Automatic Self-Cleaned Suction Filter
Automatic pressure filters
Automatic pressure strainers
1 Working principle
Automatic self-cleaning suction filter consists of the primary filter strainer/screen, water inlet, suction nozzels, suck scanner, pressure gage switch, fine filter screen, sewage valve, solenoid switch, eletric motor. Scanner is spirally driven by the motor in the filter.
Dirty water enters the water inlet, where it enters the center of the fine filtration strainer/screen, the water then passes through the fine filtrationtrainer/ screen from the inside out and exits the outlet.
The unwated solid accumulates on the inner surface of the fine screen/net, creating a pressure differential, Once the pressure drop reaches a preset level, a rinse cycle is activated by the control system by opening the rinse valve to an atmospheric drain.
As a result, pressure drop in the motor chamber and the dirt collector assembly, the pressure drop creat a backfush stream, whick suchs the dirt off screen/net, similar to a vacuum cleaner. The backwash water is carried through the collector and ejected out of the holes in the motor.
The water being ejected out of the motor cause th collector to rotate, similar to sprinker, in addition, the pressure drop in the motor chamber, cause the collector assembly to move axially. This combination of movement ensure that the entire screen is cleaned each cycle.

3. PLC control system and its characteristics
The PLC controller is the electrical control core of automatic self-cleaning filter. with all kinds of protection, alarm function. with a wide range of control, time control, pressure control, its filtration degree is quite high. The use of high-speed CPU chip, a variety of parameters can be set off memories of its own internal watchdog circuit, SMD components using advanced technology, liquid crystal display simple and clear operation.
