伴隨著制造行業(yè)的發(fā)展趨勢(shì)，螺旋風(fēng)管機(jī)制造行業(yè)正朝著改進(jìn)模具設(shè)備、生產(chǎn)工藝流程和設(shè)計(jì)產(chǎn)品的方位發(fā)展趨勢(shì)，在我國(guó)螺旋風(fēng)管機(jī)的技術(shù)性能或許越來(lái)越好。隨著技術(shù)的發(fā)展，人們對(duì)通風(fēng)空調(diào)工程的質(zhì)量要求相對(duì)提高，現(xiàn)有的螺旋風(fēng)管和螺旋圓風(fēng)管應(yīng)用廣泛，考慮了通風(fēng)空調(diào)工程和除灰運(yùn)輸?shù)墓δ芤蟆?br /> With the development trend of the manufacturing industry, the spiral air duct machine manufacturing industry is developing towards the direction of improving mold equipment, production process and design products. The technical performance of spiral air duct machines in China may be getting better and better. With the development of technology, people's requirements for the quality of ventilation and air conditioning projects are relatively improved. The existing spiral air ducts and spiral round air ducts are widely used, taking into account the functional requirements of ventilation and air conditioning projects and ash removal transportation.
這就規(guī)定在當(dāng)今的技術(shù)性上開(kāi)展可持續(xù)發(fā)展，挑選更節(jié)省原材料，身心健康可持續(xù)發(fā)展的對(duì)策，進(jìn)行機(jī)器設(shè)備的開(kāi)發(fā)設(shè)計(jì)、生產(chǎn)制造。目前，圓形風(fēng)管和螺旋風(fēng)管是空調(diào)通風(fēng)管道中使用金屬風(fēng)管的關(guān)鍵。圓管壓縮強(qiáng)度大，耗材少，但制造工藝復(fù)雜，占室內(nèi)空間大；螺旋風(fēng)管布局便捷，生產(chǎn)加工便捷，因此運(yùn)用較為廣泛。以及由鋼鏈螺旋線圈電感制成的圓形和矩形框架的機(jī)械自動(dòng)化生產(chǎn)。為了節(jié)省室內(nèi)空間，許多螺旋風(fēng)管都是扁圓形的。
This stipulates that we should carry out sustainable development in today's technology, select countermeasures that save raw materials and keep our physical and mental health sustainable, and carry out the development, design, production and manufacturing of machinery and equipment. At present, circular air duct and spiral air duct are the key to use metal air duct in central air conditioning ventilation duct. The circular tube has high compression strength and few consumables, but its manufacturing process is complex and takes up large indoor space; The spiral air duct is widely used because of its convenient layout and convenient production and processing. And mechanical automatic production of circular and rectangular frames made of steel chain spiral coil inductors. In order to save indoor space, many spiral air ducts are oblate.

在自然通風(fēng)空調(diào)系統(tǒng)工程中，氣體流動(dòng)性的摩擦阻力分成2類：一類是由于氣體自身的粘稠度和與壁厚的摩擦力而導(dǎo)致的壓力損失，即沿途的摩擦阻力損失；另一類是由于氣體流過(guò)某種管路時(shí)，勻稱流動(dòng)性損壞，造成水流量尺寸和方位轉(zhuǎn)變，渦旋造成的動(dòng)能損失，即部分摩擦阻力損失。各種風(fēng)管方式各有優(yōu)缺點(diǎn)，可供應(yīng)用的地方，對(duì)其使用地點(diǎn)，都明確提出了圓弧風(fēng)管的定義。圓弧風(fēng)管來(lái)自對(duì)螺旋風(fēng)管和圓形風(fēng)管的控制改善。擺脫圓形風(fēng)管要求的大室內(nèi)空間高寬比規(guī)定螺旋風(fēng)管耗費(fèi)原材料，螺旋風(fēng)管流體功率缺點(diǎn)，大幅度運(yùn)用截面受限室內(nèi)空間，節(jié)省原材料耗費(fèi)，降低塵土堆積，便于清理。
In the natural ventilation and air conditioning system engineering, the friction resistance of gas fluidity is divided into two categories: one is the pressure loss caused by the viscosity of the gas itself and the friction with the wall thickness, that is, the friction resistance loss along the way; The other is the kinetic energy loss caused by vortex, that is, partial friction resistance loss, due to the change of water flow size and orientation due to the damage of symmetrical fluidity when the gas flows through a certain pipeline. Each air duct mode has its own advantages and disadvantages. The definition of arc air duct is clearly put forward for the places where it can be supplied and used. Arc duct comes from the control improvement of spiral duct and round duct. Get rid of the shortcomings of spiral air duct in terms of height width ratio of large indoor space required by circular air duct, such as raw material consumption, fluid power of spiral air duct, and large scale use of confined indoor space of section to save raw material consumption, reduce dust accumulation, and facilitate cleaning.
