The advantage of spiral duct in ventilation industry
The ventilation equipment products are widely used in shipbuilding, ventilation, purification, Bridges, dust removal, airport, tunnel construction, WINYING Machinery Manufacturing Co., Ltd after years of research introduction of Swiss technology development of spiral wind mill has reached the domestic high-end level, since the market itself has excellent performance and low cost, application in the ventilation and air conditioning system continuously promoted, volumes of 85-1400 mm in diameter, processing of thickness 0.4– 1.2 mm, main use is as follows:
(1) Dust removal system: The dust removal device can be collected and transported with spiral air duct.
(2) Exhaust fume system: a large amount of fume is produced in the kitchen of restaurants, restaurants and hotels, which needs to be discharged. Spiral air duct is suitable, strong, economical and practical.
(3) Air conditioning system: Spiral duct machine can be affixed with insulation materials, beautiful appearance.
(4) Bulk material conveying: pneumatic conveying system can be used to transport some fine and loose material particles with spiral air duct, which has low cost and good effect.
(5) Ventilation system: supply fresh air and exhaust, discharge harmful gases out of the room, and bring fresh air to the room.In general, ventilation systems have a high flow rate and require the use of air ducts with low resistance to save cost and operating costs – spiral air ducts are the most suitable.Use galvanized iron pipes in general, stainless steel pipes in corrosive and especially damp places.
Spiral duct features:
(1) : With the same length, the number of flange connections is less, and the bee performance is better than the rectangular duct, which greatly improves the ventilation quality of the system.
(2) : With the same thickness of the sample and the same pipe diameter, the spiral duct has high strength.
(3) : Under the same cross section, the structural tension of the circular duct is more reasonable than that of the rectangular duct, which greatly improves the rigidity of the duct and significantly reduces the chatter noise.
(4) : The air duct is round in appearance and attractive in appearance.
(1) : High efficiency construction, used in large projects with short construction period.
(2) : No processing on the construction site is required to reduce on-site operation personnel and management procedures.
(3) : Mechanized production, fast and efficient.
(4) : Compared with the rectangular duct, the matching special duct has a high degree of standardization, simple hoisting and greatly reduced error probability.
(5) : Single lifting point of spiral duct with small diameter, fast and efficient hoisting.
(6) : The number of connecting flanges is small, and the hoisting and connecting workload is reduced by about 50%.
(1) : The hoisting efficiency during construction is twice that of the rectangular duct.
(2) : Under the same conditions, the low-speed air supply and exhaust of the air duct can be changed into high-speed air supply and exhaust. The system design can reduce the total amount of the air duct, which is not only economical, but also saves space.
(3) : Under the same conditions, the full-shape auxiliary materials have simple results, less quantity, and 30% reduction in the cost of installation auxiliary materials
(4) : According to the standard specification, the thickness of the plate can be reduced by 10-15% with the same pipe diameter.
