The lamps can regularly eliminate the dust and dirt on the shell of explosion-proof lamps, keep the shell clean and clean, and can improve the light efficiency and heat dissipation performance of the lamps. The cleaning method can be based on the protection capacity of the lamp shell. If the protection level is IP65, 6 is the dustproof level, completely preventing dust from entering; 5 is the waterproof level, and there is no harm in washing with water. When cleaning with water jet, the power supply should be cut off, and it is strictly forbidden to use a dry cloth to clean the plastic shell (transparent) of the lamp to prevent static electricity.
Check whether the transparent parts have been impacted by foreign objects, and whether the protective net is loose, desoldered, corroded, etc. If so, stop using it and repair and replace it in time.
If there is accumulated water in the lamp cavity of lamps used in humid environments, it should be removed in time, and the sealing parts should be replaced to ensure the protective performance of the casing.
After opening the cover, check whether the flameproof joint surface is in good condition, whether the rubber seal is hardened or sticky, whether the wire insulation layer is green and carbonized, and whether the insulating parts and electrical components have deformation and scorch marks. If these problems are found, they should be repaired and replaced in time.
Before installing the LED explosion-proof lamp, check from the nameplate and product manual: explosion-proof type, category, level, group; protection level of the shell; installation method and fastener requirements for installation, etc. The installation of explosion-proof lamps should ensure that they are firmly fixed, the fastening bolts should not be arbitrarily replaced, and the spring washers should be complete.
The dustproof and waterproof sealing ring should be placed as it is when installed; at the cable entry, the cable and the sealing gasket should be closely matched, the cross section of the cable should be circular, and the surface of the sheath should not have defects such as unevenness. The excess wire inlet must be blocked according to the explosion-proof type, and the compression nut must be tightened to seal the wire inlet.
Check whether the transparent parts have been impacted by foreign objects, and whether the protective net is loose, desoldered, corroded, etc. If so, stop using it and repair and replace it in time.
