Shenhai Explosion-Proof
Definition:
Explosion-proof lights are designed for hazardous locations where combustible gases and dust are present. They prevent potential internal arcs, sparks, and high temperatures from igniting surrounding flammable gases and dust, thereby meeting explosion-proof requirements.
Principle:
The principle of flameproof type, according to the European standard EN13463-1:2002 “Non-electrical equipment for potentially explosive atmospheres – Part 1: Basic methods and requirements,” is a type of explosion-proof design that allows internal explosions while preventing the spread of flames. This is one of the most commonly used explosion-proof methods. Due to the metal material generally used in the construction of these lights, they offer good heat dissipation, high shell strength, and durability, making them popular among users. Many components of increased safety explosion-proof lights, such as lamp holders and interlock switches, also adopt a flameproof structure. Electrical equipment with a flameproof enclosure is known as flameproof electrical equipment. If an explosive gas mixture enters the flameproof enclosure and ignites, the flameproof enclosure can withstand the explosion pressure of the internal explosive gas mixture and prevent the explosion from spreading to the explosive mixture around the enclosure.
This is based on the principle of gap explosion-proofing, where the metallic gap prevents the spread of explosion flames and cools the temperature of the explosion products, extinguishing the flames and suppressing the expansion of the explosion. This design principle is widely used in various industrial sites that produce combustible materials, such as approximately two-thirds of coal mines and over 80% of chemical industry production workshops where explosive materials are present. The extensive use of electrical instruments, sparks from friction, mechanical wear, static electricity, and high temperatures are unavoidable, especially when instruments and electrical systems malfunction. With oxygen omnipresent in the air, many industrial sites meet the conditions for an explosion. When the concentration of explosive substances mixes with oxygen within the explosive limit, an explosion can occur if there is a source of ignition. Therefore, adopting explosion-proof measures is crucial.
With the strict enforcement of safety regulations by the government, I believe that doing business ethically and not compromising the safety of clients or their enterprises for short-term gains is vital. If someone is purchasing explosion-proof lights, it signifies the presence of hazards in their facilities and their trust in you as a supplier. I urge all suppliers to read this article and understand the importance of not risking the trust of users for immediate profits. The popularity of our LED explosion-proof lights among users is not due to low prices but because of their effective performance and stable quality.
