关于油烟管道排烟不畅有哪些原因?

油烟机在使用一段时间，油烟机叶轮、排烟风机烟道上将粘有大量的油污，增加了叶轮的重量，这样势必增加了风轮转动动能，使电机起动电流加大。

权威机构曾经做过测试：长期未清洗的油烟机，在开机时的电流是正常值的3-6倍，这样很容易烧毁电机，所以定期清洗油烟机，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。油污粘住电机转轴，加大了磨擦力，使电机负荷加大——费电。轴流风机油污长期积累，发生氧化形成酸性物质，对油烟机进行腐蚀，生锈，加速油烟机老化。

油污长期积累在油烟机内部和烟道内部，还将形成火灾隐患。叶轮、烟道上的油污增加了粘性，使排气不畅通，增加了油烟在厨房空间上的扩散，危害人们健康。

What are the reasons for the poor smoke exhaust from the lampblack pipeline?

For a period of time, there will be a lot of oil pollution in the impeller and exhaust fan flue, which will increase the weight of the impeller. This will inevitably increase the rotational kinetic energy of the wind wheel and increase the starting current of the motor.

Authoritative organizations have done testing: the long-term clean lampblack machine, when starting the current is 3-6 times the normal value, so it is easy to burn the motor, so regular cleaning lampblack machine, motor is a good protection, can extend the service life of lampblack machine. Oil stain sticks to the motor shaft, increases the friction force, and increases the load of the motor - electricity consumption. The oil pollution of axial fan accumulates for a long time, and oxidizes to form acidic substance, which corrodes and rusts the lampblack machine and accelerates its aging.

Oil pollution accumulates in the inside of the hood and flue for a long time, which will also cause fire hazards. Oil pollution in impeller and flue increases stickiness, makes exhaust unobstructed, increases the spread of oil fume in kitchen space, and endangers people's health.
