Description
Technical field
A kind of large-diameter mechanically-sealing apparatus is the utility model is related to, suitable for high-capacity pump class product.
Background technology
With the rapid development of modern industry, the trend risen is presented to the demand of high-capacity pump class product in market, therewith
Supporting large-diameter（≥250mm）Mixed flow pump mechanical sealing is because the attrition process difficulty of sealing ring is big, requires height, risk greatly
Feature is always the technological difficulties of domestic mechanical seal industry.The mechanical seal of supporting large-diameter all uses imported product, the skill
Art is at home still in blank, therefore the product has wide market prospects.
The product is compared with other serial machine envelope products：With complex designing, volume size is big, requirement on machining accuracy is high,
Weight is big, manufactures difficulty etc..Increase production, save, putting forward effect.
Utility model content
Goal of the invention of the present utility model is：For above-mentioned problem, there is provided a kind of large-diameter mechanical seal dress
Put.
The technical solution adopted in the utility model is such：
A kind of large-diameter mechanically-sealing apparatus, including the axle sleeve being socketed on axle and the gland, close being socketed on axle sleeve
Seat, interior stationary ring, interior rotating ring, outer rotating ring and outer stationary ring are sealed, the axle sleeve right-hand member and interior rotating seat are integrally manufactured, dynamic inside on axle sleeve
Interior rotating ring and interior stationary ring are socketed between ring seat and seal receptacle, the gland left end and outer stationary seat are integrally manufactured, on axle sleeve
Outer stationary ring and outer rotating ring are socketed between outer stationary seat and seal receptacle, the gland left end passes through the locating piece and screw on axle sleeve
Axial restraint, gland right-hand member are connected by soket head cap screw with seal receptacle, and outer stationary ring is resisted against on outer stationary seat, outer rotating ring against
On the spring base being socketed on axle sleeve, the spring base is by the limited step axial restraint on axle sleeve and passes through key and axle sleeve
Between circumferentially fixed, hold-down ring one of the axle sleeve left end socket with flange, hold-down ring two is socketed on hold-down ring one and two
Person's contact surface is taper, and the flange of hold-down ring one is connected with hold-down ring two by hex bolts.
Preferably, also by being driven pin connection between the outer rotating ring and spring base.
Preferably, the studs and hex nut axially in parallel with axle sleeve are provided with the seal receptacle, for inciting somebody to action
Whole seal receptacle is connected with high-capacity pump housing.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：
1st, key connection is used between outer rotating ring and axle sleeve, using transmission pin connection between outer rotating ring and spring base, so as to real
Existing Dual positioning connection, reduces axial direction, the play of radial direction, ensures the reliability service of transmission.
2nd, the interior integral structure of rotating seat and axle sleeve, size, Form and position error caused by reducing parts processing, avoids dress
With error.So as to ensure high-precision cooperation, increase reliability of operation.
3rd, seal receptacle and gland use Split type structure, and convenient disassembly is cost-saved.
4th, by the way of taper holding, conventional screw transmission, clamping ring transmission is changed, reduces component number
Amount, thrust is stronger, so as to effectively avoid axle sleeve from skidding, adds the reliability of transmission.
