Abstract
The utility model discloses a centrifugal fan for a train air conditioner, comprising a volute, a motor and an impeller, wherein the volute is provided with an air inlet and an air outlet, the impeller is arranged at the middle of the volute, and the motor is fixed at the middle of the volute via a bearing rod, and coaxially connected and matched with the impeller. Compared with the prior art, the centrifugal fan disclosed by the utility model has the advantages of being compact and reasonable in overall structure, thus ensuring the matching with a high-speed train air conditioner set, and the strength of products; simultaneously, the centrifugal fan meets the flowing optimal principle of airflow, plays roles in improving the airflow and reducing the noise of the airflow, enables the performance of the fan to be more excellent, and has a higher air pressure and a lower noise under a rated air quantity.
Description
Technical field
The utility model relates to a kind of centrifugal blower, belongs to the Fan Equipment technical field, refers in particular to a kind of train air-conditioning and uses centrifugal blower.
Background technique
At present, existing train air-conditioning is made up of galvanized sheet impeller and cold drawing plastic-blasting spiral case and blower fan base plate adapted cast housing motor with the centrifugal blower major part, and is whole heavy, is unfavorable for the overhead unit of train air-conditioning, and more suitable bullet train uses.Because the bullet train air-conditioning all is the overhead unit, not only claimed structure is lightly compact to corresponding air-conditioning draught fan, and requires withstand prolonged to expose to the sun and rain, and can bear bigger vibration and impact.So, guaranteeing under the prerequisite of fan performance, should solve the high-intensity problem of light weight, satisfy the requirements such as fire retardant anticorrosion of unit again.
The model utility content
The purpose of the utility model is to overcome shortcoming of the prior art with not enough, provides a kind of compact structure, in light weight, practical safe and reliable train air-conditioning to use centrifugal blower.
To achieve these goals, the utility model is realized according to following technological scheme:
A kind of train air-conditioning is used centrifugal blower, includes spiral case, motor and impeller, and wherein, spiral case is provided with intake grill and exhaust outlet, and impeller is arranged at spiral case middle part, and motor is fixed in the spiral case middle part and is connected cooperation with impeller is coaxial through supporting rod.
Further, said impeller includes wheel hub, lower end surface, upper-end surface and blade, and wherein, wheel hub and motor are fastenedly connected, and the lower end surface is connected cooperation with wheel hub, and blade is arranged between upper-end surface and the lower end surface.
Further, said spiral case is arranged at strip hole in exhaust outlet housing position, and strip hole and exhaust outlet are vertically opposite.
Further, said spiral case adopts stainless steel material to make, and its exhaust outlet is designed to four limit diffusion formula structures.
The utility model compared with prior art, its beneficial effect is:
The utility model compact overall structure is reasonable; Both guarantee the coupling with bullet train air-conditioning unit, guaranteed the intensity of product again, also met the best principle of air current flow simultaneously; Played and improved air-flow and the effect that reduces pneumatic noise; Make fan performance more superior, under nominal air delivery, have higher blast and lower noise.
In order to understand the utility model more clearly, below accompanying drawings is set forth the embodiment of the utility model.
Description of drawings
Fig. 1 is the perspective view of the utility model.
Fig. 2 is the Facad structure schematic representation of the utility model.
Fig. 3 is the plan structure schematic representation of the utility model.
Embodiment
Shown in Fig. 1 to 3, the said train air-conditioning of the utility model is used centrifugal blower, includes spiral case 1, motor 2 and impeller 3; Wherein, Spiral case 1 is provided with intake grill and exhaust outlet, and impeller 3 is arranged at spiral case 1 middle part, and motor 2 is fixed in spiral case 1 middle part and is connected cooperation with impeller 3 is coaxial through supporting rod 4.
Above-mentioned impeller 3 includes wheel hub, lower end surface, upper-end surface and blade, and wherein, wheel hub and motor 2 are fastenedly connected, and the lower end surface is connected cooperation with wheel hub, and blade is arranged between upper-end surface and the lower end surface.
Above-mentioned spiral case 1 is arranged at strip hole 11 in exhaust outlet housing position, and strip hole 11 is vertically opposite with exhaust outlet, and strip hole 11 can reduce flow perturbation, makes the air-out of air-conditioning centrifuge more uniform and stable.Further, said spiral case 1 adopts stainless steel material to make, and its exhaust outlet is designed to four limit diffusion formula structures.
The utility model is not limited to above-mentioned mode of execution; If spirit and scope that the various changes or the modification of the utility model do not broken away from the utility model; If these are changed and modification belongs within the claim and equivalent technologies scope of the utility model, then the utility model also is intended to comprise these changes and modification.
