Product principle
The water flows through the screen and the particles are retained on the inside of the screen of the filter element. The filtered water then flows out through the outlet.
Self-cleaning mode can be started by pressing, timing or manual three ways, following the principle of pressure difference.
When the internal and external pressure difference reaches the set value, the self-cleaning mode starts.Drain pipe hydraulic valve open, sucking the scanner to produce negative pressure suction nozzle inside, absorbing impurities, at the same time sucking scanner in under hydraulic motor along the inside surface mesh do reciprocating screw, movement, no cleaning blind area, impurities by the discharge outlet.
The cleaning time of self-cleaning filter is set by the controller in advance, the drain valve is closed after cleaning, and little water loss in cleaning process.
