通风管道和风管的制作和安装中常用的材料和其他材料应符合设计和实施标准，那么下面来讲讲通风管道效果是怎样的吧。
Common materials and other materials used in the fabrication and installation of ventilation ducts and air ducts shall comply with the design and implementation standards, so let's talk about the effect of ventilation ducts.
1、有机废气从通风管道排出
1. Organic waste gas is discharged from the ventilation duct
饭店、宾馆的厨房会产生大量的厨房油烟，必须排尽。通风管道是专门的污水处理机械设备。
The kitchens of restaurants and hotels will produce a lot of kitchen oil smoke, which must be exhausted. Ventilation duct is a special mechanical equipment for sewage treatment.
2.通风管道送冷空气
2. cold air supplied by ventilation duct
通常使用空调管道，必须进行保温隔热。螺旋风道内可粘贴保温材料，表面美观大方。
Central air conditioning pipes are usually used and must be insulated. The spiral air duct can be pasted with thermal insulation materials, and the surface is beautiful and generous.
3、通风管道除灰
3. Air duct ash removal
在一些加工厂和生产线上，粉尘量大，需要专门的除尘设备。螺旋风管可用于缠绕大量的总风管流量。
In some processing plants and production lines, there is a large amount of dust, so special dust removal equipment is required. Spiral duct can be used to wind a large amount of total duct flow.
具体应用条件等领域正在加强，此外，还可以采用防松加固法。这种方法主要是加强对独特管件的开发，主要包括曲折管件、经济管等，以防止通风管在特定应用中移动和放松。
Specific application conditions and other fields are being strengthened. In addition, anti loose reinforcement method can also be used. This method is mainly to strengthen the development of unique pipe fittings, mainly including zigzag pipe fittings and economic pipes, so as to prevent the ventilation pipe from moving and relaxing in specific applications.
风管与离心风机连接时，进风口之间应加软接头。软接头的截面规格应与离心风机的进风口一致。一般软管接头可用白帆布、人造革等原材料制成。管子长度不小于200，松紧度要合适，软塑料软管可以缓冲离心风机的振动。风管与除尘设备、电加热设备等连接前，应在设备安装完成后，根据具体测绘项目的工程图纸进行预制构件及安装。
When the air duct is connected with the centrifugal fan, a soft joint shall be added between the air inlets. The Section specification of the flexible joint shall be consistent with the air inlet of the centrifugal fan. General hose joints can be made of white canvas, artificial leather and other raw materials. The length of the pipe shall not be less than 200, and the tightness shall be appropriate. The soft plastic hose can buffer the vibration of the centrifugal fan. Before connecting the air duct with dust removal equipment, electric heating equipment, etc., the prefabricated components and installation shall be carried out according to the engineering drawings of specific surveying and mapping projects after the equipment installation.
此外，
济南通风管道加工人员提醒您，传统的通风空调工程风管采用水平连接方式，采用扁钢制作成对法兰，铆接在风管的两侧和对面。垫片并用地脚螺栓将它们相互连接。由于材料、机器和工作的限制，管道不太可能加长以减少这种类型的连接。
In addition, Jinan ventilation duct processing personnel remind you that the traditional ventilation and air conditioning engineering air ducts are horizontally connected, and flat steel is used to make paired flanges, which are riveted on both sides and opposite sides of the air ducts. Shim and connect them with foundation bolts. Due to material, machine and work limitations, it is unlikely that the pipe will be lengthened to reduce this type of connection.
通风管道的考虑主要包括通风口、管道、风门、风设备和一些配件。这次镀锌圆法兰主要强调的是通风管道管道和通风管道系统中的风门的操作注意事项：它是风管的识别。风管改造前，其中一项内容是明确的，那就是风管的标高。使用高度调整命令查看时，有时显示的结果会有所不同。这是因为管道和管道的标高是管道的标高。只要管道的高度很高，就将管道视为管道。
Ventilation ducts mainly include vents, ducts, dampers, air equipment and some accessories. The galvanized round flange mainly emphasizes the precautions for the operation of the ventilation duct and the damper in the ventilation duct system: it is the identification of the air duct. Before the reconstruction of air duct, one of the contents is clear, that is, the elevation of air duct. When viewing with the height adjustment command, sometimes the results displayed will be different. This is because the pipe and the elevation of the pipe are the center elevation of the pipe. Pipes are considered pipes as long as they are high.
焊接风管本身采用焊接工艺。经严格检验，可按客户要求组装。多种实用程序（常用卡箍和法兰两种）可以充分保证设备的稳定运行。使用寿命长，占地面积小。镀锌板螺旋风管制造工艺特点和优势安装施工条件：焊接风管排风系统和空调系统通风管的安装一般需要在建筑物屋顶完成，安装场地障碍已清理干净。
Welding process is adopted for welding air duct. After strict inspection, it can be assembled according to customer requirements. A variety of utility programs (commonly used clamp and flange) can fully ensure the stable operation of the equipment. Long service life and small floor area. Manufacturing process characteristics and advantages of galvanized sheet spiral air duct installation and construction conditions: the installation of the exhaust system of the welded air duct and the ventilation pipe of the air conditioning system generally needs to be completed on the roof of the building, and the obstacles in the installation site have been cleared.
The above is the relevant introduction of the problem. I hope it can help you. You can follow our website www.jnqsg COM, for more detailed information, our professional customer service staff will also provide you with good service!
