INSTRUMENTATION
PHYLOSOPHY:
This
system is suitable
to run either
manually or automatically.
Always the agitator
in the sump will
be running to
avoid the settlement
of solids and
uniform mixing.
Once the sump
is filled up
a pre determined
level by sensing
of this will
be done through
a level indicator
and then the
single will be
passed to the
pump to start
to pump the mixture
to the collection
tanks through
a buffer tank.
Similarly by
sensing the low
level through
the level indicator
the pump trip
off. Each sump
will provide
2 sets of level
sensing elements
to sense effectively.
Once the process
pump stops after
few seconds the
hot water pump
starts pumping
the hot water
for a specified
period for every
operation at
pressure of 5
kg/sq.cm to flush
out the delivery
line.

ADVANTAGES
OF REVISED SYSTEM
OVER THE EARLIER
ONE:
|
| |
- This
system
can
be
run
either
automatically
or
manually.
- As
there
are
no
other
valves
on
the
delivery
line,
expect
the
non
return
valve,there
will
not
be
any
problem
with
choking
/ clogging
- As there
are
no
pneumatic
/ electric
automatic
valves
this
system
is
a maintenance
free
system
- There
are
no
PLCs
in
the
system
the
cost
of
the
project
can
be
reduced
by
20%
of
the
last
offer
value.
- 100%
flushing
will
be
done
in
this
system
and
50%
more
water
supplying
- Minimum
and
maximum
percentage
of
solids
can
be
maintained
easily,
as
the
hot
water
quantity
is
fixed
which
we
know
also.
- With
the
addition
of
the
agitators
one
can
ensure
that
the
mixing
of
solids
and
liquid
will
be
uniform
by
which
we
can
reduce
the
choking
/ clogging
in
the
pump.
