Variable Speed Circulation Pump Ink Sedimentation

The circulation pump operates with variable flow velocity rather than constant high speed. The pump dynamically adjusts its operation: operating at high flow velocity during initial circulation to eliminate sedimentation, then switching to low flow velocity for maintenance circulation. This dynamic operation resolves the contradiction by achieving fast sedimentation elimination only when necessary, while reducing power consumption during extended operation periods.

The system implements periodic circulation with two distinct phases: an initial high-velocity phase for sedimentation elimination, followed by a low-velocity maintenance phase. This periodic action pattern allows the system to achieve the benefit of rapid sedimentation removal while minimizing energy consumption during the longer maintenance period, thus resolving the time-power consumption contradiction.

The circulation pump uses dynamic variable-speed operation instead of sustained high-speed operation. High flow velocity is applied only during the initial sedimentation elimination phase, then the pump switches to low flow velocity for maintenance circulation. This dynamic approach eliminates sedimentation quickly when needed while significantly reducing mechanical stress and wear on the pump during extended operation, thereby extending pump life.

The system employs periodic circulation with alternating high-velocity and low-velocity phases. The initial high-velocity phase rapidly eliminates sedimentation, while the subsequent low-velocity maintenance phase minimizes pump wear. This periodic action pattern achieves fast sedimentation elimination while protecting pump longevity through reduced operational stress during extended periods.

The circulation pump operates continuously at low flow velocity during maintenance periods rather than stopping completely. This continuous low-velocity operation prevents sedimentation formation while maintaining operational simplicity. The useful action of circulation continues uninterrupted, eliminating the need for long re-circulation periods after stoppage while keeping the system easy to operate.

The system implements periodic circulation patterns where the pump alternates between high-velocity sedimentation elimination phases and low-velocity maintenance phases. This periodic operation prevents complete sedimentation buildup during maintenance periods while avoiding the complexity of continuous high-speed operation, thus maintaining ease of operation while minimizing circulation time requirements.
