专注通风管道加工·排烟罩

If there is a problem with the smoke exhaust system of the ventilation duct, it will affect the normal use of the duct. Where should we find the reason after the problem? Let Shandong ventilation pipe processing factory tell you!

1、设计不合理：因在开业装修时预计的就餐人员饱和值低于现今就餐饱和值，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。解决方法：在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。

1. Unreasonable design: because the expected saturation value of dining personnel during opening and decoration is lower than the current dining saturation value, the workload of back kitchen increases, multiple stoves operate at the same time, the original design fan speed is low and the smoke exhaust volume is small, resulting in poor smoke exhaust. Solution: install fan type four leaf or six leaf smoke exhaust fan at the smoke exhaust outlet to improve the smoke exhaust volume, or replace the high wind volume fan.

2、设备陈旧老化：部分厨房设备中的老式排油烟设备排油烟罩老化，导致烟罩漏风，排烟量降低。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(管径约300mm*300mm),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。

2. Old and aging equipment: the old oil fume exhaust equipment in some kitchen equipment has an aging oil fume hood, resulting in air leakage of the hood and reduced smoke exhaust. The aging of the smoke exhaust fan leads to the reduction of the speed and smoke exhaust volume. The oil fume pipes of the old oil fume exhaust equipment are relatively thin (the pipe diameter is about 300mm * 300mm). Due to the accumulation of oil dirt for a long time and inconvenient cleaning, the smoke exhaust effect is also poor.

另外，还有大家可能容易忽略的问题，这也是比较重要的一点，那就是是要加强平时通风管道保养和清洗工作，这也会影响通风管道的排烟工作。

In addition, there are some problems that you may easily ignore, which is also an important point. That is to strengthen the maintenance and cleaning of the ventilation duct at ordinary times, which will also affect the smoke exhaust of the ventilation duct.
