目前山东通风管道的生产厂家很多，各公司生产的通风管道在技术和质量上都存在一定的差异。也正因为如此，我们应该重视通风管道运行时产生的噪音问题，这是衡量通风管道的一个重要指标。而且噪音问题不仅和材料有很大关系，还和施工有很大关系。

At present, there are many manufacturers of ventilation pipes in Shandong, and there are certain differences in the technology and quality of ventilation pipes produced by various companies. Because of this, we should pay attention to the noise generated during the operation of the ventilation duct, which is an important indicator to measure the ventilation duct. Moreover, noise is not only related to materials, but also to construction.

当安装不锈钢螺旋管道，如果不注意正确的安装方法，后果会非常严重。通风管道一旦安装调试，发现里面有噪音问题，我们再调试会比较困难。也正因为如此，在安装过程中注意正确的操作步骤是非常重要的。

When installing stainless steel spiral pipes, if you do not pay attention to the correct installation method, the consequences will be very serious. Once the ventilation pipe is installed and debugged, it is found that there is a noise problem in it. It will be difficult for us to debug again. Because of this, it is very important to pay attention to the correct operation steps during the installation process.

接下来，当处于对噪音控制要求较高的场合时，要注意选择低噪音的通风设备。

Next, when the noise control requirements are high, pay attention to the selection of low-noise ventilation equipment.

不同类型的通风设备在相同的风量和风压下。其实要注意的是，翼叶片的离心通风设备噪音比较小，前叶片的离心通风设备噪音会比较大。那么，其实要注意的是通风管道内空气的流速问题。

Different types of ventilation equipment are under the same air volume and pressure. In fact, it should be noted that the noise of the centrifugal ventilation equipment of the wing blade is relatively small, and the noise of the centrifugal ventilation equipment of the front blade is relatively large. In fact, we should pay attention to the air velocity in the ventilation duct.

通风管道主要是在风管白铁皮上镀上一层锌，对铁皮起到保护的作用。锌镀层经钝化处理、染色或涂覆护光剂后，能显著提高其防护性和装饰性。

The ventilation duct is mainly coated with zinc on the white iron sheet of the air duct to protect the iron sheet. The protective and decorative properties of zinc coating can be significantly improved after passivation treatment, dyeing or coating of protective agent.

只有好好保养风管，才能延长“寿命”。而保养方式，当然是定时做好清洁工作，对此有效的风管的清洗方式有：

Only by properly maintaining the air duct can the "service life" be extended. The maintenance method, of course, is to do a good job of cleaning at regular intervals. The effective cleaning methods for air duct include:

A、真空吸污：用类似有手握式的真空吸污管来操作。用刷子直接接触通风管道管道内壁以清除污物。这种方法需要风管有较大的检修孔使操作的人员能够得到，但这种方法可能漏掉一局部尘土和污物，因为风管不能形成完全的负压条件。

A. Vacuum suction: operate with a vacuum suction pipe similar to a hand-held one. Use a brush to directly contact the inner wall of the ventilation duct to remove dirt. This method requires the air duct to have a large manhole so that the operators can get it, but this method may leak a part of dust and dirt, because the air duct cannot form a complete negative pressure condition.

B、动力洗刷：用气动或者电动的毛刷将脏污刷动，然后污物用和气体冲洗相同的方法和方向被吸到真空收集器中。这种方法要求尽可能的小心不至于破坏保温材料的外表。

B. Power washing: use pneumatic or electric brush to brush the dirt, and then the dirt is sucked into the vacuum collector in the same way and direction as gas washing. This method requires as much care as possible not to damage the appearance of the insulation material.

鉴于以上因素，就一点而言，其实要注意根据实际安装环境选择相对合适的通风设备。当然相关的维护清洗工作也为您讲解了，您对此有不明白的地方可以随时来我们网站http://www.jntfgd.com进行咨询！

In view of the above factors, in fact, we should pay attention to selecting relatively appropriate ventilation equipment according to the actual installation environment. Of course, the relevant maintenance and cleaning work has also been explained to you. If you don't understand this, you can come to our website at any time http://www.jntfgd.com Consult!
