The spiral air duct has exquisite reinforcement limiting technology to make the spiral air duct accept strong pressure. The thickness of the submerged joint at the undercut is four times the thickness of the pipe body. The rigidity of the pipe is very large, showing the superiority of firmness. It can accept large pressure load without damage and deformation, and the thickness of the material can be reduced by 15%.

螺旋風(fēng)管

Spiral duct

這大大降低了生產(chǎn)成本。另外，需要告訴我們的是，螺旋風(fēng)管的制造工藝是非常精密的。它一般是用特種鋼制成的，質(zhì)量自然有保證，可以使用幾年。共同作用還能保證長(zhǎng)時(shí)間使用不變形，大大延長(zhǎng)了風(fēng)管的使用壽命，對(duì)我們的生產(chǎn)具有重要的現(xiàn)實(shí)意義。

Which greatly reduces the production cost. In addition, we need to know that the manufacturing process of spiral air duct is very precise. It is generally made of special steel, and the quality is naturally guaranteed. It can be used for several years. The joint action can also ensure long-term use without deformation, greatly extending the service life of the air duct, which has important practical significance for our production.

螺旋風(fēng)管的制造是選用帶鋼帶卷，用風(fēng)管成型機(jī)一次性咬出咬骨形狀，沿螺旋漸開線軌跡滾成圓管狀，并將咬縫壓在一起，后按要求長(zhǎng)度切割而成。自投放市場(chǎng)以來，因其性能優(yōu)異、運(yùn)行成本低，廣泛應(yīng)用于造船、通風(fēng)、空調(diào)、凈化、橋梁除塵、機(jī)場(chǎng)、隧道等建筑行業(yè)。

The spiral air duct is manufactured by selecting the steel strip roll, biting the bone shape with the air duct forming machine at one time, rolling it into a circular tube along the spiral involute track, pressing the biting seam together, and then cutting it according to the required length. Since it was put on the market, because of its excellent performance and low operating cost, it has been widely used in shipbuilding, ventilation, air conditioning, purification, bridge dust removal, airport, tunnel and other construction industries.

送冷風(fēng)和送熱風(fēng)常見的方式是空調(diào)的管道，需要保溫。還可在內(nèi)部粘貼保溫材料，使風(fēng)管具有美觀的螺旋狀外觀，并可避免吊頂，降低工程造價(jià)。螺旋風(fēng)管的制造自動(dòng)化程度高，生產(chǎn)速度非?？?。一般風(fēng)管每分鐘可產(chǎn)生20～40米，是由于其原材料鍍鋅帶鋼價(jià)格低于整體鍍鋅鋼板，其工廠化生產(chǎn)和標(biāo)準(zhǔn)標(biāo)準(zhǔn)化使成本低于矩形風(fēng)管。

The common way to supply cold air and hot air is the pipe of central air conditioner, which needs insulation. Thermal insulation materials can also be pasted inside to make the air duct have a beautiful spiral appearance, avoid the ceiling, and reduce the project cost. The manufacturing automation of spiral air duct is high and the production speed is very fast. The general air duct can produce 20-40m per minute, because the price of its raw material galvanized steel strip is lower than that of the whole galvanized steel plate, and its factory production and standardization make the cost lower than that of the rectangular air duct.

螺旋風(fēng)管選用先進(jìn)技術(shù)設(shè)備后，如果配備與其他工序相對(duì)應(yīng)的加工設(shè)備，各工序空調(diào)風(fēng)管的加工進(jìn)度和質(zhì)量都會(huì)有較大提升，但加工工藝仍為多工序分離加工，仍需大量人力在多臺(tái)設(shè)備上旋轉(zhuǎn)，空調(diào)風(fēng)管的加工規(guī)劃、加工力和質(zhì)量仍停留在較低階段。可喜的是，選用普通板式法蘭連接技術(shù)后，空調(diào)風(fēng)管的加工工序不僅少了，還省去了許多人工操作工序，仍需下料、切角、壓筋、普通板式法蘭成型、咬角縫、組裝等工序。

After the spiral air duct is equipped with advanced technology and equipment, if the processing equipment corresponding to other processes is provided, the processing progress and quality of the air-conditioning air duct in each process will be greatly improved. However, the processing process is still multi process separation processing, which still requires a large number of manpower to rotate on multiple equipment. The processing planning, processing force and quality of the air-conditioning air duct are still at a low stage. It is gratifying that after the common plate flange connection technology is selected, the processing procedures of the air duct of the air conditioner are not only reduced, but also many manual operation procedures are saved, such as blanking, corner cutting, rib pressing, common plate flange forming, corner biting seam and assembly.

接頭為周向，接頭強(qiáng)度遠(yuǎn)高于徑向直接頭，所以在1.5倍工作壓力下能保證接頭處無裂紋，因?yàn)槠湓牧襄冧\帶鋼低于整片鍍鋅鋼板，其工廠化生產(chǎn)和標(biāo)準(zhǔn)標(biāo)準(zhǔn)化使成本低于矩形風(fēng)管;另外，由于其支吊架需求量小，安裝工作量小，所以總成本低。由于矩形風(fēng)管四角易發(fā)生湍流，有用流動(dòng)面積減小，空氣流動(dòng)性好，有用流動(dòng)面積大，產(chǎn)品的二次噪聲因強(qiáng)度大而小。因此，風(fēng)管振動(dòng)引起的低頻噪聲更小，空氣流動(dòng)性能好，系統(tǒng)壓降小，日常運(yùn)行系統(tǒng)耗電少。

The joint is circumferential, and the strength of the joint is much higher than that of the radial direct head. Therefore, it can be ensured that there is no crack at the joint under 1.5 times the working pressure. Because the raw material galvanized steel strip is lower than the whole galvanized steel sheet, its factory production and standardization make the cost lower than that of the rectangular air duct; In addition, the total cost is low due to the small demand for supports and hangers and the small installation workload. As the four corners of the rectangular air duct are prone to turbulence, the useful flow area is reduced, the air fluidity is good, the useful flow area is large, and the secondary noise of the product is small due to the high intensity. Therefore, the low-frequency noise caused by the air duct vibration is smaller, the air flow performance is good, the system pressure drop is small, and the daily operation system consumes less power.
