Pulse Cleaner 2000
1. Introduction
The APSON Pulse Cleaner 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 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.
2. Structure and Function
The APSON Pulse Cleaner 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 connetion 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.
3. Features
-
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.
