Description
Technical field
The utility model belongs to helicopter evaporation circulating cooling systems technology field, relates to a kind of intermediate frequency hermetically sealed compressor that starts offloading functions that has.
Background technique
At present, on helicopter, evaporation circulating cooling system is mainly made up of compressor, medium frequency electric motivation, vaporizer, condenser, evaporation fan, condensation fan, expansion valve etc.Medium frequency electric motivation is by belt transmission, and the work of drive compression machine realizes refrigeration.This drive form mainly contains following deficiency: the bulk that 1) belt transmission takies is large, and rigging position and installation precision are had relatively high expectations; 2) motor adopts independently radiating mode, has increased radiation fan, air channel etc., causes that its volume is large, quality weight; 3) tensioning of belt and operating life have increased the link such as maintenance, replacing.Hermetically sealed compressor can effectively address the above problem simultaneously; but on the current technology,, the inrush current of hermetically sealed compressor is generally 5～7 times of operating current, in airborne products; large inrush current will make Helicopter Electrical Power protection, produces dead electricity danger.
Model utility content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of intermediate frequency hermetically sealed compressor that starts offloading functions that has is provided, and this intermediate frequency hermetically sealed compressor is realized low current and started.
For achieving the above object, the intermediate frequency hermetically sealed compressor with startup offloading functions described in the utility model comprises electric coupler, front head, rear head, cylindrical shell and is arranged at medium frequency electric motivation, Moving plate, transmission sleeve pipe, main shaft, clutch coil and the clutch friction plate in cylindrical shell;
The rear and front end of described cylindrical shell is connected with front head and rear head respectively, in cylindrical shell, be fixed with the quiet dish matching with described Moving plate, Moving plate and quiet dish are socketed on a side of main shaft, clutch friction plate and clutch coil are socketed on the opposite side of main shaft, Moving plate and clutch friction plate are fixed on the side of main shaft, the output shaft of medium frequency electric motivation is connected with clutch coil by transmission sleeve pipe, and electric coupler is fixed on cylindrical shell, and electric coupler is connected with clutch coil.
Described quiet dish is fixed in cylindrical shell by screw.
Between described quiet dish and the side of main shaft, be provided with seal ring.
The utlity model has following beneficial effect:
The intermediate frequency hermetically sealed compressor with startup offloading functions described in the utility model comprises electric coupler, cylindrical shell and be arranged at the medium frequency electric motivation in cylindrical shell, Moving plate, transmission sleeve pipe, main shaft, clutch coil and clutch friction plate, in the time of work, reduce magnitude of voltage while startup, medium frequency electric motivation is rotated by drive sleeve pipe racks dynamic clutch coil, realizing motor no-load starts, after intermediate frequency motor operation is stable, switch on to clutch coil by electric coupler, the mutual adhesive of clutch coil and clutch friction plate, thereby drive main shaft to rotate by medium frequency electric motivation, and then realize low current start, the utility model is under the condition of equal refrigerating capacity, adopt full-enclosed structure, volume and the weight of evaporation circulating cooling system are significantly reduced, realize intermediate frequency hermetically sealed compressor low current starts simultaneously, reduce the impact to airborne power supply.
