Caused the "Inability of excavator boom"
1 Excavator oil circuit is blocked.
2 There is a leak in the oil circuit, causing the excavator's arm to fail.
3 Shanhe excavator boom arm and cylinder leaks inside.
4 In addition to the above reasons, there may be an internal leakage in the hydraulic cylinder of the excavator boom, resulting in the failure of the excavator boom.
Excavator arm failure detection method:
1 First of all, to know if the excavator is obstructed by the oil path, the master excavator can remove the excavator tubing, excavator boom slide valve and valve stem and other related components to clean, in the oil The road was also cleaned, and the air inside the tubing was removed, and then assembled. In the process of working to see if the excavator's big arm failed, the fault phenomenon still existed. If it did not exist, the cause of the excavator's lack of power was the excavator oil path. block.
2 Excavator oil leakage, you can check whether the excavator parts have drip, or that there is no other failure performance in addition to the excavator boom no power phenomenon. Under normal circumstances excavator tubing leakage may be due to the excavator The seal has failed, or the excavator's oil temperature is too high, the excavator assembly is poor, and the excavator's pipe joint clearance is too large.
3 The excavator boom slide valve and the inner leakage of the cylinder are not easy to check out under normal circumstances. Therefore, some auxiliary methods are needed to judge, so as to eliminate the failure of the excavator boom.
4 To know if the excavator's boom does not have force due to leakage in the hydraulic cylinder of the excavator's boom, you can first receive the piston of the excavator boom cylinder at the bottom, and then remove the rodless cavity tubing, so that the boom cylinder has The rod cavity continues to be filled with oil. If there is a large amount of working oil leaking out of the rodless tubing port, the reason for the failure of the excavator boom is that the excavator is leaking inside the hydraulic cylinder of the boom.
