        通風管道在工作中產生的噪音應如何控制

        來源:http://www.boursomarket.com 日期:2021-02-20 發布人:gaoshitongferng

        螺旋風管在運轉過程會發生必定的噪音,假如在住宅區和商業區會對人們的生活發生很大的影響。那么我們在施工過程中如何削減噪音呢?
        Spiral duct in the operation process will produce certain noise, if 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?
        濟南通風管道體系運轉噪音通常來源于以下幾個方面:
        The running noise of Jinan ventilation pipe system usually comes from the following aspects:
        風管的震動。因為風管資料是鍍鋅板或者是金屬資料,在施工時要嚴厲按照施工驗收標準選擇鋼板厚度和施工工藝,比如風管制造偏差、平直度、風管加固、支吊架選擇及制造裝置等等。到了施工階段,出風口盡量不要靠近設備。風扇前后盡量都有5米以上的長度。假如可以添加彎頭數目也可以下降噪音,風口加裝過濾網,噪音操控效果也很好。
        The vibration of the duct. Because the air duct information is galvanized sheet or metal information, the steel plate thickness and construction technology should be strictly selected according to the construction acceptance standard, such as the air duct manufacturing deviation, straightness, air duct reinforcement, support selection and manufacturing device, etc. At the construction stage, the air outlet should not be close to the equipment as far as possible. The front and back of the fan should be more than 5 meters long. If the number of elbows can be added, the noise can also be reduced. If the air outlet is equipped with a filter, the noise control effect is also very good.

        風機的聲響。處理辦法我們通常可裝消聲器處理
        The sound of the fan. We can usually install a muffler
        風管中風的沖突聲。通常在設計階段就要思考噪聲的問題,設計操控好管內風速,防止風聲嘯叫,以下是一些經歷。
        The clash of wind in the duct. Usually in the design stage, we need to consider the problem of noise, design and control the wind speed in the pipe to prevent the wind from whistling. Here are some experiences.
        1、操控出風、回風間隔,防止空氣對流時自激表象和小循環空間。
        1. Control the air outlet and return air interval to prevent the self-excited appearance and small circulation space during air convection.
        2、螺旋風管風機葉輪體系動平衡校調合理正常正負不大于5絲的起伏。
        2. The dynamic balance adjustment of spiral duct fan impeller system is reasonable, and the fluctuation of positive and negative is no more than 5 threads.
        3、軟接頭裝置標準,防止軟接帆布松垮發生風阻而形成風噪。
        3. The standard of flexible joint device can prevent wind resistance and wind noise caused by loose canvas.
        4、懸掛選用順便彈簧避震專職的連接器,減輕運轉時因扭力發生的跳動或共頻。
        4. The suspension adopts the spring shock absorber connector to reduce the runout or common frequency caused by torsion during operation.

        5、螺旋風管風道轉角盡量削減
        5. The angle of spiral duct should be reduced as much as possible
        山東通風管道風管轉角縫或閉合縫有三種銜接辦法:焊按、鉚接和咬口銜接。因咬口銜接工藝具有強度高、嚴密性好、咬口縫接連均勻、不破壞板材表面質量、外形漂亮、易于完成機械化加工等突出特點而獲得廣泛應用,南京通風管道。
        There are three ways to connect the corner seam or closing seam of Shandong ventilation pipeline: welding, riveting and biting. Because of the outstanding characteristics of high strength, good tightness, even joint, no damage to the surface quality of the plate, beautiful appearance, easy to complete mechanized processing, the biting joint technology has been widely used.
        常見的轉角縫咬口方式為聯合角咬口、按扣式咬口和轉角咬口,常見的閉合縫咬口方式為單平咬口和單立咬口。
        The common corner seam bite modes are combined corner bite, button bite and corner bite, and the common closed seam bite modes are single flat bite and single vertical bite.
