What is the purpose of the explosion-proof LED light flame arrester?
Explosion-proof LED lights should be checked from the nameplate and product manual before the equipment: explosion-proof type, group; protection level of the shell; equipment mode and fastener requirements for equipment, etc. The equipment of explosion-proof lamps should be fixed reliably, the fastening bolts should not be replaced arbitrarily, and the spring washers should be completely. The sealing ring for dustproof and waterproof should be placed as it is. At the cable entry, the cable and the sealing gasket should be closely matched, and the section of the cable should be round. The remaining wire inlets must be blocked according to the explosion-proof type, and the compression nut must be tightened to seal the wire inlets.
Lamps with different light sources are suitable for different places. For example, ceiling lamps using ordinary incandescent bulbs and fluorescent lamps are mainly used for lighting in places with a floor height of about 4 meters such as homes, classrooms, and office buildings; gases with larger power and light source volume Discharge lamps are mainly used for lighting in stadiums, hypermarkets and factories with a floor height of 4 to 9 meters. In order to obtain sufficient height for the work surface and at the same time save electricity, fluorescent ceiling lamps are usually used for home store office lighting.
The principle and method of explosion-proof lighting is to try to eliminate the three conditions that constitute incineration and blasting.
(1) Control combustibles and avoid combustible gas, vapor and combustible dust and air to form explosive mixture. principle, eliminate or control one or more of the three conditions that constitute the incineration, so that the incineration is stopped. (2) Eliminate the ignition source. (3) Barrier air storage and airtight production.
2. What are the safety fire protection equipment?
Protective safety equipment, signal safety equipment, secure safety equipment, interlocking safety equipment.
3. What is the purpose of the fire gate?
The flame arrester is set up to prevent the flame from extending along the ventilation duct or production duct. Under normal circumstances, it is in the open state under the control of the fusible metal element. Once the temperature rises, after the fusible metal fuses, it will be affected by the weight of the gate itself.
The gas discharge lamp is used as the light source, which has high luminous efficiency and long life, and the average life can be as high as 10,000 hours; the power factor is greater than 0.9, the luminous efficiency is high, and the light transmittance is good.
