USE
The automatic high-pressure spraying gun EcoGun 651 is intended
to surface treatment of the products by the high-pressure spraying
of commonly used NH, even the water-born materials. During the
work procedure, the sprayed material is atomized under the high-
pressure up to 300 bars. It can be used even for spraying of other
materials, which do not damage the spraying gun materials by their
composition. The gun is designed to remote control by the pressure
air controlled by the three-way electro-magnetic valve. It can be
used for all spraying devices of the VYZA type so-far produced in
Dürr Systems Czech Republic a.s., which do not exceed the HN max.
operating pressure. When other high-pressure devices are to be
used, the operation of the automatic gun must be consulted in the
manufacturing plant in advance. The gun is intended for equipment
of the automatic production lines and enables also interruption of
the spraying regarding the shape of the sprayed object and the
production line cycle. Combination of the high pressure of the NH and
the special high-pressure nozzle results in even layer of the applied
NH with minimum fly-out of small particles to the environment. The
nozzle suitable for the particular application must be selected on
basis of previous tests and recommendation of the manufacturer.
COMMISSIONING
Before commissioning of the gun, the preservation grease must be
removed from the surface by suitable degreaser. Internal section
must be flushed out by the pressure solvent connected to the inlet
angle-adjustable fitting for the NH and opening of the needle valve
with subsequent injection of the pressure control air 5 bar.
Upon cleaning the gun is fitted with suitable high-pressure nozzle or
with the holder fitted with the rotating nozzle. The nozzle is fitted
directly to the cup nut with protecting cover, which forms part of
the gun; the rotating nozzle is fixed to the holder, which is installed
directly to the gun upon screwing of the cup nut with protecting
cover.
The assembled gun is fixed to the manipulator through the holder,
connected to the pressure control air 5 bar through the three-way
electromagnetic valve of flow ca 150 l/min. and the NH supply from
the high-pressure device; then tighten the cut nut on the NH angle-
adjustable fitting. The hose must be electro-static conductive for
transport of the flammable liquids. In case of handling with the NH of
quicker sedimentation rate, which requires circulation, the circulation
high-pressure hose can be connected by unscrewing the plug in the
gun front section and fitting of the NH circulation line (not part of the
supply). The general connection is done acc. to the wiring diagram.
