, and seal ring is a monolithic design, and is sheathed on this axle sleeve outside.
In addition, in the aforesaid gland seal device, because of its seal ring is a complete ring design, when seal ring is changed, must can't directly on rotating machinery, keep in repair with axle capsule body and seal ring in the gland seal device by pulling down on the rotating machinery, cause the operation inconvenience of part exchanging and maintenance.
In another known axes seal apparatus design, its seal ring is all the multi-segment ring design of 3 chips, the ring monomer modal shift of those multi-segment rings (ring body monomer junction shape difference), and how described multistage ring is separately set in the equipment fully, can't be balanced compensated voluntarily by structure itself, so that the sealing between seal ring and equipment transmission shaft or seal ring and axle capsule body is not good, thereby, the manufacture process fluid of this gland seal device one side is flowed towards the atmospheric side direction via the slit of seal ring and shaft room, can't keep its due anti-leak function.
And, the sealing ring is installed in the cartridge seal device by in the housing of atmospheric side, directly contact with transmission shaft, do not have the function of automatic axial and radial position compensation, so after seal ring uses a period of time, during because of seal ring and transmission shaft rotation abrasion with the pressure compensation deviation post, make the slit between transmission shaft and seal ring become big, influence the sealing between seal ring and transmission shaft, promptly must put in order the group seal ring and be renewed, so that seal ring there is short partially problem in working life.When mounted, the seal ring group need be installed one by one and insert a capsule body inside, compare, need expend the more installation time during installation, artificial careless mistake also takes place easily with the whole assembly and disassembly structure of general cartridge seal device.
This shows that above-mentioned existing gland seal device obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the problem of above-mentioned existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of multi-segment ring packaging sealing device of new structure, real one of the current important research and development problem that belongs to, also becoming the current industry utmost point needs improved target.
