The installation position of the exhaust hood in Jinan hotel kitchen is closely related to the length of the pipe. Many family owners for aesthetic, will let the installation master will pull the pipe very long. In fact, in this way, it is easy to make the oil fumes in the pipeline can not be discharged.

然后，再進行安裝通風管道。通風管道安裝首先找好標高，用電鉆打墻洞，配合預(yù)留的支架孔洞埋設(shè)吊托支架;將組裝好的風管找平、找正，再用緊固螺栓固定。

Then, install the ventilation pipe. In the installation of ventilation pipe, the elevation shall be found first, the wall hole shall be drilled with electric drill, and the hanging support shall be embedded with the reserved support hole; the assembled air pipe shall be leveled and aligned, and then fixed with fastening bolts.

比較后，如果是通風排煙管道的安裝，通風管道和排煙管道應(yīng)該分開，兩者的通風方向和地點是不同的，流通的空氣質(zhì)量前者優(yōu)于后者，所以不能使用同一個管道。通風管一般有兩種圓形和矩形，如果是圓形風管就按平均直徑。

After comparison, if it is the installation of ventilation and smoke exhaust pipe, the ventilation pipe and smoke exhaust pipe should be separated. The ventilation direction and location of the two are different. The air quality of the former is better than that of the latter, so the same pipe cannot be used. There are generally two kinds of circular and rectangular ventilation pipes. If it is circular, the average diameter of the ventilation pipe is calculated.

一、煙流不易排出

1、 The smoke is not easily discharged

Exhaust hood of Jinan hotel kitchen

煙道內(nèi)的油漬殘留在煙機和煙道表面上，時間久了會形成油垢，簡單的清洗是處理不掉的，這樣會影響油煙機、煙道的使用，使煙流不易排除。

The oil stains in the flue remain on the surface of the range hood and flue. After a long time, it will form oil dirt, which can not be disposed of by simple cleaning. This will affect the use of the range hood and flue, and make it difficult to eliminate the smoke flow.

二、極易發(fā)生火災(zāi)

2、 Fire prone

廚房的抽油煙脫排罩內(nèi)及罩上的空壓管道內(nèi)積累油污后，在炒灶工作時， 爐頭的火焰上飛，進入煙罩及排油煙管道內(nèi)，極易引起罩內(nèi)和管道內(nèi)的油污燃燒，引發(fā)火災(zāi)。

When cooking, the flame at the end of the stove will fly up and enter into the hood and exhaust pipe, which will easily cause the oil burning in the hood and pipe and cause fire.
