通風管道是工業(yè)與民用建筑的通風與空調工程用金屬或非金屬管道，是為了使空氣流通，降低有害氣體濃度的一種市政基礎設施。 通風管道大部分都是由風管加工設備制成。但是由于各種各樣的原因，可能導致加工出來的風管有問題，下面就來了解一下都有哪些問題。

Ventilation pipe is a kind of metal or nonmetal pipe used in ventilation and air conditioning engineering of industrial and civil buildings, which is a municipal infrastructure to make the air circulate and reduce the concentration of harmful gases. Most of the ventilation pipes are made of air pipe processing equipment. However, due to a variety of reasons, there may be problems with the processed air duct. Let's find out what the problems are.

一、加工材料未達標

1、 Substandard processing materials

a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。

A performance: uneven surface, uneven thickness, obvious indentation, crack, sand hole, scar and corrosion, etc; The plane of the air duct sinks, and the side of the air duct protrudes outwards with obvious deformation.

b影響：運轉時風管漏風，空調負荷增加，同時風管壽命和性能被影響。

B effect: the air duct leaks during operation, the air conditioning load increases, and the service life and performance of the air duct are affected.

c原因：材料不合格，不能滿足制作風管的需求。

C reason: the material is unqualified, which can not meet the needs of the production of air duct.

d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。

D measures: before using the air duct processing equipment to make the air duct, the factory certificate, material quality certificate and appearance thickness of the material should be checked to ensure that the material is available.

二、風管翹角及彎頭角度不準

2、 The warping angle and elbow angle of air duct are not accurate

a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。

A performance: two relative planes and two end planes of rectangular duct are not parallel; The angle is not straight; The diagonals are not equal; The bite is not tight.

b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(tǒng)漏風，造成空調負荷損失，并且縮短使用壽命。

B influence: it will cause uneven force on the air duct connection, uneven air duct after installation, loose flange gasket, air leakage in the system, resulting in air conditioning load loss and shortening service life.

c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。

C reason: inaccurate setting out of plate cutting; The air ducts are parallel, and the length and width of the sheet metal on the opposite side are not equal.

d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。

D 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 air duct shall be overlapped to check the dimensional accuracy.

所以要想生產出來的風管實用耐用高質量，就須在風管加工設備操作前后做好充足的事前和操作準備，保證萬無一失，減少不必要的損失。

Therefore, in order to make the air duct practical, durable and high quality, we must make sufficient preparation before and after the operation of the air duct processing equipment, so as to ensure the safety and reduce unnecessary losses.
