[Excavator Maintenance] Several Basic Principles Need To Be Done!
Reduce the effects of temperature
In the excavator work, the temperature of each component has its own normal range. Generally, the temperature of the coolant is 80-90 ° C, and the temperature of the hydraulic fluid of the hydraulic transmission system is 30-80 ° C. Below or above this range will accelerate the wear of the parts, causing deterioration of the lubricating oil, resulting in changes in material properties and the like.
Therefore, you should pay attention to check the working condition of the cooling system. Water-cooled machinery must be inspected before work every day, adding coolant.
Reduce various corrosive effects
Corrosion of the metal surface will not only affect the appearance and normal operation of the excavator, but also affect the components inside the excavator. Rainwater and chemicals in the air can enter the inside of the machine, accelerating equipment wear and increasing equipment failure.
Therefore, in use, management and operation personnel should take effective measures according to the local weather conditions and air pollution at that time, as far as possible to prevent the intrusion of chemical components in rainwater and air into the machine, and minimize the operation in the rain.
Guarantee normal working load
The size and nature of the excavator's working load have an important impact on the loss process of the equipment. In general, when other conditions are the same, the stable load is less worn than the dynamic load, the failure is less, and the life is low.
Engines operating under normal load have a lower failure rate and a longer life. Conversely, in an overloaded engine, the failure rate is significantly increased and the life expectancy is reduced compared to the design specifications.
