我們在許多住宅建筑和辦公建筑中都可以看到通風管道的身影，但大家不知道的是通風管道在加工的時候是會產生很多問題的，這些問題令很多工作人員都很苦惱，下面我們來了解一下濟南通風管道加工時經常會出現的問題及解決措施。一起來看看吧。

We can see the presence of ventilation ducts in many residential buildings and office buildings, but what we don't know is that there will be many problems in the processing of ventilation ducts, which annoy many workers. Let's learn about the problems and solutions that often occur in the processing of ventilation ducts in Jinan. Let's have a look.

1、通風管道翹角及彎頭角度不準

1. The warping angle and elbow angle of the ventilation pipe are not allowed

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

Performance: the bending angle is not straight; Two opposite planes and two end surfaces of rectangular ventilation duct are not parallel; Loose bite; The diagonals are not equal.

原因：通風管道兩兩平行，相對面的板料長度和寬度不相等;板下料放樣不準確。

Cause: the ventilation duct is parallel in two and the length and width of the opposite sheet are not equal; The setting out of plate blanking is inaccurate.

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。

Impact: it will cause uneven stress of ventilation pipe connection, uneven ventilation pipe after installation, loose flange gasket, air leakage of the system, loss of air conditioning load, and shorten service life.

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。

Measures: during blanking, strictly control the angle of the sheet, check the length, width and diagonal of each sheet, and 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.

2、通風管道加工材料未達標

2. The processing materials of ventilation pipes are not up to standard

表現：通風管道平面下沉，側面向外凸起，有明顯的變形;板材表面不平整，厚度不均勻，有明顯的壓痕、裂紋、砂眼、結疤和銹蝕等情況。

Performance: the plane of the ventilation duct sinks, the side bulges outward, and there is obvious deformation; The surface of the plate is uneven, the thickness is uneven, and there are obvious indentation, crack, sand hole, scar and rust.

原因：材料不合格，不能滿足制作通風管道的需求。

Reason: the materials are unqualified and cannot meet the needs of manufacturing ventilation ducts.

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。

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

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。

Measures: before using the ventilation pipe processing equipment to make the ventilation pipe, the factory certificate of material, the material quality certificate and the appearance thickness should be checked first to ensure that the material is available.

這兩個問題的解決措施已經告訴大家了，希望大家可以應用到實踐過程中去，如果近期有需要安裝通風管道、加工通風管道或者購買通風管道的大家可以了解一下我們的公司的產品，有什么需求和問題可以隨時聯系我們http://www.www.qa48.com。
