专注通风管道加工·排烟罩

空气中的氧气也是维持人们生活的基本元素，因此应始终保持室内通风，以满足人们对氧气的需求。这也是通风管道加工对人们生活的影响，下面我们来看看济南通风管道加工可能会存在两个质量问题。

Oxygen in the air is also the basic element to maintain people's life, so indoor ventilation should always be maintained to meet people's demand for oxygen. This is also the impact of ventilation pipe processing on people's lives. Now let's take a look at two quality problems that may exist in ventilation pipe processing in Jinan.

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，有显着的压痕、裂纹、砂眼和锈蚀等情况;通风管道平面下沉，旁边面向外凸起，有显着的变形。

① Performance: the surface of the plate is uneven, the thickness is uneven, and there are significant indentation, cracks, sand holes and rust; The plane of the ventilation pipe sinks, and the side faces outward, with obvious deformation.

②影响：工作时通风管道漏风，空调负荷添加，同时风寿命和性能被影响。

② Impact: the air leakage of the ventilation duct during operation, the air conditioning load is added, and the air life and performance are affected.

③原因：资料不合格，不能满意制造通风管道的需求。

③ Cause: The data is unqualified, and the requirements for manufacturing ventilation ducts are not satisfied.

④办法：在使用通风管道加工设备制造通风管道前，要先查看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, the factory certificate, quality certificate and appearance thickness of the data shall be checked to ensure that the data are available.

2、通风管道翘角及弯头视点禁绝：

2. The warping angle of the ventilation pipe and the view point of the elbow are forbidden:

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: two opposite planes and two end faces of rectangular ventilation duct are not parallel; The corner is not straight; Diagonal lines are not equal; The bite is not tight.

②影响：会使通风管道连接受力不均匀，装置后的通风管道不平直，法兰盘垫片不严密，体系漏风，形成空调负荷损失，并且缩短使用寿命。

② Effect: It will cause uneven stress on the connection of ventilation pipes, uneven ventilation pipes behind the device, untight flange gaskets, air leakage of the system, resulting in air conditioning load loss and shortened service life.

③原因：板下料放样禁绝确;通风管道两两平行，相对面的板料长度和宽度不相等。

③ Cause: The blanking and setting out of plates are strictly prohibited; The two sides of the ventilation pipe are parallel, and the length and width of the sheet on the opposite side are not equal.

④办法：打开下料时，应对板料严格角方，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，应将通风管道相对面的两片板料重合查验尺寸准确性。

④ Method: When the blanking is opened, the angle of the sheet shall be strictly controlled, and the length, width and diagonal of each sheet shall be checked to 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.
