It refers to a lamp used in places where flammable gas and dust exist, and can prevent arcs, sparks and high temperature that may be generated inside the lamp from igniting flammable gas and dust in the surrounding environment, and then reach the explosion-proof requirements. There are mainly explosion-proof explosion-proof lamps, mobile explosion-proof lamps and so on. Explosion-proof platform lights are suitable for lighting in flammable and explosive places such as petrochemical equipment, gas stations, and transfer stations.
Explosion-proof lamps and lamp shades should be able to automatically cut off the power before they are opened. However, because the interlocking equipment is complicated and difficult to complete, most lamps and lanterns only have warning signs with the words "No electrified opening" on the outer casing. And because the surface temperature of the bulb is still very high after the power is turned off, if the lampshade is opened immediately, there is a danger of gas mixture. Therefore, incandescent lamps, high-pressure sodium lamps and other light sources with high surface temperature of the bulbs and lamps that can quickly open the cover should pay attention to this. .
The explosion-proof joint surface of the explosion-proof lamp should be properly maintained and not damaged; other paints are not allowed; there should be no rust layer on the explosion-proof surface. If there is slight rust, there should be no pockmark after cleaning. The sealing ring used for dustproof and waterproof must be kept intact, which is very important for the increased safety lamps. If the sealing ring is severely damaged, replace it with a sealing ring of the same specification and material, and replace the entire lamp if necessary. When overhauling, pay attention to whether the lampshade is in good condition. If there is a break, replace it immediately.
