Operating Principle
The ZYG(S) Marine Hydrophore System maintains a constant water pressure through the application of compressed air technology. The vortex pump is responsible for delivering water into the pressurized tank, where compressed air is used to keep the system pressure within the range of 0.3 – 0.4 MPa. The automatic pressure controller plays a crucial role in regulating the operation of the pump, ensuring that it activates when the pressure drops to 0.3 MPa and stops when the pressure reaches 0.4 MPa. Additionally, several safety systems are in place to guarantee reliable performance:
- Liquid Level Gauge: Offers a clear visual indication of the water levels inside the tank, allowing operators to monitor the water supply status.
- Pressure Gauge: Continuously monitors the system pressure in real – time, providing instant feedback on any pressure fluctuations.
- Automatic Pressure Control: Automatically activates the pump at 0.3 MPa and stops it at 0.4 MPa, maintaining a stable water pressure within the system.
- Safety Valve Protection: Releases pressure that exceeds 0.42 MPa, preventing potential damage to the system due to over – pressurization.
- Dual Control Modes: Provides both manual and automatic operation options, giving operators the flexibility to choose the most suitable control method based on the specific situation.
Maintenance & Service Guidelines
Regular Inspection Checklist
- Thoroughly check all pipeline connectors and valves for tightness to prevent the intrusion of air into the system, which could affect the water pressure and system performance.
- Verify the integrity of the charge valve and ensure proper sealing to prevent leaks and maintain the correct amount of compressed air in the system.
- Regularly monitor the system pressure and add compressed air if the pressure remains consistently low, ensuring that the system operates within the designed pressure range.
- Inspect the settings of the pressure controller and the pump activation parameters to ensure that they are correctly configured for optimal system performance.
Periodic Maintenance
- Conduct regular tank cleaning and interior inspection to remove any sediment, debris, or contaminants that may accumulate over time, ensuring the cleanliness and proper functioning of the tank.
- Repaint the interior of the tank based on an assessment of the coating condition to prevent corrosion and maintain the structural integrity of the tank.
- Perform maintenance on the exterior anti – corrosive coating to protect the tank from the harsh marine environment and extend its service life.
- Replace wear parts during scheduled dry docking to prevent unexpected failures and ensure the reliable operation of the hydrophore unit.
- Maintain the pump according to the manufacturer’s specifications, including regular lubrication, cleaning, and replacement of worn – out components.
Safety Considerations
- Always depressurize the system before performing any maintenance tasks to avoid the risk of injury from high – pressure water or compressed air.
- Follow lockout/tagout procedures during servicing to prevent accidental activation of the system and ensure the safety of maintenance personnel.
- Use appropriate personal protective equipment, such as gloves, safety glasses, and protective clothing, to protect against potential hazards during maintenance operations.
- Maintain proper ventilation during interior maintenance to prevent the accumulation of harmful gases and ensure a safe working environment.
