            1,玻璃钢风管的空气流动性好,有效通流面积大,系统压降小,日常运行系统耗电量少。同时由于玻璃钢风管采用螺旋状咬口,因此相比同等规格的铁皮风管,其强度要高。当空气通过管道进行传递的过程中,由于圆周设有螺旋型咬缝,增加风管的强度,不易产生振动,因此在降低低频噪声传递上,具有良好的隔声效果,能够有效的降低了管壁传声,提高建筑品质。有研究表明,同样采用D200,厚度为26#钢板制作的对缝管与螺旋管,由于螺旋管的刚度高于对缝管,其低频段比后者低3~10dB,中高频段低12~20 dB。在相近风管截面、风管材料厚度相同的前提下,在低频段椭圆玻璃钢风管的隔声量优于矩形风管10dB左右。

            1. FRP duct has good air fluidity, large effective flow area, small system pressure drop and less power consumption in daily operation. At the same time, the strength of FRP duct is higher than that of iron duct of the same specification because of its spiral bite. When the air is transmitted through the pipeline, the spiral seam around the pipe increases the strength of the duct and does not easily cause vibration. Therefore, in reducing the low-frequency noise transmission, it has good sound insulation effect and can effectively reduce the sound transmission on the wall of the pipe and improve the quality of the building. Some studies have shown that the stiffness of the helical tube is higher than that of the helical tube, which is also made of D200 and 26# steel plate, and its low frequency band is 3-10 dB lower than that of the latter, and its middle and high frequency band is 12-20 dB lower than that of the latter. Under the same cross section and thickness of duct material, the sound insulation capacity of elliptical FRP duct in low frequency band is better than that of rectangular duct about 10 dB.

              2, 玻璃钢风管的机械化程度高

              2. High mechanization of FRP ducts

              螺旋椭圆风管螺旋式风管采用带钢带状卷料,通过风管成型机一次咬出咬口骨形,并沿螺旋渐开线轨迹卷成圆形管状,同时将咬口缝压紧,较后采用特殊的设备将圆形风管经撑拉定型加工成扁椭圆形。用户可根据需要的长度切割而成。玻璃钢风管的制造高度自动化,生产速度很快,同时采用工厂化生产和标准化制作,使得椭圆玻璃钢风管的生产效率大大提高,整体性强。

              Spiral elliptical duct spiral duct is made of strip-shaped coils. The bite bone is bitten out at one time by the duct forming machine, and rolled into a circular tube along the spiral involute trajectory. At the same time, the bite seam is compressed. Later, the circular duct is stretched and shaped into a flat ellipse by special equipment. Users can cut it according to the length they need. The manufacture of FRP ducts is highly automated and the production speed is very fast. At the same time, the production efficiency of elliptical FRP ducts is greatly improved by adopting factory production and standardized production.
