Structural principle of the Automatic self-cleaning filters
Automatic self-cleaning filters from the shell, multiple filters,
backwash mechanism, electrical control boxes, gear, electric valves and
differential pressure controller and other components. Diaphragm within the
shell of its cavity is divided into upper and lower chamber, the chamber is
equipped with multiple filter core, so make full use of the filtering space,
significantly reduce the size of the filter, backwash is installed under the
cavity sucker .
The cloud liquid through the entrance into the IVC
filter, but also by the partition hole into the filter cavity, is larger than
the filter cartridge slot of the impurities are retained, the net fluid through
the gap to reach the cavity, and finally sent from the exit. Automatic
self-cleaning filter cartridges use high-strength Johnson wedge filter, through
the pressure control, timing control of self-cleaning filter. When the filter
impurities accumulate in the filter pressure drop caused by increased surface
to the desired value, or timer to preset time, the electrical control box
signals, driving anti-rinse body. When the filter backwash suction Handicap and
imports are on, the drain valve open, then the system pressure relief drainage,
suction and filter inside the emergence of a relative pressure lower than the
pressure of negative pressure outside the filter area, forcing part of the net circulating
water flow from the filter cartridge outside of the inside wall on the
adsorption of impurities in the filter particles flowing into suction valve
within the discharge from the sewage. Johnson made a specially designed filter
net effect of internally generated spray, any impurities will be washed away
from the smooth inner wall. When the filter pressure drop will return to normal
or timer set time after the motor stops running, the electric discharge valve
closed. Throughout the process, materials continue to flow.

 The
filter Reducer with high-quality aluminum
alloy die casting shell structure, good
heat dissipation, noise, light weight, can
carry large power.
Seal
enhanced with standard PTFE double seal
structure, reliable sealing performance,
and long life and tight.
The
differential sampling part of the switch
with adjustable differential pressure controller,
differential, correct feedback signal;
The
filter using high-strength filters,
high precision seamless, effective filter
area, pressure drop, high efficiency backwash;
The
flower plate with 304 stainless steel
filter, and the interface work backwash
suction mirror treatment;
The
backwash suction cup structure and the use
of PTFE backwash suction from the whole
body, to ensure that sucker with a long-term
filter tube sheet seal enhanced backwash
effect;
The
electric control part of the filter using
PLC programmable controller, cleaning mode
with differential pressure control, timing
control and manual control in parallel mode,
cleaning procedures for using time positioning
mode, a small amount of anti-wash water,
wash thoroughly;
All
electrical control box with post bed outdoor
waterproof structure through the screen.
