We should be very familiar with the ventilation duct. We usually see it in the underground garage, in the office building and in the school. The ventilation duct is the nerve element of the ventilation and air conditioning system, and most of it is made of air duct processing equipment. However, due to many reasons, the air duct processing equipment will lead to many problems in the processing of the ventilation duct, such as the following problems.

Ventilation pipe processing

1.禁止風管翹角和彎頭

1. It is forbidden to bend and bend the air duct

(1)原因：當板被布置和布置時，空氣導管成對平行，并且相對的板在長度和寬度上不相等。

(1) Cause: when the plates are arranged and arranged, the air ducts are parallel in pairs and the opposite plates are not equal in length and width.

(2)步驟：打開下料時，應接好板材的邊角，檢查每張板材的長度、寬度和對角線，使其誤差在允許范圍內;下料后，與風管相對的兩塊板材應重疊，以檢查尺寸精度。

(2) Steps: when opening the blanking, the edges and corners of the plates should be connected, and the length, width and diagonal lines of each plate should be checked to make the error within the allowable range; after blanking, the two plates opposite to the air duct should be overlapped to check the dimensional accuracy.

(3)表示兩對矩形風道是三維的，兩個端面不平行;折疊角度不直;對角線不平等;咬的不嚴格。

(3) It means that two pairs of rectangular air ducts are three-dimensional, the two end faces are not parallel, the folding angle is not straight, the diagonal is not equal, and the biting is not strict.

(4)影響：會造成風管連接受力不均勻，安裝后風管不均勻，法蘭墊片松動，系統漏氣，造成空調負荷損失，延長使用壽命。

(4) Influence: it will cause uneven stress of air duct connection, uneven air duct after installation, loose flange gasket, system air leakage, resulting in air conditioning load loss and extending service life.

2.處理數據不符合標準

2. Data processing does not meet the standard

(1)原因：數據不合格，每一步制造風管的要求不嚴格。

(1) Cause: the data is unqualified, and the requirements for each step of manufacturing air duct are not strict.

(2)步驟：在使用濟南通風管道加工設備制造風管之前，需要對出廠合格證、數據質量確認等表面厚度等數據進行反思。以確保數據可用。

(2) Steps: before using Jinan ventilation pipe processing equipment to manufacture air duct, it is necessary to reflect on the surface thickness data such as the factory certificate and data quality confirmation. To ensure that the data is available.

(3)板外不平整，厚度不均勻，有明顯的壓痕、裂紋、砂眼、疤痕、銹蝕等環境;風道三維下沉，前端向外突出，變形明顯。

(3) The outside of the board is not smooth, the thickness is uneven, there are obvious indentation, crack, sand hole, scar, rust and other environment; the air duct sinks in three dimensions, the front end protrudes outward, and the deformation is obvious.

(4)影響：運行中風管泄漏，空調負荷增加，影響風的壽命和性能。

(4) Influence: leakage of air duct during operation, increase of air conditioning load, and impact on service life and performance of wind.
