4 major management of excavator

1. Fuel management

 Different grades of diesel should be selected according to different ambient temperatures; diesel cannot be mixed with impurities, dirt and water, otherwise it will wear the fuel pump prematurely; the high content of paraffin and sulfur in poor-quality fuel will cause damage to the engine; daily operation After the fuel tank is finished, the fuel tank should be filled with fuel to prevent water droplets on the inner wall of the fuel tank; the drain valve at the bottom of the fuel tank should be opened to drain water before daily operation; after the engine fuel is exhausted or the filter element is replaced, the air in the road must be drained.

 

2. Management of other oils

 Other oils include engine oil, hydraulic oil, gear oil, etc.; different brands and different grades of oil cannot be mixed; different types of excavator oils add different chemical or physical additives during the production process; ensure that Clean with oil to prevent the mixing of impurities (water, dust, particles, etc.); choose the oil label according to the ambient temperature and purpose. If the ambient temperature is high, the oil with high viscosity should be used, and the oil with low viscosity should be used when the ambient temperature is low; the viscosity of the gear oil is relatively large to adapt to the large transmission load, and the viscosity of the hydraulic oil is relatively small to reduce liquid flow resistance.

 

3. Lubricating grease management

 The use of lubricating oil (butter) can reduce the abrasion of the moving surface and prevent noise. When the grease is stored and kept, dust, sand, water and other impurities should not be mixed in, and it is suitable for heavy-duty working conditions; when filling, all the old oil should be squeezed out and wiped clean to prevent sand and soil adhesion.

 

4. Maintenance of filter element

 The filter element plays the role of filtering impurities in the oil circuit or gas circuit to prevent it from entering the system and causing failure; various filter elements should be replaced regularly in accordance with the requirements of the (operation and maintenance manual); when replacing the filter element, check whether there is metal attached to the old If metal particles are found on the filter element, diagnose in time and take improvement measures; use the pure filter element that meets the machine regulations. The filter capacity of the fake filter element is poor, and the material quality of the filter layer does not meet the requirements, which will seriously affect the normal use of the machine.
