The spiral ductwork machine is specifically designed for the production of spiral ducts—also known as spiral seam thin-walled ducts. The origin of spiral duct technology can be traced back to the military industries of Western countries, where it was initially used in ventilation systems for warships and marine vessels. With broader adoption, spiral ducts gradually found their way into civilian applications such as trains, subways, and mining operations. By the year 2000, usage in the U.S. had surged, with spiral ducts being employed in 95.6% of office buildings, shopping malls, and subway systems. In residential buildings, central air conditioning systems using spiral ducts reached a 72.5% adoption rate. Advantages of the Spiral Ductwork Machine The spiral ductwork machine offers flexible processing of various duct sizes within a defined diameter range—without the need for traditional pipe molds. By adjusting the length of steel coils and making proper setup calibrations, steel strips can be used in place of molds for efficient duct formation. The machine also comes equipped with a high-speed synchronized cutting system that ensures precise cuts according to required duct lengths. Spiral ducts, made from coiled metal strips, feature a spiral seam and thin-walled design with a circular cross-section. These ducts have no welding seams, offer excellent airtightness, and are ideal for both air delivery and bulk material conveyance. As a result, they are becoming the preferred alternative to conventional rectangular ducts. BLKMA's spiral ductwork machine is manufactured to high standards, delivering high output, consistent duct diameters, and superior seam and sealing performance. It can process ducts up to 1.5 meters in diameter and ensures high strength and excellent airtightness. The machine allows for rapid transitions between different duct diameters and includes a high-speed synchronized cutting unit to ensure fast processing and stable performance. Additionally, the machine is environmentally friendly, safe, efficient, and offers a long service life—earning praise from domestic and international clients alike. It has become a trusted solution in the industry. Scheduled Maintenance for Spiral Ductwork Machine Check Belts and Wheels During operation, belts may wear or break, and wheels may deteriorate over time. It’s essential to regularly inspect and replace these components to maintain the machine’s optimal functionality. Replace Lubricating Oil After a period of use, the existing lubricating oil should be replaced. Before adding new oil, thoroughly clean both the internal and external parts of the machine. The oil change interval should be determined based on machine usage, but an annual replacement is generally recommended or adjusted according to the production workload. Inspect Electrical Wires and Switches Wires and switches may loosen or suffer damage during operation. Regular inspection and timely repairs are crucial. Electrical safety is fundamental to the machine's reliable operation, so proactive checks help eliminate potential hazards. The spiral ductwork machine is a specialized piece of equipment designed to transform metal sheets into spiral ducts of varying shapes and sizes. It plays a key role in sectors such as construction, chemical processing, mining, and agriculture. To ensure stable, long-term operation, the machine requires proper usage and systematic maintenance. Maintenance protocols should be tailored to the machine's operational history and aligned with manufacturer guidelines. Routine inspections, cleaning, and adherence to the operation manual are essential to prevent malfunctions and minimize production disruptions. 在住宅建筑中，使用螺旋管的中央空调系统达到了72.5％的采用率。
