How to exclude the slow action of the excavator - check whether the excavator is slow

01 Hydraulic system

Hydraulic system is one of the power systems of excavator. If the excavator vehicle runs slowly, the hydraulic system should be checked to see whether there is regular maintenance and whether the hydraulic oil is regularly replaced. Expired hydraulic oil will not only affect the performance of the excavator, but also corrode the hydraulic wall of the excavator. At the same time, it is necessary to check whether the hydraulic oil circuit and the oil return filter element are blocked.

02 The engine power is too low

Like the hydraulic system, the engine is also one of the power systems of the excavator. Low engine power will lead to low output power, and then the excavator will stall, making the excavator move slowly.

If the engine output power is too low or insufficient, please analyze the engine output combined with DX data, whether all cylinders can work at the same time; Check whether the engine is black smoke, if the fuel injector wear is serious, it will also lead to a reduction in engine power.

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 lubriing 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.
