通風(fēng)管的底切和四角需要用密封膠密封。此外，通氣管接頭的密封面應(yīng)設(shè)置在通氣管壁的正壓側(cè)。
The undercut and four corners of the ventilation pipe need to be sealed with sealant. In addition, the sealing surface of the vent pipe joint should be set on the positive pressure side of the vent pipe wall.
在風(fēng)管加工過程中，通風(fēng)管道不能設(shè)置加強(qiáng)框架或加強(qiáng)筋，因?yàn)檫@會對通風(fēng)管道的質(zhì)量產(chǎn)生一定的影響。
In the process of air duct processing, the ventilation duct can not be set with reinforcing frame or rib, because it will have a certain impact on the quality of the ventilation duct.
風(fēng)管加工不能采用“S”形切割和“C”形直角切割的連接方式。此外，一些特殊的通風(fēng)管道不能堵塞。
S-shaped cutting and C-shaped right angle cutting can't be used in air duct processing. In addition, some special ventilation ducts should not be blocked.

1、風(fēng)管的制造和安裝應(yīng)按照設(shè)計(jì)圖紙、合同和相關(guān)技術(shù)標(biāo)準(zhǔn)進(jìn)行。任何變更一定要附有設(shè)計(jì)或合同變更通知或技術(shù)批準(zhǔn)簽證。
1. The manufacture and installation of air duct shall be in accordance with the design drawings, contract and relevant technical standards. Any change must be accompanied by design or contract change notice or technical approval visa.
2、風(fēng)管系統(tǒng)施工前，施工單位應(yīng)與建設(shè)單位、監(jiān)理單位、總承包商和設(shè)計(jì)單位進(jìn)行協(xié)調(diào)。檢查風(fēng)管及其他管道的位置和方向，檢查預(yù)留孔的安裝。施工應(yīng)與土建工程和其他工種相協(xié)調(diào)。
2. Before the construction of air duct system, the construction unit shall coordinate with the construction unit, supervision unit, general contractor and design unit. Check the position and direction of air duct and other pipes, and check the installation of reserved holes. Construction shall be coordinated with civil engineering and other types of work.
3、風(fēng)管生產(chǎn)安裝中使用的板材、型材等主要成品應(yīng)符合設(shè)計(jì)及相關(guān)產(chǎn)品國家現(xiàn)行標(biāo)準(zhǔn)，濟(jì)南通風(fēng)管道并有出廠檢驗(yàn)證書。材料進(jìn)場應(yīng)按現(xiàn)行國家相關(guān)標(biāo)準(zhǔn)進(jìn)行驗(yàn)收。
3. The main finished products such as plates and profiles used in the production and installation of air duct shall meet the current national standards for design and related products, and Jinan ventilation duct shall have factory inspection certificate. Materials entering the site shall be accepted according to the current national standards.
4、當(dāng)風(fēng)管與風(fēng)機(jī)連接時(shí)，應(yīng)在進(jìn)出風(fēng)口處加軟接頭，其軟接頭的斷面尺寸應(yīng)與風(fēng)機(jī)進(jìn)出風(fēng)口一致。軟管接頭一般可采用帆布、人造革等材料，軟管長度不宜小于200，松緊度應(yīng)適宜，柔性軟管可緩沖風(fēng)機(jī)的振動(dòng)。
4. When the air duct is connected with the fan, a soft joint shall be added at the air inlet and outlet, and the section size of the soft joint shall be consistent with the air inlet and outlet of the fan. Generally, the hose joint can be made of canvas, artificial leather and other materials, the length of the hose should not be less than 200, the tightness should be appropriate, and the flexible hose can buffer the vibration of the fan.
