In modern ship operations, the purifier on board ship is an indispensable core device in the fuel and lubricant oil treatment system. Its main function is to remove water, impurities, and contaminants from fuel oil through centrifugal separation technology to ensure the stable operation of the engine, reduce wear and tear, and improve fuel efficiency.
The operation of the purifier on board ship is based on the principle of density difference. By generating centrifugal force through high-speed rotation, impurities and water with higher density are thrown to the outside, while the lighter fuel oil is concentrated in the center, thus achieving effective fuel purification.
Its core working steps include:
Fuel heating: Before entering the purifier on board ship, the fuel is usually preheated to lower viscosity and improve separation efficiency.
Centrifugal separation: The fuel enters the high-speed rotating separation disc; heavier water and impurities are thrown to the outer wall and discharged, while pure fuel flows to the center and is sent to the oil storage system.
Gravity disc adjustment: According to the different densities of the fuel, select an appropriate gravity disc to optimize the separation effect.
To maintain the optimal operating condition of the purifier on board ship, attention should be paid to the following important factors:
Fuel temperature: The temperature of the fuel before entering the purifier should be maintained at the optimal level, usually between 90-98℃, to reduce viscosity and improve separation efficiency.
Feeding speed: It is recommended to operate multiple purifiers in parallel with the minimum feeding speed to ensure thorough fuel purification.
Gravity disc selection: Choose a gravity disc suitable for the fuel density to enhance impurity separation effect and prevent abnormal purifier operation.
Regular cleaning and maintenance: Filters and heaters should be cleaned regularly according to the planned maintenance system of the ship or the manufacturer's recommendation to prevent clogging that affects the purification effect. Fuel tanks should be cleaned regularly to reduce sediment accumulation and avoid fuel contamination.
To ensure the long-term stable operation of the purifier on board ship, daily maintenance and management must be performed, including:
Regularly clean the purifier: When the fuel quality is poor, the purifier should be cleaned more frequently to prevent high concentrations of impurities and sediments from damaging the equipment.
Ensure normal operation of the fuel filtration equipment: Never bypass the fuel filtration system, as this may cause damage to the main and auxiliary engines.
Fuel sample testing: Regularly send fuel samples to certified fuel laboratories for testing to ensure fuel quality meets standards.
Adequate spare parts: The ship should be equipped with enough spare parts to promptly replace damaged components during the voyage, avoiding operation interruptions due to equipment failure.
In the modern shipping industry, the purifier on board ship is crucial for fuel management. By optimizing the fuel treatment process, it can effectively reduce engine wear, lower fuel consumption, and improve fuel efficiency. Moreover, in addressing water, aluminum, silicon, and other impurities in the fuel, the purifier can significantly reduce their concentration, ensuring that the fuel meets engine usage standards, thus extending equipment life and reducing maintenance costs.
Overall, the correct use and maintenance of purifier on board ship can not only ensure the purity of the ship's fuel supply but also enhance ship operation efficiency, reduce unexpected failures, and provide strong support for the safe operation of the ship.
