Filtration
Water enters the filter through
the "Inlet" (1) and passes through the coarse
screen (2) that functions as a "fist stop"
for rough particles. Water then reaches the fine screen (3),
which further purifies the flow by separating smaller particles
from the water. As more water flows through, impurities build
up on the fine screen. As impurities on the screen accumulate,
a pressure imbalance is built up between the internal screen
of the fine screen (3) and its external section.
Operation
Information for Model EC Self Cleaning Electric Screen Filter
The process is the same as the
above however there is no pre-filtration with a coarse screen
(2) as the filtration grade is 400 - 3000 microns.
Cleaning
Process
When the difference in pressure
reaches the preset value on the differential pressure indicator,
a series of events is triggered while water continues to flow
to the systems units. The controller transmits a signal for
a 10 second flushing cycle. The flushing valve (4)
opens, pressure is released from the hydraulic piston (5)
and water flows outside. Pressure in the hydraulic chamber
(6) and the dirt collector (7) is significantly
lowered resulting in a suction process via the suction nozzles
(8) to the dirt collector and from there to the hydraulic
chamber through the flushing valve (4) outside. The electric
motor (9) simultaneously rotates the dirt collector
(7) around its axis. The pressure is released from
the piston (5) and the high pressure inside the filter
causes linear movement of the dirt collector. The combination
of the linear movement and rotation efficiently cleans the
entire internal screen (3) surface.
At the end of
the 10 second cycle the flushing valve (4) closes and
the operation of the electric motor(9) is stopped.
The increased water pressure returns the hydraulic piston
(5) to its initial position. The filter is now ready
for the next cycle, with clean and filtered water flowing
through the "Outlet" (10).
The 10 second flushing cycle resumes operation whenever the
difference in pressure reaches the preset pressure value set
on the differential pressure indicator. If the pressure difference
remains unchanged after one cycle, another cycle will start
after a delay of 10 seconds.
