通风管道出现排烟不畅通的原因！

随着社会的发展，很多家庭住宅、酒店厨房都会使用通风管道，所以，通风管道加工安装显得非常重要，一旦出现不合理，就会造成反味现象，对家居生活造成影响。厨房排烟管道的设计和安装不合理，往往会造成厨房排烟不通畅，直接影响油烟净化器的使用，其主要原因有以下几种：

With the development of society, many families, hotels and kitchens will use ventilation pipes. Therefore, the processing and installation of ventilation pipes is very important. Once there is an unreasonable situation, it will cause the odor phenomenon and affect the home life. The unreasonable design and installation of kitchen exhaust pipe will often cause the kitchen exhaust is not smooth, which directly affects the use of fume purifier

就是设计不合理：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;

The reason is that the design is unreasonable: because the expected saturation value of dining staff is lower than the current saturation value when opening and decorating, the workload of kitchen is increased, and many stoves operate at the same time, the original design fan speed is low, and the smoke exhaust volume is small, which leads to poor smoke exhaust. Solution: install fan type four leaf or six leaf smoke exhaust fan at the smoke exhaust outlet to increase the smoke exhaust volume, or replace the high wind fan;

再有就是设备陈旧老化：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。还有一点就是特别重要的是要加强平时通风管道保养和清洗工作。

Then there is the aging of equipment: some of the kitchen equipment in the old-fashioned exhaust hood aging exhaust hood, resulting in hood air leakage, reduced smoke. The aging of exhaust fan leads to the decrease of speed and exhaust volume. The oil fume pipes of old exhaust equipment are relatively thin (about 300 mm * 300 mm in diameter). Due to the accumulation of oil dirt for a long time and inconvenient cleaning, the exhaust effect is also poor. Another point is that it is particularly important to strengthen the usual maintenance and cleaning of ventilation pipes.

镀锌风管安装简单，现场制做方便，与土建工程配合紧密，能适合非常复杂的净化通风工程。产品多用于大型、写字楼、地铁站、大型、现代化工厂的消防排烟、空调通风、排尘通风等。原材料直接从源头进货，保证镀锌板的质量及镀锌卷板的优势，可根据广大用户的不同需要生产加工各种型。

Galvanized air duct is easy to install, convenient to make on site, and closely cooperate with civil engineering, which is suitable for very complex purification and ventilation engineering. The products are mostly used for fire control and smoke exhaust, air conditioning and ventilation, dust exhaust and ventilation in large shopping malls, office buildings, subway stations, large supermarkets and modern chemical plants. Raw materials are purchased directly from the source to ensure the quality of galvanized sheet and the price advantage of galvanized coil. Various types of galvanized sheet can be produced and processed according to the different needs of users.

通风管道是通风和空气调节系统的重要组成部分，大部分都是由管道加工设备（如通风管道生产线）制成。但是由于各种各样的原因，可能导致风管加工设备加工而成的通风管道出现问题。

Ventilation pipe is an important part of ventilation and air conditioning system, most of which are made of pipe processing equipment (such as ventilation pipe production line). However, due to a variety of reasons, it may lead to problems in the air duct processing equipment.

1、加工材料未达标

1. Substandard processing materials

①表现：板材表面不平整，厚度不均匀，有明显的压痕、裂纹、砂眼和锈蚀等情况；通风管道平面下沉，侧面向外凸起，有明显的变形。

① Performance: the surface of the plate is not smooth, the thickness is not uniform, there are obvious indentation, cracks, sand holes and corrosion; the plane of the ventilation pipe sinks, the side protrudes outward, there is obvious deformation.

②影响：运转时通风管道漏风，空调负荷增加，同时风寿命和性能被影响。

② Impact: the air leakage of ventilation duct during operation, the air conditioning load increases, and the air life and performance are affected.

③原因：材料不合格，不能满足制作通风管道的需求。

③ Reason: the material is unqualified, which can't meet the demand of making ventilation pipe.

④措施：在使用通风管道加工设备制作通风管道前，要先检查材料出厂合格证书和材料质量证明还有外观厚度等，保证材料是可用的。

④ Measures: before using the ventilation pipe processing equipment to make the ventilation pipe, the factory certificate, material quality certificate and appearance thickness of the material should be checked to ensure that the material is available.

2、通风管道翘角及弯头角度不准

2. The warping angle and elbow angle of ventilation pipe are not accurate

①表现：矩形通风管道两相对平面、两端面不平行；折角不平直；对角线不相等；咬口不严。

① Performance: two relative planes and two ends of rectangular ventilation duct are not parallel; the angle is not straight; the diagonal is not equal; the bite is not tight.

②影响：会使通风管道连接受力不均匀，安装后的通风管道不平直，法兰盘垫片不严密，系统漏风，造成空调负荷损失，并且缩短使用寿命。

② Influence: it will make the ventilation pipe connection stress uneven, after the installation of the ventilation pipe is not straight, flange gasket is not tight, system air leakage, resulting in air conditioning load loss, and shorten the service life.

③原因：板下料放样不准确；通风管道两两平行，相对面的板料长度和宽度不相等。

③ Causes: the setting out of plate cutting is not accurate; the ventilation pipes are parallel, and the length and width of plate on the opposite side are not equal.

④措施：展开下料时，应对板料严格角方，对每片板料的长度、宽度以及检验对角线，使它们的偏差控制在允许范围内；下料后的板料，应将通风管道相对面的两片板料重合检验尺寸准确性。

④ Measures: when unfolding and blanking, the angle of sheet metal shall be strictly square, and the length, width and diagonal of each sheet metal shall be inspected, so as to control their deviation within the allowable range; after blanking, the two sheets on the opposite side of the ventilation pipe shall be overlapped, and the dimensional accuracy shall be inspected.
