通風(fēng)管道是一種負(fù)責(zé)通風(fēng)與空調(diào)工程，采用金屬、非金屬薄板或其它材料制作而成的，主要用于空氣流通，在一些大型場所中，通風(fēng)管道有著廣泛的應(yīng)用，主要應(yīng)用范圍是工業(yè)與建筑工程，酒店、賓館、商場、工廠及寫字樓的空調(diào)系統(tǒng)。小編為大家總結(jié)了山東通風(fēng)管道的性能指標(biāo)，期待您的關(guān)注。
Ventilation duct is a kind of ventilation and air conditioning engineering, which is made of metal, non-metal sheet or other materials. It is mainly used for air circulation. In some large places, ventilation duct has a wide range of applications, mainly in industrial and construction engineering, hotel, hotel, shopping mall, factory and office building central air conditioning system. Xiao Bian summarized the performance index of Shandong ventilation pipeline for you, looking forward to your attention.
1、工作壓力：系統(tǒng)風(fēng)管總風(fēng)管處設(shè)計(jì)的大的工作壓力。
1. Working pressure: the large working pressure designed at the main air duct of the system.
2、允許漏風(fēng)量：按風(fēng)管系統(tǒng)類別所規(guī)定平均單位面積、單位時間內(nèi)的大允許漏風(fēng)量。
2. Allowable air leakage: large allowable air leakage per unit area and per unit time according to the category of air duct system.
3、漏風(fēng)量：通風(fēng)管道系統(tǒng)中，在某一靜壓下通過風(fēng)管本體結(jié)構(gòu)及其接口，單位時間內(nèi)泄出或滲入的空氣體積量。
3. Air leakage: the volume of air leaked or infiltrated per unit time through the structure and interface of the air duct body under a certain static pressure in the ventilation duct system.
濟(jì)南通風(fēng)管道強(qiáng)度高、剛性好，通風(fēng)阻力小，適應(yīng)于各種領(lǐng)域。為了保障工業(yè)及民用建筑的正常通風(fēng)，通風(fēng)管道必須滿足高性能、長使用壽命的要求，這對其加工材質(zhì)就有了較高的要求。一般鋼板、鍍鋅板、不銹鋼材質(zhì)在通風(fēng)管道制作中比較常用。如果你想對通風(fēng)管道進(jìn)行更深入的了解，歡迎經(jīng)常來訪本站。
Jinan ventilation pipeline has high strength, good rigidity and small ventilation resistance, which is suitable for various fields. In order to ensure the normal ventilation of industrial and civil buildings, the ventilation pipe must meet the requirements of high performance and long service life, which has higher requirements for its processing materials. General steel, galvanized steel, stainless steel materials are commonly used in the production of ventilation pipes.

濟(jì)南通風(fēng)管道制作前的準(zhǔn)備工作：
The preparation work before the manufacture of Jinan ventilation pipe is as follows
1、制作風(fēng)管前，首先要檢查采用的材料是否符合質(zhì)量要求，是否有出廠合格證明書或質(zhì)量鑒定文件。若無上述證明文件則應(yīng)進(jìn)行外觀檢查，并應(yīng)符合下列要求：
1. Before making air duct, it is necessary to check whether the materials used meet the quality requirements and whether there are factory certificates or quality appraisal documents. If there is no such certificate, visual inspection shall be conducted and the following requirements shall be met:
(1)板材表面應(yīng)平整，厚度應(yīng)均勻，無凸凹及明顯的壓傷現(xiàn)象，并不得有裂紋、砂眼及、刺邊和銹蝕情況;
(1) The surface of the plate shall be flat, the thickness shall be uniform, and there shall be no convex concave and obvious crush, cracks, sand holes, burrs and corrosion;
(2)型鋼應(yīng)該等型、均勻，不應(yīng)有裂紋、氣泡、窩穴及其它影響質(zhì)量的缺陷;
(2) The section steel shall be of equal shape and uniform without cracks, bubbles, pits and other defects affecting the quality;
(3)其它材料不能因具有問題導(dǎo)致成品強(qiáng)度的降低或影響其使用效能。
(3) Other materials should not reduce the strength of the finished product or affect its use efficiency due to problems.
2、風(fēng)管和配件表面平整、圓弧均勻、縱向接縫應(yīng)錯開;咬口縫應(yīng)緊密，寬度均勻。焊縫應(yīng)作外觀檢查，不應(yīng)有氣孔、砂眼、夾渣、裂紋等缺陷，焊接后鋼板的變形應(yīng)矯正。
2. The surface of air duct and accessories shall be smooth, the arc shall be uniform, and the longitudinal joints shall be staggered; The bite joint shall be tight and uniform in width. The weld shall be inspected visually, and there shall be no air hole, sand hole, slag inclusion, crack and other defects. The deformation of steel plate after welding shall be corrected.
3、制作金屬風(fēng)管和配件，外徑或外邊長的允許偏差，其中制作法蘭，圓形法蘭內(nèi)徑或矩形法蘭內(nèi)邊尺寸允許偏差為+2㎜，不平度不應(yīng)大于2㎜。
3. The allowable deviation of outer diameter or outer edge length for manufacturing metal air duct and fittings is + 2mm for manufacturing flange, inner diameter of circular flange or inner edge size of rectangular flange, and the unevenness shall not be greater than 2mm.
4、風(fēng)道系統(tǒng)內(nèi)所有直角轉(zhuǎn)彎處均安裝消聲彎頭，消聲彎頭內(nèi)設(shè)鍍鋅鐵板導(dǎo)流片。
4. All right angle bends in the air duct system are installed with silencing elbows, and galvanized iron sheet deflectors are set in the silencing elbows.
