Why Daily Checks Matter
A fuel oil purifier runs continuously for many hours in the engine room. Even a small problem like low temperature, wrong interface, or vibration can reduce separation efficiency and damage the engine. Therefore, routine daily checks are essential to ensure safe and trouble-free operation.
In practice, every watchkeeping engineer must monitor the purifier just like any other critical machinery.
This guide explains the exact checks to be carried out during each watch.
Pre-Start Visual Inspection (Before Running)
Before starting the purifier, quickly inspect:
- No oil leakage around bowl or outlets
- Lube oil level normal
- Operating and sealing water available
- Heater working properly
- No abnormal noise or loose parts
- Sludge tank ready for discharge
Checks During Operation (Every Watch)
While the purifier is running, monitor the following:
Temperature of fuel oil
Maintain around 98–104°C.
Low temperature increases viscosity and reduces separation.
Bowl speed or motor load
Ensure purifier reaches rated speed.
High current may indicate overload or sludge buildup.
Oil discharge clarity
Clean oil should look bright and clear.
Cloudy oil indicates water contamination.
Water outlet observation
Check for oil loss through water line.
Oil in water means wrong interface or gravity disc.
Pressure and flow rate
Maintain correct throughput as per maker’s manual.
Too high flow reduces efficiency.
Vibration and noise
Abnormal vibration may indicate imbalance or dirty bowl.
Sludge discharge interval
Confirm desludging occurs at correct time automatically.
Once Per Watch – Physical Checks
youshould also:
- touch bearing housing for overheating
- check for unusual smell or burning
- inspect foundation bolts
- confirm no excessive leakage
- verify control panel alarms
These checks take only a few minutes
End of Watch Routine
Before handing over the watch:
- record temperature and pressure
- note desludging performance
- mention any abnormalities
- inform next engineer if any issue exists
Proper log keeping helps troubleshooting.
Common Problems Found During Daily Checks
During routine inspection, you may notice:
- water in clean oil
- excessive vibration
- frequent alarms
- sludge not discharging
- overheating motor
Immediate action prevents serious damage.
