大型建筑,為了達(dá)到良好的通風(fēng)效果,通常采取通風(fēng)措施,除了空調(diào)電力設(shè)備,往往添加一些通風(fēng)管道,達(dá)到通風(fēng)換氣的功能,以及實(shí)現(xiàn)這一目標(biāo),我們正在通過螺旋風(fēng)管、螺旋風(fēng)管廣泛應(yīng)用。今天和我們談?wù)劃?jì)南風(fēng)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(fēng)管有很多,但它是在大多數(shù)情況下暴露在戶外,所以風(fēng)下雨,太陽(yáng),這些因素將螺旋風(fēng)管侵蝕或腐蝕,因此要求它具有防腐性能的產(chǎn)品有鍍鋅螺旋風(fēng)管、不銹鋼螺旋風(fēng)管、復(fù)合螺旋風(fēng)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(fēng)管氣流良好，有效流動(dòng)面積大，系統(tǒng)壓降小，日常運(yùn)行系統(tǒng)功耗低。同時(shí)，由于螺旋風(fēng)管采用螺旋咬口，其強(qiáng)度高于相同規(guī)格的風(fēng)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(shè)有螺旋咬口縫，增加了空氣管道的強(qiáng)度，不易產(chǎn)生振動(dòng)。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(zhì)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(fēng)道截面相似、風(fēng)道材料厚度相同的前提下，橢圓螺旋風(fēng)道在低頻段的隔聲效果比矩形風(fēng)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(fēng)管機(jī)械化程度高
High degree of mechanization of spiral duct
螺旋橢圓形風(fēng)管與帶鋼卷螺旋風(fēng)管,通過風(fēng)管成型機(jī)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(shí),咬縫的壓力,后使用特殊設(shè)備將拉伸后的圓形風(fēng)管成型加工成一個(gè)扁平的橢圓。用戶可根據(jù)需要剪短。螺旋風(fēng)管的制造自動(dòng)化程度高，生產(chǎn)速度快。同時(shí)采用工廠化生產(chǎn)和標(biāo)準(zhǔn)化生產(chǎn)，大大提高了橢圓螺旋風(fēng)管的生產(chǎn)效率，整體性強(qiáng)。
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.
