Air is very important to people's life. We can't live without air. Oxygen in the air is also the basic element to maintain people's lives. Therefore, indoor ventilation should always be maintained to meet people's demand for oxygen. This is also the influence of ventilation pipe processing on people's life. But what are the quality problems in the process of processing? Let's follow Shandong ventilation pipe processing manufacturers to understand it.

1、加工資料未達標(biāo)：

1. Processing data not up to standard:

①表現(xiàn)：板材外表不平整，厚度不均勻，有顯著的壓痕、裂紋、砂眼和銹蝕等情況;通風(fēng)管道平面下沉，旁邊面向外凸起，有顯著的變形。

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

②影響：工作時通風(fēng)管道漏風(fēng)，空調(diào)負荷添加，同時風(fēng)壽命和性能被影響。

② Impact: air leakage in ventilation duct, air conditioning load increase, and air life and performance are affected.

③原因：資料不合格，不能滿意制造通風(fēng)管道的需求。

③ Cause: the data is not qualified, and the requirement of manufacturing ventilation duct is not satisfied.

④辦法：在使用通風(fēng)管道加工設(shè)備制造通風(fēng)管道前，要先查看資料出廠合格證書和資料質(zhì)量證明還有外觀厚度等，確保資料是可用的。

④ Methods: before using the ventilation pipe processing equipment to manufacture the ventilation pipe, check the factory certificate, quality certificate and appearance thickness of the materials to ensure that the materials are available.

2、山東通風(fēng)管道翹角及彎頭視點禁絕：

2. Shandong ventilation pipe warping angle and elbow are forbidden

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。

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(fēng)管道連接受力不均勻，裝置后的通風(fēng)管道不平直，法蘭盤墊片不嚴密，體系漏風(fēng)，形成空調(diào)負荷損失，并且縮短使用壽命。

② Influence: it will make the ventilation pipe connection stress uneven, the ventilation pipe after the device is not straight, the flange gasket is not tight, the system air leakage, resulting in air conditioning load loss, and shorten the service life.

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

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

④辦法：打開下料時，應(yīng)對板料嚴格角方，對每片板料的長度、寬度以及查驗對角線，使它們的偏差控制在答應(yīng)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查驗尺寸準(zhǔn)確性。

④ Methods: when opening the blanking, the angle of the sheet should be strictly square, and the length, width and diagonal of each sheet should be checked, so that their deviation can be controlled within the allowable range; after blanking, the two sheets on the opposite side of the ventilation pipe should be overlapped to check the size accuracy.
