With the rapid development of petroleum, chemical, mining and other industries, lighting lamps are more and more widely used in production, storage and rescue. How to prevent accidental explosion of lighting fixtures in explosive gas dangerous places has become a very important topic. As the lighting fixtures inevitably generate electric sparks or form hot surfaces when working, once they meet with the explosive gas mixture at the production or rescue site, they will lead to explosion accidents and directly endanger state property and citizens' lives. Therefore, as the most widely used lighting fixtures, the explosion-proof technology of LED explosion-proof lamps has attracted widespread attention and high attention.
The explosion-proof structure type of LED explosion-proof lamps shall be determined according to the regional grade and range of explosive gas environment. For example, explosion-proof lamps must be used in zone 1; Fixed lamps in zone 2 can be of explosion-proof and increased safety type, and mobile lamps must be of explosion-proof type. The grade or group of selected explosion-proof lamps shall not be lower than that of explosive mixture in explosive hazardous environment. At the same time, the impact of the environment on the explosion-proof lamp shall be considered, and the requirements of various environments such as ambient temperature, air humidity, corrosive or polluting substances shall be met. The protection grade and anti-corrosion grade of lamps shall be selected according to different environmental requirements. Especially when there is corrosive gas in explosive gas environment, it is very important to select lamps with corresponding anti-corrosion performance.
Before installation, the LED explosion-proof lamp shall be checked from the nameplate and the product manual, and the explosion-proof type, category, level and group shall be determined; Degree of protection of enclosure; Installation method and fastener requirements for installation. The explosion-proof lamp shall be installed firmly, the fastening bolts shall not be replaced arbitrarily, and the spring washers shall be complete. The sealing ring for dust prevention and waterproof shall be placed as it is during installation. At the cable inlet, the cable and the sealing gasket shall be closely matched. The cross-section of the cable shall be round, and the sheath surface shall be free of concave and convex defects. The excess inlet shall be blocked according to the explosion-proof type, coated with 201 replacement type rust preventive oil, and the compression nut shall be tightened to seal the inlet. In places with strong vibration, led explosion-proof lamps should use anti falling rings to prevent the lamps from falling off.
