Tiedou Excavator Structure and Accessories Introduction (5)

　　In recent issues, we have introduced many structures and accessories of excavators. This issue will continue to introduce the vulnerable accessories of excavators and related precautions. For many users, they may be more concerned about the brand or parameter configuration of the excavator in the early stage. In addition to the hardware differences, the performance gap between brands of an excavator is actually very small, and the service life is the key to later maintenance. So what should we pay attention to when using and maintaining various accessories of the excavator?

　　1. Hydraulic filter element

　　The function of the hydraulic filter element is to filter impurities in the hydraulic oil. The cleanliness of the hydraulic oil during the operation of the excavator will directly affect the operation of each core assembly. In addition to the daily work that will cause a certain amount of particulate matter to penetrate into the hydraulic oil, damage or leakage of the hydraulic oil seal will also cause mud and sand to penetrate into the hydraulic system. In addition to foreign objects, equipment operation, aging of the hydraulic oil pipe and internal wear and tear debris will also cause hydraulic oil contamination. Simple replacement For replacement, it is recommended to use pipe sections or filter elements provided by the official.

　　2. Oil pipe

　　This is an accessory that can be seen everywhere in excavators, supporting the task of transporting hydraulic oil for the entire excavator. Driving hydraulic components, excavators work for a long time, whether it is pressure or temperature is very high, and due to wear and aging in the external environment, regular inspection and replacement are required. The appearance oil pipe is simple to replace, and individuals can easily solve it with the help of tools. Pay attention to avoid oil and pollutants entering the hydraulic oil channel during replacement, and replace the seal ring at the same time.

　　3. Slewing bearing

　　This is the largest gear module in the excavator. This is also the complicated replacement of the vulnerable parts in the excavator after problems occur. In addition to the need for equipment, professional technicians are also required. It is mainly responsible for the 360° rotation of the excavator body. The load pressure during use is high, and high-speed rotation and emergency stop will cause wear. In addition to regular lubrication, it is also necessary to regularly clean the surrounding silt or sand and gravel during use to avoid infiltration and wear. If looseness and gaps in the body are found, it is difficult to repair except replacing the slewing bearing. The failure rate and precision of later processing and repair are difficult to guarantee.

　　4. Air filter and fuel filter

　　This is consistent with the working nature of the filter in the car. The working environment of the excavator is poor, and there are many air pollutants, especially dust and other types of magazines. The air filter needs to be customized and checked. The air filter of the excavator is large, and it is usually equipped with two layers of inner and outer filters to ensure that the pollutants can be excluded. It is simple to replace, and there are many brands. Users can choose according to their own situation. The replacement of the fuel filter is particularly important. In the current design and use of excavator engines, in addition to regular inspection and replacement of fuel filters, try to choose the official filter as much as possible. If there is a problem, the cost of later maintenance is very high.

　　Tiedou used excavator trade network can provide various brands and models of excavator accessories and consumables. In addition to the free one-year standing consumables, the excavator model can be installed and modified according to different types of work needs to meet the user's use requirements. In addition to personal experience, problems that may arise in the daily use of the excavator should be excluded as much as possible. Consult the seller or professional engineer for troubleshooting.
