Operational Principle – Automated Pressure Maintenance

Initial Filling: Water pump supplies freshwater or seawater into the tank until visible in the glass water gauge
Pressure Building: Air compressor supplies compressed air until pressure reaches 0.25 MPa
Automatic Pump Operation:
- Pump automatically stops when pressure reaches 0.4 MPa (via pressure relay)
- Pump automatically restarts when pressure drops to 0.25 MPa (via pressure relay)
Continuous Cycle: System maintains consistent pressure without manual intervention
