The explosion-proof light from China manufacturer, the lampshade should be able to automatically cut off the power before opening. However, because the interlocking device is complicated and not easy to implement, most lamps only have warning signs such as "Do not open with electricity" on the outer shell. And because the surface temperature of the bulb is still very high after the power is cut off, if you open the lampshade immediately, there is still the risk of igniting the explosive gas mixture (mainly referring to the explosion-proof structure), so incandescent lamps, high-pressure mercury lamps, high-pressure sodium lamps and other light sources with high surface temperature , And lamps that can quickly open the lid should pay attention to this point.

When replacing the bulb (tube), the explosion-proof light from China manufacturer's explosion-proof joint surface should be properly protected and must not be damaged; the cleaned explosion-proof surface should be coated with phosphating paste or 204-1 anti-rust oil, and brushing is strictly prohibited Other paints; there should be no rust layer on the explosion-proof surface, if there is a slight rust, there should be no pitting phenomenon after cleaning. The sealing ring used for dustproof and waterproof must be intact, which is very important for 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, and replace it immediately if it breaks.
The above is a brief introduction to the relevant knowledge of explosion-proof light from China manufacturer.
