How To Find The Stroke Setting
NOTE: Read
this procedure, then study the example be
-
fore
determining the stroke setting.
1.
Set
the adjuster to 480 on the indicator (12).
Operate
the pump to measure the Maximum Full Stroke
Output
of the displacement pump,
measure the out
-
put
in
ounces.
2.
Multiply
the
Maximum Full Stroke Output
by 0.375
(37
1/2% – a constant number) which gives the
Mini-
mum Output Possible.
3.
The
Output Range
is all of the numbers between the
Minimum
Output Possible and
Maximum Full Stroke
Output.
4.
Determine
the
Lowest Number
in the Output
Range
which
can be evenly
divided into the Container Size,
and
then divide that number into the total ounces of
the container to get the
Ounces Per Cycle.
5.
Subtract the Minimum Output Possible from the
needed Ounces Per Cycle to determine the Vari-
able
Number
.
6.
Subtract the Minimum Output Possible from the
Maximum Full Stroke Output to determine the
Output
Range Number
.
7.
Divide the Variable Number by the Output Range
Number
to determine the
Percent of Range.
8.
Multiply the Percent of Range by 4.83 (a constant
number)
to determine the
T
rial Setting.
EXAMPLE:
1. In this example, the Maximum Full Stroke Output
is
8 oz. The Container Size is 20 oz.
2. 0.375
(37 1/2% – Constant Number)
x 8
(Maximum Full Stroke Output)
= 3
(Minimum Output Possible)
3. 3 oz. to 8 oz.
is the Output Range
4. 20
(Container Size)
4
(Lowest number in Output Range
which divides evenly into
Container Size)
= 5
(Ounces Per Cycle)
5. 5
(Ounces Per Cycle)
– 3
(Minimum Output Possible)
= 2 (V
ariable Number)
6. 8
(Maximum Full Stroke Output)
– 3
(Minimum Output Possible)
= 5
(Output Range Number –
not
related
to ounces per cycle)
7. 2 (Variable Number)
5
(Output Range Number)
= .40
(or 40% of the Range)
8. 4.83
(Constant Number)
x 40
(Percent of Range)
= 193
(YOUR TRIAL SETTING)
NOTE: Remember, the pump exhausts twice each
cycle,
so
in this case, set the counter to 8 (2 x 4)
rather than 4 which is the lowest number in the
output range which divides evenly into the con-
tainer
size.
