1. Introduction to top
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 change-over 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 with
constant 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 to top
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 change-over
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
change-over 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.
-
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
change-over 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.
