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(yán)禁翹曲、彎曲風(fēng)管

1. Warping and bending of air ducts are strictly prohibited

原因：面板排列時(shí)，風(fēng)道成對(duì)平行，相對(duì)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(shí)，應(yīng)將板材的角部連接起來，并檢查每張板材的長度、寬度和對(duì)角線，使誤差在允許范圍內(nèi)；下料后，風(fēng)管對(duì)面的兩片應(yīng)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(duì)矩形風(fēng)道是三維的，兩端面不平行；折角不直；對(duì)角線沒有嚴(yán)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(huì)造成風(fēng)管受力不均，安裝后風(fēng)管不均勻，法蘭墊片松動(dòng)，系統(tǒng)漏風(fēng)，造成空調(diào)負(fù)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(dá)標(biāo)

2. The processing data is not up to standard

原因：資料不合格，各工序風(fēng)管制造要求不嚴(yán)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(fēng)管加工設(shè)備制造風(fēng)管之前，需要對(duì)工廠合格證、數(shù)據(jù)質(zhì)量確認(rèn)、表面厚度等數(shù)據(jù)進(jìn)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(fēng)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(fēng)管道加工人員提醒，運(yùn)行時(shí)風(fēng)管泄漏，空調(diào)負(fù)荷增大，影響風(fēng)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.
