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
In the same injector can be connected several injection modules to apportion different
products as long as they are of the same serial number.
The maximum pressure of an
MF dosing pump when combined with one or more
additional modules can be limited. It will be the result of dividing K 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 in l/h - bar:
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.
300 + 300 + 200 + (2x100) = 1000 l/h
The maximum resulting pressure will be: 4.600/1000 = 4,6 bars
Example in GPH - PSI
Note: For 60Hz used the corresponding flow.
INJECTION MODULES
:
79 + 79 + 53 + (2x26) = 263 GPH
The maximum resulting pressure will be : 17.000 / 263 = 64,6 PSI
