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(fēng)管道加工通風(fēng)設(shè)備我們都很熟悉，通風(fēng)管道是連接風(fēng)機(jī)、空氣處理設(shè)備和進(jìn)風(fēng)口的管道，是通風(fēng)設(shè)備的重要組成部分。設(shè)計(jì)通風(fēng)管道時(shí)，應(yīng)注意通風(fēng)管道中的阻力，設(shè)應(yīng)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(fēng)管道問(wèn)世以來(lái)，由于其自身的特點(diǎn)和低價(jià)席卷了整個(gè)市場(chǎng)，受到許多制造商的歡迎。在使用中，要學(xué)會(huì)該學(xué)會(huì)維護(hù)和清潔通風(fēng)管道，以便更好地發(fā)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(fēng)管道加工所用材料應(yīng)具有低導(dǎo)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(fēng)管道設(shè)計(jì)不應(yīng)過(guò)長(zhǎng)，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(fēng)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(shè)計(jì)通風(fēng)管道時(shí)，彎曲角度應(yīng)盡可能彎曲。

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

5.設(shè)計(jì)通風(fēng)管道時(shí)，彎頭應(yīng)盡可能少，兩個(gè)彎頭之間的距離應(yīng)較大。當(dāng)兩彎頭之間的距離為管徑的3倍時(shí)，阻力增加約80%。如果是5倍，只會(huì)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(shè)置清洗口。連接部分應(yīng)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.
