1. Less pressure loss, less backwashing: filtration pressure loss:
≤0.05MPa, backwashing displacement ≤0.5% filtered water
2. High degree of automation: The self-cleaning filter should be
backwashed by its own water pressure and filtered water to
automatically discharge the dirt, and it is still in the normal
water supply filtration state during the backwashing process.
3. Various control methods: cleaning control mode: differential
pressure control, timing automatic control and manual control. The
control system not only sets differential pressure cleaning, but
also has timing cleaning function (adjustable flushing interval)
and continuous cleaning function, control system. It can meet
long-term continuous work, and can automatically clean the filter
and clean it thoroughly.
4. Simple control operation: With differential pressure/manual/time
control function, the backwash pressure difference, backwash cycle
and backwash time can be set separately on the controller.
5. easy to install, by accounting for a small area
The water flows through the coarse screen and the fine screen, 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.
