This article introduces the design of a type of ship fuel stabilized filtration and supply system, which aims to safely provide clean and stable fuel. Through research on the ship fuel oil supply system, a ship fuel oil supply system with stabilizing and filtering function was designed, including components such as the cabin, oil storage tank, main output pipe, refueling pipe, refueling and maintenance port, and slag discharge port. This system can achieve pressure regulation inside the cabin, ensuring the stability of fuel supply pressure. It has the function of stabilizing fuel pressure and filtering impurities, and removes impurities from the fuel through filtration to reduce impurities entering the suction and output pipes. The use of this system can effectively improve the quality of ship fuel supply, improve ship operation efficiency and safety, and has high practical application value.
