柴油发电机组油箱如何安装 How to install the fuel tank of a diesel generator set

柴油发电机组的油箱到底该如何安装，不同型号的柴油发电机组都有相应的标准油箱和供油系统，油箱的设计种类很多，可根据要求用户设计成各种容量的分立式油箱。用户也可自行设计油箱，在安装柴油发电机组油箱的时候用户需注意以下注意事项：

　　 （1) 油箱存放位置必须安全以防止火灾，油箱或油桶应单独放在看得见的地方，适当离柴油发电机组远点，且严格规定不准吸烟；

　　 （2）如果是用户自行制作油箱，应注意备用柴油发电机组燃油箱用不锈钢或钢板制作，切勿在燃油箱内部喷漆或镀锌，因为他们会与柴油发生化学反应，产生可能引起柴油发电机组损坏的杂质及降低柴油的品质、洁净度和燃烧效率；

　　 （3）油箱放置后，最高油面不能比柴油发电机组底座高出其2.5米，如大油库油面高于2.5米，应在大油库与柴油发电机组之间加日用油箱，使直接送油之压力不大于2.5米。即使在柴油发电机组关闭期间，也不允许燃油依靠重力，通过进油管路或喷油管路流入柴油机；

　　 （4）油口处的阻力不允许超过所有柴油发电机组性能数据单上规定的使用干净滤芯时的规定值。这个阻力值是建立在燃油箱装一半燃油的基础上的；

　　 （5）油箱供油管端位置应高于柴油发电机组油箱底部约50MM，以防止沉积物和水被吸入供油管；

　　 （6）燃油回油管路的连接不应造成柴油发电机组油管中燃油出现冲击波；

　　 （7）油箱内装的燃油容量应该保证每天的日常供应；

　　 （8）油箱供油和回油区域应设有带孔隔板，以减少柴油发电机组的热交换。

How to install the fuel tank of a diesel generator set? Different models of diesel generator sets have corresponding standard fuel tanks and fuel supply systems. There are many types of fuel tank designs, and users can design them into various capacity discrete fuel tanks according to their requirements. Users can also design their own fuel tanks. When installing diesel generator fuel tanks, users should pay attention to the following precautions:

(1) The storage location of the fuel tank must be safe to prevent fires. The fuel tank or tank should be placed separately in a visible place, appropriately far away from the diesel generator set, and smoking is strictly prohibited;

(2) If the user makes the fuel tank themselves, they should pay attention to using stainless steel or steel plates to make the fuel tank for the backup diesel generator set. Do not spray paint or galvanized the inside of the fuel tank, as they will react chemically with diesel, producing impurities that may cause damage to the diesel generator set and reduce the quality, cleanliness, and combustion efficiency of diesel;

(3) After placing the fuel tank, the highest oil level should not be higher than 2.5 meters above the base of the diesel generator set. If the oil level in a large oil depot is higher than 2.5 meters, a daily fuel tank should be added between the large oil depot and the diesel generator set to ensure that the pressure of direct fuel delivery does not exceed 2.5 meters. Even during the shutdown period of the diesel generator set, it is not allowed for fuel to flow into the diesel engine through the inlet or injection pipelines by gravity;

(4) The resistance at the oil outlet shall not exceed the specified value when using a clean filter element as stated on the performance data sheet of all diesel generator sets. This resistance value is based on the assumption that the fuel tank is filled with half of the fuel;

(5) The position of the fuel supply pipe end of the fuel tank should be about 50MM higher than the bottom of the diesel generator tank to prevent sediment and water from being sucked into the fuel supply pipe;

(6) The connection of the fuel return pipeline should not cause shock waves in the fuel pipes of the diesel generator set;

(7) The fuel capacity inside the fuel tank should ensure daily supply;

(8) The fuel supply and return areas of the fuel tank should be equipped with perforated partitions to reduce heat exchange in the diesel generator set.
