螺旋风管的用途有哪些
What are the uses of spiral air ducts
送风，包容气脉通达，如送鲜风和排气，这个范围很广，如工场车间，生产施工空气，因为有害气体诞生供给排出露天，又需要把露天空气输送至卧室。这时就要使用流量大而压力小的气氛运送管道，螺旋风管就审度实用，普通情形下任用镀锌铁笛或铁制成的圆管，有腐蚀性及迥殊湿润场所使用不锈钢管；送凉风。常见的是中央空调的管道，这种管道需要加保温材料。螺旋风管可内贴保温材料，外表看来美妙。
Air supply, including fresh air and exhaust, has a wide range, such as workshops, production and construction air. Due to the generation of harmful gases, it is necessary to supply and exhaust outdoor air to the bedroom. At this point, it is necessary to use atmospheric transportation pipelines with high flow rate and low pressure. Spiral air ducts are considered practical, and generally, galvanized iron pipes or circular pipes made of iron can be used. Stainless steel pipes are used in corrosive and humid areas; Send a cool breeze. The common type is the pipes of central air conditioning, which require insulation materials. The spiral air duct can be internally coated with insulation material, which looks beautiful on the outside.
排油烟。饭店、茶楼特设的小房间、宾馆的厨房均有大量油烟产生，需要排出，使用圆形的风管即是油烟囱。在这里，螺旋风管该叫做油烟管；除尘。有些工厂临盆车间繁多尘土，供给特地的除尘装置，个中风流量较大的管道，可使用螺旋风管；散装物料输送。有的工厂的临盆过程中，需要输送松散的颗粒，特别是比重不大的如发泡塑料粒之类的任用螺旋风管造价低、效果好。
Exhaust fumes. Hotels, small rooms specially designed for tea houses, and kitchens in hotels all generate a large amount of oil smoke that needs to be discharged. Circular air ducts are used, which are called oil smoke chimneys. Here, the spiral air duct should be called an oil fume duct; remove dust. Some factories have a large amount of dust in their delivery workshops, and special dust removal devices are provided. For pipelines with large air flow, spiral air ducts can be used; Bulk material transportation. During the delivery process in some factories, loose particles need to be transported, especially spiral air ducts with small specific gravity such as foam plastic particles, which have low cost and good effects.
