排煙管道是近年來很多家庭或酒店餐廳都普遍安裝的一種，隨著現在生活水平的提高，人們對排煙系統的選擇和安裝有著更新的認識，那排煙管道不通暢是什么原因導致的呢？
In recent years, many families or hotel restaurants are generally installed with smoke exhaust pipe. With the improvement of living standards, people have a new understanding of the selection and installation of smoke exhaust system. What is the reason for the unobstructed smoke exhaust pipe?
1、定期清洗
1. Regular cleaning
油煙機使用一段時間，葉輪、煙道上粘有大量油污，增加葉輪重量，會增加風輪轉動動能，電機起動電流會加大。
When the range hood is used for a period of time, there is a large amount of oil on the impeller and flue. Increasing the weight of the impeller will increase the rotational kinetic energy of the fan, and the starting current of the motor will increase.
長期不清洗的油煙機，開機時電流是正常值的3-6倍，這樣比較容易燒毀電機，定期清洗油煙機，對電機是一個很好的保護作用，可以延長油煙機的使用壽命。
If the range hood is not cleaned for a long time, the current is 3-6 times of the normal value when it is started, so it is easy to burn the motor. Cleaning the range hood regularly is a good protection for the motor and can prolong the service life of the range hood.

2、設計不合理
2. Unreasonable design
后廚工作量增加，多臺灶同時作業，原設計風機轉數低，排煙量小，導致排煙不暢。
The workload of the kitchen is increasing, and many stoves are working at the same time. The original design has low fan speed and small smoke exhaust volume, which leads to poor smoke exhaust.
在廚房排煙管道安裝的排煙口加裝風扇式四葉或六葉排煙風機，提高排煙量或更換大風量風機。
Install fan type four or six leaf smoke exhaust fan at the smoke outlet of the kitchen smoke exhaust pipe to increase the smoke exhaust volume or replace the high wind fan.
3、設備陳舊老化
3. Equipment aging
排煙風機老化導致轉速降低，排煙量降低，老式排油煙設備的油煙管道都比較細，因長時間積存油垢又不方便清洗，也同樣導致排煙效果不好。
The aging of exhaust fan leads to the reduction of speed and exhaust volume. The oil fume pipes of old-fashioned exhaust equipment are relatively thin. Due to long-term accumulation of oil dirt and inconvenient cleaning, the exhaust effect is also poor.
