厂家为了提高通风管道加工技术，需要不断的面对不同的类型以及不同的质量的产品。改进产品的加工工艺对我们大有好处。只有不断改进整体加工技术，我们才能有更好的质量保证，这是我们今后更好地使用产品的保证。你真的应该注意这一点，毕竟它真的关系到我们未来的使用。
In order to improve the ventilation pipe processing technology, manufacturers need to constantly face different types and different quality products. It is of great benefit to us to improve the processing technology of our products. Only by constantly improving the overall processing technology, can we have better quality assurance, which is the guarantee of better use of our products in the future. You should really pay attention to this, after all, it really matters to our future use.
通风管道系统的工作噪声一般来源于：风管的振动，具体表现在以下几个方面。由于风管数据为镀锌板或金属材料，施工时应严格按照施工验收规范选择钢板厚度和施工工艺，如风管制造误差、平直度、风管加固、支吊架选择和制造设备等。在施工阶段，出风口不应尽可能靠近设备。电风扇的前后长度应尽可能超过5米。
The working noise of ventilation duct system generally comes from the vibration of air duct, which is shown in the following aspects. Since the data of air duct is galvanized sheet or metal material, the steel plate thickness and construction technology should be selected strictly according to the construction acceptance specification, such as air duct manufacturing error, straightness, duct reinforcement, support and hanger selection and manufacturing equipment. In the construction stage, the air outlet should not be as close to the equipment as possible. The front and rear length of the electric fan should be more than 5 meters as far as possible.
通风管道加工以下是一些经验。
The following are some experiences in the processing of ventilation ducts.
1.螺旋风管的拐角应小化。
1. The corner of spiral duct should be minimized.
2、软接头设备规范，防止软帆布松发式阻力和风噪。
2. Soft joint equipment specification, to prevent soft canvas loose resistance and wind noise.
3.螺旋风管风机叶轮系统动平衡调整合理正常，正负波动不超过5线。
3. The dynamic balance adjustment of the impeller system of spiral duct fan is reasonable and normal, and the positive and negative fluctuation is not more than 5 lines.
4、控制出风口和回风区间，防止空气对流自激现象和小流通空间。
4. Control the air outlet and return air area to prevent air convection self excitation phenomenon and small circulation space.
5.悬架应配备一个弹簧悬架的全职连接器，以减少工作期间由扭转引起的跳动或公共频率。
5. The suspension shall be equipped with a full-time connector of spring suspension to reduce runout or common frequency caused by torsion during operation.
通风管道连接原理：
Ventilation pipe connection principle:
以焊接为主要连接方式的管道，应设置足够数量的法兰连接;以螺纹为主要连接方式的连接管道，应设置足够数量的活接头。
For pipes with welding as the main connection mode, sufficient flange connection shall be set; for connecting pipes with thread as main connection mode, sufficient number of movable joints shall be set.
通风管道安装及处理系统的支撑原则：管道不应直接支撑在有阀门部件的设备上，应单独设置支架或吊架。管道焊缝位置应在施工方便或受力较小的地方，焊缝不应位于支架处，距离不应小于200 mm
The support principle of ventilation pipe installation and treatment system: the pipe should not be directly supported on the equipment with valve components, but should be separately set with support or hanger. The position of pipe weld should be in the place where construction is convenient or the stress is small. The welding seam should not be located at the support, and the distance should not be less than 200 mm

通风管道加工面对不同的含尘气体有不同的性质，所以净化的分段处理应该不同。在通风管道处理系统的布局中，一定确保整个系统的泄漏量很小，并且在吸尘口有足够的空气量。通风管道处理系统的布置应减少阻力。圆形风管强度大，材料消耗少，但加工工艺复杂，占用空间大。不锈钢风管易于布置和加工，应用广泛。
There are different properties of different dust containing gases in the ventilation duct processing, so the segmented treatment of purification should be different. In the layout of the ventilation duct treatment system, make sure that the leakage of the whole system is small and there is enough air at the dust suction port. The arrangement of ventilation duct treatment system should reduce resistance. Circular air duct has high strength and less material consumption, but its processing technology is complex and takes up a lot of space. Stainless steel air duct is easy to arrange and process, so it is widely used.
