4.- OPERATION
The rotational motion of the motor is transmitted by the gear box that consists of
two major components, the pinion
(A)
and the ring gear
(B)
. The pinion and the
ring gear are linked to an axis with an eccentric bearing
(C)
that pushes the shaft
(D)
which is threaded to the diaphragm or the piston
(E).
The return movement is
made by the spring
(F)
.
While the pump is running the stroke length can be regulated by the flow regulator
knob
(G)
. It increase or reduce the discharge or suction’s strokes, either the piston
or the diaphragm, changing the injection flow. The dosing flow can be adjusted
between 0% and 100%.
The flow can be adjustable through an inverter, which will vary the engine speed of
the pump and will allow regulate the dosing flow between 10% and 100%.
