When choosing explosion-proof lamps, many customers don’t know what they need. Some don’t even know how many watts or where they are used, which makes it difficult for us to quote customers because of the choice of explosion-proof lamps. , Installation, use and maintenance are all indispensable links to ensure the long-term safety, reliability and high efficiency of explosion-proof lamps, and must be given full attention. Here I briefly introduce the points that need to be paid attention to.

One. Explosion-proof lights use mobile phones //./

. Selection personnel must understand the basic working principle of explosion-proof lamps and be familiar with explosion-proof signs.

. According to the level of explosive hazardous areas, accurately select the explosion-proof category, type, level and temperature group of the lamp.

. Understand the use of environmental conditions and work requirements, and reasonably choose explosion-proof lamps with various functions. For example, the enclosure protection level of explosion-proof lamps used outdoors should be at least IP. In places where colors are required to be distinguished, explosion-proof lamps such as high-pressure mercury lamps and high-pressure sodium lamps cannot be used because these two light sources have poor color rendering.

. Read the product manual in detail, understand the product's performance, precautions and product limitations, and understand the content of all product marks. If there is an 'x' symbol after the explosion-proof certificate number, it means that the lamp has a specific applicable place. You should consult the product instruction manual and nameplate to clarify the applicable place requirements.

Two. Explosion-proof lamp installation

. The installer must be professionally trained.

. Read the product manual carefully, and clarify the meaning of all the logos of the product.

. Strictly install explosion-proof lamps and lanterns according to the requirements specified in the product manual. For example, some lights have a designated installation location, which must be strictly followed by the installer. Some lamps have temperature signs at the cable entrance, and the installer must use high temperature resistant cables and wires.

Three. Use of explosion-proof lights

. The user should understand the performance of the explosion-proof lamps, and if there is any abnormality, they should cut off the power and report for repair. Non-full-time maintenance personnel are not allowed to perform repairs without authorization.

. The users of portable explosion-proof lamps and lanterns should read the instructions in detail, clarify the place of use and product performance, and use the lamps in strict accordance with the usage requirements. The battery should be replaced or charged in time when it is used up, and the battery should be taken out if it is not used for a long time to avoid corrosion of the lamp. It is strictly forbidden to open the lamp and replace the battery or light source in explosive dangerous places.

Explosion-proof lamps should be maintained regularly and repaired in time during use.

. Maintenance personnel need to undergo on-the-job training to understand the performance of the lamps and clarify the requirements for use. Maintenance personnel must have professional knowledge and be familiar with the structure of lighting products.

. Regularly eliminate dust and dirt on the shell of explosion-proof lamps and improve the light efficiency and heat dissipation performance of the lamps. The cleaning method can be sprayed with water (above the shade of the sign on the lamp) or wiped with a damp cloth according to the protective ability of the lamp housing. When cleaning with water spray, the power supply should be cut off, and it is strictly forbidden to wipe the plastic shell (transparent part) of the lamp with a dry cloth to prevent static electricity.

. Check the plastic shell (transparent part) of the lamp for serious discoloration. If the discoloration is serious, it indicates that the plastic has aged. Check whether the transparent parts have been impacted by foreign objects, whether the protective net is loose, desoldering, corrosion, etc. If so, stop using it and repair and replace it in time.

. If the light source is damaged, turn off the light in time and notify the replacement to avoid long-term abnormal state of electrical components such as the ballast due to the failure of the light source to start.

. If there is water in the lamp cavity of the lamp used in a humid environment, you should promptly replace the sealing parts to ensure the protective performance of the shell.

. When opening the lampshade, you should open the cover after disconnecting the power supply according to the requirements of the warning sign.

. After opening the cover, check whether the flameproof bonding surface is intact, whether the rubber seal is hard or sticky, whether the wire insulation layer is green and carbonized, whether the insulation and electrical components are deformed and scorched. If these problems are found, they should be repaired and replaced in time.

. The model, specification, size and performance of the light source, parts and electrical components after the repair and replacement shall be exactly the same as the light source, parts and electrical components before the repair and replacement.

. Before closing the cover, use a damp cloth (not too wet) to gently wipe the light return and transparent parts of the lamp to improve the light efficiency of the lamp. A thin layer of replacement type anti-rust oil should be applied to the flameproof joint surface. When closing the cover, pay attention to whether the sealing ring plays a sealing role in the original position.

. The sealed part of the lamp should not be disassembled and opened frequently.
