Explosion-proof lamp requirements for cast aluminum enclosures

Explosion-proof light is generally classified according to the selected light source, explosion-proof structure type, and usage mode. According to the light source classification, there are explosion-proof incandescent lamp, explosion-proof high-pressure mercury lamp, explosion-proof low-voltage fluorescent lamp, mixed light source lamp, etc.; according to the explosion-proof structure type, there are explosion-proof lamps, increased safety lamps, composite lamps, etc.; Explosion-proof lamps and portable explosion-proof lamps.

The main scope of explosion-proof tools is: petroleum refining and petrochemical industry, coal mines, oil fields, natural gas chemical industry, chemical fiber industry, paint industry, fertilizer industry, various pharmaceutical industries. Oil wheels and liquefied petroleum gas vehicles, warehouses of business products, electrolysis workshops, communications equipment assembly workshops, places where tools are not rusted, wear-resistant and magnetically resistant.

We know that the enclosure of the explosion-proof lamp is not cast from pure aluminum, but there are many different metal colors produced by different processing techniques.

Aluminium-copper alloy explosion-proof tools are made of precious rare metals for synthesis, smelting, and forging. Face hardness HRC25 ° above, tensile strength δb> 75-85kgf/mm, all other technical indicators have reached the advanced level of similar foreign products. The continuous use of gas ethylene (concentration: 7.8%) ensures safety, and impact (bump), friction, and drop hammer do not generate spark explosion.
