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

一，禁止風管翹角和彎頭，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。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。

1、 When the boards are arranged and arranged, the air ducts are parallel in pairs, and the length and width of the opposite boards are not equal. Steps: when opening the blanking, the edges and corners of the plate should be connected, and the length, width and diagonal 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.

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。這種情況往往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。

It means that two pairs of rectangular air ducts are three-dimensional and the two end faces are not parallel; The folding angle is not straight; Diagonal inequality; The bite is not strict. This kind of situation often leads to uneven force of air duct connection, uneven air duct after installation, loose flange gasket, air leakage of the system, resulting in air conditioning load loss and prolonging service life.

二，處理數據不符合標準，數據不合格，每一步制造風管的要求不嚴格。

2、 The processing data is not up to standard, the data is not up to standard, and the requirements for each step of air duct manufacturing are not strict.

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。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。影響運行中風管泄漏，空調負荷增加，影響風的壽命和性能。

Before using Jinan ventilation duct processing equipment to manufacture air duct, it is necessary to reflect on the surface thickness data such as factory certificate and data quality confirmation. To ensure that the data is available. There are obvious indentation, crack, sand hole, scar, corrosion and other environment; The air duct sinks in three dimensions, the front end protrudes outwards, and the deformation is obvious. The air duct leakage will affect the operation, the air conditioning load will increase, and the service life and performance of the air conditioner will be affected.
