Injection pumps delivery balancing<br />

In case the balancing error read on the test pieces is greater than 2<br />

cm³/min, then injection pumps deliveries should be adjusted.<br />

Plate 4 and rod 3 are blocked by screws 1 and 2. Loosen them.<br />

Move plate 4 rightwards with respect to rod 3 if you want to<br />

increase delivery.<br />

If moved leftwards delivery decreases. Make very small movements<br />

with the plate.<br />

Tighten screws 1 and 2 at a torque of 1,1 Nm.<br />

Note: Each time a pump/injector is replaced it is necessary to<br />

balance the deliveries.<br />
