Description
Technical field
The utility model relates to carbon ring seal technical field, double isolation carbon of specially a kind of magnetic suspension vapor compressor
Ring sealing 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 leaked often contains corrosive substance, therefore once leaks 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.
