Self-cleaning filter 
 Self-cleaning filters, automatic self-cleaning filter is Filter Equipment Co., Ltd. Beijing Lauren's main sewage produced filtration products, filtration equipment Co., Ltd. Beijing Lauren's self-cleaning filter is in the introduction, digestion and absorption of foreign filtration technology made on the basis of research and development. Self-cleaning filter biggest advantage is to be treated water through the inlet into the filter, water impurities will be attached to the body of the filter on the filter. When the impurities attached to a certain extent, making the filter pressure difference inside and outside the sides of the set value, starting automatic sewage, repeat operation, to filter results. 

 Self-cleaning filter scope of application: 
 Clean drinking water, sterile water for pharmaceutical, equipment, water, oil field water injection wells, industrial water, high temperature water, fruit juice beverage alcohol, fuel oil, acid and alkali corrosive fluids, paint, chemical solvent, slurry liquid, glue, ink, imaging with a liquid such as liquid lead and terminal filter media, non-standard can be customized, service in pure water, beverage alcohol manufacturers, oil solution treatment, filters manufacturing, medicine, electricity, electroplating, oil, chemicals , mining and other industries and business, home drinking water purification and filtration areas, the production of stainless steel and SAN material water purifier, water filter, cartridge filter housing, and water filter cartridge PP Melt Blown, Wound water filter, pore collapse membrane water filters and other products sold in all provinces and cities. 

 Self-cleaning filter Description: 
 A self-cleaning filter maximum working pressure: 2.5 Mpa 
 2. Minimum working pressure: 0.25MPa 
 3. Self-cleaning filter maximum working temperature: 90 ℃ 
 4. Maximum working pressure: 1.0MPa 
 5. Carbon steel shell, internal and external anti-corrosion surface spray 
 Composite stainless steel mesh skeleton 
 7. Filter optional stainless steel or other alloy materials 
 8. If the coarse dirt more, the optional auxiliary high-pressure backwash pump structure, self-cleaning coarse filter with anti-net-structure of the filter flushing 
 9. Self-cleaning filters and optional PLC control hydraulic controller 


 Self-cleaning filter structure and working principle: 
 1, Lauren unique self-cleaning filter filter housing overall shape, processing technology, to avoid welding steel filter housing caused by the leakage; high-strength ductile cast iron materials, excellent corrosion resistance, extending the life of the product; 
 2, Lauren's proprietary self-cleaning cartridge filter design and manufacturing technology, high-precision filter will never wear; 
 3, Lauren Self-cleaning filter and reliable intelligent control, filtering, cleaning, sewage automated operation, to achieve unattended and uninterrupted water supply; 
 4, Lauren Self-cleaning filter structure and function of a leading product design, compact structure, filtration area, high dirt holding capacity, pipeline pressure loss is small, low power consumption; 
 5, Lauren Self-cleaning filter design optimized control, anti-washing time is short, the sewage water consumption, saving water resources; 
 6, Lauren Self-cleaning filter product line covers the range of the flow and accuracy, a variety of structural forms, to adapt to the user complex working conditions; 
 7, the actual conditions of each parameter can be adjusted, simple, maintenance-free, long life 

 Self-cleaning filter device of the wedge-shaped core made of high strength filter, through the pressure control, timing control self-cleaning filter. When the filter surface impurities accumulate in the filter pressure drop caused by the increase to the set value, or the timer reaches the preset time, the electric control box signals, driving backwash body. When smoking Handicap and filter backwash being imported, the drain valve open, then the system pressure relief drainage, suction and the filter inside the emergence of a relative pressure lower than the pressure of negative pressure outside the filter area, forcing part of the net recycled water into the filter from the filter outside of the inside of the wall in the filter adsorption of impurities on the particles flowing into the Rang tray and discharged from the drain valve. Specially designed jet filter makes filter effect internally generated, any impurities will be washed away from the smooth inner wall. When the filter pressure drop back to normal or timer setting time has elapsed, the whole process, the materials continue to flow, backwash water consumption, to achieve a continuous, automated production. 

 Beijing Lauren filtration equipment Technology Co., Ltd. products are also suitable for cooling water circulation system, chilled water system, recycled water treatment system, air conditioning, heating and heating water circulation system, surface water filtration system, 
 Industrial circulating water system (mainly used in steel systems, chemical systems, etc.). Can also be used for wastewater treatment, tertiary treatment of sewage treatment plants, reducing the cost of fine filtration systems.
