大型建筑,為了達到良好的通風效果,通常采取通風措施,除了空調電力設備,往往添加一些通風管道,達到通風換氣的功能,以及實現這一目標,我們正在通過螺旋風管、螺旋風管廣泛應用。今天和我們談談濟南風管加工廠:
In order to achieve good ventilation effect in large-scale buildings, ventilation measures are usually adopted. In addition to air-conditioning power equipment, some ventilation ducts are often added to achieve ventilation and ventilation function, and to achieve this goal, we are using spiral ducts and spiral ducts widely. Today we talk about Jinan Air Pipe Processing Plant:
盡管螺旋風管有很多,但它是在大多數情況下暴露在戶外,所以風下雨,太陽,這些因素將螺旋風管侵蝕或腐蝕,因此要求它具有防腐性能的產品有鍍鋅螺旋風管、不銹鋼螺旋風管、復合螺旋風管,三種管道耐腐蝕。
Although spiral duct has many advantages, it is exposed to the outdoors in most cases, so wind, rain, sun, these factors will corrode or corrode the spiral duct. Therefore, the products required for its anti-corrosion performance are galvanized spiral duct, stainless steel spiral duct, composite spiral duct, and three kinds of pipelines are corrosion-resistant.
螺旋風管氣流良好，有效流動面積大，系統壓降小，日常運行系統功耗低。同時，由于螺旋風管采用螺旋咬口，其強度高于相同規格的風管。
The helical duct has good air flow, large effective flow area, small pressure drop and low power consumption in daily operation. At the same time, the strength of the spiral duct is higher than that of the duct of the same specification because of the spiral bite.
在空氣通過管道的過程中，圓周處設有螺旋咬口縫，增加了空氣管道的強度，不易產生振動。因此，它在降低低頻噪聲的傳播方面具有良好的隔聲效果，可以有效地降低管壁的傳聲，提高建筑的質量。研究表明，由于螺旋管的剛度比螺旋管高，其下頻段為3~10dB，下頻段為12~ 20db。在風道截面相似、風道材料厚度相同的前提下，橢圓螺旋風道在低頻段的隔聲效果比矩形風道好約10dB。
In the process of air passing through the pipeline, there are spiral bite seams at the circumference, which increase the strength of the air pipeline and avoid vibration. Therefore, it has good sound insulation effect in reducing the transmission of low-frequency noise, can effectively reduce the sound transmission of the pipe wall, and improve the quality of the building. The results show that the stiffness of the helical tube is higher than that of the helical tube, and its lower frequency band is 3-10 dB and 12-20 db. On the premise of similar cross section and the same thickness of duct material, the sound insulation effect of elliptical helical duct in low frequency band is about 10 dB better than that of rectangular duct.
螺旋風管機械化程度高

螺旋橢圓形風管與帶鋼卷螺旋風管,通過風管成型機咬骨頭的形狀,以及沿螺旋漸開線跟蹤卷成圓管的形狀,與此同時,咬縫的壓力,后使用特殊設備將拉伸后的圓形風管成型加工成一個扁平的橢圓。用戶可根據需要剪短。螺旋風管的制造自動化程度高，生產速度快。同時采用工廠化生產和標準化生產，大大提高了橢圓螺旋風管的生產效率，整體性強。
The spiral elliptical duct and the strip coiled spiral duct are formed into a flat ellipse by means of the shape of the bite bone of the duct forming machine and the shape of the coiled circular duct tracked along the spiral involute. At the same time, the pressure of the bite seam is used to shape the stretched circular duct. Users can cut it short as needed. The manufacturing automation of spiral air duct is high and the production speed is fast. At the same time, the production efficiency of elliptical helical duct has been greatly improved by adopting factory production and standardized production.
