Operation
5.3
Differential pressure control
Mode of operation:
The impurities filtered off and caught on the
filter cloth cause an increased differential
pressure between the inlet and the outlet
of the filter at an adequate flow rate. The
differential pressure switch registers the
differential pressure prevailing on the filter. If
the differential pressure reaches the set
value, the backwashing procedure will be
automatically initiated.
The differential pressure switch is directly
flanged to the filter via intermediate flange.
Setting the differential pressure:
The selector shaft of the differential pres-
sure switch is set at the adjusting screw. The
value can be adjusted with a screwdriver
between 0.06 and 0.6 bar, see scale.
If the value is set too high, dirt may accumu-
late with low flow rate. During times of higher
water removal the differential pressure will
increase to an extent that damages at the
screen may occur.
