Air is an important part of people's life. Without air, people will feel suffocated and unable to live. Oxygen in the air is also the basic element to maintain people's life. Therefore, it is necessary to keep indoor ventilation to meet people's demand for oxygen, which is also the role of ventilation pipe processing in people's life. But what are the quality problems involved in the process? The following small series of Shandong ventilation pipe processing to introduce it.

通風(fēng)管道是通風(fēng)和空氣調(diào)節(jié)系統(tǒng)的重要組成部分，大部分都是由管道加工設(shè)備（如通風(fēng)管道生產(chǎn)線）制成。但是由于各種各樣的原因，可能導(dǎo)致管道加工設(shè)備加工而成的通風(fēng)管道出現(xiàn)問題。

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

1、加工材料未達(dá)標(biāo)

1. Processing materials not up to standard

①表現(xiàn)：板材表面不平整，厚度不均勻，有明顯的壓痕、裂紋、砂眼和銹蝕等情況；通風(fēng)管道平面下沉，側(cè)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 and rust; the plane of the ventilation pipe is sinking, the side is convex outward, and there is obvious deformation.

②影響：運(yùn)轉(zhuǎn)時通風(fēng)管道漏風(fēng)，空調(diào)負(fù)荷增加，同時風(fēng)壽命和性能被影響。

② Impact: during operation, the air duct leaks, the air conditioning load increases, and the air life and
performance are affected.

③原因：材料不合格，不能滿足制作通風(fēng)管道的需求。

③ Cause: the material is not qualified, can not meet the needs of making ventilation duct.

④措施：在使用通風(fēng)管道加工設(shè)備制作通風(fēng)管道前，要先檢查材料出廠合格證書和材料質(zhì)量證明還有外觀厚度等，保證材料是可用的。

④ Measures: before using the ventilation pipe processing equipment to make the ventilation pipe, it is necessary to check the material factory certificate, material quality certificate and appearance thickness to ensure that the material is available.

2、山東通風(fēng)管道翹角及彎頭角度不準(zhǔn)

2. The warping angle and elbow angle of Shandong ventilation pipeline are not accurate

①表現(xiàn)：矩形通風(fēng)管道兩相對平面、兩端面不平行；折角不平直；對角線不相等；咬口不嚴(yán)。

① Performance: Rectangular Ventilation Duct two relative planes, two end faces are not parallel; inflection angle is not straight; diagonal is not equal; bite is not tight.

②影響：會使通風(fēng)管道連接受力不均勻，安裝后的通風(fēng)管道不平直，法蘭盤墊片不嚴(yán)密，系統(tǒng)漏風(fēng)，造成空調(diào)負(fù)荷損失，并且縮短使用壽命。

② Influence: it will cause uneven stress of ventilation pipe connection, uneven and straight ventilation pipe after installation, loose flange gasket, system air leakage, resulting in air conditioning load loss and shortening service life.

③原因：板下料放樣不準(zhǔn)確；通風(fēng)管道兩兩平行，相對面的板料長度和寬度不相等。

③ Reasons: the layout of plate blanking is not accurate; the ventilation pipes are parallel, and the length and width of the opposite plate are not equal.

④措施：展開下料時，應(yīng)對板料嚴(yán)格角方，對每片板料的長度、寬度以及檢驗(yàn)對角線，使它們的偏差控制在允許范圍內(nèi)；下料后的板料，應(yīng)將通風(fēng)管道相對面的兩片板料重合檢驗(yàn)尺寸準(zhǔn)確性。

④ Measures: during blanking, the sheet metal should be strictly angled, and the length, width and inspection diagonal of each sheet should be controlled within the allowable range; after blanking, the two sheets opposite to the ventilation duct should be overlapped to check the dimensional accuracy.

山東通風(fēng)管道加工的小編的介紹不知道大家有沒有了解到呀？根據(jù)小編說的幾點(diǎn)通風(fēng)管道加工中出現(xiàn)的一些質(zhì)量問題，大家在選購?fù)L(fēng)設(shè)備的時候一定要在這幾個方面留心一下，避免購買到存在質(zhì)量問題的產(chǎn)品，影響后期的使用效果。

Shandong ventilation pipe processing of small series of introduction do not know you have to understand it? According to some quality problems in the process of ventilation pipe processing, we must pay attention to these aspects when purchasing ventilation equipment, so as to avoid purchasing products with quality problems and affecting the later use effect.
