Due to the special nature of the excavator, its operating environment is usually outdoors in a relatively harsh environment. Soil, sand and surrounding environment are often arduous. So this is a serious challenge to the maintenance of the excavator. We should not only improve our sense of maintenance in daily life, but also pay attention to it in the course of homework. We must guard against the consequences of bad operations caused by all unfavorable factors.
Today Xiaobian will lead you to learn. How to maintain the normal operation of the diesel oil tank in the field operation. When the oil tank is not sufficient to supply the oil, it needs to be refueling immediately. As it is in the operation, the oil is usually added to the operation. It is necessary to clean the environment around the machine so as to prevent the contamination in the oil input process.
At the end of the day's operation, the tank oil should be added to the full tank so that the water droplets from condensation inside the tank can be mixed with diesel in the tank. At the same time, the oil drain drain valve should be opened before daily operation. The dirt, grease and moisture discharged from the bottom of the tank should be discharged.
In the process of machine operation, the oil quantity in the tank should be mastered at any time. The oil should be added in time when the oil is short, so as to prevent the oil or air from the bottom of the box to enter the fuel system. The ventilation hole of the tank shall be unblocked in time. Once the blockage occurs, the negative pressure will be formed in the box, and the pressure of the oil delivery and the amount of oil supply will be reduced. The power of the diesel engine can not be fully utilized.
Attention should be paid when leakage or switch off is tight. If not handled properly, it is easy to cause environmental pollution and fire hazards. At this point, it is necessary to stop welding or repair and replace the switch. Do not continue to work. Otherwise, the leakage will become more and more serious under the vibration of the machine.
When the machine is used for a long time, the diesel oil in the fuel tank comes into contact with the moisture in the air and contacts with the inner wall of the fuel tank, resulting in certain fouling. One part of the dirt falls into the bottom of the box. The other part is attached to the box wall. Therefore, the machine should clean the tank once every work 1500~2000h.. Otherwise, even if the new diesel oil is added, the dirt will be contaminated by its dirt because the dirt in the box is not properly treated.
