目前山東通風管道的生產廠家很多，各公司生產的通風管道在技術和質量上都存在一定的差異。也正因為如此，我們應該重視通風管道運行時產生的噪音問題，這是衡量通風管道的一個重要指標。而且噪音問題不僅和材料有很大關系，還和施工有很大關系。

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.

當安裝不銹鋼螺旋管道，如果不注意正確的安裝方法，后果會非常嚴重。通風管道一旦安裝調試，發現里面有噪音問題，我們再調試會比較困難。也正因為如此，在安裝過程中注意正確的操作步驟是非常重要的。

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.

接下來，當處于對噪音控制要求較高的場合時，要注意選擇低噪音的通風設備。

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

不同類型的通風設備在相同的風量和風壓下。其實要注意的是，翼葉片的離心通風設備噪音比較小，前葉片的離心通風設備噪音會比較大。那么，其實要注意的是通風管道內空氣的流速問題。

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.

通風管道主要是在風管白鐵皮上鍍上一層鋅，對鐵皮起到保護的作用。鋅鍍層經鈍化處理、染色或涂覆護光劑后，能顯著提高其防護性和裝飾性。

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.

只有好好保養風管，才能延長“壽命”。而保養方式，當然是定時做好清潔工作，對此有效的風管的清洗方式有：

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：用類似有手握式的真空吸污管來操作。用刷子直接接觸通風管道管道內壁以清除污物。這種方法需要風管有較大的檢修孔使操作的人員能夠得到，但這種方法可能漏掉一局部塵土和污物，因為風管不能形成完全的負壓條件。

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、動力洗刷：用氣動或者電動的毛刷將臟污刷動，然后污物用和氣體沖洗相同的方法和方向被吸到真空收集器中。這種方法要求盡可能的小心不至于破壞保溫材料的外表。

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.

鑒于以上因素，就一點而言，其實要注意根據實際安裝環境選擇相對合適的通風設備。當然相關的維護清洗工作也為您講解了，您對此有不明白的地方可以隨時來我們網站http://www.xyphw.com進行咨詢！

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.xyphw.com Consult!
