Because operators are busy and tired in daily work, it is easy to ignore some details of daily maintenance. It is customary to wait until the machine breaks down before carrying out maintenance. In fact, the failure of daily small parts not only affects the operation of the component itself, but also affects the work of related parts. Therefore, routine maintenance is more important than troubleshooting. The maintenance of excavator mainly focuses on the power system and hydraulic circulation system. The power system is the source of energy output of the excavator. Therefore, if the power system of the excavator fails, it will directly affect the normal operation of the excavator. The daily maintenance of the power system can be divided into oil filter, oil-water separator, diesel filter, air filter element, engine coolant and radiator. This article will explain the role of diesel filter and air filter element and the importance of daily maintenance.
1. Diesel filter
The purity of diesel directly affects the service life of the engine, especially the requirements for diesel quality of the third EFI diesel engine in China are relatively high. Therefore, it is very important to maintain the diesel oil filtration and ensure the oil quality. It is recommended to add diesel oil at regular gas stations. If it is necessary to add diesel oil by yourself during the work, make sure that the refueling area is clean and tidy, and do a good job of diesel sedimentation and filtration. The most important thing is to remember to check and replace the diesel filter element every time you perform routine maintenance.
2. Air filter element
The air intake system of the engine is mainly composed of air filter element and air inlet duct. Clean the air filter element regularly according to different use conditions. High pressure air can be used to blow out the dust in the filter element from the inside to the outside. As the air filter element is made of paper, the air pressure shall not be too high during blowing to avoid damaging the filter element. The air filter element must be replaced after three times of cleaning and cannot be used for a long time.
