FUNCTION
|
Our circulating
type control unit is an automatic system to check consistency,
liquid level and basic weight in one tank and it reacts rapidly
on the change of input consistency and circulates continuously
with new materials so there is no change on consistency and
liquid level. The consistency control ability is ±0.05%
( minor deflection may happens when there is a change on mixture
of material and freeness ) with remote weight control unit so
it is not necessary to go to distribution box or fan pump, which
is with digital type to control weight from operation panel.
|
|
|
To keep the consistency
at fixed level by abstracting the consistency of materials and
control the valve automatically on the corresponding difference
of consistency.
|
|
|
|
|
|
Firstly, it controls
the consistency as soon as possible to the indicated level by
mixture of the circulated new material and the balanced material
(approx.50%) after sending it to paper making machine through
the weight control valve.
|
|
|
To keep the constant
supply of quantity for materials by mixing the material and
dilution water in uniformity to control the weight and density.

EFFICIENCY OF CIRCULATING SYSTEM
|
.
It equalizes the density in vat and/or head box and
also makes the quantity of vertical and horizontal direction
in uniformity, and that the width of control is big due to automatic
control of small change of quantity. .
Improves productivity
by equalizing the lower limit. .
No trouble because it
shortens the time to stay as the inspector and valve to be installed
beside. .
Possible to eliminate the pipes of overflow on
the chest from vertical system. .
Can save the energy from
materials pump, and used machine chest can easily be eliminated.
.
Can save the time for substitution by confirming the modulation
effect as it controls nearby the vat and/or head box. .
Prevents lumping of additional materials so that expects improvement
of efficiency. .
The unit can control fastly and exactly
on the density, water level and quantity inside of the circulating
box (This is patented in Japan) .
This way of density control
system can control more exactly than 3 use of 3 units of old
times style density controller.
