通风管道生产中常见的2大问题

2 common problems in the production of ventilation ducts

通风管道具有使空气流通,降低有害气体浓度的作用,但是由于一些原因,可能导致加工出来的风管有问题。下面我们带大家详细了解一下通风管道生产中常见的2点问题以及解决方法。

Ventilation duct can make air flow and reduce the concentration of harmful gas, but for some reasons, it may lead to problems in the air duct. Now let's take a detailed look at 2 common problems in ventilation pipe production and their solutions.

一、风管翘角及弯头角度不准

1。 The angle of the wind pipe and the angle of the elbow is not allowed。

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。

Performance: Rectangular duct two opposite planes, two ends of the plane is not parallel; Angle is not straight; Diagonal is not equal; bite is not strict。

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。

Influence: It will make the connection of air duct uneven, the installation of air duct is not straight, flange gasket is not tight, the system air leakage, resulting in air conditioning load loss, and shorten the service life。

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。

The reason is that the blanking is not accurate, and the length and width of the 22 parallel pipes are not equal.

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。

Measures: When blanking is unfolded, the sheet should be strictly angled, and the length, width and diagonal of each sheet should be checked so that their deviation can be controlled within the allowable range.

二、加工材料未达标

Two, processing materials are not up to standard.

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。

Performance: The surface of the plate is not uniform, the thickness is not uniform, there are obvious indentation, cracks, trachoma, scarring and rust, etc。 Air duct plane subsidence, lateral protrusion, obvious deformation。

影响:运转时风管漏风,空调负荷增加,同时风寿命和性能被影响。

Impact: during operation, air leakage is increased, air conditioning load is increased, and wind life and performance are affected.

原因:材料不合格,不能满足制作风管的需求。

The reason is that the material is not qualified and can not meet the demand of making air duct.

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。

Measures: Before making air duct with air duct processing equipment, we should check the material certificate and material quality certificate as well as appearance thickness to ensure that the material is available.

可见,通风管道生产中经常会遇到加工材料不达标以及风管翘角及弯头角度不准的现象,因此我们想要生产出高质量的风管,就必须做好充足的事前和操作准备,今天讲的大家都记住了吗?希望能够给您带来帮助。

Visible, often encountered in the production of ventilation ducts processing materials do not meet the standards and duct angle and bend angle is not accurate, so we want to produce high-quality duct, we must do a good job in advance and operational preparation, today we all remember? I hope I can help you.
