Why do many use spiral ducts in ventilation duct projects?

by:JVTIA     2022-07-18
With the development trend of the manufacturing industry, the spiral air duct machine manufacturing industry is developing in the direction of improving the mold equipment, production process and design products, and the technical performance of the spiral air duct machine in my country may be getting better and better. With the development of technology, the quality regulations of ventilation and air-conditioning projects have been relatively improved. At present, there are many applications of spiral air ducts and spiral circular air ducts, considering the role of ventilation and air-conditioning projects and ash removal transportation. This requires sustainable development in the current technology, choosing strategies for more economical raw materials, physical and mental health and sustainable development, and developing, designing, producing and manufacturing machinery and equipment. At present, the key to the metal air duct method used in the central air-conditioning ventilation duct is the circular air duct and the spiral air duct. The round pipe has high compressive strength and few consumables, but the manufacturing process is complicated and takes up a lot of indoor space; the spiral air duct is convenient to arrange and convenient to produce and process, so it is widely used. There are also mechanical automated productions made of steel chain helical coil inductors, with round and rectangular frames. In order to save indoor space, many spiral ducts are oblate. In natural ventilation and air conditioning system engineering, the frictional resistance of gas fluidity is divided into two categories: one is the viscosity of the gas itself and the pressure loss caused by friction with the wall thickness, that is, the frictional resistance loss along the way; the other One is that when the gas flows through a certain pipeline, the symmetrical flow is damaged, resulting in the change of the size and direction of the water flow, and the loss of kinetic energy caused by the vortex, that is, the loss of part of the frictional resistance. Various air duct methods have their own advantages and disadvantages, and the definitions of arc air ducts are clearly put forward for the places that can be used and the places where they are used. Arc Duct comes from the optimal control improvements for Spiral Duct and Circular Duct. Get rid of the requirement of the large indoor space aspect ratio required by the circular air duct, the spiral air duct consumes raw materials, and the fluid dynamic defect of the spiral air duct makes great use of the indoor space with limited cross-section, saves the consumption of raw materials, reduces dust accumulation, and is easy to clean.
