专注通风管道加工·排烟罩

我们在许多住宅建筑和办公建筑中都可以看到通风管道的身影，但大家不知道的是通风管道在加工的时候是会产生很多问题的，这些问题令很多工作人员都很苦恼，下面我们来了解一下济南通风管道加工时经常会出现的问题及解决措施。一起来看看吧。

We can see the presence of ventilation ducts in many residential buildings and office buildings, but what we don't know is that there will be many problems in the processing of ventilation ducts, which annoy many workers. Let's learn about the problems and solutions that often occur in the processing of ventilation ducts in Jinan. Let's have a look.

1、通风管道翘角及弯头角度不准

1. The warping angle and elbow angle of the ventilation pipe are not allowed

表现：折角不平直;矩形通风管道两相对平面、两端面不平行;咬口不严;对角线不相等。

Performance: the bending angle is not straight; Two opposite planes and two end surfaces of rectangular ventilation duct are not parallel; Loose bite; The diagonals are not equal.

原因：通风管道两两平行，相对面的板料长度和宽度不相等;板下料放样不准确。

Cause: the ventilation duct is parallel in two and the length and width of the opposite sheet are not equal; The setting out of plate blanking is inaccurate.

影响：会使通风管道连接受力不均匀，安装后的通风管道不平直，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。

Impact: it will cause uneven stress of ventilation pipe connection, uneven ventilation pipe after installation, loose flange gasket, air leakage of the system, loss of air conditioning load, and shorten service life.

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，应将通风管道相对面的两片板料重合检验尺寸准确性。

Measures: during blanking, strictly control the angle of the sheet, check the length, width and diagonal of each sheet, and control their deviation within the allowable range; After blanking, the two sheets on the opposite side of the ventilation duct shall be overlapped to check the dimensional accuracy.

2、通风管道加工材料未达标

2. The processing materials of ventilation pipes are not up to standard

表现：通风管道平面下沉，侧面向外凸起，有明显的变形;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。

Performance: the plane of the ventilation duct sinks, the side bulges outward, and there is obvious deformation; The surface of the plate is uneven, the thickness is uneven, and there are obvious indentation, crack, sand hole, scar and rust.

原因：材料不合格，不能满足制作通风管道的需求。

Reason: the materials are unqualified and cannot meet the needs of manufacturing ventilation ducts.

影响：运转时通风管道漏风，空调负荷增加，同时风寿命和性能被影响。

Impact: during operation, the ventilation duct leaks air, the air conditioning load increases, and the air life and performance are affected.

措施：在使用通风管道加工设备制作通风管道前，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。

Measures: before using the ventilation pipe processing equipment to make the ventilation pipe, the factory certificate of material, the material quality certificate and the appearance thickness should be checked first to ensure that the material is available.
