螺旋风管的用途是什么？

What is the purpose of the spiral duct?

螺旋风管是用金属带料卷制成螺旋形咬缝的薄壁管，圆形，无焊接，不漏气，不漏水，多用于送风和散装物料输送，代替传统的白铁管（即手工咬缝铁管）。是风管的一种，全机制，直管无需手工敲打。其主要用途如下：

The spiral air pipe is a thin-walled pipe with spiral bite seam, which is made of metal tape. It is round, weldless, leaky and water-tight. It is mainly used for air supply and bulk material transportation instead of the traditional white iron pipe (i.e. manual bite seam iron pipe). It is a kind of air duct, full mechanism, straight pipe without manual knocking. Its main uses are as follows:

（1）送风

(1) air supply

包括通气，如送鲜风和排气，这个范围很广，如工厂车间，生产场地空气，由于有害气体产生需要排出室外，又需要把室外空气输送至室内。这时就要使用流量大而压力小的空气输送管道，螺旋风管就最适用，一般情况下使用镀锌铁管，有腐蚀性及特别潮湿场所使用不锈钢管。

Including ventilation, such as fresh air supply and exhaust, this range is very wide, such as factory workshop, production site air, due to the production of harmful gases need to be discharged outdoors, but also the need to transport outdoor air indoors. At this time, the use of large flow and pressure of small air pipeline, spiral duct is the most suitable, in general use of galvanized iron pipe, corrosion and particularly humid places using stainless steel pipe.

(2) 送冷风

(2) send cold air

送冷风。最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，外表看来美观。

Send a cold wind. The most common is the central air conditioning pipeline, this piping needs to add the heat preservation material. The spiral duct can be attached with thermal insulation material and looks beautiful.

(3) 排油烟

(3) lampblack

饭店、酒楼、宾馆的厨房均有大量油烟产生，需要排出，使用圆形的风管就是油烟囱。在这里，螺旋风管该叫做油烟管。

Hotel, restaurant, hotel kitchen have a lot of cooking fumes generated, need to be discharged, the use of circular ducts is the oil chimney. Here, the spiral duct is called lampblack pipe.

(4) 除尘

(4) dust removal

有些工厂生产车间很多尘埃，需要专门的除尘装置，其中风流量较大的管道，可使用螺旋风管。

In some factories, there is a lot of dust in the workshop, and special dust removal equipment is needed. The pipe with large air flow can use spiral duct.

(5) 散装物料输送

(5) bulk material transportation

有些工厂的生产过程中，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使用螺旋风管造价低、效果好。

Some factories need to transport loose particles in the production process, especially small proportion of such as foamed plastic particles such as the use of spiral duct cost is low, the effect is good.
