3 DESCRIPTION OF UNIT
3.1
AIRLESS PROCESS
The main area of application are thick layers of highly viscous
coating material.
At the Eiite 3000 unit a diaphragm pump takes in the coating
materials and transports it via a high-pressure hose to the spray
gun with the airless tip. Here the coating material atomizes
since it is pressed through the tip core at a maximum pressure
of 3300 PSI (22.8 MPa). This high pressure has the eect of
micro ne atomisation of the coating material.
As no air is used in this process, it is described as an AIRLESS
process.
This method of spraying has the advantages of nest
atomisation, cloudless operation (depending of a correct unit
adjustment) and a smooth, bubblefree surface. As well as these,
the advantages of the speed of work and convenience must be
mentioned.
3.2 FUNCTIONING OF THE UNIT
The following section contains a brief description of the
technical construction for better understanding of the function:
The Eiite 3000 is an electrically driven high-pressure paint
spraying equipment.
The electric motor (1) drives the hydraulic pump via planetary
gears (2). A piston (3) is moved up and down so that hydraulic
oil is moved under the diaphragm (4) which then moves.
In detail:
The downwards movement of the machine opens the disk inlet
valve (5) automatically and coating material is sucked in.
During the upwards movement of the diaphragm, the coating
material is displaced and the outlet valve opens while the inlet
valve is closed.
The coating material ows under high pressure through the
high-pressure hose to the spray gun and is atomized when it
exists from the tip.
The pressure control valve limits the set pressure in the
hydraulic oil circuit and thus also the pressure of the coating
material.
A pressure change when the same tip is used also leads to a
change in the amount of paint atomized.
