Some common fault cases of Sany 750 excavator:
Case 1:
Fault phenomenon: The excavator moves slowly, especially in excavation and rotation.
Fault cause: After inspection, it was found that the internal wear of the hydraulic pump was serious, resulting in insufficient hydraulic oil flow and reduced pressure.
Solution: Replaced a new hydraulic pump, cleaned and debugged the hydraulic system, and restored normal operation.
Case 2:
Fault phenomenon: After the engine was started, the hydraulic system of the excavator did not move.
Fault cause: After inspection, it was found that the drive shaft of the hydraulic pump was broken and could not transmit power.
Solution: Replaced a new drive shaft, and inspected and reinforced related components.
Case 3:
Fault phenomenon: After the excavator worked for a period of time, the oil temperature was too high and the action was stuck.
Fault cause: The hydraulic oil radiator was blocked and the heat dissipation effect was poor, which caused the oil temperature to rise and affected the working performance of the hydraulic pump.
Solution: Cleaned the radiator, replaced the hydraulic oil, and solved the problems of high oil temperature and stuck action.
It should be noted that the specific fault phenomenon and cause may vary due to factors such as the usage environment and maintenance conditions.
