专注通风管道加工·排烟罩

Air is an important part of people's life. Without air, people will feel suffocated and unable to live. Oxygen in the air is also the basic element to maintain people's life. Therefore, it is necessary to keep indoor ventilation to meet people's demand for oxygen, which is also the role of ventilation pipe processing in people's life. But what are the quality problems involved in the process? The following small series of Shandong ventilation pipe processing to introduce it.

通风管道是通风和空气调节系统的重要组成部分，大部分都是由管道加工设备（如通风管道生产线）制成。但是由于各种各样的原因，可能导致管道加工设备加工而成的通风管道出现问题。

Ventilation duct is an important part of ventilation and air conditioning system, most of which are made by pipe processing equipment (such as ventilation pipe production line). However, due to a variety of reasons, it may lead to problems in the ventilation pipes processed by pipeline processing equipment.

1、加工材料未达标

1. Processing materials not up to standard

①表现：板材表面不平整，厚度不均匀，有明显的压痕、裂纹、砂眼和锈蚀等情况；通风管道平面下沉，侧面向外凸起，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 and rust; the plane of the ventilation pipe is sinking, the side is convex outward, and there is obvious deformation.

②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。

② Impact: during operation, the air duct leaks, the air conditioning load increases, and the air life and
performance are affected.

③原因：材料不合格，不能满足制作通风管道的需求。

③ Cause: the material is not qualified, can not meet the needs of making ventilation duct.

④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。

④ Measures: before using the ventilation pipe processing equipment to make the ventilation pipe, it is necessary to check the material factory certificate, material quality certificate and appearance thickness to ensure that the material is available.

2、山东通风管道翘角及弯头角度不准

2. The warping angle and elbow angle of Shandong ventilation pipeline are not accurate

①表现：矩形通风管道两相对平面、两端面不平行；折角不平直；对角线不相等；咬口不严。

① Performance: Rectangular Ventilation Duct two relative planes, two end faces are not parallel; inflection angle is not straight; diagonal is not equal; bite is not tight.

②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。

② Influence: it will cause uneven stress of ventilation pipe connection, uneven and straight ventilation pipe after installation, loose flange gasket, system air leakage, resulting in air conditioning load loss and shortening service life.

③原因：板下料放样不准确；通风管道两两平行，相对面的板料长度和宽度不相等。

③ Reasons: the layout of plate blanking is not accurate; the ventilation pipes are parallel, and the length and width of the opposite plate are not equal.

④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。

④ Measures: during blanking, the sheet metal should be strictly angled, and the length, width and inspection diagonal of each sheet should be controlled within the allowable range; after blanking, the two sheets opposite to the ventilation duct should be overlapped to check the dimensional accuracy.

山东通风管道加工的小编的介绍不知道大家有没有了解到呀？根据小编说的几点通风管道加工中出现的一些质量问题，大家在选购通风设备的时候一定要在这几个方面留心一下，避免购买到存在质量问题的产品，影响后期的使用效果。

Shandong ventilation pipe processing of small series of introduction do not know you have to understand it? According to some quality problems in the process of ventilation pipe processing, we must pay attention to these aspects when purchasing ventilation equipment, so as to avoid purchasing products with quality problems and affecting the later use effect.
