Turbo-Pulse Cleaner 2001
1. Introduction
The APSON Turbo-Pulse Cleaner 2001 is a pneumatically
controllable rinsing block for aggressive lacquers and solvents.
It is an optionally available cleaner block for the modular APSON
Lacquer Changer 2000 M and is particularly suitable for
automatic painting systems with often changing lacquers.
It serves for rinsing the lacquer changer switch, the hoses
and rotation atomizers or spray guns.
This cleaner type is an advancement of the APSON Pulse
Cleaner 2000 and is optimized for economical solvent
consumption at the same rinsing quality.
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 Turbo-Pulse Cleaner 2001 consists of a block
housing with an output and one input each for
solvent LO resp.
compressed air LU.
The output side of the Turbo-Pulse Cleaner forms a pressure tight
interface to the valve blocks of the lacquer
changer switch.
A pneumatically controllable valve is assigned to each input.
To ensure a safe function of the Turbo-Pulse Cleaner the pressure
at the solvent input must be approx. 1 to 1.5 bar greater
than the pressure at the compressed air input.
Therefore the fitting for the compressed air input is provided
with an additional check valve.
During painting, solvent and compressed air pend permanently
at the turbo-pulse cleaner.
If a rinsing cycle is to be initiated,
then with still closed compressed air valve LLF first the solvent
valve LF is opened.
Briefly afterwards the compressed air is released for the entire
duration of the rinsing cycle.
With opened compressed air valve the flow of the solvent is then
periodically interrupted and released again in short time intervals.
At the end of the rinsing cycle, the air flow as well as the solvent
flow are stopped.
Due to this sequence, a pulsating media flow from air-sputtered
solvent develops, which reliably rinses downstream the
lacquer changer switch, the hoses and other spray devices.
The duration of the rinsing cycle as well as the switching
frequency of the solvent valve depend on the conditions of the
painting process and has to be controlled by means of a
programmable logic controller.
The more briefly the switching-on impulses of the solvent valve
(preferably smaller than 1 second), the better the
rinsing quality.
3. Features
-
Smaller solvent consumption than the
APSON Pulse Cleaner 2000.
-
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
indication of the valves.
-
Visible switching status of the
valves.
-
Small, compact form.
