螺旋风管具有精湛的限筋技术,使螺旋风管接受强压力。咬口处的淹没缝厚度是管体厚度的四倍。管材刚度很大,表现出坚固性的优越性,能接受大压力载荷而不发生损伤变形,材料厚度可减少15%。

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

这大大降低了生产成本。另外,需要告诉我们的是,螺旋风管的制造工艺是非常精密的。它一般是用特种钢制成的,质量自然有保证,可以使用几年。共同作用还能保证长时间使用不变形,大大延长了风管的使用寿命,对我们的生产具有重要的现实意义。

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

螺旋风管的制造是选用带钢带卷,用风管成型机一次性咬出咬骨形状,沿螺旋渐开线轨迹滚成圆管状,并将咬缝压在一起,后按要求长度切割而成。自投放市场以来,因其性能优异、运行成本低,广泛应用于造船、通风、空调、净化、桥梁除尘、机场、隧道等建筑行业。

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

送冷风和送热风常见的方式是空调的管道,需要保温。还可在内部粘贴保温材料,使风管具有美观的螺旋状外观,并可避免吊顶,降低工程造价。螺旋风管的制造自动化程度高,生产速度非常快。一般风管每分钟可产生20~40米,是由于其原材料镀锌带钢低于整体镀锌钢板,其工厂化生产和标准标准化使成本低于矩形风管。

The common way to supply cold air and hot air is the pipe of central air conditioning, which needs heat preservation. Insulation materials can also be pasted inside, so that the air duct has a beautiful spiral appearance, and the ceiling can be avoided and the project cost can be reduced. The manufacturing automation of spiral air duct is high, and the production speed is very fast. Generally, the air duct can produce 20 ~ 40 meters per minute, because the price of its raw material galvanized steel strip is lower than that of the overall galvanized steel plate, and its industrialized production and standardization make the cost lower than that of rectangular air duct.

螺旋风管选用技术设备后,如果配备与其他工序相对应的加工设备,各工序空调风管的加工进度和质量都会有较大提升,但加工工艺仍为多工序分离加工,仍需大量人力在多台设备上旋转,空调风管的加工规划、加工力和质量仍停留在较低阶段。可喜的是,选用普通板式法兰连接技术后,空调风管的加工工序不仅少了,还省去了许多人工操作工序,仍需下料、切角、压筋、普通板式法兰成型、咬角缝、组装等工序。

After using advanced technology and equipment for spiral air duct, if equipped with processing equipment corresponding to other processes, the processing progress and quality of air-conditioning air duct in each process will be greatly improved, but the processing technology is still multi process separate processing, which still requires a lot of manpower to rotate on multiple equipment, and the processing planning, processing power and quality of air-conditioning air duct are still at a low stage. Fortunately, after using the ordinary plate flange connection technology, the processing procedures of the air-conditioning duct are not only less, but also many manual operations are omitted, including blanking, corner cutting, rib pressing, forming of the ordinary plate flange, corner seaming, assembly and other procedures.

接头为周向,接头强度远高于径向直接头,所以在1.5倍工作压力下能保证接头处无裂纹,因为其原材料镀锌带钢低于整片镀锌钢板,其工厂化生产和标准标准化使成本低于矩形风管;另外,由于其支吊架需求量小,安装工作量小,所以总成本低。由于矩形风管四角易发生湍流,有用流动面积减小,空气流动性好,有用流动面积大,产品的二次噪声因强度大而小。因此,风管振动引起的低频噪声更小,空气流动性能好,系统压降小,日常运行系统耗电少。

The joint is circumferential, and the strength of the joint is much higher than that of the radial direct head, so it can ensure that there is no crack at the joint under 1.5 times the working pressure, because its raw material galvanized steel strip is lower than the whole galvanized steel sheet, and its industrialized production and standardization make the cost lower than that of the rectangular air duct; In addition, due to the small demand for supports and hangers and the small installation workload, the total cost is low. Because 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 its high intensity. Therefore, the low-frequency noise caused by 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.
