Abstract
A kind of import high negative pressure turbine composite seal device is made of housing, hexagon socket cap head screw, oil scraper ring, graphite grazing axle sleeve, graphite annulus, main shaft, graphite grazing body, stage teeth sealing axle sleeve, stage teeth sealing；It is characterized in that stage teeth sealing axle sleeve, graphite grazing axle sleeve are placed on main shaft successively；Graphite grazing body, stage teeth sealing are by seam allowance location and installation on housing；Graphite grazing body and graphite grazing axle sleeve are provided with 5 graphite annulus；Oil scraper ring is mounted on by hexagon socket cap head screw on graphite grazing body.The utility model is a kind of good seal performance, low cost, the import high negative pressure turbine composite seal device of service life length.
Description
Technical field
The utility model is related to paper industry, metal smelt, chemical fields.For conveying air and other particularity gases
Import high negative pressure turbine composite seal device.
Background technology
Traditional multistage centrifugal turbomachine, inlet pressure are mostly negative pressure.When negative pressure is higher, because of turbine inner port
Pressure is far below the atmospheric pressure outside turbine.Pressure difference value is bigger, and turbine operationally, get over by external gas or impurity
Inside is easily sucked by turbine, inside lubricating oil sucking turbine, turbine inner sealing is damaged with by bearing housing, also can
Pumped (conveying) medium is caused to be contaminated.Under normal circumstances, system process is very high to the degree of purity requirement of medium.Prevent introduced contaminants
Or gas enter inside turbine very it is necessary to.
Utility model content
The utility model can effectively solve above-mentioned technological deficiency, provide and provide a kind of good seal performance, low cost, using the longevity
Order long import high negative pressure turbine composite seal device.
To achieve the above object, the technical solution adopted in the utility model is a kind of import high negative pressure turbine with compound close
Seal apparatus, be by housing, hexagon socket cap head screw, oil scraper ring, graphite grazing axle sleeve, graphite annulus, main shaft, graphite grazing body,
Stage teeth sealing axle sleeve, stage teeth sealing composition；It is characterized in that stage teeth sealing axle sleeve, graphite grazing axle sleeve are placed on successively
On main shaft；Graphite grazing body, stage teeth sealing are by seam allowance location and installation on housing；In graphite grazing body and graphite grazing axis
Set is provided with 5 graphite annulus；Oil scraper ring is mounted on by hexagon socket cap head screw on graphite grazing body.
Due to the adoption of the above technical scheme, the utility model effectively stops the sucking of lubricating oil and other impurities, to turbine
Graphite grazing and stage teeth sealing inside machine play a protective role, and not only sealing effect is good for the technical solution, but also uses the longevity
It orders longer.
Description of the drawings
Fig. 1 is a kind of import high negative pressure turbine composite seal device structure diagram of the utility model；
Fig. 2 is a kind of import high negative pressure turbine composite seal device structural side view of the utility model；
In figure：1st, housing；2nd, hexagon socket cap head screw；3rd, oil scraper ring；4th, graphite grazing axle sleeve；5th, graphite annulus；6、
Main shaft；7th, graphite grazing body；8th, stage teeth sealing axle sleeve；9th, stage teeth seals.
Specific embodiment
The utility model will be further described below in conjunction with the accompanying drawings, not to the limitation of its protection domain.
A kind of import high negative pressure turbine composite seal device, is by housing（1）, hexagon socket cap head screw（2）, gear
Oil ring（3）, graphite grazing axle sleeve（4）, graphite annulus（5）, main shaft（6）, graphite grazing body（7）, stage teeth sealing axle sleeve（8）, it is high
Low tooth sealing（9）Composition；It is characterized in that by stage teeth sealing axle sleeve（8）, graphite grazing axle sleeve（4）Main shaft is placed on successively（6）
On；Graphite grazing body（7）, stage teeth sealing（9）By seam allowance location and installation in housing（1）On；In graphite grazing body（7）With stone
Black sealing axle sleeve（4）It is provided with 5 graphite annulus（5）；Oil scraper ring（3）Pass through hexagon socket cap head screw（2）It is mounted on stone
Black seal（7）On.When import high negative pressure turbine assembles, the shaft end seal of casing, using graphite grazing, with height it is tooth-like
Labyrinth seal, and equipped with oil scraper ring（3）Composite construction sealing.Graphite grazing axle sleeve（4）, stage teeth sealing axle sleeve（8）Hot jacket
In main shaft（6）On.Graphite grazing body（7）, stage teeth sealing（9）, oil scraper ring（3）Separation structure in above and below being.Justified with interior hexagonal
Chapiter screw（2）By oil scraper ring（3）Lock is in graphite grazing body（7）It goes up and fixes.By graphite grazing body（7）, stage teeth sealing（9）
It is placed in casing（1）Sleeve sealing position.By graphite grazing body（7）, stage teeth sealing（9）Lower half is placed in casing（1）Lower half, stone
Black seal（7）, stage teeth sealing（9）The first half is placed in casing（1）The first half.Graphite annulus（5）It is made of per ring three valve graphite,
It is easily installed, dismantles.Graphite is screwed in into graphite grazing body（7）In seal cavity.Lubricating oil is effectively stopped using the technical solution
With the sucking of other impurities, play a protective role to the graphite grazing inside turbine and stage teeth sealing, not only sealing effect
It is good, and service life is longer.
Therefore, the utility model is the import high negative pressure turbine use of a kind of good seal performance, low cost, service life length
Composite seal device.
