What's the difference between the lamp tube and the ordinary lamp tube used for dust proof and explosion-proof lamps?
According to explosion-proof requirements design, OK
The appearance of the structure according to the safety regulations do. The lamp must be the same ~!
What are the differences between the lamp tubes of the dust proof and explosion-proof lamps and the ordinary lamps?The difference: explosion-proof lamp with a glass chimney and sealing ring, waterproof, dustproof, prevent flammable gas drilling on the explosion-proof electrical explosion-proof lamp, obvious certificate number, and the lamp shell cast with explosion-proof mark. Ordinary lamp can only be used in water, dust-free, flammable gas and other general places, simple structure.The explosion-proof lamp is used for dangerous places exist combustible gas and dust, to prevent the lamp may produce arc, spark ignition and high temperature surroundings of combustible gas and dust, so as to achieve the requirements of explosion-proof lamps. Also known as explosion-proof lamps, explosion-proof lighting. Different flammable gas mixture environment has different requirements for explosion proof grade and explosion proof form of explosion proof lamp. Refer specifically to GB3836, IEC60079.Scope of application1 suitable for explosive gas atmospheres zone 1 and zone 2 dangerous places; 2 for IIA, IIB, IIC explosive gas environment; 3 is suitable for combustible dust environment 20 zone, 21 zone and 22 zone 4; apply to the temperature required for T1 T6 environment.
