螺旋風管在作業進程會發作必定的噪音，假定在住宅區和商業區會對人們的日子發作很大的影響。那么咱們在施工進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?
通風管道系統作業噪音一般來源于以下幾個方面：
The working noise of ventilation duct system generally comes from the following aspects:
風管的顫抖。因為風管資料是鍍鋅板或者是金屬資料，在施工時要嚴峻按照施工查驗規范挑選鋼板厚度和施工工藝，比如風管制造差錯、平直度、風管加固、支吊架挑選及制造設備等等。到了施工階段，出風口盡量不要挨近設備。電扇前后盡量都有5米以上的長度。假定能夠添加彎頭數目也能夠下降噪音，風口加裝過濾網，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.
風機的動靜。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
風管zhong風的沖突聲。一般在規劃階段就要考慮噪聲的問題，規劃控制好管內風速，防止風聲嘯叫。
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.
通風管道的優勢：
Advantages of ventilation ducts:
1、防火功用好：其時普遍存在的問題是制品通風道焚燒功用和耐火極限未經有關部門檢測，且部分通風道資料的焚燒功用、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、造價低：通風管道與傳統磚砌通風道比，能節約工程造價40%左右；
2. Low cost: ventilation duct can save about 40% of project cost compared with traditional brick ventilation duct.
3、輕質高強：與傳統磚砌通風道比，菱鎂通風道自重輕、強度高，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、規劃活絡：通風管道可根據預留洞的大小，隨時調整管道的規范規范；
4. Planning of flexible network: ventilation pipeline can adjust the specification of pipeline at any time according to the size of reserved holes;
5、規劃一起：通風管道的開口上設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：添加了室內空間，密閉性好、不返煙、不返臭，能大幅度改進室內環境。
6. Simple construction: Adding indoor space, good airtightness, no smoke return, no odor return, can greatly improve the indoor environment.
