1. Uses and Working Conditions 1.1 Applications BYS-□×40 Explosion-proof corrosion-proof plastic fluorescent lamps According to GB3836.1-83 "General requirements for explosion-proof electrical equipment for explosive atmospheres", GB3836.2-83 "Explosion-proof electrical equipment for explosive atmospheres Explosion-proof electrical equipment "d"", GB3836.3-83 "explosion-proof electrical equipment for explosion-proof electrical equipment increased safety "e"" design and manufacture. The explosion-proof mark is ExedIICT4, which can be reliably used in lighting areas 1 and 2 in explosion hazardous locations with temperature groups T1-T4. The lamp housing is a plastic housing. The exposed metal mounting parts are stainless steel. The metal parts are plastic-coated and have good anti-corrosion performance. They are suitable for working lighting in corrosive gas environments.
2, the main parameters 2.1 model and meaning
2.2 rated working voltage: AC 220V, frequency 50Hz
2.3 Light source power: 20W, 40W single foot instant start fluorescent or 36W double foot fluorescent 2.4 protection class: IP55
2.5 The lamp can work normally in a temperature range of -20°C~+40°C. 2.6 Dimensions (mm) 20W:840×200×160,40W:1320×200×160
3, the main technical performance and structure BYS-□ × 40 explosion-proof anti-corrosion plastic fluorescent lamps, for increased safety-type electrical equipment, has a good protective performance, the components that may produce flowers to take special protective measures to improve the safety level.
3.1 The back cover material of the lamp is made of glass fiber reinforced plastic. The material of the transparent cover is polycarbonate. It has strong impact resistance, good anti-corrosion performance and light weight.
3.2 The plastic enclosure can withstand 28-day high temperature and day-night low temperature thermal aging test, without affecting the explosion-proof performance. The plastic housing is a fuel-resistant material that passes the 960°C hot wire test and is burned horizontally. The rear housing has antistatic properties.
3.3 The lamp is equipped with a power-off switch to ensure that it is in a de-energized state during installation and maintenance.
3.4 The light source uses a single-foot instant start fluorescent lamp, no starter, or two-foot Philips fluorescent lamp with electronic ballast.
3.5 Lamp maintenance and replacement light source is convenient. With a special key to operate the locking device, the transparent cover can be opened for operation.
4. Installation and maintenance 4.1 The installation form of the lamps and lanterns is: G1/2′′ pipe hanger, G3/4′′ pipe clamp type, ceiling type. Mounting dimensions shown.
4.2 The incoming cable is divided into cable wiring and steel pipe wiring. The cross-sectional area of ​​the cable is 1.5mm2 or 2.5mm2. The introduction of the cable when the cable is routed is sealed by rubber ring compression. When using a 1KV 3-core VV power cable lead-in line, concentric peelable holes can be used. When a plurality of wires are used to introduce the steel pipe wiring, a porous sealing ring is used, and the wires shall be respectively penetrated into the inner layers of the holes of the sealing ring for reaming. The porous sealing ring shall be used for the introduction of multiple wires in the steel pipe wiring. The wires shall be respectively penetrated into the holes of the sealing ring and be equipped with corresponding metal gaskets. When the lead wire is not led, the blind plug and gasket seal the plug. The factory lamps are installed by cable routing. G1/2′′ steel pipe wiring accessories are used as spare parts. The user needs G3/4′′ steel pipe wiring accessories to be specified when ordering.
4.3 Wiring: Both sides of the lamp can enter the line, but also one end of the line. Use a key to operate the locking device. Open the transparent cover and reflector, insert the wire into the wiring in the lamp, and then tighten the cover post. The wiring should be based on the “wiring diagram†within the fixture and the following wiring principles.
4.4 Lamp installation: Open the transparent cover, insert one end of the lamp into the lamp holder, pull the other lamp holder, and insert the other end of the lamp into the lamp holder.
4.5 Light source users bring their own. It is recommended to use a single-foot instant fluorescent lamp manufactured by Nanjing East China Electron Tube Factory, and a Philips Philips fluorescent lamp. The size of the lamp and lamp foot must meet the size requirements specified in IEC 81, 8310-1 and IEC 61, respectively.
4.6 In order to ensure the normal operation and safety of the lamps, users should pay attention:
4.6.1 Non-professionals are not allowed to turn on the light, and the key must be kept by professionals.
4.6.2 Do not remove the fastening parts.
4.6.3 When cleaning, use only a damp cloth to prevent static electricity, and avoid using chemical cleaners 4.6.4 Check that the lamp is in good condition.
4.6.5 install and replace the light source, do not damage the transparent cover and reflector.
4.7 Consumables Rubber cables and wire seals, the factory can mention the accessories, hardness of the seal ring is 45 ~ 50 degrees.
6. Ordering Information When ordering, the complete model, name, specifications and order quantity of the fluorescent lamp must be stated.

A highly
porous adsorbent material, produced by heating organic matter, such as coal,
wood and coconut shell, in the absence of air, which is then crushed into
granules. Activated carbon is positively charged and therefore able to remove
negative ions from the water such as chlorine and dissolved organic solutes by
absorption onto the activated carbon. The coconut shell carbon must be replaced
periodically as it may become saturated and unable to absorb.
One of the most
common applications for activated carbon is the reduction of the undesirable
tastes and odors present in many chlorinated water supplies. Activated carbon
has been successful for many years in the reduction of free chlorine from water
supplies. The end product is clean, fresh water with no objectionable taste or
odor characteristics.
