Air is an important part of people's life. Without air, people will feel suffocated and unable to live. The oxygen in the air is also the basic element to maintain people's life. Therefore, we should always maintain indoor ventilation to meet people's demand for oxygen, which is also the role of ventilation pipe processing in people's life. But what quality problems will be involved in the processing process? Now Jinan qiangshun to introduce it.

通風管道是通風和空氣調節系統的重要組成部分，大部分都是由管道加工設備制成。但是由于各種各樣的原因，可能導致管道加工設備加工而成的通風管道出現問題。

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

1、加工材料未達標

1. Substandard processing materials

①表現：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；通風管道平面下沉，側面向外凸起，有明顯的變形。

① Performance: the surface of the plate is not smooth, the thickness is not uniform, there are obvious indentation, cracks, sand holes and corrosion; the plane of the ventilation pipe sinks, the side protrudes outward, there is obvious deformation.

②影響：運轉時通風管道漏風，空調負荷增加，同時風壽命和性能被影響。

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

③原因：材料不合格，不能滿足制作通風管道的需求。

③ Reason: the material is unqualified, which can't meet the demand of making ventilation pipe.

④措施：在使用通風管道加工設備制作通風管道前，要先檢查材料出廠合格證書和材料質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, the factory certificate, material quality certificate and appearance thickness of the material should be checked to ensure that the material is available.

2、通風管道翹角及彎頭角度不準

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

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

① Performance: two relative planes and two ends of rectangular ventilation duct are not parallel; the angle is not straight; the diagonal is not equal; the bite is not tight.

②影響：會使通風管道連接受力不均勻，安裝后的通風管道不平直，法蘭盤墊片不嚴密，系統漏風，造成空調負荷損失，并且縮短使用壽命。

② Influence: it will make the ventilation pipe connection stress uneven, after the installation of the ventilation pipe is not straight, flange gasket is not tight, 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；通風管道兩兩平行，相對面的板料長度和寬度不相等。

③ Causes: the setting out of plate cutting is not accurate; the ventilation pipes are parallel, and the length and width of plate on the opposite side are not equal.

④措施：展開下料時，應對板料嚴格角方，對每片板料的長度、寬度以及檢驗對角線，使它們的偏差控制在允許范圍內；下料后的板料，應將通風管道相對面的兩片板料重合檢驗尺寸準確性。

④ Measures: when unfolding and blanking, the angle of sheet metal shall be strictly square, and the length, width and diagonal of each sheet metal shall be inspected, so as to control their deviation within the allowable range; after blanking, the two sheets on the opposite side of the ventilation pipe shall be overlapped, and the dimensional accuracy shall be inspected.
