　　We are all familiar with white iron processing ventilation equipment, ventilation duct is an important part of ventilation equipment, connecting fan, air treatment equipment and air inlet. In the design of ventilation pipeline, attention should be paid to the problem of resistance in the ventilation pipeline, and the resistance should be reduced as far as possible in the design.

　　白口鑄鐵加工材料應(yīng)具有導(dǎo)熱性小、保溫、耐腐蝕、防火等性能。

　　White cast iron processing materials should have low thermal conductivity, thermal insulation, corrosion resistance, fire resistance and other properties.

　　通風(fēng)管道設(shè)計時，如有可能，不宜過長;管徑要粗，形狀要圓。

　　When designing ventilation pipes, if possible, they should not be too long; the diameter of the pipes should be thick and the shape should be round.

　　支管半徑不得小于主管半徑的1/2 ~ 1/3，以方便通風(fēng)管道的加工。

　　The radius of branch pipe should not be less than 1/2 to 1/3 of the radius of main pipe to facilitate the processing of ventilation pipe.

　　通風(fēng)管道的設(shè)計應(yīng)盡量彎曲。

　　Ventilation pipes should be designed as bent as possible.

　　通風(fēng)管道設(shè)計彎頭應(yīng)盡可能小，兩個彎頭之間的距離應(yīng)較大。當(dāng)兩個彎頭之間的距離是管徑的三倍時，阻力增加約80%。當(dāng)它是5倍的時候，它只增加了30%。

　　The design elbow of ventilation pipeline should be as small as possible, and the distance between the two elbows should be large. When the distance between the two elbows is three times the diameter of the pipe, the resistance increases by about 80%. When it was five times that, it only increased by 30%.

　　盡量直立或傾斜放置，設(shè)置清洗口，連接應(yīng)緊密，不漏水，并易于維修。

　　Place it upright or oblique as far as possible. Set up a cleaning port. The connection should be tight, water-tight and easy to maintain.

　　重慶通風(fēng)管道效率高:有效去除不同粒徑的煙塵顆粒，凈化效率高，從根本上解決了污染轉(zhuǎn)移問題。

　　Chongqing Ventilation Pipeline has high efficiency: it can effectively remove smoke and dust particles of different sizes, and has high purification efficiency, which fundamentally solves the problem of pollution transfer.

　　2. 靈活性:模塊化機組可靈活組合，機組數(shù)量可根據(jù)不同排煙能力和凈化速率要求進行自適應(yīng)調(diào)整。

　　2. Flexibility: Modular units can be combined flexibly, and the number of units can be adjusted adaptively according to the requirements of different exhaust capacity and purification rate.

　　3.先進:采用先進的數(shù)控設(shè)備，生產(chǎn)精細，裝配結(jié)構(gòu)合理，長期運行后運行效率高。

　　3. Advanced: advanced numerical control equipment, fine production, reasonable assembly structure, long-term operation of high efficiency.

　　4. 安全:安全系統(tǒng)設(shè)計良好，可配備檢修門，及時檢測風(fēng)管運行狀態(tài)。使用安全可靠，大大提高了操作的安全系數(shù)。

　　4. Safety: The safety system is well designed, and can be equipped with overhaul doors to detect the operation status of air ducts in time. It is safe and reliable to use and greatly improves the safety factor of operation.

　　5. 穩(wěn)定性:不銹鋼風(fēng)管本身采用焊接工藝，并經(jīng)過嚴(yán)格檢測，可根據(jù)客戶要求裝配各種實用解決方案(有兩種夾緊、法蘭)，能保證設(shè)備的穩(wěn)定運行。

　　5. Stability: Stainless steel air duct itself adopts welding technology, and after strict testing, can be assembled according to customer requirements of various practical solutions (two kinds of clamping, flange), to ensure the stable operation of the equipment.

　　人們對生活質(zhì)量和環(huán)境的要求越來越高。當(dāng)建筑物和一些工廠建造時，將考慮通風(fēng)系統(tǒng)。特別是在工廠，只有良好的通風(fēng)才能保證工廠工人的安全，為以后的工作提供良好的環(huán)境條件。對于風(fēng)管加工，廠家的選擇是首要考慮的。

　　People are demanding higher and higher quality of life and environment. Ventilation systems will be considered when building and some factories are built. Especially in factories, only good ventilation can ensure the safety of factory workers and provide good environmental conditions for future work. For air duct processing, the choice of professional manufacturers is the first consideration.

　　管道處理的種類是什么?通風(fēng)管道用于輸送空氣管道系統(tǒng),管道處理需要注意什么管道輸送空氣管,有不同的形狀和材料,管道,根據(jù)截面的形狀可分為圓形、矩形和橢圓管,是生活中常用的矩形管。

　　What are the types of pipeline treatment? Ventilation pipes are used to transport air pipeline system. What kind of pipeline should be paid attention to in pipeline treatment? There are different shapes and materials. Pipes can be divided into circular, rectangular and elliptical pipes according to the shape of cross section. They are commonly used in life.

　　按材料分為金屬材料和復(fù)合風(fēng)道。根據(jù)管道的不同特點和應(yīng)用環(huán)境選擇不同類型的管道。通風(fēng)管道廣泛應(yīng)用于各行各業(yè)，是必不可少的通風(fēng)設(shè)備。

　　According to the material, it can be divided into metal material and composite duct. Different types of pipelines are selected according to their different characteristics and application environment. Ventilation pipes are widely used in all walks of life and are indispensable ventilation equipment.
