空氣中的氧氣也是維持人們生活的基本元素，因此應(yīng)始終保持室內(nèi)通風(fēng)，以滿足人們對氧氣的需求。這也是通風(fēng)管道加工對人們生活的影響，下面我們來看看濟(jì)南通風(fēng)管道加工可能會存在兩個質(zhì)量問題。

Oxygen in the air is also the basic element to maintain people's life, so indoor ventilation should always be maintained to meet people's demand for oxygen. This is also the impact of ventilation pipe processing on people's lives. Now let's take a look at two quality problems that may exist in ventilation pipe processing in Jinan.

1、加工資料未達(dá)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 uneven, the thickness is uneven, and there are significant indentation, cracks, sand holes and rust; The plane of the ventilation pipe sinks, and the side faces outward, with obvious deformation.

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

② Impact: the air leakage of the ventilation duct during operation, the air conditioning load is added, and the 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 unqualified, and the requirements for manufacturing ventilation ducts are 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 Method: Before using the air duct processing equipment to manufacture the air duct, the factory certificate, quality certificate and appearance thickness of the data shall be checked to ensure that the data are available.

2、通風(fēng)管道翹角及彎頭視點禁絕：

2. The warping angle of the ventilation pipe and the view point of the 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(yán)。

① Performance: two opposite planes and two end faces of rectangular ventilation duct are not parallel; The corner is not straight; Diagonal lines are 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(yán)密，體系漏風(fēng)，形成空調(diào)負(fù)荷損失，并且縮短使用壽命。

② Effect: It will cause uneven stress on the connection of ventilation pipes, uneven ventilation pipes behind the device, untight flange gaskets, air leakage of the system, resulting in air conditioning load loss and shortened 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 Cause: The blanking and setting out of plates are strictly prohibited; The two sides of the ventilation pipe are parallel, and the length and width of the sheet on the opposite side are not equal.

④辦法：打開下料時，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 Method: When the blanking is opened, the angle of the sheet shall be strictly controlled, and the length, width and diagonal of each sheet shall be checked to control their deviation within the allowable range; After blanking, the two sheets on the opposite side of the ventilation duct shall be overlapped to check the dimensional accuracy.

通風(fēng)管道加工可能會存在兩個質(zhì)量問題就到這里了，小編這里提醒您，在加工之前盡量去多多進(jìn)行了解，做好相關(guān)的準(zhǔn)備工作，才能在使用中減少更多問題出現(xiàn)。關(guān)注我們http://www.pvcbox.cn，了解更多事項！
