What are the requirements for the metal components of led устойчивост на експлозия light housings ?

The led explosion proof light housing kit product is a lighting equipment component designed for special environments. It has explosion proof function, can be used safely in flammable and explosive places, and provides stable lighting for the workplace.

Features of led explosion proof light housings kit products

The led explosion proof lamp housing kit products are made of high-strength materials, with excellent pressure and impact resistance. The surface of the shell is specially treated with good anticorrosion, dustproof and waterproof performance, which ensures that the lamps and lanterns can also work normally in harsh environments.

In addition, led explosion proof light shell kit products also have explosion proof function, its internal structure and circuit design are in line with the relevant explosion proof standards, to ensure the safe use in flammable and explosive places.

Application areas of led explosion proof light housings kit products

led explosion proof lamp shell kit products are widely used in petroleum, chemical, coal mine and other flammable and explosive places of lighting. In these areas, led explosion proof lamp housing kit products for the workplace to provide a stable, reliable lighting, to ensure production safety and smooth progress. In addition, led explosion proof lamp housing kit products are also suitable for tunnels, warehouses, docks and other places that require explosion proof lighting.

In the устойчивост на експлозия equipment certification process, why require manufacturers to provide the material report of the metal shell and metal parts of the shell?

Article 8 of GB/T 3836.1-2021 “Explosive Environment Part 1: General Requirements for Equipment” has detailed provisions for metal casing and metal parts of the casing. For different types of equipment, there are different material requirements.

Type II equipment is used in explosive atmospheres other than coal mine gas. When manufacturing shell materials for Class II equipment used in different equipment protection levels, for EPL Ga class, the total content (mass fraction) of aluminum, magnesium, titanium and zirconium shall not exceed 10%, of which magnesium, titanium and zirconium shall not exceed 7.5%; for EPL Gb class, the total content (mass fraction) of magnesium, titanium and zirconium shall not exceed 7.5%; for EPL Gc class, the total content (mass fraction) of magnesium, titanium and zirconium shall not exceed 7.5%; for EPL Gc class, the total content (mass fraction) of magnesium, titanium and zirconium shall not exceed 7.5%, except for the fans, fan shrouds and ventilation apertures baffle plates, which shall comply with the requirements of EPL Gb. EPL Gb requirements, there are no other requirements.

If the material composition limit of EPL Ga or Gb class equipment is exceeded, the equipment shall be marked with “x” in accordance with GB/T 3836.1-2021, paragraph 29.3e), and sufficient information shall be provided in the special conditions of use to ensure that the user can determine the suitability of the equipment for use under specific conditions such as preventing the risk of ignition caused by impact or friction.

Type III equipment is used in explosive dust environments other than coal mines. When manufacturing Class III equipment enclosure materials for use in different levels of equipment protection, the total magnesium, titanium, and zirconium content (mass fraction) should not exceed 7.5% for EPL Class Da and EPL Class Db, and for EPL Class Dc there are no requirements except that the fan, fan cowl, and vent baffle should comply with the requirements of EPL Db. Similarly, if the material composition limits for EPL Class Da or Db equipment are exceeded, the equipment shall be marked “x” as specified and information shall be provided in the special conditions of use.

When copper or copper alloys are used in acetylene-containing environments, the following requirements are to be met if the equipment enclosure and the enclosure of Ex components for external installation are made of copper or copper alloys: 1. coated with zinc, nickel, or other coatings; and 2. with a maximum copper content of the alloy not exceeding 65%. However, cable introduction devices, blocking fittings, threaded pipe fittings, and insulating sleeves as specified in Appendix a are not considered to be enclosure surfaces requiring coatings or copper content limits.

This is because in an acetylene environment, copper may form acetylides on the outer surface that can be ignited by friction or impact. These provisions are to ensure that the equipment used in explosive environments, its metal casing and enclosure metal parts can meet the safety requirements, reduce the risk of explosion, to protect the safety of personnel and equipment.

Amasly LED устойчивост на експлозия light introduction

Amasly explosion proof lamp shell is made of aluminum alloy die-casting molding, surface spraying pure epoxy resin powder, good corrosion resistance.

Light metal alloy materials that meet the standards are selected for melting, casting and other processes to prepare the shell and other components.

Mechanical processing of the shell, such as drilling, tapping, grinding, etc., the formation of explosion proof joint surface and thread. At the same time, surface treatment, such as spraying, galvanizing, etc., to improve the corrosion resistance and aesthetics of the shell.

The assembled lamps and lanterns are tested for explosion proof performance, including explosion proof test, explosion proof test, etc., to ensure that the lamps and lanterns meet the relevant standards and requirements, with specific reference to GB3836, IEC60079.

Amasly explosion proof lamp applications and advantages

Amasly LED explosion-proof lamps and lanterns are widely used in petroleum, petrochemical, chemical, pharmaceutical and other industries where flammable and explosive gases or dusts exist. Its advantages are mainly reflected in the following aspects:

1. high safety: through the explosion-proof design, to ensure that the lamps and lanterns in the internal explosion will not cause an external explosion, to protect the surrounding environment and personnel safety.

2. energy saving and environmental protection: LED light source has high luminous efficiency, low energy consumption and other advantages, compared with traditional light sources can significantly reduce energy consumption and carbon emissions.

3. Long service life: LED lamps and lanterns have a service life of 5 to 10 years, which greatly reduces the maintenance cost and replacement frequency of lamps and lanterns.

4. Good lighting effect: LED light source has good monochromaticity, narrow spectrum and other characteristics, can directly emit colored visible light, without filtering. At the same time, the lamps and lanterns distribution is unique, irradiation range content illumination uniformity, soft light without glare.

5. Strong adaptability: LED explosion-proof lamps and lanterns can be customized according to the needs of different industries to meet the lighting needs of different places.
