通风管道加工是通风和空气调节系统的重要组成部分，大部分都是由风管加工设备(如风管生产线)制成。可是因为各种各样的原因，可能导致风管加工设备加工而成的风管出现问题。
Ventilation duct processing is an important part of ventilation and air conditioning system, most of which are made by duct processing equipment (such as duct production line). However, due to various reasons, it may lead to problems in the air duct processed by air duct processing equipment.
1、加工资料未达标
1. Processing data not up to standard
(1)表现：板材外表不平整，厚度不均匀，有明显的压痕、裂纹、砂眼、结疤和锈蚀等状况;风管平面下沉，旁边面向外凸起，有明显的变形。
(1) Performance: the surface of the board is not smooth, the thickness is not uniform, there are obvious indentation, cracks, sand holes, scab and rust, etc.; the plane of the air duct sinks, the side faces to the outside, and has obvious deformation.
(2)影响：工作时风管漏风，空调负荷增加，同时风寿数和性能被影响。
(2) Impact: air leakage in the air duct, air conditioning load increases, and the number of air life and performance are affected.
(3)原因：资料不合格，不能满意制造风管的需求。
(3) Cause: the data is not qualified, and the requirement of manufacturing air duct is not satisfied.
(4)办法：在使用风管加工设备制造风管前，要先检查资料出厂合格证书和资料质量证明还有外观厚度等，确保资料是可用的。
(4) Method: before using the air duct processing equipment to manufacture the air duct, we should first check the data factory certificate, data quality certificate and appearance thickness to ensure that the data is available.
2、风管翘角及弯头角度不准
2. Air duct warping angle and elbow angle are not accurate
(1)表现：矩形风管两相对平面、两端面不平行;折角不平直;对角线不相等;咬口不严。
(1) Performance: two relative planes and two end faces of rectangular air duct are not parallel; inflection angle is not straight; diagonal line is not equal; bite is not tight.
(2)影响：会使风管连接受力不均匀，安装后的风管不平直，法兰盘垫片不紧密，系统漏风，造成空调负荷损失，而且缩短使用寿数。
(2) Influence: it will make the air duct connection stress uneven, the air duct after installation is not straight, the flange gasket is not tight, the system air leakage, resulting in air conditioning load loss, and shorten the service life.
(3)原因：板下料放样不准确;风管两两平行，相对面的板料长度和宽度不相等。
(3) Reasons: the layout of plate cutting is not accurate; the air duct is parallel to each other, and the sheet metal length and width on the opposite side are not equal.
(4)办法：展开下料时，应对板料严厉角方，对每片板料的长度、宽度以及查验对角线，使它们的偏差控制在答应范围内;下料后的板料，应将风管相对面的两片板料重合查验尺寸准确性。
(4) Methods: when blanking, the sheet metal should be strictly angled, and the length, width and diagonal lines of each sheet should be checked to make their deviation within the allowable range; after blanking, the two sheets opposite to the air duct should be overlapped to check the dimensional accuracy.
