Dust explosion has always been one of the disastrous accidents that are difficult to prevent and control in the industrial production field. It seriously threatens the safety of industrial production, exposing the problems and severe situations in the field of safe production, and also exposing the awareness of relevant practitioners in accident prevention. And led wall light manufacturer suggested that you may be lack of knowledge.
Metal processing plants, coal storage sheds, flour processing plants, starch processing plants, milk powder processing plants, feed processing plants, paper mills, furniture plants, cotton processing plants, plastic plants, dye plants, chemical plants, etc. are all high incidence of dust explosions. field. The installation of high-quality explosion-proof lights can effectively avoid dust explosions and play an extremely important role in ensuring personal safety and improving environmental quality.
Explosion-proof grade is an important indicator used to measure the explosion-proof performance of lamps. The application places of explosion-proof lamps with different explosion-proof grades are also different. The precautions for purchasing explosion-proof lighting are as follows:
1. Only explosion-proof lamps with explosion-proof qualification certificates can be used in dangerous places where flammable gas and dust exist. Explosion-proof lamps can prevent arcs, sparks and high temperatures that may be generated inside the lamp from igniting flammable gases and dust in the surrounding environment. To achieve the purpose of explosion-proof.
2 The selected lamps must be certified by the national authority for explosion-proof, produced in full accordance with national explosion-proof standards, have excellent explosion-proof and anti-static capabilities, and can work safely in various flammable, explosive and strong corrosive gas places.
3. The explosion-proof lamp should adopt a constant current output drive circuit, which has short-circuit and open-circuit protection functions to ensure that the output light effect does not change with voltage fluctuations. The light source adopts imported high-power single LED, with low energy consumption and high luminous efficiency. The service life of the light source can be as long as 50,000 hours, which fully realizes the purpose of long-term maintenance-free, energy saving and environmental protection. The electrical box adopts a suspended design to effectively prevent heat conduction, greatly reducing the temperature rise of the LED driving power supply, and extending the service life of the driving power supply.
4. In order to meet the requirements of the light distribution design of the explosion-proof lamp, the lamps need a unified dimming configuration to achieve the best light output, so as to be suitable for the lighting requirements of various flood lighting places. The shell of the explosion-proof lamp series is made of high-purity aluminum die-casting, and the surface is electrostatically sprayed at high temperature. It has excellent anti-corrosion performance. Each joint surface is sealed accordingly to ensure good waterproof, dust-proof, anti-corrosion and explosion-proof performance.
5. In order to meet the installation needs of different places, explosion-proof lights should be equipped with high-strength brackets, which can be installed in various positions such as walls, steel frames, guardrails, and equipment planes.
