How to maintain the oil for the telescopic boom excavator

The purpose of regular maintenance on telescopic boom excavator is to reduce machine failures, extend machine life, shorten machine downtime, improve work efficiency, and reduce operating costs. As long as the fuel, lubricating oil, water and air are managed well, 70% of failures can be reduced. How can we manage fuel, lubricating oil, water and air?

1. Fuel management

Different grades of diesel should be selected according to different ambient temperatures; diesel cannot be mixed with impurities, dust 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, you should choose a high-viscosity oil, and when the ambient temperature is low, you should choose a low-viscosity oil; the viscosity of gear oil is relatively large to adapt to a large transmission load, and the viscosity of 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, it should not be mixed with dust, sand, water and other impurities; it is recommended to use lithium-based grease G2-L1, which has good anti-wear performance and is suitable for heavy-duty conditions; when refilling, try to squeeze all the old oil Remove and wipe clean to prevent sand and soil from sticking.

4. Maintenance of filter element

The filter element plays the role of filtering impurities in the oil or gas circuit, preventing 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 filter element , If metal particles are found, timely diagnose and take improvement measures; use pure filter elements that meet the machine regulations. The filtering capacity of the fake and inferior filter element is poor, and the surface and material quality of the filter layer do not meet the requirements, which will seriously affect the normal use of the telescopic boom excavator machine.
