In addition to storing oil in the hydraulic system, the oil tank of the dredger also plays a role in heat dissipation, separation of bubbles in the oil, and precipitation of impurities. There are many accessories installed in the fuel tank, such as coolers, heaters, air filters (function: filtering impurities, etc.) and level gauges.
Fuel tanks can be divided into open fuel tanks and closed fuel tanks. Open fuel tank, the liquid level in the tank communicates with the atmosphere, and an air filter (function: filtering impurities, etc.) is installed on the fuel tank cover. The open tank has a simple structure and is easy to install and maintain. This type of hydraulic system is generally adopted. Closed oil tanks are generally used for pressure oil tanks, filled with rare gas at a certain pressure, and the inflation pressure can reach 0.05MPa. If divided according to the shape of the fuel tank, it can be divided into rectangular fuel tank and round tank-shaped fuel tank. Rectangular fuel tanks are easy to manufacture and easy to place hydraulic components on the tank, so they are widely used; round tank-shaped fuel tanks have high strength, light weight, and easy cleaning, but they are difficult to manufacture and occupy a large area. They are used in large metallurgy (content: from ore It is often used in equipment for extracting metals or metal compounds.
