一、主香蕉视频下载网址香蕉视频黄版APP通风面积不够
I. insufficient ventilation area of main exhaust pipe
根据工程经验，香蕉视频下载网址主香蕉视频黄版APP内风速不能超过15m/s，否则在运行一个时期以后很容易造成香蕉视频下载网址系统不通畅。在油烟净化器的运行实践中，大部分案例都是因香蕉视频下载网址香蕉视频黄版APP通风面积不足引起的不通畅，香蕉视频黄版APP内气体的流速都在15m/s以上。
According to engineering experience, the wind speed in the main smoke exhaust pipe should not exceed 15 m/s, otherwise the smoke exhaust system will be blocked easily after a period of operation. In the operation practice of lampblack purifier, most cases are caused by insufficient ventilation area of exhaust pipe, and the gas flow rate in the pipe is above 15m/s.
二、香蕉视频黄版APP截面积变小
II. Reduction of Pipeline Section Area
香蕉视频下载网址香蕉视频黄版APP由于要穿过建筑梁而使香蕉视频黄版APP通风截面积变小，截面上阻力增加，造成气流不通畅。
The ventilation cross-section area of the smoke exhaust pipeline is reduced and the resistance on the cross-section is increased due to the passage of the smoke exhaust pipeline through the building beams, resulting in the airflow obstruction.
三、排香蕉视频黄版APP使用后积聚物堆积
3. Accumulation after the use of drainage pipes
香蕉视频下载网址香蕉视频黄版APP在穿过建筑梁或躲避其它设备香蕉视频黄版APP时，香蕉视频下载网址香蕉视频黄版APP中的一段会低于整体香蕉视频下载网址香蕉视频黄版APP平面，在使用一段时间后，由于油水混合物会积聚在较低的那段香蕉视频下载网址香蕉视频黄版APP中，直接影响香蕉视频下载网址通畅。
When the smoke exhaust pipe passes through the building beam or evades other equipment pipelines, one section of the smoke exhaust pipe will be lower than the overall smoke exhaust pipe plane. After using for a period of time, the oil-water mixture will accumulate in the lower section of the smoke exhaust pipe, which directly affects the smooth smoke exhaust.
四、低层香蕉视频下载网址不顺畅
4. Smoke exhaust at low level is not smooth
不同楼层的厨房油烟通过同一主香蕉视频黄版APP排出，离出口近的楼层厨房香蕉视频下载网址效果较好，而较低楼层的厨房香蕉视频下载网址不通畅。
The kitchen fumes of different floors are discharged through the same main pipe. The smoke exhaust effect of the kitchen on the floor near the exit is better, while the smoke exhaust of the kitchen on the lower floor is not smooth.
