Explosion proof light is used in hazardous places where combustible gases and dust are present. It can prevent the electric arc, spark, and high temperature generated inside the lamp from igniting the combustible gas and dust in the surrounding environment, to meet the requirements of explosion-proof lamps and lanterns. What should it pay attention to in daily maintenance and repair?
Maintenance personnel should be trained to understand the use of lamps and lanterns performance, and clear use requirements. Maintenance personnel should have professional knowledge and be familiar with the product structure of lamps and lanterns.
Regular elimination of dust and dirt on the shell of explosion proof light to improve the light efficiency and heat dissipation performance. Cleaning methods can be based on the protection of the lamp shell, the use of water spray (lamp logo shade above), or wiping with a damp cloth. When water spray cleaning, should cut off the power supply, and strictly prohibit the use of dry cloth cleaning lamps and a plastic shell (transparent), to prevent the generation of static electricity.
Check the explosion proof light plastic case for any serious discoloration, if the discoloration is serious, it means the plastic has been aging. Check whether the transparent parts have been subjected to foreign body impact traces, whether the protective mesh loses, off-welding, corrosion, etc. . If so, it should be discontinued and replaced promptly.
Light source damage should be a timely switch off lights, and replacement notice, to avoid the ballast and other electrical components can not start because of the ballast's long-term abnormal state.
The wet environment used in the lamp cavity if there is water should be removed in time, replacement of sealing components to ensure the protective performance of the shell.
When opening the lamp shade of explosion proof light, open the cover after the power is off according to the requirements of the warning board.
Opening the lid should be checked after the explosion-proof interface is intact, whether the rubber seals become hard or sticky, whether the wire insulation is green and carbonization, insulation and electrical components whether there is a deformation and scorch mark. If these problems are found, they should be repaired and replaced promptly.
The type, specification, size, and performance of the light source, parts, and electrical components after repair and replacement shall be the same as that of the light source, parts, and electrical components before repair and replacement.
Before closing the application of wet cloth (not too wet) light block luminaires and transparency, to improve the luminaire's light efficiency. The flameproof joint surface should be coated with a thin layer of 204-1 displacement rust-proof oil, when closing the cover should pay attention to whether the sealing ring is in the original position to play a sealing role.
The sealed parts of the luminaire should not be removed and opened frequently.
The above are the precautions for maintenance and overhaul of explosion proof light. If you have any other questions about this, please feel free to contact us.
