One of the most important explosion-proof principles of LED explosion-proof lighting fixtures is to limit the temperature of the surface of the enclosure that contacts the explosive gas, explosive dust, the surface of components or electronic components, and to limit the temperature of the electrical contact surface below its minimum ignition temperature or ignition temperature. . LED explosion-proof lights for outdoor use require a waterproof drive. Led explosion-proof lights used at gas stations need shockproof!
Installation and maintenance:
Explosion-proof lamps must be checked from the nameplate and the product specification before installation: explosion-proof type, type, grade, group; degree of protection of the enclosure; installation method and fastener requirements for installation. The installation of explosion-proof lights must be securely secured, the fastening bolts must not be replaced, and the spring washers should be complete. The dust-proof and waterproof seals should be placed as they are. When the cable enters the line, the cable and the sealing gasket should be closely matched. The section of the cable should be round, and the surface of the jacket should not have defects such as asperities. Excess inlets shall be sealed in an explosion-proof type, coated with 201-replacement rust preventive oil, and tighten the compression nut to seal the inlet. Led Explosion-Proof Lights Where there is a strong shock, use a fall prevention ring to prevent the lamp from falling off.
Precautions:
1. Regularly eliminate dust and dirt on the explosion-proof lamp housing to improve the light efficiency and heat dissipation performance of the lamp. The cleaning method can be based on the protection capability of the lamp housing, using water spray (over the shade on the lamp) or using a damp cloth. When cleaning with water spray, the power should be cut off. Never use a dry cloth to scrub the plastic housing (transparent part) of the lamp to prevent static electricity.
2. Check whether the transparent parts have been affected by foreign material, whether the protection network has loosened, stripped, and corroded. If so, use should be stopped and repaired and replaced in time.
3. The light source should be turned off in a timely manner to notify the light to be replaced, so as to avoid the ballast and other electrical components being in an abnormal state for a long period of time because the light source cannot be started.
4. If the accumulated water in the cavity of the lamp used in the humid environment should be cleared in time, replace the sealing parts to ensure the protective performance of the enclosure.
5. When you open the lamp cover, you should press the warning board to open the cover after turning off the power.
6. After opening the cover, check whether the flameproof joint surface is intact, whether the rubber seal is hardened or becomes sticky, whether the wire insulation layer is green and carbonized, and whether the insulation and electrical components are deformed and burned. If these problems are found, they should be promptly repaired and replaced.
7. Before applying the cover, apply a damp cloth (not excessively wet) to light the light and transparent parts of the light fixture to improve the light efficiency of the light fixture. A layer of 204-1 displacement rust preventive oil should be applied thinly on the flameproof joint surface. When the lid is closed, attention should be paid to whether the sealing ring plays a sealing role in the original position.
8. The sealed part of the lamp should not be frequently disassembled and opened. Patent zone road sealing technology; more in line with national explosion-proof new technology.
