Maintenance method of excavator


In the construction of hydraulic excavator, according to the load requirements of the operation, the speed and load (flow and pressure) are inversely proportional. Simply put, the product of pump output pressure and flow rate is a constant, and the output power of the pump is constant or approximately constant; If the pump control system fails, the engine - pump - valve - load cannot be well realized under different working conditions. Optimize the matching state of the region, so that the excavator can not operate normally, so it is necessary to master the excavator control system produced by each manufacturer. For example, Daewoo EPOS system, Kato APC system, Komatsu CLSS system, etc. When handling faults, they are analyzed and confirmed from simple to complex. Combined with modern excavators, they are electromechanical and hydraulic integrated products with high technical content. Therefore, when dealing with faults, they generally start with the electrical system, then check the hydraulic system, and finally check the mechanical transmission system. When checking the hydraulic system, check it step by step from auxiliary oil-control oil-main oil-control element.

Advantage of Engine Cylinder Liner Kit

  • Greater resistance. Making liners separately from the engine block allows the use of special higher performance materials than those used for the construction of the block itself. Liners are generally made in special cast iron alloys containing elements with natural lubricating properties, like graphite. Other components are added like chrome, vanadium, and molybdenum to help ensure resistance to corrosion and wear caused by high temperatures.


  • Easier maintenance. When liners are worn they can be replaced more easily than changing an entire cylinder block.


  • Higher thermal conductivity. At operating temperatures the liners heat up more than the cylinders and must be able to expand in both diameter and length. If they were cast together with the cylinders, the resulting thermal loading would be high enough to fracture the materials.


  • Less risk of defects. The more complex a casting, the more difficult it is to achieve perfectly even surfaces with low residual stresses.
