一、主精东AV视频精东影业视频黄色通风面积不够
I. insufficient ventilation area of main exhaust pipe
根据工程经验，精东AV视频主精东影业视频黄色内风速不能超过15m/s，否则在运行一个时期以后很容易造成精东AV视频系统不通畅。在油烟净化器的运行实践中，大部分案例都是因精东AV视频精东影业视频黄色通风面积不足引起的不通畅，精东影业视频黄色内气体的流速都在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、精东影业视频黄色截面积变小
II. Reduction of Pipeline Section Area
精东AV视频精东影业视频黄色由于要穿过建筑梁而使精东影业视频黄色通风截面积变小，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、排精东影业视频黄色使用后积聚物堆积
3. Accumulation after the use of drainage pipes
精东AV视频精东影业视频黄色在穿过建筑梁或躲避其它设备精东影业视频黄色时，精东AV视频精东影业视频黄色中的一段会低于整体精东AV视频精东影业视频黄色平面，在使用一段时间后，由于油水混合物会积聚在较低的那段精东AV视频精东影业视频黄色中，直接影响精东AV视频通畅。
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、低层精东AV视频不顺畅
4. Smoke exhaust at low level is not smooth
不同楼层的厨房油烟通过同一主精东影业视频黄色排出，离出口近的楼层厨房精东AV视频效果较好，而较低楼层的厨房精东AV视频不通畅。
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.
