发布人：   发布时间：2024-11-12 10:43:18

　　材料选择 ：

　　Material selection:

　　铁皮风管主要采用镀锌钢板材料，其厚度必须符合相关标准要求。例如，直径小于600mm的风管，镀锌钢板厚度不应小于0.6mm；直径大于600mm的风管，镀锌钢板厚度不应小于0.8mm。

　　The iron sheet air duct is mainly made of galvanized steel plate material, and its thickness must meet the requirements of relevant standards. For example, for air ducts with a diameter less than 600mm, the thickness of galvanized steel sheet should not be less than 0.6mm; For air ducts with a diameter greater than 600mm, the thickness of galvanized steel plate should not be less than 0.8mm.

　　材料应具有良好的工艺性能，表面平整光滑，不得有裂纹、折皱、气泡、夹渣等缺陷。

　　The material should have good processability, a flat and smooth surface, and no defects such as cracks, wrinkles, bubbles, slag inclusions, etc.

　　尺寸设计 ：

　　Size design:

　　铁皮风管的尺寸应符合设计要求，包括内外尺寸、弯头半径、槽形尺寸等，以确保与其他设备或管道的配合良好，并满足风量、阻力和噪音等方面的要求。

　　The size of the iron sheet air duct should meet the design requirements, including internal and external dimensions, bend radius, groove size, etc., to ensure good coordination with other equipment or pipelines and meet the requirements of air volume, resistance, and noise.

　　制作要求 ：

　　Production requirements:

　　焊缝应作外观检查，不应有气孔、砂眼、夹渣、裂纹等缺陷，焊接后钢板的变形应矫正。

　　The weld seam should undergo visual inspection and should not have defects such as pores, sand holes, slag inclusions, cracks, etc. The deformation of the steel plate after welding should be corrected.

　　保温层应使用不燃或难燃材料，具有防腐、防潮等性能，且保温层边部接合部位应采用梯台或榫槽结构，用树脂粘贴。

　　The insulation layer should be made of non combustible or flame-retardant materials, with anti-corrosion, moisture-proof and other properties. The joints at the edges of the insulation layer should be made of ladder or mortise and tenon structures, and glued with resin.

　　风管的风道与风口接合应使用带保温层的软管连接，风道安装应平直，主风道安装不直度≤1.5㎜/m，不平度≤1㎜/m。

　　The connection between the air duct and the air outlet should be made using a flexible hose with insulation layer. The installation of the air duct should be straight, and the installation straightness of the main air duct should be ≤ 1.5mm/m, and the unevenness should be ≤ 1mm/m.

　　配件和偏差 ：

　　Accessories and deviations:

　　制作铁皮风管和配件时，外径或外边长的允许偏差为：小于或等于300㎜为-1㎜；大于300㎜为-2㎜。

　　When making iron sheet air ducts and accessories, the allowable deviation for the outer diameter or outer edge length is -1mm if it is less than or equal to 300mm; Greater than 300mm is -2mm.

　　风道系统内所有直角转弯处均安装消声弯头，消声弯头内设镀锌铁板导流片。

　　All right angle bends in the air duct system are equipped with soundproof elbows, which are fitted with galvanized iron plate guide vanes.

　　安装要求 ：

　　Installation requirements:

　　风管安装时，应按设计要求确定安装位置和固定方式，确保安装牢固、接口严密，避免出现摇晃或松动现象。

　　When installing air ducts, the installation position and fixing method should be determined according to the design requirements to ensure firm installation, tight interfaces, and avoid shaking or loosening.

　　对于有特殊要求的风管，如防火、防爆等，应按照相关规定进行特别处理和安装。

　　For ducts with special requirements, such as fire and explosion prevention, special treatment and installation should be carried out in accordance with relevant regulations.

　　质量检验 ：

　　Quality inspection:

　　铁皮风管制作完成后，应进行质量检验，确保风管的材料、尺寸、外观质量和连接方式等符合设计要求和相关标准规定。

　　After the completion of the iron sheet air duct production, quality inspection should be carried out to ensure that the material, size, appearance quality, and connection method of the air duct meet the design requirements and relevant standards.

　　其他细节 ：

　　Other details:

　　风管内严禁有杂物或其他管线穿越，并做好清洁和保护工作。

　　No debris or other pipelines are allowed to pass through the air duct, and cleaning and protection measures must be taken.

　　镀锌铁皮风管损耗标准是在15%到20%左右，具体也要考虑到铁皮风管的直径和整体的展开面积。

　　The national standard for the loss of galvanized iron sheet air ducts is around 15% to 20%, taking into account the diameter and overall unfolding area of the iron sheet air ducts.
