1、加工材料未达标
1. The processing materials have not reached the 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、结疤和锈蚀等情况;通风管道平面下沉,侧面向外凸起,有明显的变形。
(1) performance: uneven surface of the plate, uneven thickness, obvious indentation, cracks, sand, scars, and rust, etc. the ventilation pipe surface subsidence, the side protruding, and 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: when running, the ventilation duct leaks, the air conditioning load increases, and the wind 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) reasons: the material is not qualified and can not meet the demand for ventilation ducts.
(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 ventilating pipe processing equipment to make the ventilation pipe, we must first check the material factory certificate and material quality certificate and the appearance thickness, so as to ensure that the material is available.

2、通风管道翘角及弯头角度不准
2. The angle of the warping of the ventilation pipe and the angle of the elbow are not allowed
(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(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(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。
(1) performance: the rectangular ventilation pipe two is not parallel to the plane and the two ends; the angle is not equal and straight; the diagonal line is not equal; the bite mouth is not strict (2): the ventilation pipe connection is not uniform, the ventilation pipe after installation is not flat, the flange gasket is not tight, the system leakage wind is caused, and the air conditioning load loss is caused, and shortens Lifetime (3) Reasons: inaccurate laying out of the plate; two parallel ventilation ducts, opposite to the length and width of the plate is 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: when the blanking is unfolded, the plate material should be strictly corner square, the length, width and diagonal line of each sheet material should be checked to make their deviations within the allowable range. After the blanking, the size of the two sheet materials in the ventilation pipe should be rejoined to check the accuracy of the size.
