通风管道是用于工业和民用建筑通风和空调项目的金属或非金属管道，它们是一种用于空气流通和降低有害气体浓度的市政基础设施，它主要由管道加工设备制成。但是，由于各种原因，可能导致加工出来的风管可能会出现问题。让我们一起来了解一下有哪些问题。
Ventilation ducts are metal or non-metallic ducts used in industrial and civil building ventilation and air conditioning projects. They are municipal infrastructure used for air circulation and reducing harmful gas concentrations, mainly made of pipeline processing equipment. However, due to various reasons, the processed air duct may encounter problems. Let's take a look at the issues together.
1、加工材料不符合标准
1. Processing materials do not meet standards
a、性能：木板表面不平整，厚度不均匀，有明显的压痕，裂纹，沙眼，疤痕和锈蚀，风管的平面下沉，侧面向外凸出，有明显的变形。
a. Performance: The surface of the wooden board is uneven, with uneven thickness, obvious indentation, cracks, sand holes, scars, and rust. The flat surface of the air duct sinks, and the side protrudes outward with obvious deformation.
b、影响：操作期间空气管道泄漏时，空调负荷会增加，同时会影响风的寿命和性能。
b. Impact: When the air duct leaks during operation, the air conditioning load will increase, and it will also affect the lifespan and performance of the air.
c、原因：材料不合格，不能满足制造风管的要求。
c. Reason: The material is not qualified and cannot meet the requirements for manufacturing air ducts.
d、措施：在使用管道加工设备制造管道之前，请检查材料工厂资格证书，材料质量证书和外观厚度，以确保可以使用这些材料。
d. Measure: Before using pipeline processing equipment to manufacture pipelines, please check the material factory qualification certificate, material quality certificate, and appearance thickness to ensure that these materials can be used.
2、风管翘角和弯头角度不准
2. Incorrect angle of air duct warping and bending
a、性能：矩形风管的两个相对平面，两端不平行，拐角不直，对角线不相等，咬口不严。
a. Performance: The two opposite planes of a rectangular air duct are not parallel at both ends, the corners are not straight, the diagonals are not equal, and the bite is not tight.
b、影响：将使风管的连接不均匀，安装后的风管不直，法兰垫片不紧，系统漏气，造成空调负荷损失，缩短使用寿命。
b. Impact: It will cause uneven connection of the air duct, uneven installation of the air duct, loose flange gasket, and system air leakage, resulting in air conditioning load loss and shortened service life.
c、原因：板下料放样泥杆 保定古筝 塑料增韧剂 拱形护坡模具 保定空调维修  托辊生产线不准确，管道彼此平行，并且相对板的长度和宽度不相等。
c. Reason: The layout of the board cutting is not accurate, the pipes are parallel to each other, and the length and width of the relative board are not equal.
d、措施：展开下料时，应严格限制纸张角度，并控制每张纸张的长度，宽度和检查对角线，以使其偏差在允许范围内，切纸后，应调节风量，将管道相对两侧的两张薄板重叠以检查尺寸准确度。
d. Measures: When unfolding the cutting process, the angle of the paper should be strictly limited, and the length, width, and diagonal of each paper should be controlled to ensure that the deviation is within the allowable range. After cutting the paper, the air volume should be adjusted, and the two thin sheets on opposite sides of the pipeline should be overlapped to check size accuracy.
