What is the Basic Principle of Maintenance of an Excavator?

With the rapid development of the national real estate industry and the rapid development of the construction industry, the demand for construction machinery from small excavator manufacturers has increased. However, due to the harsh working environment, construction machinery often fails and the service life is reduced. Generally speaking, Excavator Bucket Teeth Manufacturer's excavator maintenance includes the following two aspects.

First, keep the filter element in good maintenance. The function of the filter element is to filter impurities in the oil and gas channel 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 periodically according to the requirements of the (Operation and Maintenance Manual) Replace. When replacing the filter element, please check whether there is metal attached to the old filter element. If metal particles are found, it should be diagnosed in time and take corrective 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 mini 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, the 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. Our company has Bucket Rippers on sale.

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