Technical Field

The invention relates to the technical field of marine fuel oil supply, in particular to an marine fuel oil supply system with a filtering function.

Background

Ships, a collective term for various ships. A ship is a vehicle which can be sailed or moored in a water area for transportation or operation, and has different technical performances, equipment and structural types according to different use requirements.

The shape is favorable for overcoming the linear envelope of flow of fluid resistance, the material is continuously updated along with technological progress, the material is natural materials such as wood, bamboo, hemp and the like in the early stage, and the material is mostly steel, aluminum, glass fiber, acrylic and various composite materials in recent times.

Ocean-going large ships, which open up water channels among countries in the world, are mostly powered by fuel oil, which is easier to store and transport than coal and cheaper. In the metallurgical industry, fuel oil can also be used to replace coke for metal smelting. The fuel oil sources are mainly vacuum residuum and cracked residuum. The fuel oil has low viscosity and low condensation point, so that the fuel oil can be used with or without preheating.

The marine fuel oil needs to strictly control mechanical impurities, otherwise, an oil way, an oil filter or a nozzle can be blocked, so that the ship can be stopped midway, and even dangerous accidents can happen. The fuel oil with poor stability can block an oil supply pipeline due to the deposited asphalt colloid oil sludge, or the fuel oil pump or a nozzle can not be started after the engine is stopped, and the conventional marine fuel oil supply system does not have a filtering function on the fuel oil when in use, so that the normal suction and use of the fuel oil are influenced.
