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。

This greatly reduces production costs. Additionally, it should be noted that the manufacturing process of spiral air ducts is very precise. It is usually made of special steel, with guaranteed quality and can be used for several years. The joint effect 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 manufacturing of spiral air ducts involves using a steel strip coil, using a duct forming machine to bite out the bite bone shape in one go, rolling it into a circular tube shape along the spiral involute trajectory, pressing the bite seams together, and then cutting it to the required length. Since its launch in the market, it has been widely used in shipbuilding, ventilation, air conditioning, purification, bridge dust removal, airports, tunnels and other construction industries due to its excellent performance and low operating costs.

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)速度非常快。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 through the pipes of central air conditioning, which require insulation. Insulation materials can also be pasted inside to give the air duct a beautiful spiral appearance and avoid suspended ceilings, reducing project costs. The manufacturing automation of spiral air ducts is high, and the production speed is very fast. Generally, air ducts can produce 20-40 meters per minute due to the lower price of galvanized strip steel as its raw material compared to overall galvanized steel plates. Its factory production and standardization result in lower costs than rectangular air ducts.

螺旋風(fēng)管選用技術(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?？上驳氖?，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 selecting advanced technology equipment for spiral air ducts, if equipped with processing equipment corresponding to other processes, the processing progress and quality of air conditioning ducts in each process will be greatly improved. However, the processing technology is still separated from multiple processes and requires a lot of manpower to rotate on multiple devices. The processing planning, processing force, and quality of air conditioning ducts are still at a relatively low stage. Fortunately, with the use of ordinary plate flange connection technology, the processing procedures for air conditioning ducts have not only been reduced, but also many manual operations have been eliminated. There are still processes such as cutting, cutting corners, pressing reinforcement, forming ordinary plate flanges, biting corner seams, 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 joint. Therefore, it can ensure that there are no cracks at the joint under 1.5 times the working pressure, because the raw material of galvanized strip steel is lower than the entire galvanized steel plate. Its factory production and standardization make the cost lower than rectangular air ducts; In addition, due to the small demand for its supports and hangers and the small installation workload, the total cost is low. Due to the susceptibility of turbulence at the four corners of rectangular air ducts, the useful flow area is reduced, the air flow is good, the useful flow area is large, and the secondary noise of the product is reduced due to its high intensity. Therefore, the low-frequency noise caused by duct vibration is smaller, the air flow performance is good, the system pressure drop is small, and the daily operation of the system consumes less power.
