4.- OPERATION
The electric motor (B) transmits its power by means of a reducer, made up of a
pinion (E) and a ring gear (F) solidary to an axis (I) and an eccentric (A) that
alternatively pushes and draws a shaft ( C) threaded to a piston ( D) .
As a spring is not necessary for the return of the piston ( POSITIVE RETURN) , the
motor transmits all its power both to the injection and to the suction, saving energy,
avoiding breackdowns, and ensuring a perfect and high precision dosing.
The micrometic regulator (G) increases or diminishes the stroke of the shaft and the
piston by means of a threaded pipe coupling (H) , modifying the injection flow. The
dosing flow is adjustable from a 0% to a 100%.
To regulate flow by means of an inverter is possible varying proportionally the
dosed flow by the frequency supplied by an electric motor. The dosing flow is
adjustable from, a 10% to a 100%.
INJECTION MODULES
In the same injector can be connected several injection modules to apportion different
products as long as they belong to the same serie:
MF1-MFD2 or MF2-MFD2 .
The maximum pressure of an MF dosing pump when combined with one or more
additional modules - MI or MID - can be limited. It will be the result of dividing 2.300
(for model MF1-MFD1 ) or 4.600 (for model MF2-MFD2 ) by the total sum of the flows
of the different installed modules, as long as this is not superior to the one specified
for each module. For this calculation we must use the flow of the diaphragm modules
multiplied by 2.
Example: Model MF2-300/3 + MI2-300 + MI2-200 + MID2-100.
Dosing pump of two injections per second, three-phase motor, with two additional modules
of 300l/h piston, one of 200l/h piston and one diaphragm module of 100l/h.
3 00 + 300 + 200 +2x100 = 1000
The maximum resulting pressure will be: 4.600/1000 = 4,6 bar
