1. Check the main fitting dimensions of the parts and components before assembling the cabinet so as to avoid any flaws.
2, explosion-proof box in the process of assembling the box does not allow the parts to scratch, touch, scratch the explosion-proof surface to ensure the smoothness of the surface.
3, explosion-proof box in the assembly of body screws and nuts fastening, it is strictly prohibited against or use inappropriate screwdriver and wrench.
4, explosion-proof box in the assembly of electrical components before the box according to the requirements of pressure test, pressurization 1MP, maintain 10-12S. It should ensure no obvious deformation of the box and no leakage.
5, explosion-proof box in the assembly of the electrical parts of the box to pay attention to the installation position is correct, install a solid, ensure the stability of the box.
6. The explosion-proof box is marked with a marking machine in the assembly box, and the line number is clear and complete. Wiring attention to the color of the wire sequence and wire diameter to avoid confusion, and can not remember.
7, after the installation of electrical equipment according to electrical design requirements for debugging.
8. After the commissioning, tighten the wiring harness, install the slot cover, and pay attention to the connection of the grounding cable. The grounding wire can be wound with Φ20-30 round bars for 6-8 turns to reduce the movement damage.
9, before fastening the lid, apply a layer of 0,1-0,3mm3# calcium grease on the explosion-proof surface of the box evenly. This is anti-corrosion and waterproof.
10. When tightening the lid, use 18N and M tightening torques to tighten the screws across, symmetrically, gradually, and evenly.
Explosion-proof junction box is a special equipment used in all kinds of high-risk places. Compared with civilian junction box, it is a junction box with explosion-proof function through various explosion-proof transformations. The use of aluminum alloy die-casting or stainless steel welding, explosion-proof junction box according to the classification are: According to the functional material form is divided into: Intrinsically safe explosion-proof junction box, aluminum alloy explosion-proof junction box, stainless steel explosion-proof junction box, steel explosion-proof junction box; The use of structure is divided into: wall-mounted explosion-proof junction box and vertical explosion-proof junction box.
