The normal operation of the duct production line is inseparable from the normal operation of the machine. Therefore, in order to ensure the normal operation of the machine and daily production of the air pipe does not appear stops caused by faults, it is necessary to carry out maintenance of the
duct production line.
1. The material requirements of the flexible pipe of the air duct cleaning system are relatively high, which requires it to have the characteristics of dustproof, good tightness and the smooth inner wall. The connection between it and the duct equipment is relatively precise, and the appearance requirements of the tuyere are also relatively strict, which require it should be qualified, the border and blade should be smooth and smooth.
2. When making the air valve, there should be a mark for opening and closing. The fitting of multi-blade valve blades should be the same, and the wheelbase deviation should be within 1mm. For the flexible pipe, its tightness should be appropriate, the length should be within the scope of construction specifications, and meet the design requirements. Cracking and distortion are not allowed.
3. For the production requirements of the hood, the specific performance is to maintain the balance of the complete shape with the size deviation within 2mm per meter. Rotational parts of fire damper need strong anticorrosive property so that it can close exactly.
