The purpose of regular maintenance on the excavator is to reduce machine failures, extend machine life, reduce machine downtime, increase work efficiency, and reduce operating costs.
By managing fuel, lubricants, water and air, you can reduce your failure by 70%. In fact, about 70% of the failures are caused by poor management.
1. Fuel management should use different grades of diesel oil according to different environmental temperatures; diesel oil should not be mixed with impurities, lime soil and water, otherwise the fuel pump will wear out prematurely; the inferior fuel has high paraffin and sulfur content, which will produce engine Damage; after the daily operation, the fuel tank should be filled with fuel to prevent water droplets from forming on the inner wall of the tank; before the operation, open the drain valve at the bottom of the fuel tank to release water; after the engine fuel is exhausted or the filter element is replaced, the air in the road must be drained.
Minimum ambient temperature 0°C-10°C-20°C-30°C
Diesel grade 0#-10#-20#-35#2. Management of other oils Other oils include engine oil, hydraulic oil, gear oil, etc.; different grades and different grades of oil cannot be mixed; different types of excavators The additives used for chemical or physical action added by the oil in the production process are different; it is necessary to ensure the cleaning with oil to prevent the inclusion of impurities; the oil label is selected according to the ambient temperature and use. For high ambient temperature, oil with high viscosity should be used. For low ambient temperature, oil with low viscosity should be used. The viscosity of gear oil is relatively large to adapt to large transmission load. The viscosity of hydraulic oil is relatively small to reduce liquid flow. resistance.
