Abstract
The utility model discloses a shaft seal arrangement, including the main shaft and pass the casing of main shaft, be equipped with pressure disk and master in the casing, the master with cyclic annular atmoseal ring has between the main shaft, the ring of atmoseal ring is equipped with the passageway of ventilating on week, a passageway and the air duct of ventilating communicates with each other, one deck or two -layer graphite packing are respectively established to the both sides of atmoseal ring, it is equipped with the sealing ring in the passageway to ventilate, the sealing ring encircle in main shaft circumference. The utility model discloses a shaft seal arrangement is sealed effectual, install comparatively simple, long service life.
Description
Technical field
This utility model relates to a kind of shaft sealer.
Background technology
Blower fan can be divided into pressure fan, exhaust blower, centrifugal blower and circulating fan etc. multiple according to purposes, as the rotating machinery that a class is common, in most cases, the sealing of blower fan need not the tightest, but under certain special operation condition, such as high temperature, the circulating fan of explosion hazard gases, then the strictest to sealing requirements.
Sealing is divided into axial seal and circumferential seal, and the seal point of blower fan is mainly axial seal, and fan shaft is in high speed rotating state the most all the time, and sealing at this moment just becomes relatively difficult.Being sealed with of high-speed fan is a variety of, but sealing effectiveness is not fine, and sealing device is fragile, increases cost.At present, the solution also not had.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of shaft sealer.
For solving technical problem of the present utility model, the technical solution adopted in the utility model is:
A kind of shaft sealer, including main shaft and through the casing of main shaft, platen and master it is provided with in described casing, there is between described master and described main shaft ring-type sealing gland ring, the ring week of described sealing gland ring is provided with venting channels, described venting channels and an airway and communicates, and the both sides of described sealing gland ring respectively set one layer or two-layer graphite packing, being provided with sealing ring in described venting channels, described sealing ring is surrounded on described main shaft circumference.
Preferably, the both sides of described sealing gland ring respectively set two-layer graphite packing.
Preferably, described sealing ring is graphite-seal ring.This graphite-seal ring preferred high-density graphite sealing ring.
Preferably, described sealing gland ring is rigidity sealing gland ring.
Preferably, described venting channels has the internal diameter that the big outer layer of internal layer is little.
Preferably, described platen and described master are equipped with installation fixing hole.
Compared with prior art, the beneficial effect that this utility model is reached:
In venting channels, it is passed through the noble gas of certain pressure by airway when equipment uses, such as nitrogen, main shaft is formed radial pressure, graphite-seal ring further enhances sealing effectiveness simultaneously, farthest fan shaft is sealed, graphite-seal ring has good wearability and slickness, and in use will not produce heat or electrostatic；
Shaft sealer good sealing effect of the present utility model, installs relatively simple, and service life is long.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Wherein: 1. main shaft, 2. platen, 3. master, 4. sealing gland ring, 41. venting channels, 42. airways, 5. sealing ring, 6. graphite packing, fixing hole is 7. installed.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.Following example are only used for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of shaft sealer, including main shaft 1 and through the casing of main shaft 1, it is provided with platen 2 and master 3 in described casing, there is between described master 3 and described main shaft 1 ring-type sealing gland ring 4, the ring week of described sealing gland ring 4 be provided with venting channels 41, described venting channels 41 communicates with an airway 42, the both sides of described sealing gland ring 4 respectively set one layer of graphite packing 6, are provided with sealing ring 5 in described venting channels 41, and described sealing ring 5 is surrounded on described main shaft 1 circumference.
Further, described sealing ring 5 is high-density graphite sealing ring.High-density graphite sealing ring has good wearability and slickness, and in use will not produce heat or electrostatic.
Further, described sealing gland ring 4 is rigidity sealing gland ring.
Further, described venting channels 41 has the internal diameter that the big outer layer of internal layer is little.
Further, described platen 2 and described master 3 are equipped with installation fixing hole 7.Master 3 and platen 2 can be joined with bolts by this installation fixing hole 7.
In venting channels, it is passed through the nitrogen of certain pressure by airway when equipment uses, nitrogen is noble gas, main shaft can be formed radial pressure, graphite packing plays certain sealing effectiveness, prevent nitrogen from leaking vertically, graphite-seal ring further enhances sealing effectiveness simultaneously, farthest seals fan shaft.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; on the premise of without departing from this utility model know-why; can also make some improvement and deformation, these improve and deformation also should be regarded as protection domain of the present utility model.
Claims (6)
