Description

A kind of double isolation carbon ring sealing structures of magnetic suspension vapor compressor
Technical field
The present invention relates to carbon ring seal technical field, double isolation carbocyclic rings of specially a kind of magnetic suspension vapor compressor are close Seal structure.
Background technique
Totally composition is complex for vapour compression machine, mainly by three compressibility, steam cooling device and lubricating system bases This unit composition.The steam generated in reboiler (evaporator) is by embedded droplet separation device except the part liquid in devaporation Body, then enters back into vapour compression machine or accordingly with vapour point, in technological design can there are not compressed steam by-pass, with It automatically controls and meets the requirement produced to different steam pressures and temperature or repair leeway when preventing compressor from breaking down.
Domestic vapour compression machine mainly applies to the chemical fields such as evaporation, crystallization, tower, drying, the above industry at present The process also restriction by some factors.For example dry aspect, the low temperature waste gas come out after dry, a certain amount of sky is contained in the inside The incoagulable gas such as gas cause the reduction of its recovery value with the factors such as compression ratio itself are compressed.On the other hand, due to coercibility gas The general character of body, vapour compression machine can also use this aspect of solvent recovery, for example methanol, ethyl alcohol etc..
Magnetic suspension vapor compressor uses high-speed permanent magnetic synchronous motor, and both ends use electromagnetic suspension bearing suspension rotor Group is no longer satisfied pressure using common labyrinth seal or carbon ring seal when the intake air temperature of compressor is more than 100 DEG C The zero leakage requirement of contracting machine, and the vapor revealed often contains corrosive substance, therefore once reveals from the shaft end of compressor Vapor enters electromagnetic bearing out, and the electric insulation that will result in magnetic bearing destroys, so as to cause the considerable safety thing of compressor Therefore.
Summary of the invention
The purpose of the present invention is to provide a kind of double isolation carbon ring sealing structures of magnetic suspension vapor compressor, to solve The problems mentioned above in the background art.
To achieve the above object, the invention provides the following technical scheme: a kind of double isolation of magnetic suspension vapor compressor Carbon ring sealing structure, including carbon ring seal body, the carbon ring seal body be mounted on magnetic suspension vapor compressor and main shaft it Between, the carbon ring seal body includes carbocyclic ring seat and carbocyclic ring face, and six groups of graphite annulus, respectively the first graphite are installed on the carbocyclic ring face Ring, the second graphite annulus, third graphite annulus, the 4th graphite annulus, the 5th graphite annulus and the 6th graphite annulus are provided with water on the carbocyclic ring face Steam air inlet, air inlet and mixing gas outlet, the vapor air inlet are mounted on the second graphite annulus, third graphite annulus Between, the air inlet is mounted between the 5th graphite annulus and the 6th graphite annulus, and the mixing gas outlet is mounted on the 4th Between graphite annulus, the 5th graphite annulus, briquetting is also installed on the carbocyclic ring seat.
Preferably, first graphite annulus, the second graphite annulus, third graphite annulus, the 4th graphite annulus, the 5th graphite annulus and Six graphite ring structures are completely the same, including graphite tape and metal tape, and the graphite tape is arranged in parallel with the metal tape, the stone Ink ribbon winding is in the form of annular discs, and the graphite tape outer surface is provided with annular projection.
Preferably, the carbon ring seal body is connect with spindle thread, is equipped with feed channel inside the main shaft.
Preferably, the briquetting is bolted to connection with spindle drum, installs main shaft on the spindle drum.
Compared with prior art, the beneficial effects of the present invention are:
(1) structure of the invention is novel in design, using double isolation carbon ring seal technologies, not only can guarantee that vapor did not leaked, but also can protect Card air is not entered in vapo(u)rization system.
(2) metal tape is conducive to enhance the intensity of graphite annulus in the graphite annulus that uses of the present invention;Annular projection is conducive to increase Friction between strong graphite annulus and main shaft.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention;
Fig. 2 is graphite annulus structural schematic diagram of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of technical solution referring to FIG. 1-2: a kind of double isolation carbocyclic rings of magnetic suspension vapor compressor Sealing structure, including carbon ring seal body, the carbon ring seal body are mounted between magnetic suspension vapor compressor and main shaft, institute Stating carbon ring seal body includes carbocyclic ring seat 1 and carbocyclic ring face 2, and six groups of graphite annulus, respectively the first graphite annulus are installed on the carbocyclic ring face 2 3, the second graphite annulus 4, third graphite annulus 5, the 4th graphite annulus 6, the 5th graphite annulus 7 and the 6th graphite annulus 8, on the carbocyclic ring face 2 It is provided with vapor air inlet 9, air inlet 10 and mixing gas outlet 11, the vapor air inlet 9 are mounted on the second graphite Between ring 4, third graphite annulus 5, the air inlet 10 is mounted between the 5th graphite annulus 7 and the 6th graphite annulus 8, described mixed It closes gas outlet 11 to be mounted between the 4th graphite annulus 6, the 5th graphite annulus 7, briquetting 12 is also installed on the carbocyclic ring seat 1;Carbocyclic ring is close Feng Tiyu main shaft 16 is threadedly coupled, and is equipped with feed channel inside the main shaft 16;Briquetting 12 and spindle drum 17 are solid by bolt 18 It is fixed to connect, main shaft 16 is installed on the spindle drum 17.
