SQUARE DUCT MACHINE TESTING PROCESS

In the process of duct production, it is necessary to use various types of square duct machine, which is also decided by the type of duct to be produced. These square duct making machine can efficiently produce high-quality air duct, or to do a good job in advance equipment inspection.

1, To ensure that the joints of the equipment components should be closely leak-proof; cleaning the inner surface of the duct system must be smooth and flat, forbidden to have horizontal splicing and pipe reinforcement or the use of rib reinforcement method.

2, Duct bite should be close, uniform width, no holes, half bite mouth and crack and other defects. Longitudinal bite straight pipe staggered; duct angle flat, uniform arc, parallel to the ends of the plane without any curl, the surface roughness of not more than 10mm; duct and flange connection firm, flange formation, the width to be greater than 6mm.

3, The air duct flange bolts and rivets not more than 150mm spacing between the holes, the weld is not provided with screw holes, screw holes are interchangeable; stainless steel and aluminum duct surface is not obvious signs, pits and other defects, complex There is no damage to the surface of the steel duct.

Square duct machine structure is intact, the function is complete, etc., are important factors affecting duct forming. Therefore, it should be debugged before production to ensure the smooth progress of the processing.
