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.
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. Processing materials not up to standard
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 Impact: during operation, the air duct leaks, the air conditioning load increases, and the air life and
performance are affected.
performance are affected.
③ Cause: the material is not qualified, can not meet the needs of making ventilation duct.
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. The warping angle and elbow angle of Shandong ventilation pipeline are not accurate
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 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 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 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.
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.
