BYD Company Limited
BYD Company Limited was founded in 1995 and was listed on the Hong Kong Main Board on July 31, 2002. The company is headquartered in Shenzhen, Guangdong, China, and is a high-tech private enterprise with three major industrial sectors: IT, automotive, and new energy. The automotive rain shower line device uses a rainwater recovery system for the first time, significantly reducing and saving a large amount of water waste. It employs the Fumide Environmental SCF-N self-cleaning filter to effectively filter the water used for washing vehicles, which then enters a clean water pool for reuse. The self-cleaning filter removes particulate matter from the water, and the filtered water basically does not cause clogging of the spray nozzles in the sprinkler system, greatly reducing system failures and labor costs. The number of installations at BYD's electric bus factories is increasing daily, with one SCF-N80-1.0 installed at the Qingdao BYD automobile factory, one SCF-N60-1.0 at the Hangzhou BYD automobile factory, and installations pending at BYD in Changsha, Dongfeng Motor, and BYD in Shenzhen.
Dirty water enters from the filter inlet, first passing through the coarse filter screen to remove larger particles, then reaching the fine filter screen. During filtration, the fine filter screen gradually accumulates dirt and impurities from the water, forming a filter impurity layer. Because the impurity layer accumulates on the inside of the fine filter screen, a pressure difference forms on the inside and outside of the fine filter screen. When the pressure difference of the self-cleaning filter reaches the preset value, a switch signal is sent to the control box PLC system to start a cleaning cycle. Cleaning process: The cleaning mechanism of the fully automatic negative pressure suction filter is a stainless steel spiral up-and-down moving suction scanner. It is hollow in structure, with several suction nozzles vertically distributed at certain distances along its axis. The inside of the suction scanner communicates with the 3” drain valve. When the drain valve opens, the pressure difference between the internal water pressure of the filter and the external atmospheric pressure generates strong suction at each suction nozzle. At each suction nozzle, water flows rapidly from outside to inside in reverse, washing impurities attached to the inner wall of the filter screen into the suction nozzle, through the hollow shaft of the suction scanner, then discharged through the drain valve, completing the cleaning process which takes about 30-60 seconds. At this time, the pressure difference returns to normal, the cleaning process ends, and filtration resumes. During cleaning, the system continues to flow.
