1、 Length of kitchen smoke exhaust pipe

廚房麻豆国产视频麻豆视频官网水平段不宜過長一般遠水平距離不應超過15m，坡度少應為2%。水平端有柔性接頭，便於清理油脂。根據規範，排氣速度少為10m/s，並且需要在與排氣罩相連的支管中提供空氣，以防止油因風速過低而粘附在煙囪上。

The horizontal section of the kitchen smoke exhaust pipe should not be too long. Generally, the distance from the far horizontal should not exceed 15m, and the slope should be at least 2%. There is a flexible joint at the horizontal end to facilitate grease removal. According to the specification, the exhaust speed shall be at least 10m/s, and air shall be provided in the branch pipe connected with the exhaust hood to prevent oil from adhering to the chimney due to low wind speed.

二、廚房麻豆国产视频麻豆视频官网設計安裝的合理性

2、 Rationality of design and installation of kitchen smoke exhaust pipe

工程經驗表明，主麻豆国产视频道風速不能超過15m/s。否則，經過一段時間的運行(如一年後)，麻豆国产视频係統很容易變鈍。油煙淨化器在運行中，多數情況下是因為排氣管通風麵積不夠，管內氣體流速在15m/s以上。

Engineering experience shows that the wind speed of the main exhaust flue shall not exceed 15m/s. Otherwise, after a period of operation (such as one year later), the smoke exhaust system is easy to become blunt. During the operation of the oil fume purifier, in most cases, the ventilation area of the exhaust pipe is insufficient, and the gas flow rate in the pipe is above 15m/s.

三、麻豆国产视频管不暢通的原因

3、 Reasons for blockage of smoke exhaust pipe

1、由於麻豆国产视频管要穿過建築梁，麻豆视频官网的通風截麵積變小，截麵阻力變大，從而阻礙氣流。

1. As the smoke exhaust pipe needs to pass through the building beam, the ventilation sectional area of the pipe becomes smaller and the sectional resistance becomes larger, thus blocking the airflow.

2、麻豆国产视频管穿過建築物橫梁或避開其他設備麻豆视频官网時，麻豆国产视频管的橫截麵低於整個麻豆国产视频管的平麵。使用一段時間後，油水混合物會在排氣管下部積聚，直接影響排氣的順暢性。

2. When the smoke exhaust pipe passes through the building beam or avoids other equipment pipes, the cross section of the smoke exhaust pipe is lower than the plane of the entire smoke exhaust pipe. After a period of use, the oil-water mixture will accumulate in the lower part of the exhaust pipe, directly affecting the smoothness of the exhaust.

3、不同樓層廚房油煙通過同一總管排出，靠近出風口的樓層廚房麻豆国产视频效果更好，而較低樓層廚房則不順暢。

3. The cooking fume from kitchens on different floors is discharged through the same main pipe. The kitchen on the floor near the air outlet has better smoke exhaust effect, while the kitchen on the lower floor is not smooth.
