Ship Pressure Water Tank

Ship Pressure Water Tank | Shipboard Water Pressure Solution

Product Overview: Advanced Marine Frequency Conversion Constant Pressure Water Supply Unit

Our state-of-the-art Ship Pressure Water Tank is engineered to deliver unparalleled performance and reliability for vessel water management. This intelligent system seamlessly replaces traditional ship freshwater and sanitary water tanks, providing a continuous supply of domestically used water and cleaning water with perfectly stable pressure throughout your maritime operations.

How Our Marine Constant Pressure Water System Works

Utilizing cutting-edge pressure sensing technology, our system continuously monitors pipeline water pressure through precision sensors that convert pressure readings into electronic signals. These signals are processed through an advanced PID regulator that compares real-time data against user-defined pressure parameters. The system then automatically adjusts pump motor speeds through frequency conversion technology and manages pump sequencing via programmable logic control (PLC), ensuring optimal water pressure remains constant regardless of demand fluctuations.

① Remote Monitoring & Alarm System

• Integrated fault detection with normally closed/open passive contact interface enables comprehensive remote alarm capabilities for enhanced vessel safety

② Intelligent Water Shortage Protection

• Built-in float level switch automatically suspends operation during low-water conditions, preventing pump damage and providing immediate alert notifications

③ Auto Frequency Conversion Technology

• Smart dual-pump variable frequency operation maintains constant pressure during varying demand

• Automatically activates additional pumps during high consumption periods

• Reduces pump operation during low usage

• Energy-saving sleep mode activation during zero demand

• Instant system wake-up when water demand resumes

④ Power Frequency Operation Mode

• Dual-pump alternating operation with pressure tank functionality ensures uninterrupted water supply

⑤ Single Pump Backup Functionality

• Maintenance-friendly design allows single pump operation during service periods

• Selectable #1 or #2 pump power frequency operation for continuous service

Maintenance Guide & Schedule

Safety First: Always perform maintenance 5 minutes after complete system power shutdown

Routine Maintenance Protocol

• Initial monthly air pressure checks: Verify weekly for first month, then monthly once stabilized

• Proper pressure check procedure: Stop pump → depressurize system to 0 → verify tank pressure (0.12-0.14MPa) using included barometer

• Monthly surface dust removal and cleaning

• Monthly system reset: Complete power cycle (≥5 minutes shutdown) followed by normal restart

Preventive Maintenance Requirements
Immediate shutdown required if these abnormalities are detected:

• Obstructed pump cooling fan – clean immediately

• Excessive motor bearing noise (>80dB friction screeching)

• Abnormal pump/motor temperatures exceeding 55°C – requires immediate investigation
