通风管道是工业与民用建筑的通风与空调工程用金属或非金属管道，是为了使空气流通，降低有害气体浓度的一种市政基础设施。 通风管道大部分都是由风管加工设备制成。但是由于各种各样的原因，可能导致加工出来的风管有问题，下面就来了解一下都有哪些问题。

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、加工材料未达标

1、 Substandard processing materials

a表现：板材表面不平整，厚度不均匀，有明显的压痕、裂纹、砂眼、结疤和锈蚀等情况；风管平面下沉，侧面向外凸起，有明显的变形。

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影响：运转时风管漏风，空调负荷增加，同时风管寿命和性能被影响。

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，不能满足制作风管的需求。

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

d措施：在使用风管加工设备制作风管前，要先检查材料出厂合格证书和材料质量证明还有外观厚度等，保证材料是可用的。

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、风管翘角及弯头角度不准

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

a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。

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，法兰盘垫片不严密，系统漏风，造成空调负荷损失，并且缩短使用寿命。

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：板下料放样不准确；风管两两平行，相对面的板料长度和宽度不相等。

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：展开下料时，应对板料严格角方，对每片板料的长度、宽度以及检验对角线，使它们的偏差控制在允许范围内；下料后的板料，应将风管相对面的两片板料重合检验尺寸准确性。

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.

所以要想生产出来的风管实用耐用高质量，就须在风管加工设备操作前后做好充足的事前和操作准备，保证万无一失，减少不必要的损失。

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.
