一、主蜜桃视频在线免费蜜桃成人在线精品视频通风面积不够
I. insufficient ventilation area of main exhaust pipe
根据工程经验，蜜桃视频在线免费主蜜桃成人在线精品视频内风速不能超过15m/s，否则在运行一个时期以后很容易造成蜜桃视频在线免费系统不通畅。在油烟净化器的运行实践中，大部分案例都是因蜜桃视频在线免费蜜桃成人在线精品视频通风面积不足引起的不通畅，蜜桃成人在线精品视频内气体的流速都在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、蜜桃成人在线精品视频截面积变小
II. Reduction of Pipeline Section Area
蜜桃视频在线免费蜜桃成人在线精品视频由于要穿过建筑梁而使蜜桃成人在线精品视频通风截面积变小，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、排蜜桃成人在线精品视频使用后积聚物堆积
3. Accumulation after the use of drainage pipes
蜜桃视频在线免费蜜桃成人在线精品视频在穿过建筑梁或躲避其它设备蜜桃成人在线精品视频时，蜜桃视频在线免费蜜桃成人在线精品视频中的一段会低于整体蜜桃视频在线免费蜜桃成人在线精品视频平面，在使用一段时间后，由于油水混合物会积聚在较低的那段蜜桃视频在线免费蜜桃成人在线精品视频中，直接影响蜜桃视频在线免费通畅。
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、低层蜜桃视频在线免费不顺畅
4. Smoke exhaust at low level is not smooth
不同楼层的厨房油烟通过同一主蜜桃成人在线精品视频排出，离出口近的楼层厨房蜜桃视频在线免费效果较好，而较低楼层的厨房蜜桃视频在线免费不通畅。
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.
