[0002] The fuel tank, i.e. the fuel storage device, has high requirements for corrosion resistance. At double working pressure, it should be sealed when the gauge pressure is at least 0.03MPa. The generated overpressure must be reduced by itself through the hole or safety valve. When driving on a curve, inclined road or impacted, the fuel should not flow out from the sealing cover or pressure balance device for filling. The fuel tank must be installed away from the engine to avoid ignition of the fuel in the event of a traffic accident. In addition to storing oil, the fuel tank in the hydraulic system also plays a role in heat dissipation, separation of bubbles in the oil, and precipitation of impurities.
