廚房排煙風管安裝加工中，有什么需要注意的？
What should be noticed during the installation and processing of kitchen smoke exhaust duct?
1、來說說，每家的廚房里都有煙，可是在知道其中還有主副管道之分嗎?主管道貫穿整個樓體。還有而副管道是相對獨立的，但是它以一道帶孔的隔板與主管道隔開，還有上下則由樓板封住。
1. First of all, there is smoke in every kitchen, but do you know whether there are main and auxiliary pipes? The main pipe runs through the whole building. In addition, the auxiliary pipe is relatively independent, but it is separated from the main pipe by a perforated partition, and the upper and lower parts are sealed by the floor.
2、一般家里的油煙會先到副管道里，這個時候要做一個緩存，然后再通過隔板上的孔進入主管道，但是這樣可保證每戶的油煙是隔離開來的，不會串煙。
2. Generally, the lampblack in the house will go to the auxiliary pipe first. At this time, a buffer should be made, and then it enters the main pipe through the hole on the partition. However, this can ensure that the lampblack in each household is isolated and will not smoke.
3、接下來說說，主副管道必須同時存在。但是一些業主家出現倒煙或是串煙現象很可能是由于裝修時錯誤地把排煙管和主管道相連，這樣是為了節省空間拆掉了副管道。
3. Next, the main and auxiliary pipelines must exist at the same time. However, the phenomenon of smoke pouring or smoke stringing in some owners may be due to the wrong connection between the smoke exhaust pipe and the main pipe during decoration, so that the auxiliary pipe is removed to save space.
4、如果直接連接主管道，還有由于其向上的吸力很大，這樣可以比喻為“拔火罐效應”還有，一旦氣壓比較低，這樣就可能把別家的油煙壓到自家來。而副管道則有很好的緩存作用，所以不能拆除。
4. If it is directly connected to the main pipe, it can be compared to the "cupping effect" due to its large upward suction. In addition, once the air pressure is low, it may press the oil smoke from other homes to their own homes. The secondary pipe has a good cache function, so it cannot be removed.
