What should I do if the spiral duct machine bites and deviates?
Apr 09, 2022
How does a spiral duct machine bite and how does it work? The diameter of the circular duct (excluding the spiral duct) is greater than or equal to, and the pipe part is greater than or the total surface area is greater than 4m2.
If the edge of the rectangular air duct is larger than the insulating air duct, the length of the pipe is larger than that of the pipeline, or the single-sided area of the low-pressure pipe is larger than 1.2m2, and the high-pressure pipe is larger than 1.0m2, and strengthening measures should be taken;
Enhancements to unconventional elliptical dumping should be made with reference to rectangular pipes.
The bolts, nuts, washers and rivets used in the spiral duct machine should match the characteristics of the pipe.
Reinforcement of non-metallic pipes, in addition to complying with the provisions stipulated in Article 1: 1 The diameter or side of hard polyethylene pipes is larger, and the joints of air ducts and flanges shall be strengthened. The board shall not be greater than; 2 The reinforcement of organic and inorganic FRP pipes shall be the same as the material or anti-corrosion properties of the material of the object, as well as the whole of the pipe.
The production of rectangular pipe bends should generally be in inner and outer arc bends with a radius of curvature to the flat side. When used in other forms of bending, where the flat is larger than the flat, elbow fluid pieces must be provided.
The air duct of the purification air conditioning system should also meet the following requirements:
1. When the length of the rectangular pipe is less than or equal to, the bottom plate should not have a splicing seam; when it is greater than, there should be a horizontal splicing seam;
Auxiliary equipment of spiral duct machine
Since the spiral duct machine can only produce straight pipes, it developed a slender machine. Among them, the double-bend machine is operated by two separate work stations at the same time, which can achieve a high degree of production, flexibility: one is a crimping station, and the other is a work station for occlusion. Therefore, the machine can be used freely and the conversion does not take time. Both jobs work at the same time. Not only is the product pretty, but the bite is sturdy, sturdy, and lightweight!
