When installing the ventilation pipe, first find the elevation, drill a hole on the wall with an electric drill, and bury the support frame with the hole reserved for the support; Level and align the assembled pipes and fix them with fixing bolts.

經過比較，如果是安裝通風排煙管道，則通風管道和排煙管道應分開。兩者的通風方向和位置不同。循環空氣的質量比上一個好，所以不能使用相同的風道。一般有圓形和矩形兩種通風管道，如果是圓形管道，則使用平均直徑。

After comparison, if the ventilation and smoke exhaust pipes are installed, the ventilation pipes and smoke exhaust pipes should be separated. The ventilation direction and position of the two are different. The quality of circulating air is better than the previous one, so the same air duct cannot be used. Generally, there are two types of ventilation ducts: circular duct and rectangular duct. If it is circular duct, the average diameter shall be used.

廚房排煙管道存在的問題：

Problems of kitchen smoke exhaust pipe:

1、煙流不易排出

1. The smoke flow is not easy to discharge

煙道中的油漬殘留在煙罩和煙道表面。時間長了會形成油垢。簡單的清潔是無法去除的。這會影響抽油煙機和煙道的使用，并使排煙困難。

The oil stain in the flue remains on the hood and flue surface. Oil dirt will form over time. Simple cleaning cannot be removed. This will affect the use of the range hood and flue, and make it difficult to smoke.

2、極易發生火災

2. Extremely prone to fire

廚房的炊煙在油煙機和油煙機內的氣壓管積油后，當灶具工作時，爐頭的火焰會飛上來，進入油煙機排煙油煙管。很容易在油煙機和管道里面挑起油來，引起火災。

After the kitchen smoke accumulates oil in the range hood and the air pressure pipe in the range hood, when the stove is working, the flame at the stove head will fly up and enter the smoke exhaust pipe of the range hood. It is easy to pick up oil in the range hood and pipes, causing fire.

廚房排煙管清洗方法是什么，如何清洗?

What is the cleaning method of kitchen smoke exhaust pipe and how to clean it?

1、拆卸法：此法是一種綜合有效的清洗方法，但施工難度大，工人數量多，成本較高。

1. Dismantling method: This method is a comprehensive and effective cleaning method, but it is difficult to construct, has a large number of workers, and has high cost.

油煙管清洗方案是：技術人員根據油煙管清洗的實際情況，計算出一段油煙管在一定距離處拆下，然后向兩個方向延伸清洗，確保徹底清洗。清潔，確保清潔質量。

The cleaning plan of the lampblack pipe is: the technician calculates a section of lampblack pipe to be removed at a certain distance according to the actual situation of the lampblack pipe cleaning, and then extends the cleaning in two directions to ensure thorough cleaning. Clean to ensure the cleaning quality.

2、開孔法：這種方法比拆解法容易，成本也比較低，但是清洗效果比較不同。

2. Opening method: This method is easier than disassembly method, and the cost is lower, but the cleaning effect is different.

具體方法是：技術人員計算開孔的間隔距離、位置、大小和數量，通過這些孔在油煙管中清洗油煙管。然后密封每個孔。

The specific method is: technicians calculate the interval distance, position, size and quantity of openings, and clean the oil smoke pipe in the oil smoke pipe through these holes. Then seal each hole.

3、機械設備法：此法操作簡單，難度小，工作量小，成本低，但同時清洗效果也較差，但對于油煙管道的垂直清洗，清洗周期為不到半年時間，這種El Camino清洗無疑是更好的選擇。

3. Mechanical equipment method: This method is simple in operation, small in difficulty, small in workload, and low in cost, but the cleaning effect is also poor at the same time. However, for the vertical cleaning of lampblack pipes, the cleaning cycle is less than half a year. This El Camino cleaning is undoubtedly the best choice.

具體方法是：化油器噴入油煙管后，可延伸油煙管。

The specific method is: after the carburetor is sprayed into the oil fume pipe, it can be extended to the oil fume pipe.
