Abstract
The utility model relates to a centrifugal fan of an air conditioner for a train. The centrifugal fan comprises an installation base plate, volute casings, a double-extending-shaft motor, an air inlet current collector and wind wheels; each volute casing is defined by a front side plate, a rear side plate and an enclosing plate; air inlets are arranged on the front side plates; motor shaft feed-through openings are arranged on the rear side plate; and the outer edges of the front and the rear side plates which are arranged oppositely are connected with the folded edges of the enclosing plate through rivets. The centrifugal fan is low in processing cost and light in weight; and under the condition of rated wind volume, not only is the wind pressure higher, but also the noise produced by the centrifugal fan of the air conditioner is reduced, and the sound quality of the centrifugal fan of the air conditioner is improved.
Description
Technical field
The utility model relates to the train supply air system, is specifically related to a kind of centrifugal blower that is used for train air-conditioning.
Background technique
According to national strategy for urban development, improve the urban transportation severe situation and accomplish energy-conserving and environment-protective, expand city and inter-city rail transit energetically.
Not only to further improve fan delivery and reduce performance such as noise the train air-conditioning centrifugal blower, also will solve weight issue, satisfy the fire prevention of unit, requirement such as anticorrosion and anticreep again.At present traditional train air-conditioning centrifugal blower main body is main with carbon steel or stainless steel, and blower fan weight is big, and particularly the ability of maintenance of carbon steel is poor, can not be applicable to that new air-conditioning unit reaches the requirement of energy-conservation purpose to alleviate unit weight.In order to alleviate the blower fan quality, can adopt material such as aluminium to replace traditional carbon steel or stainless steel, but the processing technology of aluminium blower fan is complicated, cost is high.
The model utility content
The purpose of the utility model is to overcome shortcoming of the prior art with not enough, and a kind of in light weight, noise is little, air quantity is big, processing cost is low train air-conditioning centrifugal blower is provided.
The utility model is to realize through following technological scheme: a kind of train air-conditioning centrifugal blower; Comprise base plate, spiral case, double extension shaft motor and wind wheel are installed; Described spiral case is surrounded by front side plate, back side panel and coaming plate and forms; Said front side plate is provided with suction port, and said back side panel is provided with the motor shaft openings, and the said forward and backward biside plate that is oppositely arranged is connected through rivet with said coaming plate.
The outer edge of said forward and backward biside plate is connected through rivet with the flanging of said coaming plate.
Described suction port is equipped with the air inlet slip ring, and described air inlet slip ring diameter range is 170mm-210mm.
Said wind wheel is formed by two axial continued accesses of single-wheel, and the blade of said two single-wheels staggers each other, and described blade is the veneer arc shaped blade, and described rotor diameter scope is 200mm-260mm.
Said installation base plate, spiral case, double extension shaft motor and wind wheel all adopt aluminium material.
With respect to existing technology, the utility model is simple in structure, and spiral case is connected through rivet with the flanging of coaming plate by the outer edge of the forward and backward side plate that is oppositely arranged; Effectively reduce processing cost, the suction port of front side plate also is equipped with the air inlet slip ring, can reduce flow perturbation; Reduce the noise that the air-conditioning centrifugal blower sends, improve the sound quality of air-conditioning centrifugal blower, body all adopts aluminium material not only to alleviate the weight of unit; Save the train power consumption, can also make gas stream when impeller, produce more high pressure.
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.

Embodiment
Like Fig. 1 to a kind of train air-conditioning centrifugal blower of the utility model shown in Figure 4; Comprise base plate 10, spiral case 20, double extension shaft motor 30, air inlet slip ring 24, wind wheel 40, link 43, reel 44 are installed; Double extension shaft motor 30 and two spiral cases 20 are fixedly mounted on through socket head screw and install on the base plate 10, and two wind wheels 40 are fixed on spiral case 20 inside at motor double extension shaft two ends.
This installation base plate 10, spiral case 20, double extension shaft motor 30, air inlet slip ring 24, wind wheel 40 all adopt aluminium to be made, and not only alleviate the complete machine quality, have also improved fire prevention, anti-corrosion function.
When centrifugal blower is worked, be fixed on the double extension shaft motor of installing on the base plate 10 30 and start, drive wind wheel 40 work in the two ends spiral case 20; When gas when intake grill is flowed through impeller through air inlet slip ring 24; Not only reduce flow perturbation, and under the effect of two single-wheels 41, be equivalent to secondary diffusion; The wind of discharging from exhaust outlet produces more high pressure, thereby reduces noise when improving fan delivery.
The utility model is not limited to above-mentioned mode of execution; If the various changes of the utility model or distortion are not broken away from the spirit and the scope of the utility model; If these changes and distortion belong within the claim and equivalent technologies scope of the utility model, then the utility model also is intended to comprise these changes and distortion.
