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.

　　白口铸铁加工材料应具有导热性小、保温、耐腐蚀、防火等性能。

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

　　通风管道设计时，如有可能，不宜过长;管径要粗，形状要圆。

　　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.

　　支管半径不得小于主管半径的1/2 ~ 1/3，以方便通风管道的加工。

　　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.

　　通风管道的设计应尽量弯曲。

　　Ventilation pipes should be designed as bent as possible.

　　通风管道设计弯头应尽可能小，两个弯头之间的距离应较大。当两个弯头之间的距离是管径的三倍时，阻力增加约80%。当它是5倍的时候，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%.

　　尽量直立或倾斜放置，设置清洗口，连接应紧密，不漏水，并易于维修。

　　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.

　　重庆通风管道效率高:有效去除不同粒径的烟尘颗粒，净化效率高，从根本上了污染转移问题。

　　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. 灵活性:模块化机组可灵活组合，机组数量可根据不同排烟能力和净化速率要求进行自适应调整。

　　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.:采用的数控设备，生产精细，装配结构合理，长期运行后运行效率高。

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

　　4. :系统设计良好，可配备检修门，及时检测风管运行状态。使用可靠，大大提高了操作的系数。

　　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. 稳定性:不锈钢风管本身采用焊接工艺，并经过严格检测，可根据客户要求装配各种实用方案(有两种夹紧、法兰)，能保证设备的稳定运行。

　　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.

　　人们对生活质量和环境的要求越来越高。当建筑物和一些工厂建造时，将考虑通风系统。特别是在工厂，只有良好的通风才能保证工厂工人的，为以后的工作提供良好的环境条件。对于风管加工，厂家的选择是首要考虑的。

　　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.

　　管道处理的种类是什么?通风管道用于输送空气管道系统,管道处理需要注意什么管道输送空气管,有不同的形状和材料,管道,根据截面的形状可分为圆形、矩形和椭圆管,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.

　　按材料分为金属材料和复合风道。根据管道的不同特点和应用环境选择不同类型的管道。通风管道广泛应用于各行各业，是必不可少的通风设备。

　　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.
