Explosion-proof principle of explosion-proof lighting

Explosion-proof lighting is used in dangerous places where flammable gas and dust exist, and can prevent electric sparks that may be generated inside the lamp or high temperature during use to ignite the flammable gas and dust in the surrounding environment, so as to meet the requirements of explosion-proof. Different flammable gas mixture environments have different requirements for the explosion-proof grade of explosion-proof lighting and the explosion-proof form of the lamp. The function of explosion-proof lighting is simply to prevent explosions. Therefore, the use of explosion-proof lighting is very important for lighting in hazardous industries. So, what is the principle of explosion-proof and explosion-proof lighting? In order to achieve good explosion-proof and lighting effects, the shell of explosion-proof lighting is generally made of cast aluminum alloy, and the transparent parts are generally made of tempered glass. The surface of explosion-proof lighting is electrostatically sprayed with anti-corrosion materials. This still cannot achieve a good explosion-proof effect. Because the lamp may sometimes generate arcs and sparks inside the body during use, and the temperature of the lamp will rise, and it will easily cause an explosion when encountering flammable and explosive gases outside. Therefore, explosion-proof lighting must not only prevent its own temperature from being transmitted to the outside of the lamp housing, but also prevent accidents such as shocks and collisions during the use of the lamp. The flameproof explosion-proof lighting shell can withstand internal explosions without damage, and external collisions will not be damaged. And it can ensure that the flame gas inside reduces the energy when it propagates through the gap, and it is not enough to detonate the gas outside the shell. The above are the explosion-proof principles of explosion-proof lighting. As long as these principles can be adhered to, the explosion-proof lighting effect of explosion-proof lighting can be achieved. Therefore, the realization of a good explosion-proof effect of explosion-proof lighting is not only related to the production materials of explosion-proof lighting, but also inseparable from the principle of strict explosion-proof production. Users can also have some simple understanding of these contents before choosing to use explosion-proof lighting.
