Talking about the Technical Advantages of LED Explosion-proof Lamps and Precautions for Installation and Maintenance
Carbon and its compounds A
wide variety of carbons can also be alloyed with iron, the most common
being carbon steel; graphite and clay can be used to make pencil cores
for writing and painting, and graphite can also be used as a lubricant
and pigment as a glass. Molding materials for
electrodes and electroplating, electroforming, electric motor brushes,
and neutron deceleration materials in nuclear reactors; coke can be used
in barbecue, drawing materials and ironmaking industries; gem-quality
diamonds can be used as jewelry, industrial Diamond is used for drilling, cutting and polishing, as well as tools for machining stones and metals. Carbon Products,Carbon Block,Metallurgical Coke,Graphite Electrode Ningxia Evergreen Trading Co., Ltd. , https://www.nxevergreen.com
Technical advantages:
As the LED is a solid-state cold light source, it has the advantages of high electro-optical conversion efficiency, small heat generation, low power consumption, operating voltage is safe and low voltage, long service life, etc. Therefore, high-power white LED is explosion-proof lamps, especially portable explosion-proof A very ideal light source for lamps.
LED explosion-proof light, patent area sealing technology; more in line with national explosion-proof new technology. The utility model relates to an electrical equipment used in a special industry, which mainly solves the lighting problem. The lamp housing includes a lamp shell, a lamp shade arranged at the front end of the lamp shell, a luminous body and a battery arranged inside the lamp shell, and a switch arranged on the surface of the lamp shell. :
The luminous body is a high-power LED module, and a wide voltage input driving circuit is arranged between the luminous body and the battery; the wide voltage input driving circuit includes a constant current chip, the constant current chip and the battery constitute a power module, and the LED module is connected to the constant On the current chip, the power module and the LED module are sealed together; ultrasonic welding is performed between the lamp housing and the lamp housing.
It uses the characteristics of low heat generation LED to achieve intrinsically safe explosion-proof, and the LED light source has a long life; the LED maintains a constant brightness at the end of full charge and discharge; a heat sink is arranged on the lamp housing to achieve effective heat dissipation of the LED module. It ensures the stability of use and is applicable to various industries such as coal mines, petroleum, railways, and flood prevention.
It is applicable to hazardous areas in Zone 1, Zone 2 and Class IIA, IIB, and IIC explosive gas atmospheres.
Installation and maintenance precautions
1. Regularly eliminate dust and dirt on the explosion-proof lamp housing to improve the light efficiency and heat dissipation performance of the lamp. The cleaning method can be based on the protection capability of the lamp housing, using water spray (over the shade on the lamp) or using a damp cloth. When cleaning with water spray, the power should be cut off. Never use a dry cloth to scrub the plastic housing (transparent parts) of the lamp to prevent static electricity.
2. Check whether the transparent parts have been affected by foreign material, whether the protection network has loosened, stripped, and corroded. If so, use should be stopped and repaired and replaced in time.
3. The light source should be turned off in a timely manner to notify the light to be replaced, so as to prevent the ballast and other electrical components from being in an abnormal state for a long time because the light source cannot be started.
4. If the accumulated water in the cavity of the lamp used in the humid environment should be cleared in time, replace the sealing parts to ensure the protective performance of the enclosure.
5. When you open the lamp cover, you should press the warning board to open the cover after turning off the power.
6. After opening the cover, check whether the flameproof joint surface is intact, whether the rubber seal is hardened or becomes sticky, whether the wire insulation layer is green and carbonized, and whether the insulation and electrical components are deformed and burned. If these problems are found, they should be promptly repaired and replaced.
7. Before applying the cover, apply a damp cloth (not excessively wet) to light the light and transparent parts of the light fixture to increase the efficacy of the light fixture. A layer of 204-1 displacement rust preventive oil should be applied thinly on the flameproof joint surface. When the lid is closed, attention should be paid to whether the sealing ring plays a sealing role in the original position.
8. The sealed part of the lamp should not be frequently disassembled and opened. Patent zone road sealing technology; more in line with national explosion-proof new technology.
