Ventilation duct is a kind of municipal infrastructure, which can maintain indoor air circulation and reduce harmful gases. They are an important part of the air conditioning system. The air duct is made by the air duct processing equipment, but there will be many problems in the process of air duct processing, such as warping, bending and the problem of processing data not up to standard. Let's talk about the relevant content below.

1、嚴禁翹曲、彎曲風管

1. Warping and bending of air ducts are strictly prohibited

原因：面板排列時，風道成對平行，相對面板的長寬不相等。

Reason: when the panels are arranged, the air ducts are parallel in pairs, and the length and width of the relative panels are not equal.

步驟：開料時，應將板材的角部連接起來，并檢查每張板材的長度、寬度和對角線，使誤差在允許范圍內(nèi)；下料后，風管對面的兩片應重疊，檢查尺寸精度。

Step: when cutting, connect the corners of the plates, and check the length, width and diagonal of each plate to make the error within the allowable range; After blanking, the two pieces opposite the air duct should be overlapped to check the dimensional accuracy.

表示兩對矩形風道是三維的，兩端面不平行；折角不直；對角線沒有嚴格咬合。

Indicates that the two pairs of rectangular air ducts are three-dimensional, and the two ends are not parallel; The angle is not straight; Diagonal is not strictly occluded.

影響：會造成風管受力不均，安裝后風管不均勻，法蘭墊片松動，系統(tǒng)漏風，造成空調負荷損失，延長使用壽命。

Impact: it will cause uneven stress on the air duct, uneven air duct after installation, loose flange gasket, air leakage of the system, resulting in air conditioning load loss and extended service life.

2.處理數(shù)據(jù)不達標

2. The processing data is not up to standard

原因：資料不合格，各工序風管制造要求不嚴格。

Cause: the data are unqualified, and the manufacturing requirements of air duct in each process are not strict.

步驟：在使用通風管加工設備制造風管之前，需要對工廠合格證、數(shù)據(jù)質量確認、表面厚度等數(shù)據(jù)進行反思。確保數(shù)據(jù)可用性。

Step: before using the ventilation pipe processing equipment to manufacture the ventilation pipe, it is necessary to reflect on the factory certificate, data quality confirmation, surface thickness and other data. Ensure data availability.

板外不平整，厚度不均，有明顯的壓痕、裂紋、起泡、傷痕、銹蝕等環(huán)境；風道在三維空間下沉，前端向外凸出，變形明顯。

The outside of the board is uneven, uneven in thickness, and there are obvious indentation, crack, blister, scar, rust and other environments; The air duct sinks in three-dimensional space, the front end protrudes outward, and the deformation is obvious.

影響：山東通風管道加工人員提醒，運行時風管泄漏，空調負荷增大，影響風的壽命和性能。

Impact: Shandong ventilation duct processing personnel reminded that the air duct leakage during operation, the air conditioning load increases, affecting the life and performance of the air.
