1. Introduction to top
The APSON Pulse Cleaner CPP-2000 is a pneumatically controllable
rinsing block for aggressive lacquers and solvents. It is the standard
cleanerblock designated for the modular APSON Lacquer Changer
###-2000 M.
The APSON Pulse Cleaner CPP-2000 is particularly suitable for
automatic painting systems with often changing lacquers and serves for
rinsing the lacquer changer switch, the hoses and rotation atomizers or
spray guns. It avoids reliably a pollution of the newly connected lacquer
during the painting process and ensures thus a perfect lacquer
change.
-
Small solvent consumption for perfect rinsing.
-
Environmental careful short rinsing cycle due to high
throughput.
-
Very good rinsing barness due to deathroom-minimized valve
blocks.
-
The valves are compatible with the valves of the lacquer changer
switch blocks.
-
Fast valve exchange due to screwable valve technique.
-
Pro-active maintenance possible due to leakage display of the
valves.
-
Visible switching status of the valves.
-
Small, compact design.
3. Structure and Function to top
The APSON Pulse Cleaner CPP-2000 consists of a block housing with an
output and one input each for solvent LM (LO) resp. compressed air LU. The
output side of the pulse cleaner forms a pressure tight interface to the
valve blocks of the lacquer change-over switch.
A pneumatically controllable valve is assigned to each input. Due to
that alternated control of the two valves, the opening times of the valves
can overlap. Therefore the connection fittings of both inputs (compressed
air and solvent) contain an additional checkvalve each.
During painting, solvent and compressed air pend permanently at the
pulse cleaner. For executing the rinsing cycle, the solvent valve LF and
the compressed air valve LLF are alternatingly opened, starting with the
solvent valve.
Due to this sequence, an alternating flow of air resp. solvent
develops, which rinses reliably the lacquer changer switch downstream the
hoses and other spray devices. The duration of the rinsing cycle as well
as the switching sequence of the two valves depend on the conditions of
the painting process and are to be controlled by means of a programmable
logic controller. The more briefly the switching on impulses of the two
valves (preferably smaller than 1 second), the better the rinsing
quality.
