Explosion-proof lamp precautions

The explosion-proof lamp and lamp cover should be able to cut off the power automatically before opening. However, because the interlocking device is complicated and difficult to implement, most of the lamps only have a warning sign on the outer casing that is clearly prohibited from being powered on. Because the surface temperature is still high after the lamp is powered off, if the lamp cover is turned on immediately, there is still the danger of igniting the explosive gas mixture (mainly the explosion-proof structure), so the incandescent lamp, the high-pressure mercury lamp, the high-pressure sodium lamp, the light source with high surface temperature of the bulb. Pay attention to this when you can quickly open the cover.

When replacing the bulb (tube), the explosion-proof joint surface of the explosion-proof lamp should be properly protected and must not be damaged; the cleaned explosion-proof surface should be coated with phosphate paste or 204-1 anti-rust oil, and it is strictly forbidden to paint other paint; There shall be no rust layer on the surface. If there is slight rust, there shall be no numbness after cleaning. Sealing rings for dustproof and waterproof must be guaranteed to be in good condition, which is very important for increased safety lamps. If the seal is damaged seriously, replace it with a seal of the same specification and the same material and replace the entire lamp if necessary. Pay attention to the integrity of the lamp cover during maintenance, and replace it if it is broken.

It does not occupy the horizontal space indoors or outdoors and is particularly suitable for installation in locations with limited space, such as kitchens, bathrooms, narrow corridors, etc.
Advantages:
Good ventilation:Aluminum single hung windows can be opened to a large extent, so that indoor and outdoor air can circulate fully, effectively improving the indoor ventilation effect. In addition, some aluminum single hung windows can also realize multi-sash linkage to further increase the ventilation area.
Wide field of vision: Due to the particularity of its opening method, aluminum single hung windows will not be blocked by window frames like casement windows when opened, which can provide a wider field of vision and make the indoor space more transparent and bright.
High safety: When the window sash is closed, it fits tightly with the window frame, and with high-quality sealing strips, it can effectively prevent rain, dust, wind and sand from entering the room. At the same time, some aluminum single hung windows are also equipped with safety locks and other devices to enhance the anti-theft performance of the windows.
Easy to clean: The window sash can be tilted inward or outward, which is convenient for users to clean the inside and outside of the window, solving the problem of difficult cleaning of high-rise windows.
