螺旋風(fēng)管在作業(yè)進(jìn)程會(huì)發(fā)作必定的噪音，假定在住宅區(qū)和商業(yè)區(qū)會(huì)對人們的日子發(fā)作很大的影響。那么咱們在施工進(jìn)程中怎樣減少噪音呢？

The helical duct will make certain noise in the process of operation, assuming that in residential and commercial areas will have a great impact on people's lives. So how can we reduce the noise in the construction process?

通風(fēng)管道系統(tǒng)作業(yè)噪音一般來源于以下幾個(gè)方面：

The working noise of ventilation duct system generally comes from the following aspects:

風(fēng)管的顫抖。因?yàn)轱L(fēng)管資料是鍍鋅板或者是金屬資料，在施工時(shí)要嚴(yán)峻按照施工查驗(yàn)規(guī)范挑選鋼板厚度和施工工藝，比如風(fēng)管制造差錯(cuò)、平直度、風(fēng)管加固、支吊架挑選及制造設(shè)備等等。到了施工階段，出風(fēng)口盡量不要挨近設(shè)備。電扇前后盡量都有5米以上的長度。假定能夠添加彎頭數(shù)目也能夠下降噪音，風(fēng)口加裝過濾網(wǎng)，噪音控制效果也很好。

The quiver of the wind pipe. Because the air duct information is galvanized sheet or metal material, the thickness of steel plate and construction technology should be selected strictly according to construction inspection criteria, such as air duct fabrication errors, flatness, air duct reinforcement, support and hanger selection and manufacturing equipment, etc. At the construction stage, the outlet should not be close to the equipment as far as possible. The length of the electric fan should be more than 5 meters before and after it. Assuming that the number of elbows can be added, the noise can be reduced, and a filter is installed in the tuyere, the noise control effect is also very good.

風(fēng)機(jī)的動(dòng)靜。處理方法咱們一般可裝消聲器處理

The movement of the fan. Processing methods We can generally install muffler treatment

風(fēng)管zhong風(fēng)的沖突聲。一般在規(guī)劃階段就要考慮噪聲的問題，規(guī)劃控制好管內(nèi)風(fēng)速，防止風(fēng)聲嘯叫。

The clashing sound of wind pipe zhong. In general, the problem of noise should be considered in the planning stage. The wind speed in the pipe should be well controlled to prevent wind noise from screaming.

通風(fēng)管道的優(yōu)勢：

Advantages of ventilation ducts:

1、防火功用好：其時(shí)普遍存在的問題是制品通風(fēng)道焚燒功用和耐火極限未經(jīng)有關(guān)部門檢測，且部分通風(fēng)道資料的焚燒功用、管壁厚度不符合要求。

1. Good fireproofing function: At that time, the common problem was that the burning function and fireproofing limit of ventilation duct of products had not been tested by relevant state departments, and the burning function and wall thickness of some ventilation duct data did not meet the requirements.

2、造價(jià)低：通風(fēng)管道與傳統(tǒng)磚砌通風(fēng)道比，能節(jié)約工程造價(jià)40%左右；

2. Low cost: ventilation duct can save about 40% of project cost compared with traditional brick ventilation duct.

3、輕質(zhì)高強(qiáng)：與傳統(tǒng)磚砌通風(fēng)道比，菱鎂通風(fēng)道自重輕、強(qiáng)度高，能大幅度下降建筑物的承受荷載；

3. Light weight and high strength: Compared with traditional brick ventilation duct, magnesite ventilation duct has light weight and high strength, which can greatly reduce the bearing load of buildings.

4、規(guī)劃活絡(luò)：通風(fēng)管道可根據(jù)預(yù)留洞的大小，隨時(shí)調(diào)整管道的規(guī)范規(guī)范；

4. Planning of flexible network: ventilation pipeline can adjust the specification of pipeline at any time according to the size of reserved holes;

5、規(guī)劃一起：通風(fēng)管道的開口上設(shè)備了煙氣止回閥和防火阻隔門，能夠有用防止串味和串火；

5. Planning together: flue gas check valves and fire barrier doors are equipped on the opening of ventilation pipes, which can effectively prevent cross-smelling and crossfire.

6、施工簡略：添加了室內(nèi)空間，密閉性好、不返煙、不返臭，能大幅度改進(jìn)室內(nèi)環(huán)境。

6. Simple construction: Adding indoor space, good airtightness, no smoke return, no odor return, can greatly improve the indoor environment.
