Automatic backwash filter works: being filtered liquid from the inlet into the filter, through the lower fixed plate into the filter, the filter outside of the liquid to flow from the inside and from the outflow of the filter cartridge outlet; backwash discharge of contaminants from outfall discharge. Backwash process: ◆ gear motor drive shaft via an intermediate wash arm rotates, the rotation angle of the wash arm by the photoelectric position switch control so as to clean the filter and being aligned; ◆ the drain valve open, so the filter is outside of the cleaning (clean side of ) and a pressure differential between the sewage; at a pressure difference, the cleaning liquid flow from the outer side of the inner flow of the filter to be cleaned, backwash contaminants accumulated in the inside of the filter is flushed, and is discharged through the outfall filter; ◆ Each filter backwash time has been set, when the set time reaches backwash, drain valve is closed, the end of the filter backwash process, geared motor driven again wash arm rotates to the next (group) filter backwash drain valve is turned on again, and so on for each filter backwash; ◆ After all filter cleaning, rinse arm under the control of the photoelectric switch back to the original position, a backwash end of the cycle; ◆ Because backwash is a (group) filter flushing process a (group) filter, so the backwash process, the filter can maintain the flow of the filtered state. Automatic Remote Control backwash filter system (Figure left): 1) with a color LCD that can display the inlet and outlet pressure and differential pressure curve and the work status of the device operation under various conditions; 2) automatically?? control backwash time, optimized debugger enables pressure set at the most reasonable value;? 3) infrared radio control high sensitivity, the rotation of the rotating arm increased by 6 times, thus reducing the time and anti-kickback red water consumption;? 4) industrial control computer system with a card, which enables remote observation and control;?? 5) standard industrial process control DCS interface with centralized control connection;? 6) USB interface can connect a keyboard, mouse? of the system parameters can be adjusted;? 7) provides overvoltage alarm systems, equipment failures and system fault diagnosis prompts. ? Backwash process set: ◆ pressure settings: Filter pressure regulator has a table for setting the filter pressure value; time setting: control box has a time setting device, according to user requirements Setting the time period filter backwash process; pressure setting and time setting is set to backwash process, two settings exist, and the pressure set priorities. ◆ Manual start: external pressure setting and time setting in addition to automatic backwash process. There are pressing the TEST button to manually start the backwash process, with automatic backwash time for debugging overhaul domestic water filters kqnglq.com applications, manufacturing process water supply, filtration ultrafiltration, reverse osmosis, softening pretreatment, ion exchange, oil injection water, cooling water, water reuse, groundwater, surface water turbidity purification, boiler return water, landscape water, municipal, green spray, agricultural irrigation, golf course water filtration.
