Automatic back wash filter housing
working principle:
FQ automatic back wash filter housing, The filtered liquid flow
in the housing, filtered by the filter screens, the
impurities are trapped inside the filter screens.
when the impurities become more and more, and the pressure
difference between the contaminat side and clean side will be
increase. When the pressure difference reaches the set value, the
differential pressure gauge will signal, and the filter system
will start to back wash the filter screens, and then the clean
liquid flow out from the housing, the impurities will be
discharged by the drain valve.
Automatic back wash filter housing
working process:
1) The gear motor drive the intermediate shaft and the washing
arm do rotation together.the positioning switch control the The
rotation angle, and let the point is meet with the cleaned filter
screens.
2) Opening the drain valve, and there will be pressure difference between the drain outlet and clean side(outside the filter screens).
3) Because of the pressure difference, the liquid in the clean side will flow to the filter screens inside from the outside of the filter screens, and then the filter system will start to back wash the filter screens, and the impurities will be washed down and discharged from the drain valve.
4)The time of back washing can set by yourself, when the time is up to the setting value, the drain valve will be closed, and back washing process of this group of filter screens is over, and then the next back washing process of other groups of filter screens will be start.
5)When all the filter screens are cleaned, the Zero switch will
control the washing arm to original position, and the filter
system will stop back washing and continue thefiltration
process.
Because the back washing process is proceed one group by one
group, so the filter system will keep the filtration working all
the time.
The back washing process
setting:
* Setting the pressure difference: There is a differential pressure gauge in the filter system, you can set the valve by yourself.
* Setting the time: There is a Time setting device in the filter
system, you can set the start time of back washing and the time
of duration.
If you set the pressure difference and also the time, the setting
pressure difference will have priority.
* Manual operation: when you are debuging and maintaining the
filter system, you can press the "TEST" , and start the
back washing process.
