風管主要是指空調系統的通風管道,它常常被忽視但它卻是空調系統的重要組成部分，那么，我們在安裝風管時會遇到哪些常見問題呢?比如風管安裝的不平不直等問題，下面
山東通風管道廠家對其進行分析。
Air duct mainly refers to the ventilation duct of the central air conditioning system, which is often ignored but is an important part of the air conditioning system. What common problems will we encounter when installing air duct? For example, the installation of air duct is not straight. The following is the analysis of Shandong ventilation duct manufacturer.
1、風管安裝的不平，不直
1. The air duct is installed unevenly and not straight
影響：使偏移，法蘭的接口間距不均勻，漏風量過大，外形不美觀。
Influence: the center is offset, the flange interface spacing is uneven, the air leakage is too large, and the appearance is not beautiful.
原因：支架，吊架預留的位置和標高不一致，間距不等，風管受力不均而產生扭曲或彎曲，矩形風管的平整度及法蘭對角線長超差，法蘭與風管軸線不垂直，法蘭互換性，平整度差，螺栓間距大，螺母擰的松緊度不一致。
Cause: The reserved position and elevation of the support and hanger are inconsistent, the spacing is different, the air duct is distorted or bent due to uneven stress, the flatness of the rectangular air duct and the length of the flange diagonal are out of tolerance, the flange is not perpendicular to the central axis of the air duct, the flange interchangeability, the flatness is poor, the bolt spacing is large, and the tightness of the nut is inconsistent.
2、風管安裝的方法不妥
2. Improper installation method of air duct
影響：風管擺動，支架間距不等，保溫風管出現冷橋，降低風管的使用壽命，不美觀，冷熱量損失加大。
Impact: the air duct swings, the bracket spacing is not equal, the insulation air duct has a cold bridge, which reduces the service life of the air duct, is not beautiful, and the loss of cold and heat is increased.
原因：整個風管無固定點，吊桿直接吊在風管的法蘭上，保溫的矩形風管直接和托架，吊桿接觸風管安裝中的問題與形成原因。
Cause: The whole air duct has no fixed point, the suspender is directly hung on the flange of the air duct, the insulated rectangular air duct is directly connected with the bracket, and the suspender contacts the problems and causes in the installation of the air duct.
3、風管的密封墊片安裝及風管，管件等的連接不符合要求
3. The installation of sealing gasket of air duct and the connection of air duct and pipe fittings do not meet the requirements
影響：將出現法蘭連接處跑風漏氣，噪聲變大，冷熱量損耗變大。
Impact: there will be air leakage at the flange connection, the noise will increase, and the cooling and heat loss will increase.
原因：法蘭墊片材質不符合要求，法蘭墊片厚度不夠，因而影響彈性及緊固程度，法蘭墊片凸入風管內，法蘭周邊的螺栓松緊程度不一致。
Cause: The material of flange gasket does not meet the requirements, and the thickness of flange gasket is not enough, which affects the elasticity and tightness. The flange gasket protrudes into the air duct, and the tightness of bolts around the flange is inconsistent.
4、穿越屋面的風管無防雨和穩固措施
4. The air duct crossing the roof has no rain-proof and stability measures
影響：風管與屋面穿越處漏水，滲水，風管穿越屋面處不穩固，下雨后雨水易漏入，滲入房內，室外風力較大時，風管不穩固也易損壞屋面。
Impact: water leakage and seepage at the crossing between the air duct and the roof. The air duct crossing the roof is unstable. Rainwater is easy to leak into the room after rain. When the outdoor wind is strong, the air duct is unstable and easy to damage the roof.
原因：風管與屋面無防雨罩，風管穿越屋面后無拉索或支架固定風管安裝中的問題與形成原因。
Cause: There is no rain cover between the air duct and the roof, and there is no cable or bracket to fix the air duct after the air duct passes through the roof.
The knowledge of air duct installation will be introduced here. You should be careful in the construction process. If you want to know more about decoration, you can pay attention to our website http://www.euio.com.cn ！
