Fasteners on the shell of explosion-proof explosion-proof distribution box

1. The fasteners should have sufficient mechanical strength, and when the shell explodes, it will not cause the bolts to break;
2. The fasteners should have anti-rust and anti-loosening measures to ensure the clearance of the plane flameproof joint surface;
3. When tightening with bolts, if the spring washer is used to prevent loosening, it is only necessary to flatten the spring washer, and it is not advisable to tighten it too tightly;
4. In order to avoid the shearing of the fastening bolts by external force, the dimensions of the joint of the cover and the shell must be consistent;
5. In order to fasten firmly, it is not allowed to use plastic or light alloy to make bolts and nuts, and it is not allowed to tap the screw holes directly on the plastic shell;
6. The depth of the impermeable screw holes should ensure that after the bolts and screw holes are fastened, there must be a thread allowance greater than 2 times the thickness of the anti-loose washers;
7. The thickness of the periphery and bottom of the impermeable screw hole shall not be less than one-third of the diameter of the bolt, but there shall be a margin of at least 3.0mm;
8. Process through holes or screw holes that must penetrate the shell in structure should be blocked by cylindrical or threaded flameproof structures, and the exposed ends must be permanently fixed.

Pergunta frequentemente feita

Explosion proof, according to the National Electrical Code, applies to an apparatus enclosed in a case that is capable of withstanding a gas or vapor explosion. It means that, should there be an explosion, it will be contained within an enclosure.

Intrinsically safe enclosures are designed to limit the current, voltage, power and temperature of the circuits. As such, there is insufficient power in an intrinsically safe enclosure that could cause a spark or an ignition in an explosive atmosphere.

There is no difference except term. Flameproof design is one of the explosion protection technique extensively used for light fittings, JBs, motors in hazardous areas.
