通風管道生產中常見的2大問題

2 common problems in the production of ventilation ducts

通風管道具有使空氣流通，降低有害氣體濃度的作用，但是由于一些原因，可能導致加工出來的風管有問題。下面我們帶大家詳細了解一下通風管道生產中常見的2點問題以及解決方法。

Ventilation duct can make air flow and reduce the concentration of harmful gas, but for some reasons, it may lead to problems in the air duct. Now let's take a detailed look at 2 common problems in ventilation pipe production and their solutions.

一、風管翹角及彎頭角度不準

1. The angle of the wind pipe and the angle of the elbow is not allowed.

表現：矩形風管兩相對平面、兩端面不平行;折角不平直;對角線不相等;咬口不嚴。

Performance: Rectangular duct two opposite planes, two ends of the plane is not parallel; Angle is not straight; Diagonal is not equal; bite is not strict.

影響：會使風管連接受力不均勻，安裝后的風管不平直，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。

Influence: It will make the connection of air duct uneven, the installation of air duct is not straight, flange gasket is not tight, the system air leakage, resulting in air conditioning load loss, and shorten the service life.

原因：板下料放樣不準確;風管兩兩平行，相對面的板料長度和寬度不相等。

The reason is that the blanking is not accurate, and the length and width of the 22 parallel pipes are not equal.

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，應將風管相對面的兩片板料重合檢驗尺寸準確性。

Measures: When blanking is unfolded, the sheet should be strictly angled, and the length, width and diagonal of each sheet should be checked so that their deviation can be controlled within the allowable range.

二、加工材料未達標

Two, processing materials are not up to standard.

表現：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;風管平面下沉，側面向外凸起，有明顯的變形。

Performance: The surface of the plate is not uniform, the thickness is not uniform, there are obvious indentation, cracks, trachoma, scarring and rust, etc. Air duct plane subsidence, lateral protrusion, obvious deformation.

影響：運轉時風管漏風，空調負荷增加，同時風壽命和性能被影響。

Impact: during operation, air leakage is increased, air conditioning load is increased, and wind life and performance are affected.

原因：材料不合格，不能滿足制作風管的需求。

The reason is that the material is not qualified and can not meet the demand of making air duct.

措施：在使用風管加工設備制作風管前，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 making air duct with air duct processing equipment, we should check the material certificate and material quality certificate as well as appearance thickness to ensure that the material is available.

可見，通風管道生產中經常會遇到加工材料不達標以及風管翹角及彎頭角度不準的現象，因此我們想要生產出高質量的風管，就必須做好充足的事前和操作準備，今天講的大家都記住了嗎？希望能夠給您帶來幫助。

Visible, often encountered in the production of ventilation ducts processing materials do not meet the standards and duct angle and bend angle is not accurate, so we want to produce high-quality duct, we must do a good job in advance and operational preparation, today we all remember? I hope I can help you.
