How to solve the problem of slow action of excavator -- check whether the parts are moving slowly:

When performing a single movement, the movement is slow, including walking, arm lift, turn, flip and so on. If it is a single operation such as walking, reversing, raising the arm and collecting the bucket, the speed is relatively slow. For example: the safety valve pressure of excavator related parts is too low (need to be detected); Pump, low pressure sensor, multi-way valve failure; Related solenoid valve failure, spool issued.

01. The component is faulty

The action component itself in the process of execution information receiving poor or poor contact, or related components of overflow valve pressure too low (overflow valve can control the overall pressure, if there is a hydraulic system will overflow) than can withstand the pressure relief valve), excavators can by hitting parts for repair, see if there's any loose screws or pressure testing.

02. The conduction process is faulty

That is, a fault occurs in the process of instruction transmission, which hinders the transmission of instruction signals. Therefore, you can focus on checking the pump, low pressure sensor and multi-way valve condition to see if there is a fault.

03. The operation center is faulty

That is, the central fault of the command delivery center of the excavator leads to the failure of signal delivery. This situation is generally more complex and requires professional maintenance guidance. All excavators can carefully check whether the relevant solenoid valve is faulty.

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.
