!
To ensure the good function of the
micropumps with thumb wheel,
the minimal flow rate has to be above 7
mm
3
/stroke.
!
If the carrier air pressure is to
high, there will be a problem with
the atomization. The lubricant particles
would be too fine and may keep sus-
pended in the air.
6.2.2 Bleeding the micropumps
• Set all the micropumps to their maximal
flow rate.
• Let the micropumps operate unit lubricant
is coming out from the nozzles.
!
In the case of a VE1B unit with
only 3 micropumps, the unused
outlet for air has to be closed. Therefore
turn the corresponding pressure regula-
tor fully to the right.
6.2.3 Neutralizing the micropump
delivery
A nozzle can be switched out at any time
without disturbing the good function of the
other nozzles fed by the VE1B unit.
Procedure
• Switch off the carrier air flow. Therefore
turn the air pressure regulator fully to the
right (air flow reduced to 0).
• Switch off the lubricant flow. Therefore
adjust the micropump flow rate to 0 (with
the ‘0’ metering ring, or turn the thumb
wheel fully to the left).
6.3 Micropump flow rate
adjustment
There are two different possibilities to adjust
the flow rate of the micropump. It can be ad-
justed by the use of a thumb wheel or me-
tering rings.
!
The VE1B unit has to be discon-
nected from power before any
adjustment.
!
Before adjusting the micropump
flow rate, the VE1B unit has to be
depressurized.
!
Table 3 on page 30 helps you for
an optimal adjustment of the mi-
cropump flow rate. It shows the flow rate
(mm
3
per minute) according to the me-
tered volume adjustment and the work-
ing frequency of the micropump.
