Abstract
The utility model relates to a kind of rotary compressor; comprise compressor housing, be arranged on rotor, motor stator and pump assembly in compressor housing; rotor and motor stator form compressor electric motor assembly; rotor is arranged on motor stator inside; pump assembly is connected to the below of rotor, and the underpart of compressor electric motor assembly is provided with built-in protector.Compared with prior art; the utility model is arranged on protector in the region of motor underpart and compressor pump exhaust upper end portion; protector when receiving fluorine operating mode or coolant leakage can be moved in time, shortened the actuation time of protector, improve the reliability of compressor.
Description
Technical field
The utility model relates to a kind of air condition compressor, especially relates to a kind of rotary compressor.
Background technique
Existing rotary compressor protector is positioned at motor top, is distal to compressor pump, and when coolant leakage and receipts fluorine operating mode, actuation time is long unfavorable to compressor reliability.
Application number is that 201110404109.8 Chinese patent discloses a kind of rotary compressor and assembly method thereof, comprise housing, motor stator, rotor and pump assembly, also comprise some supporting frames, motor stator external diameter is less than housing internal diameter, after being connected with housing, some supporting frames form frame set, motor stator and frame set interference are connected and fixed, rotor is located by clearance gauge and motor stator, and be connected and fixed with pump assembly, pump assembly is connected with housing, this kind of rotary compressor can reduce compressor cost, improve compressor surface application situation, promote startability, but for air-conditioning system, in secondary refrigerant leakage and while receiving fluorine, shortening protector also needs on actuation time further to improve.
Model utility content
The purpose of this utility model is exactly to provide a kind of actuation time that shortens protector in order to overcome the defect of above-mentioned prior art existence, thereby improves the leakage of refrigerant, improves the rotary compressor of the reliability of compressor.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of rotary compressor; comprise compressor housing, be arranged on rotor, motor stator and pump assembly in compressor housing; described rotor and motor stator form compressor electric motor assembly; described rotor is arranged on motor stator inside; described pump assembly is connected to the below of rotor, and the underpart of described compressor electric motor assembly is provided with built-in protector.
Described built-in protector is positioned at the exhaust gas region of pump assembly upper end portion.
The middle part of described compressor housing is provided with wiring terminal, and this wiring terminal is directly connected with the underpart of motor stator.The upper side of described compressor housing arranges outlet pipe.Described pump assembly is welded to connect in compressor housing through flange plate.
Compared with prior art; the utility model is arranged on protector in the region of motor underpart and compressor pump exhaust upper end portion, and protector when receiving fluorine operating mode can be moved in time, has shortened the actuation time of protector; thereby improve the leakage of refrigerant, improve the reliability of compressor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is that compressor housing, 2 is that rotor, 3 is that motor stator, 4 is that pump assembly, 5 is that built-in protector, 6 is that wiring terminal, 7 is that outlet pipe, 8 is flange plate.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
A kind of rotary compressor, its structure as shown in Figure 1, comprise compressor housing 1, be arranged in compressor housing 1 rotor 2, motor stator 3 and pump assembly 4, rotor 2 and motor stator 3 form compressor electric motor assembly, rotor 2 is arranged on motor stator 3 inside, pump assembly 4 is connected to the below of rotor 2, and pump assembly 4 is welded to connect in compressor housing 1 through flange plate 8.Built-in protector 5 is installed in the underpart of compressor electric motor assembly, and this built-in protector 5 is positioned at the exhaust gas region of pump assembly upper end portion.At the middle part of compressor housing 1, be provided with wiring terminal 6, this wiring terminal 6 is directly connected with the underpart of motor stator 3.The upper side of compressor housing 1 arranges outlet pipe 7.The utility model is by being arranged on built-in protector 5 in the region of electric machine assembly underpart and compressor pump exhaust upper end portion; protector when receiving fluorine operating mode can be moved in time; shorten the actuation time of protector, thereby improved the leakage of refrigerant, improved the reliability of compressor.
