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

1、加工資料未達標

1. Processing data not up to standard

(1)表現：板材外表不平整，厚度不均勻，有明顯的壓痕、裂紋、砂眼、結疤和銹蝕等狀況;風管平面下沉，旁邊面向外凸起，有明顯的變形。

(1) Performance: the surface of the board is not smooth, the thickness is not uniform, there are obvious indentation, cracks, sand holes, scab and rust, etc.; the plane of the air duct sinks, the side faces to the outside, and has obvious deformation.

(2)影響：工作時風管漏風，空調負荷增加，同時風壽數和性能被影響。

(2) Impact: air leakage in the air duct, air conditioning load increases, and the number of air life and performance are affected.

(3)原因：資料不合格，不能滿意制造風管的需求。

(3) Cause: the data is not qualified, and the requirement of manufacturing air duct is not satisfied.

(4)辦法：在使用風管加工設備制造風管前，要先檢查資料出廠合格證書和資料質量證明還有外觀厚度等，確保資料是可用的。

(4) Method: before using the air duct processing equipment to manufacture the air duct, we should first check the data factory certificate, data quality certificate and appearance thickness to ensure that the data is available.

2、風管翹角及彎頭角度不準

2. Air duct warping angle and elbow angle are not accurate

(1)表現：矩形風管兩相對平面、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 end faces of rectangular air duct are not parallel; inflection angle is not straight; diagonal line is not equal; bite is not tight.


 

 

(2)影響：會使風管連接受力不均勻，安裝后的風管不平直，法蘭盤墊片不緊密，系統漏風，造成空調負荷損失，而且縮短使用壽數。

(2) Influence: it will make the air duct connection stress uneven, the air duct after installation is not straight, the flange gasket is not tight, the 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;風管兩兩平行，相對面的板料長度和寬度不相等。

(3) Reasons: the layout of plate cutting is not accurate; the air duct is parallel to each other, and the sheet metal length and width on the opposite side are not equal.

(4)辦法：展開下料時，應對板料嚴厲角方，對每片板料的長度、寬度以及查驗對角線，使它們的偏差控制在答應范圍內;下料后的板料，應將風管相對面的兩片板料重合查驗尺寸準確性。

(4) Methods: when blanking, the sheet metal should be strictly angled, and the length, width and diagonal lines of each sheet should be checked to make their deviation within the allowable range; after blanking, the two sheets opposite to the air duct should be overlapped to check the dimensional accuracy.
