        你知道如何減少通風管道的噪音嗎

        來源:http://www.boursomarket.com 日期:2021-03-31 發布人:gaoshitongferng

        提起濟南通風管道想必大家都不陌生吧,它其實是確保空氣的流通,但當有大量氣流進入該管道時會產生一些噪音,那如何減少其噪音你知道嗎?是不是不太清楚?接下來,跟隨濟南風管加工廠家一起去下文了解一下吧,希望能幫到大家。
        Jinan ventilation pipe must be familiar to everyone, it is actually to ensure the circulation of air, but when a large number of air flow into the pipe will produce some noise, so how to reduce the noise? Do you know? Is not very clear? Next, follow the Jinan air pipe processing factory to understand it, hope to help you.

        管道加工的不同型號的管道設備在同一的風量、風壓下、機翼型葉片的離心通風設備噪聲小,前向版型葉片的離心通風設備噪聲大。在噪聲控制要求高的場合,應選用低噪聲管道設備。
        Under the same air volume and pressure, the noise of centrifugal ventilation equipment with wing blade is small, while that with forward blade is large. Low noise pipeline equipment should be selected in the situation of high noise control requirements.
        在設計通風系統時,濟南通風管道加工廠建議應盡量減少系統的壓力損失。當通風系統的總量和壓力損失較大時,可將其分為小系統;氣流在管道內的流速不宜過高,以免引起再生噪聲。確定管道內氣流流速應根據不同要求按有關規定選取。
        In the design of ventilation system, Jinan ventilation pipeline processing plant suggests that the pressure loss of the system should be reduced as much as possible. When the total amount and pressure loss of the ventilation system are large, it can be divided into small systems; the velocity of the air flow in the pipeline should not be too high, so as not to cause regeneration noise. The velocity of air flow in the pipe should be selected according to different requirements and relevant regulations.
        管道和配件可拆卸的接口,不得裝設在墻和走道樓板內。支、吊、托架的預埋件或膨脹螺栓,位置應準確、牢固可靠,埋入部分不得油漆,并應支除油污。
        The detachable joints of pipes and fittings shall not be installed in the wall and corridor floor. The position of embedded parts or expansion bolts of supports, hangers and brackets shall be accurate, firm and reliable. The embedded parts shall not be painted and shall be supported for oil removal.
        適當降低通風設備的轉速。通風設備的旋轉噪聲與葉輪圓周速度10次方成比例,渦流噪聲與葉輪圓周速度6次方(或5次方)成比例,故降低轉速可降低噪聲
        Properly reduce the speed of ventilation equipment. The rotating noise of ventilation equipment is proportional to the 10th power of impeller circumferential speed, and the vortex noise is proportional to the 6th power (or 5th power) of impeller circumferential speed, so reducing the rotating speed can reduce the noise
        水平安裝:風管直徑或大邊長小于40mm,間距<=4m;大于或等于400mm,則間距≤3m。垂直安裝:間距<=4m但每根立管的固定件應大于等于2個。
        Horizontal installation: if the diameter or major side length of air duct is less than 40mm, the spacing is less than or equal to 4m; if it is greater than or equal to 400mm, the spacing is less than or equal to 3m. Vertical installation: the spacing is less than or equal to 4m, but the number of fixings for each riser shall be greater than or equal to 2.
        風管的閥類調節部門應安裝在便于操作的部位,閥板應順氣流方向插入,防火閥安裝位置應正確,易熔件應在系統安裝后裝入。各類風口安裝應平整,位置準確。轉運部分應靈活,與風管連接應牢固。柔性短管安裝松緊適當,不得扭曲。
        The valve regulating Department of the air duct shall be installed at the position convenient for operation, the valve plate shall be inserted along the air flow direction, the installation position of the fire damper shall be correct, and the fusible parts shall be installed after the system is installed. The installation of all kinds of air outlets should be smooth and accurate. The transfer part shall be flexible and firmly connected with the air duct. The flexible short pipe shall be installed with proper tightness without distortion.
