Abstract
The utility model discloses a disconnect -type helical -lobe compressor contains compressor sealed shell, electric motor rotor and motor stator, the sealed shell of compressor is sealed protection casing, and electric motor rotor rotates and sets up inside the sealed shell of compressor, and motor stator sets up in the sealed shell outside of compressor. Disconnect -type helical -lobe compressor is directed against the refrigerating system condition, and with the rotor and the stator separation of motor, the stator setting that will generate heat is in the casing outside to in having avoided bringing the stator heat into refrigerating system, improve refrigerating system's refrigeration effect, convenience is more maintained in the casing outside to stator setting simultaneously.
Description
Technical field
This utility model relates to a kind of compressor, particularly a kind of separation-type screw compressor.
Background technology
Helical-lobe compressor is divided into single screw compressor and double-screw compressor, is proposed in 1878 by German H.Krigar the earliest, until KTH of Sweden A.Lysholm in 1934 just establishes this technology, and starts industrially to apply, obtains rapid development.Helical-lobe compressor, also referred to as screw compressor, including screw air compressor and screw rod technique compressor (vinyl chloride compressor etc.), screw machine is positive displacement twin screw injected compressor, the most box skid structure.
Helical-lobe compressor is currently mainly divided into external motor to drive, semi-enclosed helical-lobe compressor and totally enclosed type helical-lobe compressor, and totally enclosed type helical-lobe compressor cost is relatively low and simple in construction, more and more extensive in the application of refrigeration system at present.But in ammonia refrigeration system, the stator of the motor of totally enclosed type helical-lobe compressor and rotor are all enclosed in seal casinghousing, stator contacts with the liquefied ammonia of ammonia refrigeration with rotor, although so motor can be cooled down with liquefied ammonia, but also motor heat is brought into refrigeration system, reduced the effect of refrigeration.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of separation-type screw compressor, and rotor is separated with stator, thus avoids bringing in refrigeration system stator heat into by it.
For solving above-mentioned technical problem, this utility model be the technical scheme is that
A kind of separation-type screw compressor; comprise compressor seal shell, rotor and motor stator; it is characterized in that: described compressor seal shell is the protective housing sealed, rotor rotates and is arranged on inside compressor seal shell, and motor stator is arranged on outside compressor seal shell.
Further, being provided with protecting of stator shell outside described motor stator, protecting of stator shell is fixed on compressor seal shell-side face.
Further, described motor stator comprises stator winding, stator core and support, and stator winding is around being located on stator core, and stator core is fixed on support, and support is set in outside compressor seal shell and is fixed on compressor seal shell.
Further, it is provided with chiller in described protecting of stator shell.
Further, described chiller is cooling fan, and fan is arranged on containment vessel side, and containment vessel side has louvre.
Further, described chiller is oil cooling device, and protecting of stator shell seals and is fixed on compressor seal shell and has the oil-in being connected with oil cooling device and oil-out on protecting of stator shell.
Further, the material that described compressor seal shell uses thermal insulation good is made.
Further, described compressor seal shell uses high-strength material to make.
Further, it is 1 ~ 2mm with compressor seal shell gap outside described rotor.
This utility model is compared with prior art, have the following advantages and effect: separation-type screw compressor is for refrigeration system situation, the rotor of motor is separated with stator, the stator of heating is arranged on hull outside, thus avoid and stator heat is brought in refrigeration system, improve the refrigeration of refrigeration system；Stator is arranged on hull outside simultaneously, keeps in repair enhanced convenience.
