Operation principle：
During normal filtration, pending water enters water inlet manifold 9 through total water inlet 7, is divided into three tunnels and respectively enters the first mistake
Device 1, the second filter device 2, the 3rd filter device 3 are filtered, the first via is through the first inlet valve 1A from the water inlet of the first filter device 1
Mouth 1E is filtered into the first filter device 1, water outlet 1F and first outlet valve of the water after filtering through the first filter device
1B enters total outlet pipe 14；Second tunnel the second inlet valve 2A is filled from the water inlet 2E of the second filter device 2 into the second filtering
It puts 2 to be filtered, water outlet 2F and second outlet valve 2B of the water after filtering through the second filter device 2 enter total outlet pipe 14；
The 3rd inlet valve 3A of 3rd tunnel is filtered from water inlet 3E into the 3rd filter device 3, and the water after filtering is through the 3rd filtering
The water outlet 3F and the 3rd outlet valve 3B of device 3 enter total outlet pipe 14.Water after three tunnel filterings passes through after importing total outlet pipe 14
Total outlet valve 6 and by-passing valve 13 are flowed out from total water outlet 12, complete filtering process.
During backwash, system is equipped with manual recoil, time control automatic backflushing and pressure difference control three kinds of recoils of automatic backflushing
Mold cleaning formula, can be manually to the first filter device 1, the second filter device 2, the 3rd filter device 3 when in manual recoil pattern
In any one recoil, when in time control automatic backflushing, the time that system is set by switch board 5 carries out automatically
Recoil, when controlling automatic backflushing in pressure difference, system recoils automatically by the pressure difference that differential pressure controller 4 is set.System is set
