专注通风管道加工·排烟罩

1. Balanced layout of spiral air ducts for underground works.

地下工程螺旋风管的分布特点要求施工前深化设计，螺旋风管加工综合布置各种螺旋风管等管道，确保螺旋风管的安装和施工在有限的空间内顺利完成。施工前，对所有断面进行现场测量，绘制管道综合布置图和断面图，准确定位每根风管和支吊架的位置。

The distribution characteristics of spiral air ducts in underground engineering require the deepening design before construction, Xi'an ventilation duct, Xi'an ventilation duct processing, Xi'an spiral air duct processing, Xi'an ventilation duct processing factory, ventilation duct, spiral air duct processing, and comprehensive arrangement of various spiral air ducts and other pipes to ensure that the installation and construction of spiral air ducts can be successfully completed in a limited space. Before construction, all sections shall be measured on site, the comprehensive layout and section drawing of the pipeline shall be drawn, and the position of each air duct and support hanger shall be accurately located.

用3dmax对部分通道、大厅等部位建立直观的管道布置立体模型。根据管道综合布置图和截面图建立模型，通过立体模型发现管道综合布置图和截面图的问题，达到合理一致。

Use 3dmax to build an intuitive three-dimensional model of pipeline layout for some passages, halls and other parts. The model is established according to the comprehensive layout and cross-section of the pipeline, and the problems in the comprehensive layout and cross-section of the pipeline are found through the three-dimensional model to achieve reasonable consistency.

将不同角度的立体效果图和各截面的截面图制作成图纸，挂在施工现场的相应部位，使施工人员通过效果图直观地了解管道布置，并根据截面图进行施工，大大提高了技术交底的质量和效率，保证了施工的顺利进行，减少了协调工作量，提高了施工效率。

The three-dimensional renderings from different angles and the sectional drawings of each section are made into drawings and hung on the corresponding parts of the construction site, so that the construction personnel can intuitively understand the pipeline layout through the renderings and carry out the construction according to the sectional drawings, which greatly improves the quality and efficiency of the technical disclosure, ensures the smooth progress of the construction, reduces the coordination workload and improves the construction efficiency.

2.螺旋风管及管件的生产。

2. Production of spiral air duct and pipe fittings.

地下通风工程采用自动生产线生产螺旋风管，速度快，质量好，性能稳定，使用寿命长。螺旋风管可采用不锈钢带和镀锌钢带生产。弯头、三通等各类管件采用等离子切割机下料，直接输入管件的相关参数即可快速切割出管件展开板。缝纫焊机闭合板和拼接各种金属板，特别是在拼接镀锌板时，不会损坏镀锌层和接口。

The underground ventilation project adopts automatic production line to produce spiral air duct, which is fast, good quality, stable performance and long service life. Spiral air duct can be produced with stainless steel strip and galvanized steel strip. Various pipe fittings such as elbows and tees are cut by plasma cutting machine, and the pipe fitting expansion plate can be quickly cut by directly inputting the relevant parameters of the pipe fitting. The seam welding machine will not damage the galvanized layer and interface when closing the plate and splicing various metal plates, especially when splicing the galvanized plate.

平整适用于各种翻边加工。圆形弯头成型机自动咬合弯头，速度快，密实光滑。所有风管及管件的生产基本实现了机械化自动化标准化，生产效率高，质量硬，外观美观，节省了大量的人力和材料。

Flatness is applicable to various flanging processes. The circular elbow forming machine automatically bites the elbow, which is fast, dense and smooth. The production of all air ducts and pipe fittings has basically realized mechanization, automation and standardization, with high production efficiency, hard quality and beautiful appearance, saving a lot of manpower and materials.
