In the production process of the air duct, various types of
air duct machine must be used, which is also determined according to the type of air duct to be produced. Whether these air duct processing equipment can efficiently produce high quality air ducts Do a good job of equipment inspection in advance.
1. Ensure that the joints of the equipment components are tightly sealed without leakage; the inner surface of the air duct of the cleaning system must be smooth and smooth; it is forbidden to have transverse joints and reinforcements inside the tubes or to reinforce them with convex ribs.
2, the wind pipe bite joints should be tight, uniform width, no holes, half bite and burst and other defects. Straight pipe longitudinal staggered staggered; wind pipe straight angle, uniform arc, both ends of the plane parallel non-warping angle, the surface roughness of not more than 10mm; wind pipe and flange connected firmly, flanging flat, the width should be greater than 6mm.
3. The distance between the hole flange bolts and rivets should not exceed 150mm. There is no screw hole in the weld and the screw holes are interchangeable; there are no obvious traces, cavities and other defects on the surface of stainless steel plate and aluminum plate air duct. There is no damage to the surface of the steel plate duct.
Whether the structure of air duct machine is in good condition and whether the function is complete is an important factor affecting the forming of the air duct. Therefore, debugging should be done before production to ensure the smooth progress of the processing process.
