Explosion-proof explosion-proof boxes are used in places where there are dangerous gases and vapors for explosion. They are important measures to ensure safe production, prevent explosions and fires, and are different from general electrical products. The manufacturing process of the explosion-proof explosion-proof distribution box enclosure is quite important. If something goes wrong, it may not be a small problem. You know, as a product that guarantees security, problems are not minor problems. Therefore, if you need to buy explosion-proof distribution box friends, we must choose a strong manufacturer, so as to ensure the quality of the product in the largest case. So what are the specific precautions?
Explosion-proof explosion-proof distribution box shell manufacturing process precautions
1. All the explosion-proof distribution boxes are completed and the electrostatic spraying is performed on the inner and outer surfaces of the box. Sprayed with anticorrosive weatherproof paint, color is camel 09.
2. All explosion-proof distribution box enclosures for welding must be double-sided welding, and welding defects such as sand blasting must not be applied. Welds must be flattened after welding.
3. When there is a place where the box needs to be welded, it must be carefully and carefully welded, gradually adopting fixed equipment, annealing after welding, reducing deformation, and maintaining the integrity and appearance of the explosion-proof distribution box.
4, explosion-proof distribution box box screw holes and cover with, do not mix.
5, explosion-proof distribution box shell must be able to withstand the impact of 7J energy without damage
6, in the explosion-proof distribution box has not injection shape, his box tolerance should meet the requirements of GB/T1804-2000-M, not too much too much.
7. If there is a box that needs finishing, the explosion-proof surface of the processed part must not be rusted or impaired in performance, life, or appearance.
8, explosion-proof explosion-proof distribution box before spraying rust, the first use of organic solvents, lye, emulsifiers, steam, etc. to remove the surface of steel parts of grease, dirt, and then spray.
