Application of spiral duct fan
Spiral air duct machine is a thin-walled pipe with spiral seam made of metal strip material roll. It is round, no welding, no air leakage and no water leakage. It is mostly used for air supply and bulk material transportation to replace the traditional white iron pipe (i.e. manual seam iron pipe). It is a kind of air duct. The full mechanism straight pipe does not need to be knocked manually. Its main uses are as follows:
1) Air supply, including ventilation, such as fresh air supply and exhaust, covers a wide range, such as the air in factories, workshops and production sites, which needs to be discharged outdoors due to the generation of harmful gases, and the outdoor air needs to be transported indoors. At this time, the air transmission pipeline with large flow and low pressure shall be used, and the spiral air duct is applicable. Generally, galvanized iron pipe shall be used, and stainless steel pipe shall be used in corrosive and particularly humid places.
2) Send cold air. The common is the air-conditioning pipeline, which needs to add thermal insulation materials. Spiral air duct can be pasted with thermal insulation material, which looks beautiful.
3) Exhaust oil fume. The kitchens of hotels, restaurants and hotels produce a large amount of oil fume and need to be discharged. The use of circular air duct is oil chimney. Here, spiral air duct should be called oil fume pipe.
4) Dust removal. There is a lot of dust in the production workshops of some factories, which requires special dust removal devices. Spiral air ducts can be used for pipes with large air flow.
5) Bulk material handling. In the production process of some factories, loose particles need to be transported, especially those with small proportion, such as foamed plastic particles. The spiral air duct has low cost and good effect.
