Equipment Description and Component Identification
15. Electric Solenoid Valve Assembly
The Electric Solenoid valve assembly distributes positive pressure
and vacuum to each connector and Electric Solenoid valve.
(Figure 3-8)
16. Ink Supply Electric Solenoid Valve
Turn on the ink supply Electric Solenoid valve and then the ink in
the ink supply pump and the main ink filter is able to reach ink
pressure gauge and printhead. (Figure 3-7 & 3-8)
17. Makeup Ink Electric Solenoid Valve
The Makeup ink Electric Solenoid valve controls flush pump to
add Makeup ink from Makeup ink tank when the viscosity
coefficient is above the initialization to adjust the viscosity to a
normal level. (Figure 3-7 & 3-8)
18. Cleaning Electric Solenoid Valve
Turn on the cleaning Electric Solenoid valve and then makeup ink
in the makeup pump will reach the printhead and complete clean
automatically. (Figure 3-7 & 3-8)
19. Churn Electric Solenoid Valve
After turning on the churn Electric Solenoid valve, the circulation
pump will absorb the ink in the ink tank to the viscosimeter, and
then from viscosimeter back to the ink tank to complete churning
the ink. (Figure 3-7 & 3-8)
20. Circulation Electric Solenoid Valve
Turn on the circulation Electric Solenoid valve, and then recycle
pump will absorb the ink in ink supply pipe back to ink tank to
complete the air release of ink supply pipe. (Figure 3-7 & 3-8)
21. Pressure Release Electric Solenoid Valve
After turning on the pressure release Electric Solenoid valve,
recycle pump will absorb the ink in the ink supply pump and main
ink filter back to ink tank to complete ink pressure release and
shut the ink stream quickly. (Figure 3-7 & 3-8)
22. Recovery Electric Solenoid Valve
Turn on the Recovery Electric Solenoid valve and then recovery
pump returns the un-used ink from printhead to the ink tank.
