N-2290 Series Electric Drive Dispenser
|
The
N-2290 Series dispensers are 2 Component, Positive
Displacement, Lance type Piston Metering units.
Powered by a large DC Servo Motor and Ball-Screw
Actuator, this series of dispensers are also
Constant Flow Rate types, due to the Closed
Loop Velocity Control of the Metering Unit.
Originally developed for dispensing precise
beads of structural adhesive in a manufacturing
process for Cruise Missiles, this series of
dispensers has also been used to precisely and
reliably fill cavities in Air Bag Crash Sensors.
PLC controlled and with an extensive Robot interface
that communicates important process information
and equipment status to a Supervisory controller,
this series of dispensers is especially suited
for precision work at high duty cycles.
The N-2290 Series dispensers can meter, mix
and dispense virtually any 2 part pump fed material,
from low viscosity pourable fluids, to viscous
pastes as high as 3 McP and at pressures up
to 3000 psi. Depending on the meters selected,
these fixed ratio dispensers can have rather
large capacities. Due to their long 10”
stroke, at a 1:1 volumetric ratio, a maximum
output per stroke of 48.1 in3 is
available. Volumetric Ratios of 1:1 up to 22:1
are attainable through selection of various
sized metering cylinders.
The N-2290 Series dispensers utilize Jesco Roto-Stat
High Shear Dynamic Mixers to provide consistent
and uniform mixed material. They are available
in 3 different sizes and in 1 or 2 port inlet
versions to suit the individual requirements
of an application. For very difficult to mix
epoxy chemistries, the N-2530 Series Roto-Stat
mixer is available. This single port inlet,
3 fl. Oz. capacity mixer has a “Pre-mix”
static mixer element at the inlet of the mixer
chamber. It also has a “Profiled”
inner mix chamber design that virtually guarantees
complete mix with no striations on even the
most difficult to mix epoxy chemistries dispensed
at delivery rates as high as 25 cc per second.
The N-2290 Series dispensers include a PLC control
panel that provides a full complement of Manual
as well as Automatic control functions. Functions
such as Timed Shot, Time Lapse Warning, Auto
Mixed Material Purge, Auto Flush, etc. are all
standard functions and can be adjusted to meet
individual applications.
Several versions of the N-2290 Series dispensers
are available. Some have Volume and Flow Rate
Indicators. Others have Dual Mixer Assemblies
and some have Dual Applicator Guns. Contact
Jesco for details. Chances are, we already have
the feature you require for your application.
