關(guān)于濟(jì)南通風(fēng)管道的首要裝置程序，咱們大概先要清楚的是通風(fēng)管道拼裝：假如風(fēng)管較短，可一次在地上拼裝而成，當(dāng)風(fēng)管較長時(shí)，可視裝置場所的狀況，在地上分段拼裝。拼裝時(shí)應(yīng)盡量調(diào)整風(fēng)道的中間度和水平度，防止風(fēng)管歪曲或上下起波，擺布擺龍，每段風(fēng)道不宜超越10m.拼裝時(shí)，墊片應(yīng)墊平，法蘭螺栓應(yīng)均勻擰緊，螺母帽均朝向同一方向。

Regarding the primary installation procedure for Jinan ventilation ducts, we should first clarify the assembly of ventilation ducts: if the ducts are short, they can be assembled on the ground in one go. When the ducts are long, they can be segmented and assembled on the ground according to the conditions of the installation site. During assembly, the centrality and levelness of the air duct should be adjusted as much as possible to prevent the duct from distorting or rippling up and down, and the length of each section of the duct should not exceed 10m. During assembly, the gasket should be leveled, the flange bolts should be evenly tightened, and the nut caps should be facing the same direction.

風(fēng)道調(diào)直：就位在支架上的風(fēng)道，應(yīng)撥正方位，調(diào)整風(fēng)道橫平豎直，然后再按圖集需求固定。

Air duct straightening: The air duct placed on the bracket should be aligned, adjusted horizontally and vertically, and then fixed according to the requirements of the atlas.

通風(fēng)管道就位：風(fēng)管就位前應(yīng)查看悉數(shù)支架的水乎度和標(biāo)高、查看支架的結(jié)實(shí)程度，風(fēng)管就位可選用直接和吊具兩種辦法。對(duì)風(fēng)管斷面較小，又方位較低的可選用人工就位辦法，只需搭設(shè)簡便腳手架即可。

Ventilation duct positioning: Before positioning the air duct, the water level and elevation of all supports should be checked, and the firmness of the supports should be checked. There are two methods for positioning the air duct: direct and lifting. For ducts with small cross-section and low orientation, manual positioning can be used, which only requires the installation of simple scaffolding.

當(dāng)通風(fēng)管道斷面較大且管段較長時(shí)，可選用滑輪、倒鏈、大繩等辦法吊裝。腳手架應(yīng)沿其風(fēng)道長度方向搭設(shè)，高度和方位應(yīng)合適施工操作，吊裝次序應(yīng)先干管后支、立管，吊起時(shí)，吊點(diǎn)應(yīng)結(jié)實(shí)，兩吊點(diǎn)應(yīng)均勻受力。別的咱們大概曉得為了便于風(fēng)道就位，通常多選用將風(fēng)道吊在腳手架上，然后再將其抬放在風(fēng)道支架上的辦法。

When the cross-section of the ventilation pipeline is large and the pipe section is long, methods such as pulleys, chain blocks, and large ropes can be used for lifting. Scaffolding should be erected along the length direction of its air duct, and the height and orientation should be suitable for construction operations. The lifting sequence should start with the main pipe and then support and stand pipe. When lifting, the lifting points should be sturdy, and the two lifting points should be evenly stressed. We probably know that in order to facilitate the positioning of the air duct, we usually choose to hang the air duct on a scaffold and then lift it onto the air duct bracket.

當(dāng)風(fēng)道輸送一般氣體時(shí)，對(duì)黑鋼板風(fēng)道應(yīng)進(jìn)行除銹、刷防銹漆處理，對(duì)含塵氣體可噴涂防磨損保護(hù)層，當(dāng)周圍環(huán)境空氣濕度較大時(shí)，風(fēng)道外壁需做防腐蝕、防銹處理。對(duì)輸送高溫、高濕氣體的鍍鋅鋼板風(fēng)道內(nèi)壁宜噴刷磷化底漆或其他耐蝕涂料。在風(fēng)道輸送高溫氣體或低溫空氣時(shí)，風(fēng)道外壁應(yīng)做保溫(保冷)處理。，

When conveying general gas in the air duct, the black steel plate air duct should be treated with rust removal and anti rust paint. For dusty gases, an anti wear protective layer can be sprayed. When the surrounding air humidity is high, the outer wall of the air duct needs to be treated with anti-corrosion and rust prevention. The inner wall of galvanized steel plate air ducts conveying high-temperature and high humidity gases should be sprayed with phosphating primer or other corrosion-resistant coatings. When conveying high-temperature gas or low-temperature air in the air duct, the outer wall of the air duct should undergo insulation (cold insulation) treatment.,

通風(fēng)管道加工是用來管道進(jìn)行室內(nèi)或者是封閉空間通風(fēng)的，通風(fēng)的形式分為好幾種自然通風(fēng)要有必備的兩個(gè)因素就是風(fēng)力和室內(nèi)外溫差。利用自然形式的通風(fēng)是經(jīng)濟(jì)和有效的通風(fēng)方法，不僅可以節(jié)省能源、降低工程的造價(jià)，同時(shí)還沒有噪聲污染，也沒有不良的感覺。還有什么事項(xiàng)就來我們網(wǎng)站http://m.hwzxw.net咨詢吧！

Ventilation duct processing is used for indoor or enclosed space ventilation through ducts. There are several forms of ventilation. Firstly, natural ventilation requires two essential factors: wind force and indoor/outdoor temperature difference. The use of natural forms of ventilation is an economical and effective method of ventilation, which can not only save energy and reduce engineering costs, but also have no noise pollution or negative feelings.
