Description
Technical field
The utility model is related to a kind of sealing structure, specifically a kind of ceramic pump packing_seal and single end face machinery
Combined sealing sealing structure.
Background technology
Ceramic pump is as a kind of novel centrifugal blades pump, because of its wear resistance with 3 times of metal Pulp pump or more
Can, it is gradually widely applied in a variety of industries, especially application prospect is more wide in ore dressing, smelting industry.But
Ceramic material brittleness is big, and height is required to the maintenance personal of pump, therefore requires not having to tie up as possible in the flow passage part life cycle of pump
Pump is repaiied, but existing axle envelope mode is difficult to meet this requirement, simple packing_seal wastes since it is desired that often step up packing
A large amount of human resources, and packing_seal cannot prevent to reveal, and gradually can not meet requirement of the current user to environmental protection；It is single
Pure mechanical seal aging effects factor is too many, and pump must be all dismantled when replacement mechanical seal, it is easy to ceramics
Impeller failure, it is therefore desirable to research and develop a kind of new sealing structure to match with the long-life of ceramic pump.
Utility model content
The purpose of this utility model is to provide a kind of ceramic pump packing_seal and single mechanical end face seal combined type are close
Seal structure, solve merely with replaced after machinery bad seals when mechanical seal it is difficult and merely with packing_seal when be difficult to prevent
The defect of leakage.The form that the sealing structure is combined using packing_seal and mechanical seal has No leakage, easily replaces, prolong
The service life of long ceramic pump.
The technical solution adopted by the utility model to solve its technical problems is that：A kind of ceramic pump packing_seal with it is single-ended
Face mechanical seal combined seal structure, structure include seal cage, packing, stuffing box, gland, gland bolt, decompression
Lid, axle sleeve and the single mechanical end face seal component being made of mechanical sealing static ring, mechanical sealing linkage ring, rotating seat, trip bolt,
The mechanical sealing static ring covers fixed mounted in decompression, and mechanical sealing linkage ring is fixed by trip bolt in the rotating seat
It is rotated together with axis on axle sleeve, axle sleeve passes through decompression lid endoporus and stuffing box endoporus, and seal cage and packing are installed in stuffing box.
Further, the single mechanical end face seal component by the logical flushing water cooling in the holes A on stuffing box and lubricates,
The holes A are blocked by silk plug after mechanical sealing assembly damage.
Further, the packing is not compressed before single mechanical end face seal component failures, in single mechanical end face seal group
Gland is fastened after part failure by hold-down bolt by compresses packing, and by holes B on stuffing box it is logical rinse water cooling and
Lubricate packing.
The utility model has the beneficial effects that：
The ceramic Pump Shaft Seal technology of the utility model is the working method being combined using packing_seal and mechanical seal, when
Mechanical seal breaks down and fastens gland when failing by hold-down bolt by compress packing, and passes through the holes B on stuffing box
It is logical to rinse water cooling and lubrication packing, ensure ceramic pump normal operation, without dismantling mechanical seal.The nothing of existing mechanical seal is let out
Advantage is leaked, and has the characteristics that the readily replaceable of packing_seal, ensure that and do not have to because axle envelope is asked in the life cycle of ceramic pump
It inscribes and tears pump open, meet the requirement of ceramic pump complete machine long-life.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
In figure：
1- seal cages, 2- packings, 3- stuffing boxes, 4- glands, 5- gland bolts, 6- decompressions lid, 7- axle sleeves, 8- machinery
Stationary seal ring, 9- mechanical sealing linkage rings, 10- rotating seats, 11- trip bolts, the holes A, the holes B.
Specific implementation mode
A kind of ceramic pump packing_seal of the utility model is combined with single mechanical end face seal with reference to Figure of description
Formula sealing structure is described in detail below.
As shown in Figure 1, a kind of ceramic pump packing_seal of the utility model and single mechanical end face seal combined labyrinth and carbon gland
Structure, it include 1 seal cage, 2 packings, 3 stuffing boxes, 4 glands, 5 gland bolts, 6 decompression lid, 7 axle sleeves and by 8 machinery it is close
Seal the single mechanical end face seal component composition of stationary ring, 9 mechanical sealing linkage rings, 10 rotating seats, 11 trip bolts composition.
8 mechanical sealing static ring covers fixed mounted in 6 decompressions, and 9 mechanical sealing linkage rings lead in 10 rotating seats
It crosses 11 trip bolts and is fixed on 7 axle sleeves and rotated together with axis, 7 axle sleeves pass through 6 decompression lid endoporus and 3 stuffing box endoporus, 3 fillers
1 seal cage of installation and 2 packings in case.
The mechanical sealing assembly is by the logical flushing water cooling in the holes A and lubricates, and is damaged in single mechanical end face seal component
The holes A are blocked by silk plug afterwards.
2 packings are not compressed before single mechanical end face seal component failures, in single mechanical end face seal component failures
Afterwards by 5 hold-down bolts fastening 4 gland by compress 2 packings, and by the holes B lead to flushing water by 1 seal cage enter 2 packings
With the contact surfaces of 7 axle sleeves is cooling and 2 packings of lubrication, while being depressurized from the material refunds 6 of 6 decompression lids and 7 axle sleeve clearance leakages
In lid cavity；Without dismounting after mechanical sealing assembly failure, remedied by packing_seal, the mechanical seal of failure can after
Maintenance is dismantled when phase equipment is safeguarded again, greatly increases working efficiency.
The ceramic Pump Shaft Seal technology of the utility model is the working method being combined using packing_seal and mechanical seal, when
Mechanical seal breaks down and fastens gland when failing by hold-down bolt by compress packing, and passes through the holes B on stuffing box
It is logical to rinse water cooling and lubrication packing, ensure ceramic pump normal operation, without dismantling mechanical seal.The nothing of existing mechanical seal is let out
Advantage is leaked, and has the characteristics that the readily replaceable of packing_seal, ensure that and do not have to because axle envelope is asked in the life cycle of ceramic pump
It inscribes and tears pump open, meet the requirement of ceramic pump complete machine long-life.
The above, some principles of the utility model that only explains through diagrams, this specification are not intended to this practicality
It is novel to be confined in the shown concrete structure and the scope of application, thus it is every be possible to be utilized corresponding change and wait
Jljl belongs to the apllied the scope of the claims of the utility model.
In addition to technical characteristic described in specification, remaining technical characteristic is technology known to those skilled in the art.
