The street lamp consists of three parts: explosion-proof lamp, light pole and base. The base is equipped with a ballast for the junction box or street lamp. The lamp post is sprayed on the surface of galvanized steel pipe. It has good anti-corrosion ability. The base is made of cast iron. It is firm and stable. The lamp post and base can be specially made according to user requirements. 01, 02, 05, 06 can be customized according to user requirements. Fitted with a light umbrella. Meet the requirements of GB3836-2000 and IEC60079 standards.
1. According to the actual lighting needs of the work site, determine the installation position and mode of the lamp and ballast, and then prepare the corresponding length of the three-core cable according to the distance from the lamp to the ballast contact and the distance from the ballast to the 220V power contact. Line (a cable that can be used with the lamp for distances up to 2 meters).
2. When the distance from the lamp to the ballast contact exceeds 2 meters, the three-core cable must be replaced. Evenly use the Allen key to unscrew the six hexagon socket bolts of the lamp housing. After the lamp body is partially removed, remove the three-core cable that comes with the lamp, and then connect the prepared three-core cable according to the original wiring.
3. Use a socket wrench to unscrew the fastening bolts on the ballast cover, remove the cover, and introduce one end of the three-core cable of the luminaire into the ballast chamber through the introduction device of the ballast output port. The black wire (or blue wire) and the yellow-green wire are respectively connected to the terminal blocks 4, 5, and 6 of the ballast, and then the compression nut is tightened.
4. One end of the prepared three-core power cable is introduced into the ballast cavity through the introduction device of the ballast input port, and then the L line (hot line), N line (middle line), and ground line are respectively connected to the ballast. On the terminals of the 1, 2, and 3 positions, 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.
Water Treatment
The main objectives of water treatment are:
1. Removal of suspended solids: This is
usually done through processes like sedimentation and filtration to remove
particles, dirt, and other suspended matter from the water.
2. Disinfection: Water treatment also
involves disinfection to kill or inactivate harmful microorganisms such as
bacteria, viruses, and parasites. Common disinfection methods include
chlorination, ultraviolet (UV) radiation, and ozonation.
3. Removal of dissolved impurities: Many
water sources contain dissolved impurities like minerals, salts, and organic
compounds. These impurities can affect the taste, odor, and overall quality of
water. Processes like ion exchange, reverse osmosis, and activated carbon
filtration are used to remove these dissolved impurities.
4. pH adjustment: The pH level of water can
impact its corrosiveness and taste. Water treatment may involve adjusting the
pH level through the addition of chemicals to make it more suitable for its
intended use.
5. Removal of specific contaminants: Water
treatment can also target specific contaminants that may be present in the
water, such as heavy metals, pesticides, and industrial pollutants. Advanced
treatment technologies like adsorption, chemical precipitation, and membrane
filtration are used for this purpose.
Overall, water treatment plays a crucial
role in ensuring the safety and quality of water for drinking, industrial
processes, agriculture, and environmental protection. It helps to prevent
waterborne diseases, maintain public health, and conserve water resources.
