3 DESCRIPTION OF UNIT
3.1
AIRLESS PROCESS
The main areas of application are thick layers of highly viscous
coating material for large areas and a high consumption of
material.
A piston pump takes in the coating material by suction and
conveys it to the tip. Pressed through the tip at a pressure of
up to a maximum of 221 bar (22.1 MPa), the coating material
is atomised. This high pressure has the eect 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 and a smooth, bubble-free
surface. As well as these, the advantages of the speed of work
and convenience must be mentioned.
3.2 FUNCTIONING OF THE UNIT
In the following there is a short description of the technical
construction for better understanding of the function.
Wagner PS 3.29 / 3.31 units are electrically driven high-pressure
spraying units.
A gear unit transfers the driving force to a crankshaft. The
crankshaft moves the pistons of the material feed pump up and
down.
The inlet valve is opened automatically by the upwards
movement of the piston. The outlet valve is opened when the
piston moves downward.
The coating material ows under high pressure through the
high-pressure hose to the spray gun. When the coating material
exits from the tip it atomizes.
The pressure control knob controls the volume and the
operating pressure of the coating material.
