The dust explosion-proof infield is mainly an explosion-proof lamp used in a dust workshop. Can work safely in flammable and explosive places, for various indoor work sites, petrochemical installations, operations and offshore oil platforms, railways, iron and steel, fire protection, *, government departments need to use fixed lighting.
1. Explosion-proof function: It has passed the explosion-proof certification of the national authoritative organization and is produced in full compliance with the national explosion-proof standard. It can work safely and reliably in flammable and explosive dangerous places.
2. Energy-saving light effect: The use of high-intensity gas discharge as a light source, bright and soft, good color rendering, and an average service life of 10,000 hours or more.
3, professional design: excellent structural design and surface sealing treatment, durable, dust-proof and anti-corrosion.
4, installation methods: boom, ceiling and wall-mounted installation, the operation is simple and convenient.
Instructions
1, according to the actual lighting needs of the work site, determine the lamp and ballast installation location and method, and then press the lamp to the ballast contact point distance and ballast to the 220V power contact point to prepare the appropriate length of the three-core cable Line (a cable with a lamp is not more than 2 meters away).
2. When the distance from the lamp to the ballast contact exceeds 2 meters, the three-core cable needs to be replaced. That is, use an Allen wrench to unscrew the six hexagonal bolts of the lamp housing. After the lamp body is pulled out, remove the three-core cable that comes with the lamp, and then connect the prepared three-core cable according to the original connection.
3. Use a socket wrench to unscrew the fastening bolts on the ballast cover and remove the cover. Introduce one end of the three-core cable of the lamp into the ballast cavity through the introduction device of the output port of the ballast and put the red wire. The black line (or blue line) and the yellow-green line are respectively connected to terminals 4, 5, and 6 of the ballast, and then the compression nut is tightened.
4. Introduce one end of the prepared three-core power cable through the input device of the ballast input port and introduce it into the ballast cavity. Then, connect the L line (FireWire), N line (neutral line), and ground line to the ballast. On the terminals of terminals 1, 2, and 3, and tighten the compression nut.
5. Close the ballast cover and tighten the fastening bolts. Finally, connect the other end of the three-core cable to the 220V power supply according to the explosion-proof requirements.
6. When replacing the bulb, first cut off the power supply and check whether the hanging chain is hanging. Then use a hexagon socket wrench to open the six hexagon socket bolts on the lamp shell, carefully pull down the lamp body part to separate the lamp body from the lamp cap shell. Unscrew the old bulb and replace it with a new one.
Silicon carbide has the advantage of stable chemistry performance, high thermal conductivity, low coefficient of thermal expansion and good abrasive resistance. Silicon Carbide Abrasive Cloth usually used for grinding floor, stone, glass and metal.
Abrasive Cloth is the cloth with grinding compound. According to the different grinding compound, the abrasive cloth can divided into four kinds: Aluminum Oxide Abrasive Cloth, silicon carbide abrasive cloth, Zirconium Oxide Abrasive Cloth and Calcined Aluminum Oxide Abrasive Cloth and so on. According to the hardness, it also can be divided into flexible abrasive cloth,middle flexible abrasive cloth and hard abrasive cloth. Some of them can do waterproof or oil-proof. The shape of the abrasive cloth is roll, belt and sheet. The abrasive cloth is generally used for wood grinding and metal grinding. It can available in vary grits.
After 30 years` development, abrasive cloth grinding has become a complete and self-contained system of new processing technology. Because of its high processing efficiency, wide application range, strong adaptability, low cost, safe and convenient operation, it is well received by customers. In foreign countries, Abrasive Belt grinding technology has made great progress. It can be applianced for more and more processing object . It can process almost all engineering materials, from the general daily life appliance to application of large aerospace equipment.
