Abstract
The utility model discloses a scroll compressor comprising a compressor shell, a compressor dynamic and static scroll plate, a motor shield, a motor stator, a motor rotor and a motor shaft. The scroll compressor is characterized in that the motor shaft is connected with a main shaft of a compressor rotor; a shielding housing is used for covering the motor rotor to be separated from the motor stator; the shielding housing and the compressor shell are fixed into a whole; the inside of the shielding housing is communicated with the inside of the compressor shell; the motor shield covers the motor stator; and the motor stator is fixed on the inner side wall of the motor shield so that the motor stator encircles the shielding housing. The motor rotor runs in a compressed refrigerant medium, while the stator is not in the refrigerant medium, the motor stator can be cooled by using many methods, such as water cooling, wind cooling or liquid injecting so that a compressor motor can be effectively cooled; and when the compressor motor is burned, a refrigerating system is not polluted, and various refrigerants can be widely applied to the scroll compressor.
Description
Technical field
The utility model belongs to compression mechanism technology for making field, relates to middle-size and small-size industrial and medical ultralow temperature apparatus field, and the testing installation field is a kind of scroll compressor specifically.
Background technique
Hermetic compressor has a variety of, common reciprocating piston type, rotary vane type, rolling-piston-type, three-apexed rotor formula, the eddy type etc. of mainly containing.
Closed-type scroll compressor belongs to positive displacement compressor, and compression member is made up of moving scroll and quiet vortex, owing to there is not reciprocating mechanism; Have only not wearing and tearing of engagement, thus simple in structure, volume is little, in light weight, part is few, noise is low, gas transmission is steady continuously, reliable; Especially cryogenic property is ultra tall and erect; In, during cryogenic applications, high more than 30% on the volumetric efficiency, be the first-selected kind of present refrigeration compressor than traditional piston machine.
But the same with all hermetic compressors, also there are following 3 problems in the closed-type scroll compression:
1, the gas flow of return-air is little under low temperature ultralow temperature application, is not enough to the cooling compressor motor, and because the insulation variation of back pressure low (usually being negative pressure under low temperature ultralow temperature application) compressor coil.
2, under heat pump operating mode application, the common delivery temperature of high temperature modification refrigeration agent all about 160～350 ℃, so can not work under the high temperature by motor coil.
3, when compressor electric motor burns, can pollute refrigeration system, can't use for the refrigeration agent hermetic compressor of inflammable and explosive perishable (copper enameled cable).
Summary of the invention
The utility model provides a kind of scroll compressor to the problems referred to above that existing technology exists, and makes compressor electric motor can access effective cooling, when compressor electric motor burns, can not pollute refrigeration system, can be suitable for various refrigeration agents widely.
The purpose of the utility model realizes through following technological scheme:
A kind of scroll compressor; Comprise: compressor housing, the dynamic and static scroll of compressor, motor outer cover, motor stator, motor rotor, motor shaft; It is characterized in that: said motor shaft is connected with the main shaft of the motor-driven scroll of compression, has a housing that motor rotor is covered with motor stator and separates, and housing and compressor housing are fixed into one; Inner and the compressor connection of housing; Said motor outer cover covers motor stator, and motor stator is fixed on the motor outer cover madial wall, and motor stator is centered around around the housing.
Improvement to technique scheme: an opening is arranged at described motor outer cover top, on the said opening radiation fan is installed, and described motor outer cover lower edge is connected through bolt with the compressor housing outer wall.
Further improvement to technique scheme: said housing and compressor housing are " protruding " font.
Further improvement to technique scheme: said compressor housing one side is provided with intakeport and relief opening, and the bottom in the said compressor housing is a lubricating oil bath.
The utility model compared with prior art has following advantage and good effect:
The utility model adopts motor and compressor integral structure; Because the main shaft of motor rotor and compressor is fixed together; And motor rotor and stator are separated with housing; So motor rotor is in compressed refrigerant medium, to turn round; But motor stator is in refrigerant medium, and stator coils of motor can adopt water-cooled or several different methods cooling such as air-cooled, has solved the cooling problem of the dynamo-electric machine of low temperature ultralow temperature application lower compression and the problem of compressor coil insulation variation.In addition, when compressor electric motor burns, only need to extract motor stator winding out maintenance and get final product, can not cause any pollution, can not reveal refrigeration agent refrigeration system.
Description of drawings
Fig. 1 is the cut-away view of a kind of scroll compressor of the utility model.
Embodiment
Referring to Fig. 1; The embodiment of a kind of scroll compressor of the utility model; Comprise: the dynamic and static scroll of compressor housing 1, compressor 10, motor outer cover 6, motor stator 4, motor rotor 9, motor shaft 8; Said motor shaft 8 is connected with the main shaft of the motor-driven scroll of compression, has a housing 5 that motor rotor 9 is covered with motor stator 4 and separates.Housing 5 is fixed into one with compressor housing 1, and housing 5 is " protruding " font with compressor housing 1.Housing 5 inner and compressor housing 1 internal communication, said motor outer cover 6 covers motor stator 4, and motor stator 4 is fixed on motor outer cover 6 madial walls, and motor stator 4 is centered around around the housing 5.
At the top of motor outer cover 6 opening is arranged, radiation fan 7 is installed on the said opening, described motor outer cover 6 lower edges are connected through bolt with compressor housing 1 outer wall.
In compressor housing one side intakeport 2 and relief opening 3 are set, the bottom in the said compressor housing 1 is a lubricating oil bath 11.
Compressor and motor rotor 9 all are sealed in the pressure housing that is full of by refrigerant medium, and this pressure housing has only static seal.Motor stator 4 coil winding provide rotating magnetic field and drive motor rotor 9; Motor stator 4 and motor rotor 9 are in different spaces; Motor stator 4 is not in refrigerant medium; Therefore, motor stator 4 coils can adopt several different methods such as water-cooled or air-cooled, oil cooling, hydrojet cooling to cool off.In the embodiment shown in fig. 1, motor is cooled off through the circulating air between motor stator 4 and the housing 5 by radiation fan 7.On the other hand, the range of choice of refrigeration agent has also enlarged, and inflammable and explosive type refrigeration agent, can use refrigeration agent, high temperature modification refrigeration agents such as the mordant ammonia of copper cash.
When the motor of compressor burns, only need to extract motor stator 4 windings out maintenance and get final product, can not cause any pollution to refrigeration system, can not reveal refrigeration agent.
The utility model adopts motor and compressor integral structure, and mounting type can divide horizontal and vertical two kinds.
Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Those skilled in the art; In the essential scope of the utility model, the variation of having done, remodeling, interpolation or replacement also should belong to the protection domain of the utility model.
