How to choose the right explosion-proof lights according to different environments?

Explosion-proof lamps and lanterns selection, installation, use and maintenance are to protect the long-term safety of explosion-proof lamps and lanterns, reliable, efficient work indispensable link, must be given full attention. Many customers in the selection of explosion-proof lamps, are not clear what they need to be explosion-proof lamps, some do not even know how many watts, used in what places do not know, the following will explain how to choose the right explosion-proof lamps according to different environments?

First, explosion-proof lamp selection

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

1.2 According to the level of explosive hazardous places, accurately select the explosion-proof category, type, level and temperature group of lamps and lanterns.

1.3 Understand the use of environmental conditions and working requirements, a reasonable choice of explosion-proof lamps and lanterns with a variety of functions. For example: outdoor use of explosion-proof lamps and lanterns shell protection level of at least IP65 or more. In the requirements of the place to identify the color, you can not choose poor color rendering lamps and lanterns, according to the actual needs of the lamps and lanterns corresponding to the display value.

1.4 Read the product instructions in detail, to understand the use of the product performance, precautions and product limitations, to understand the content of all the signs of the product. Such as explosion-proof certificate number after the “X” symbol, indicating that the light has a specific place of application, you should consult the product instructions and nameplates, clear place of application requirements.

 Second, explosion-proof lamp installation

2.1 Installers must be professionally trained.

2.2 Read the instruction manual of the product in detail, and make clear the meaning of the content of all signs of the product.

2.3 Install explosion-proof lamps and lanterns accurately and strictly according to the requirements specified in the product instruction manual. For example, some lamps have a specified installation location, the installer must strictly comply with. Some lamps and lanterns in the cable lead to the population of the temperature mark, the installer must choose high-temperature cables, wires.

Three, explosion-proof lamp use

3.1 Users should understand the performance of explosion-proof lamps and lanterns, found that there are abnormal phenomena should be disconnected to repair, not full-time maintenance personnel are not allowed to carry out maintenance without authorization.

3.2 Portable explosion-proof lamps and lanterns users should read the instruction manual in detail, clear use of places and product performance, and use the lamps and lanterns in strict accordance with the requirements of use. Batteries should be replaced or charged in a timely manner, long-term non-use should be removed from the battery to avoid corrosion of the lamp. It is strictly prohibited to open the lamps and lanterns in explosive hazardous places, replace the battery or light source.

Fourth, explosion-proof lamp maintenance

Explosion-proof lamps and lanterns should be regularly maintained and repaired in a timely manner in the course of use.

4.1 Maintenance and repair personnel need to be trained by the post, to understand the use of lamps and lanterns performance, clear use of the requirements. Maintenance personnel must have professional knowledge, familiar with the product structure of the lamps and lanterns.

4.2 Regular elimination of explosion-proof lamps and lanterns shell on the accumulation of dust and dirt, to improve the luminous efficiency of the lamps and lanterns and heat dissipation performance. Cleaning can be based on the shell of the lamps and lanterns protective capacity, using water spray (lamps and lanterns on the sign IP65 or more) or wipe with a wet cloth. Spray cleaning, should cut off the power supply, is strictly prohibited with a dry cloth to scrub the lamps and lanterns plastic shell (transparent parts), to prevent the generation of static electricity.

4.3 Check the lamps and lanterns plastic shell (transparent parts) there is no serious discoloration, such as serious discoloration, indicating that the plastic has been aging. Check whether the transparent parts have been impacted by traces of foreign objects, the protection of the network has no loosening, de-welding, corrosion and so on. If so, should stop using, timely maintenance and replacement.

4.4 Damage to the light source should be turned off in time to notify the replacement, so as to avoid the ballast and other electrical components in a long-term abnormal state due to the light source can not be started.

4.5 Lamps used in humid environments such as water in the lamp cavity should be removed in a timely manner, replace the sealing components to ensure that the shell protection performance.

4.6 When opening the lampshade, the cover should be opened after disconnecting the power supply according to the warning sign.

4.7 After opening the cover, it should be checked whether the explosion-proof bonding surface is intact, whether the rubber seals become hard or sticky, whether the wire insulation layer is green and carbonized, and whether there are deformation and scorch marks on the insulating parts and electrical components. If these problems are found, they should be repaired and replaced in time.

4.8 The models, specifications, dimensions and performance of light sources, parts and electrical components after repair and replacement should be identical to those before repair and replacement.

4.9 Before closing the cover, a wet cloth (not excessively wet) should be used to lightly wipe the lamps and lanterns back to the light and transparent parts, in order to improve the luminous efficiency of the lamps and lanterns. In the explosion-proof combination surface should be thinly coated with a layer of 204-1 replacement rust prevention oil, close the cover should pay attention to whether the sealing ring in the original position to play a sealing effect.

4.10 Sealed parts of the luminaire should not be frequently dismantled and opened.
