1) Diesel oil should be precipitated for more than 48 hours before being added to the fuel tank to prevent impurities in the oil from being brought into the fuel tank.
2) The vent hole on the fuel tank cover should be dredged frequently. Once blocked, negative pressure will be formed in the tank, reducing the fuel delivery pressure and reducing the fuel supply, so that the power of the diesel engine cannot be fully utilized.
3) The amount of fuel in the fuel tank should be known at all times during the machine operation, and the fuel should be added in time when the fuel is short, to prevent running out of fuel and causing dirty oil or air at the bottom of the tank to enter the fuel system, thereby affecting the normal operation of the diesel engine.
4) After the machine is stopped, the fuel tank should be filled with oil to avoid condensation on the inner wall of the fuel tank at night to prevent water droplets from flowing into the diesel oil. In addition, before starting work, the drain valve of the fuel tank should be opened to drain the dirty oil or water deposited at the bottom of the tank.
5) Leaking fuel tanks or poorly closed switches will pollute the environment, easily cause fires, waste diesel fuel, and increase operating costs. At this time, the machine should be shut down for repair or replacement of the switch, and the operation must not be forced to continue, otherwise, the leakage under the vibration of the machine will become more and more serious and cause greater losses.
6) After long-term use of the diesel generator set, the diesel in the fuel tank will generate dirt when it comes in contact with the air or the tank wall. In the process of refueling every day, dust or moisture will inevitably be brought into the fuel tank. Therefore, the fuel tank should be cleaned every 1500~2000h of the machine, otherwise, it will be contaminated even if all clean diesel is added.
