In our life, we often have various opportunities to contact pipeline products, especially ventilation pipes. Ventilation pipes are essential in entertainment places, hotels and even factories.

山東通風管道加工通風設備我們都很熟悉，通風管道是連接風機、空氣處理設備和進風口的管道，是通風設備的重要組成部分。設計通風管道時，應注意通風管道中的阻力，設應盡可能減小阻力。

We are all familiar with the ventilation equipment of Shandong ventilation pipe processing. The ventilation pipe is the pipe connecting the fan, air handling equipment and air inlet. It is an important part of the ventilation equipment. When designing the ventilation duct, pay attention to the resistance in the ventilation duct and reduce the resistance as much as possible.

自通風管道問世以來，由于其自身的特點和低價席卷了整個市場，受到許多制造商的歡迎。在使用中，要學會該學會維護和清潔通風管道，以便更好地發揮自己的作用。

Since the air duct came out, it has swept the whole market due to its own characteristics and low price, and has been welcomed by many manufacturers. In use, we should learn how to maintain and clean the ventilation duct, so as to better play our role.

1.通風管道加工所用材料應具有低導熱性、保溫性、耐腐蝕性和耐火性。

1. The materials used in the processing of ventilation pipes shall have low thermal conductivity, thermal insulation, corrosion resistance and fire resistance.

2.通風管道設計不應過長，在可能的條件下；直徑要粗，樣式要圓。

2. The design of ventilation duct shall not be too long, if possible; The diameter should be thick and the style should be round.

3.支管半徑不小于主管半徑的1/2-1/3，便于通風管加工。

3. The radius of the branch pipe shall not be less than 1 / 2-1 / 3 of the radius of the main pipe, which is convenient for the processing of the ventilation pipe.

4.設計通風管道時，彎曲角度應盡可能彎曲。

4. When designing the ventilation duct, the bending angle shall be as curved as possible.

5.設計通風管道時，彎頭應盡可能少，兩個彎頭之間的距離應較大。當兩彎頭之間的距離為管徑的3倍時，阻力增加約80%。如果是5倍，只會增加30%。

5. When designing the ventilation duct, the elbows should be as few as possible, and the distance between the two elbows should be large. When the distance between two elbows is 3 times of the pipe diameter, the resistance increases by about 80%. If it is five times, it will only increase by 30%.

6.盡量直立或傾斜，并設置清洗口。連接部分應緊密氣密，易于維修。

6. Try to be upright or inclined, and set up a cleaning port. The connecting part shall be tight and airtight and easy to maintain.
