隨著社會的發(fā)展，很多家庭住宅、酒店廚房都會使用通風管道，所以，通風管道加工安裝顯得非常重要，一旦出現(xiàn)不合理，就會造成反味現(xiàn)象，對家居生活造成影響。廚房排煙管道的設計和安裝不合理，往往會造成廚房排煙不通暢，直接影響油煙凈化器的使用，其主要原因有以下幾種：

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

就是設計不合理：因在開業(yè)裝修時預計的就餐人員飽和值低于現(xiàn)今就餐飽和值，后廚工作量增加，多臺灶同時作業(yè)，原設計風機轉數(shù)低，排煙量小，導致排煙不暢。解決方法：在排煙口加裝風扇式四葉或六葉排煙風機，提高排煙量，或更換大風量風機;

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;

再有就是設備陳舊老化：部分廚房設備中的老式排油煙設備排油煙罩老化，導致煙罩漏風，排煙量降低。排煙風機老化導致轉速降低，排煙量降低，老式排油煙設備的油煙管道都比較細(管徑約300mm*300mm),因長時間積存油垢又不方便清洗，也同樣導致排煙效果不好。還有一點就是特別重要的是要加強平時通風管道保養(yǎng)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.

鍍鋅風管安裝簡單，現(xiàn)場制做方便，與土建工程配合緊密，能適合非常復雜的凈化通風工程。產品多用于大型、寫字樓、地鐵站、大型、現(xiàn)代化工廠的消防排煙、空調通風、排塵通風等。原材料直接從源頭進貨，保證鍍鋅板的質量及鍍鋅卷板的優(yōu)勢，可根據(jù)廣大用戶的不同需要生產加工各種型。

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.

通風管道是通風和空氣調節(jié)系統(tǒng)的重要組成部分，大部分都是由管道加工設備（如通風管道生產線）制成。但是由于各種各樣的原因，可能導致風管加工設備加工而成的通風管道出現(xiàn)問題。

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、加工材料未達標

1. Substandard processing materials

①表現(xiàn)：板材表面不平整，厚度不均勻，有明顯的壓痕、裂紋、砂眼和銹蝕等情況；通風管道平面下沉，側面向外凸起，有明顯的變形。

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影響：運轉時通風管道漏風，空調負荷增加，同時風壽命和性能被影響。

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，不能滿足制作通風管道的需求。

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

④措施：在使用通風管道加工設備制作通風管道前，要先檢查材料出廠合格證書和材料質量證明還有外觀厚度等，保證材料是可用的。

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、通風管道翹角及彎頭角度不準

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

①表現(xiàn)：矩形通風管道兩相對平面、兩端面不平行；折角不平直；對角線不相等；咬口不嚴。

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影響：會使通風管道連接受力不均勻，安裝后的通風管道不平直，法蘭盤墊片不嚴密，系統(tǒng)漏風，造成空調負荷損失，并且縮短使用壽命。

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：板下料放樣不準確；通風管道兩兩平行，相對面的板料長度和寬度不相等。

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：展開下料時，應對板料嚴格角方，對每片板料的長度、寬度以及檢驗對角線，使它們的偏差控制在允許范圍內；下料后的板料，應將通風管道相對面的兩片板料重合檢驗尺寸準確性。

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.
