The standard of living is getting better and better, so whether it's a hotel or a small restaurant on the street, the business is becoming more and more prosperous. However, the business is good, but the attendant trouble also comes: the smoke exhaust of range hood and range hood pipeline in kitchen equipment is not smooth, resulting in the poor back kitchen environment and seriously affecting the health of employees. We summarized some reasons for the poor smoke exhaust effect of back kitchen kitchen.

1、首先规划不合理：因在开业装修时估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，原规划风机转数低，排烟量小，导致排烟不畅。解决办法：在排烟口加装风扇式四叶或六叶排烟风机，进步排烟量;或替换大风量风机。

1. First of all, the planning is unreasonable: because the estimated saturation value of diners 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 originally planned 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 fan.

2、然后设备陈旧老化：部分厨房设备中的旧式排油烟设备排油烟罩老化，导致烟罩漏风，排烟量下降;排烟风机老化导致转速下降，排烟量下降，旧式排油烟设备的油烟管道都比较细(管径约300mm*300mm),因长期积存油垢又不便利清洗，也同样导致排烟效果不好。

2. Then, the equipment is old and aging: the exhaust hood of the old oil fume exhaust equipment in some kitchen equipment is aging, resulting in air leakage of the hood and reduction of smoke exhaust; The aging of smoke exhaust fan leads to the decrease of rotating speed and smoke exhaust volume. The oil fume pipes of old oil fume exhaust equipment are relatively thin (pipe diameter is about 300mm * 300mm). Due to the long-term accumulation of oil dirt and inconvenient cleaning, it also leads to poor smoke exhaust effect.

解决办法：没其他好办法，查查终究哪的问题Z严峻，查查烟罩、烟道是否漏风，能够缓和一些，假设还不行，一般风机的问题Z大，那有或许就得换了，假设说下降费用的话，排油烟罩能够保留。

Solution: there is no other good way. Check whether the Problem z is serious after all. Check whether the smoke hood and flue leak. It can be alleviated. If not, the Problem z of general fans may have to be replaced. If the cost is reduced, the oil fume hood can be retained.

3、终究未守时清洗：油烟机在运用一段时间，油烟机叶轮、烟道大将粘有许多的油污，增加了叶轮的分量，这样必然增加了风轮滚动动能，使电机起动电流加大。机构从前做过测试：长期未清洗的油烟机，在开机时的电流是正常值的3-6倍，这样很简略焚毁电机，所以守时清洗油烟机，对电机是一个很好的维护效果，能够延伸油烟机的运用寿数。油污粘住电机转轴，加大了磨擦力，使电机负荷加大——费电。

3. After all, it is not cleaned on time: after the range hood has been used for a period of time, there will be a lot of oil stains on the impeller and flue of the range hood, which will increase the component of the impeller, which will inevitably increase the rolling kinetic energy of the wind wheel and increase the starting current of the motor. The organization has done tests before: the current of the range hood that has not been cleaned for a long time is 3-6 times of the normal value when it is started up, so it is easy to burn the motor. Therefore, timely cleaning of the range hood is a good maintenance effect for the motor and can extend the service life of the range hood. Oil stains stick to the motor shaft, increasing the friction force and increasing the motor load - electricity consumption.

济南酒店厨房排烟罩清洗的好处：

Benefits of cleaning the kitchen smoke hood of Jinan Hotel:

1.酒店大型油烟机排风涡轮定期清洗可提高排风效果，因为大型风机的千叶涡轮叶片本身间隙就很小，一旦沾满油腻排烟效果会大打折扣。

1. Regular cleaning of the exhaust turbine of the hotel's large range hood can improve the exhaust effect, because the clearance of the thousand blade turbine blade itself of the large fan is very small, and the smoke exhaust effect will be greatly reduced once it is greasy.

2.油烟净化器定期清洗，因为油烟净化器作为排烟系统的重要部分，它是集中油腻Z多的地方。净化器清洗干净不但利于厨房排烟流畅，更能解除消防隐患。

2. The oil fume purifier shall be cleaned regularly, because the oil fume purifier, as an important part of the smoke exhaust system, is a place with a lot of grease. Cleaning the purifier is not only conducive to smooth smoke exhaust in the kitchen, but also can eliminate fire hazards.

3.排烟主管道，特别是主排烟管水平线低处就是油烟屯积的地方。由于饭店厨房设备的油污所引发的火灾事故已经不胜枚举，希望广大业主不可掉以轻心。

3. The main smoke exhaust pipe, especially the lower part of the horizontal line of the main smoke exhaust pipe, is the place where oil smoke accumulates. The fire accidents caused by the oil pollution of hotel kitchen equipment have been numerous. I hope the owners can't take it lightly.
