发电机燃油箱的作用 The function of the generator fuel tank

        电能是现代社会最主要的能源之一。发电机是将其他形式的能源转换成电能的机械设备，它由水轮机、汽轮机、柴油机或其他动力机械驱动，将水流，气流，燃料燃烧或原子核裂变产生的能量转化为机械能传给发电机，再由发电机组转换为电能。柴油发电机在工农业生产，国防，科技及日常生活中有广泛的用途。

        燃油箱，即燃油贮存装置，对耐腐蚀性要求高。在双工作压力时，在表压至少是0.03MPa时应密封。产生的过压力必须通过孔或安全阀自行减压。在弯道行驶、倾斜路面或受到冲击时燃油不应从加液的密封盖或压力平衡装置流出。燃油箱必须离开发动机安装，以免在出现交通事故时点燃燃油。

        燃油箱在液压系统中除了储油外，还起着散热、分离油液中的气泡、沉淀杂质等作用。燃油箱有开式油箱和闭式油箱二种。开式油箱结构简单，安装维护方便，液压系统普遍采用这种形式；闭式油箱一般用于压力油箱。

燃油箱一般设有两个出口：一个是我们直接可以看到的燃油加注口，一个是用来装入燃油泵和燃油计量装置的出口。

燃油箱是个相对密闭的系统，油箱上通常设有通风装置，以防止随着油量的过度消耗而再箱内与大气的压力差的作用下变形。早期的燃油箱大多由金属材料制成，后来多改用合成材料以满足轻量化及结构设计的要求。

Electricity is one of the most important energy sources in modern society. A generator is a mechanical device that converts other forms of energy into electrical energy. It is driven by water turbines, steam turbines, diesel engines, or other power machinery to convert the energy generated by water flow, air flow, fuel combustion, or nuclear fission into mechanical energy and transmit it to the generator, which then converts it into electrical energy. Diesel generators have a wide range of applications in industrial and agricultural production, national defense, technology, and daily life.

The fuel tank, also known as the fuel storage device, requires high corrosion resistance. At dual working pressure, it should be sealed when the gauge pressure is at least 0.03MPa. The generated overpressure must be self reduced through holes or safety valves. Fuel should not flow out from the sealing cap or pressure balancing device when driving on bends, sloping roads, or under impact. The fuel tank must be installed away from the engine to avoid igniting the fuel in case of a traffic accident.

In addition to storing oil, the fuel tank also plays a role in dissipating heat, separating bubbles, and settling impurities in the hydraulic system. There are two types of fuel tanks: open fuel tanks and closed fuel tanks. Open type fuel tanks have a simple structure and are easy to install and maintain, and are commonly used in hydraulic systems; Closed fuel tanks are generally used for pressure fuel tanks.

A fuel tank generally has two outlets: one is the fuel filling port that we can directly see, and the other is the outlet used to install the fuel pump and fuel metering device.

The fuel tank is a relatively closed system, usually equipped with ventilation devices to prevent deformation due to the pressure difference between the tank and the atmosphere caused by excessive consumption of fuel. Early fuel tanks were mostly made of metal materials, but later synthetic materials were used to meet the requirements of lightweight and structural design.
