Features self-cleaning filter 
 1, self-cleaning filter filter shells with original molding, 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, self-cleaning cartridge filter design and manufacture of proprietary technology, high-precision filter will never wear; 
 3, self-cleaning filter and reliable intelligent control, filtering, cleaning, sewage automated operation, to achieve unattended and uninterrupted water supply; 
 4, 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, self-cleaning filter design optimized control, anti-washing time is short, the sewage water consumption, saving water resources; 
 6, 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, self-cleaning filter parameters adjusted according to actual working conditions, easy operation, maintenance, long life. 


 Filter cleaning works: 

 1, filter backwash sewage cleaning time 
 Regular cleaning of sewage, you can set the time to 2-24 hours of action. When the timer time, open the drain valve electric actuators, filters for sewage 30-60 seconds, then turn valve actuator will rotate 90 ° to stop the cartridge-bit, change the water flow channels, an anti-flushing sewage 30-60 seconds . Steering valve reset and continue to discharge 3-5 seconds, then close the sewage outfall. 
 2, the pressure control of sewage 
 Pressure controller action value can be set to 0.03-0.07MPa, when the filter before and after the pressure reaches the set value pressure controller, pressure controller actions, filters, drain valve open end of 30-60 seconds, turn butterfly reset and continue to discharge 3-5 seconds, turn off the drain valve. 
 3, Manual Control 
 Through the control box on the button to clean up the direct control of the sewage. 


 Equipment Technology Co., Ltd. Beijing Lauren concerns self-cleaning filters and the difference between traditional filter 

 Automatic self-cleaning filter, compared with the conventional filtration equipment is a new type of filtration equipment. Automatic self-cleaning filter is a liquid under certain conditions the particles filter automatically remove the separation filter. Self-cleaning filter, compared with the conventional filter has the following characteristics: high degree of automation; pressure loss; do not have to manually remove residue. Most self-cleaning filters can be washed uninterrupted water supply. Automatic self-cleaning filters for industrial, agricultural, municipal, water desalination processes separation filter. 

 Self-cleaning filters and maintenance of knowledge 

 ◇ Automatic self-cleaning filters not long, the filter must be cleaned, remove the filter, wash, dry, kept sealed in plastic bags do not pollute, filters wipe store, not damaged. 

 ◇ Automatic self-cleaning cartridge filter for down the lotion to soak in the acid, the soaking time should not exceed 24 hours, usually in acid-base liquid temperature 25 ℃ -50 ℃. Recommended ratio of acid or alkaline water 10-20% of the time as well. High protein content of filtrate, the filter is best to use enzyme solution soaking, cleaning effect, updated re-use, must be cleaned and then steam sterilized. 

 ◇ Automatic self-cleaning filter element should be careful to take disinfection time and temperature of polypropylene at high temperature to 121 ℃ appropriate disinfection cabinet, steam sterilized under the 0.1MPa steam pressure to 130 ℃ / 20 minutes is appropriate, polysulfone and Teflon with steam sterilization, can reach 142 ℃, pressure of 0.2MPa, 30 minutes is appropriate, if the temperature is too high for too long, too much pressure can damage the filter.
