Automatic Backwash Hydraulic Screen Filter / Before Precision
3:Automatic drain valve
4: Hydraulic piston
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.
