1. Introduction

^  0  1  2  3  4  5  6 
The APSON Secondary-Circuits Rinsinggroup 2000 serves to divide long lacquer lines into individual rinsing segments. The resulting shorter segments can be rinsing cleaned simultanely and independently. This leads to substantially shorter rinsing cycles and to more flexible rinsing concepts.
APSON Secondary-Circuits Rinsinggroup 2000 - standard configuration
The APSON Secondary-Circuits Rinsinggroup 2000 is particularly suitable for applications in automatic systems for the processing of lacquers, solvents, caustic solutions, a.o.

2. Structure

^  0  1  2  3  4  5  6 
A APSON Secondary-Circuits Rinsinggroup 2000 in standard configuration is build of:
The rinsing block in standard execution has two pneumatically controllable 2/2-ways valves and two checkvalves. As rinsing block alternatively installable types:
The switching block has as standard a pneumatically controllable 3/2-ways valve for the lacquer enable resp. lacquer feedback. For special applications, e.g. preloadeable A-B systems, the switching block is optionally available with an additional 3/2-ways valve.

3. Function

The following scheme shows an exemplaric Concept for lacquer supply with a Secondary-Circuits Rinsinggroup SSG.
The SSG divides the paint line mainly in two segments:

Legend

  • Secondary-Circuits Rinsinggroup SSG (segment III): B1 = rinsing block, B2 = switching block, LS = secondary circuit solvent, PLS = secondary circuit pulsing air, FFS = secondary circuit lacquer enable.
  • Pump block PB (in segment II): P = rinseable gearing pump, F = paint line from the lacquer changer.
  • Pump rinsinggroup PSG (in segment II): LP = pump group solvent, PLP = pump group pulsing air, RFP = pump group feedback, BYP = pump group bypass-valve.
  • Lacquer changer FW with own rinsing block (segment I): LF = lacquer changer solvent, PLF = lacquer changer pulsing air, FFF = lacquer changer lacquer enable, Fx = lacquer 1 to lacquer N.
  • Other Symbols: L = solvent line, DR = pressure regulator, AB = receptacle, RF = feedback, K = ball-valve, R = checkvalve, Z = atomizer.
The following mainly describes segment III with SSG. Segments I and II are provided only for better understanding of the following text.
During the painting process the feedback link of the switching block FFS is closed. The lacquer flows thus through FFS to the atomizer Z.
During the rinsing cycle the APSON Cleaner of the lacquer changer LW becomes active and the 3/2-ways valve of the switching block FFF switches the supply sided hose segment over its feedback link to the likewise receptacle AB. The APSON Cleaner of the APSON Secondary-Circuits Rinsinggroup SSG becomes simultaneous active and rinses the mixture from lacquer, air and solvent of the atomizer-sided hoses of segment III over the feedback valve of the atomizer Z into the likewise receptacle AB.
