What is the Maintenance Principle of the Excavator?

With the rapid development of the national real estate industry and the rapid development of the construction industry, China Excavator Company's demand for construction machinery has increased. However, due to the harsh working environment, construction machinery often fails and the service life is reduced. In general, the following is The maintenance of XCMG Excavator construction machinery brought by everyone mainly includes the following two aspects.

XCMG Excavator

Keep the filter element in good maintenance. The function of the filter element is to filter impurities in the oil and gas passages and prevent impurities from entering the system and causing failures. Use pure filter elements according to the requirements of the machine; all filter elements should be replaced periodically according to the requirements of the (Operation and Maintenance Manual) When replacing the filter element, please check whether there is metal attached to the old filter element. If metal particles are found, you should promptly diagnose and take improvement measures.

Second, grasp the selection and management of fuel, other engine oils and lubricants.

The working environment for the maintenance of construction machinery has changed, which means that the choice of fuel must also be changed, and different grades of fuel must be selected according to different environmental temperatures, with qualified quality, so as to prevent high-quality paraffin and sulfur content of high-quality fuel from damaging the fuel. Engine; Diesel To keep it clean and pollution-free, do not mix it with impurities, ash and water. A small excavator is briefly introduced, otherwise the fuel pump will wear out prematurely; before daily operation, open the drain valve at the bottom of the fuel tank to drain water. After operation, Fill the fuel tank with fuel to prevent water droplets from forming on the inner wall of the fuel tank. Other oils include engine oil, hydraulic oil, gear oil, etc.

The selection and storage of some oils are also the same as those of oil, and different grades and grades of oil cannot be mixed; in order to ensure that the grease is clean and to prevent the inclusion of impurities; choose different label oils according to the ambient temperature and use conditions. When the ambient temperature is high, the viscosity should be selected For larger oils, when the ambient temperature is low, you should choose an oil with a relatively low viscosity; the viscosity of gear oils is large to accommodate large transmission loads. Hydraulic oils have relatively low viscosity to reduce fluid flow resistance.

The role of lubricating oil (butter) is to reduce friction on the surface of the object, thereby reducing wear on moving surfaces and preventing noise. Use lithium-based grease g2-l1 because it has good abrasion resistance and is suitable for heavy loads. When refueling, please Try to squeeze out all the old oil and wipe it clean to prevent the sand from sticking.
