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%.
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.
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.
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.
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.
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.
