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.
螺旋风管的优点有哪些
What are the advantages of spiral ducts
产品配套性好、标准化水准高；密闭性强；通风消耗小；通风噪声小，圆管优于边长相等的的钢管。
Good product compatibility and high standardization level; Strong airtightness; Low ventilation consumption; Ventilation noise is low, and circular pipes are superior to steel pipes with equal sides.
工厂检测轻易；抗均衡外压（负压）程序；材料省；安装方便，连接点少，安设空间位置小，安装成本低。
Easy factory inspection; Anti equilibrium external pressure (negative pressure) program; Ministry of Materials; Easy installation, few connection points, small installation space, and low installation cost.
安设全部结构美观，档次高；平常养育冲洗方便；断面湿周小、沿程阻力小、能量损失更小；全机械加工，一趟成型无需二次加工。
All structures installed are aesthetically pleasing and of high grade; Easy to raise and rinse in daily life; Small wet circumference of the cross-section, small resistance along the way, and smaller energy loss; Fully mechanical processing, no need for secondary processing in one molding process.
采纳高速飞式切割机，外径与内径之平均值精确度高；采用缩径套接、套管互接、法兰互接、束带互接四种方式，安装更加方便；管外保温量优于矩形风管。
Adopting a high-speed flying cutting machine, the average accuracy of outer diameter and inner diameter is high; Four methods are adopted: reducing sleeve connection, sleeve connection, flange connection, and strap connection, making installation more convenient; The insulation quality outside the pipe is better than that of rectangular air ducts.
