排烟管道是近年来很多家庭或酒店餐厅都普遍安装的一种，随着现在生活水平的提高，人们对排烟系统的选择和安装有着更新的认识，那排烟管道不通畅是什么原因导致的呢？
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
油烟机使用一段时间，叶轮、烟道上粘有大量油污，增加叶轮重量，会增加风轮转动动能，电机起动电流会加大。
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.
长期不清洗的油烟机，开机时电流是正常值的3-6倍，这样比较容易烧毁电机，定期清洗油烟机，对电机是一个很好的保护作用，可以延长油烟机的使用寿命。
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、设计不合理
2. Unreasonable design
后厨工作量增加，多台灶同时作业，原设计风机转数低，排烟量小，导致排烟不畅。
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.
在厨房排烟管道安装的排烟口加装风扇式四叶或六叶排烟风机，提高排烟量或更换大风量风机。
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、设备陈旧老化
3. Equipment aging
排烟风机老化导致转速降低，排烟量降低，老式排油烟设备的油烟管道都比较细，因长时间积存油垢又不方便清洗，也同样导致排烟效果不好。
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.
