Explosion-proof floodlights are used in hazardous locations where flammable gases and dust are present. They can prevent arcs, sparks, and high temperatures inside the lamp from igniting flammable gases and dust in the surrounding environment, thereby reaching the explosion-proof requirements. Including explosion-proof searchlights, explosion-proof light, explosion-proof floodlights, explosion-proof lights and other explosion-proof lights. Different flammable gas mixture environments have different requirements for the explosion-proof grade and explosion-proof form of explosion-proof lamps.
Proof floodlight and floodlight distinction <br> <br> floodlight is a uniformly illuminated point light source in all directions, its irradiation range can be adjusted, the performance of a regular octahedron icons in the scene. Floodlights are the most widely used light source in renderings. Standard floodlights illuminate the entire scene.
Explosion-protected floodlights are hazardous locations for the presence of flammable gases and dust. They can prevent arcs, sparks, and high temperatures inside the lamp from igniting flammable gases and dust in the surrounding environment, thereby meeting explosion-proof requirements.
Use <br> <br> determine where and how the lamp according to the actual needs of the job site, then the electrical power contacts to prepare Φ8 ~ Φ14mm three-core cable in accordance with the corresponding length of the lamp.
Open the end cap of ballast, loosen the pressing nut of the ballast cable inlet, and lead the lamp cable and power cable through the compression nut to the internal terminal of the ballast, connect and fix, and tighten separately. Cables tighten nuts and tighten ballast end caps.
According to the determined installation location and method, the lamps and ballasts are installed, and the other end of the input cable of the ballast can be connected to the 220V power supply according to the requirements of explosion-proof.
Loosen the screws at the bottom of the lamp holder bracket, and adjust the lighting position by rotating 360° around the lamp holder; loosen the screws on both sides of the lamp holder, adjust the lighting angle of the lamp holder up and down according to the lighting requirements, and then tighten the screws.
When replacing the lamp, use a suitable screwdriver or other tool to insert the front cover into the holes on the two front side of the front cover, remove the bad lamp, and replace the new one.
Note 1, the lamp is installed in the equipped carton during transportation, and foam shock absorption is added.
2. When installing and maintaining the lamp, you must disconnect the power supply.
3, when used, the surface of the lamp has a certain temperature rise, which is a normal phenomenon; the temperature of the center of the transparent part is high and must not be touched.
4. When replacing the bulb, use the bulb of the same type and power; if you change the bulb type or power, replace the matching ballast accordingly.
A ballcock (also balltap or float valve) is a mechanism or machine for filling water tanks, such as those found in flush toilets, while avoiding overflow and (in the event of low water pressure) backflow. The modern ballcock was invented by José Antonio de Alzate y RamÃrez, a Mexican priest and scientist, who described the device in 1790 in the Gaceta de Literatura Méxicana.[1] It consists of a valve connected to a hollow sealed float by means of a lever, mounted near the top of the tank. The float is often ball-shaped, hence the name ballcock. The valve is connected to the incoming water supply, and is opened and closed by the lever which has the float mounted on the end. When the water level rises, the float rises with it; once it rises to a pre-set level, the mechanism forces the lever to close the valve and shut off the water flow. This is an example of negative feedback and of proportional control.
