Flow rate adjustment
A flow rate can be adjusted by adjusting a stroke rate and stroke length.
The stroke rate is indicated in %. 100% stroke rate means the maximum flow rate.
Stroke rate adjustment is a main way to adjust a flow rate.
Stroke length is the moving distance of the plunger.
A flow rate per shot can be controlled by changing stroke length. The widest
moving distance is defined as 100% stroke length.
First adjust a flow rate by stroke rate adjustment. Use stroke length adjustment
for the range where stroke rate adjustment can not reach.
Determine a suitable stroke rate and a stroke length, taking account of operat-
ing conditions and liquid characteristics.
The following procedure is recommended.
Change a stroke rate with stroke length 100% to adjust a flow rate.
See "Stroke rate adjustment" on page 42 and "Stroke length adjust-
ment" on page 44 for detail.
Measure a flow rate.
If a flow rate is lower than a specified level, increase a stroke rate
and measure the flow again.
Change a stroke length for fine adjustment.
Measure the flow again to see the specified level is obtained.
