Fault performance:
When working on the construction site, the Kobelco excavator suddenly appeared the fault of "the excavator has no power to walk"
The possible reasons for the failure of Kobelco excavator are as follows:
1. The spool of the solenoid valve is stuck
2. Check whether the hydraulic oil is too dirty
3. The pump liner and the plane have internal leakage and cannot reach the pressure
4. There is air in the oil pipe, which leads to poor walking force
5. The traveling pressure needs to be adjusted
6. The valve is not tightly closed inside
7. The mismatching of hydraulic pump pressure, data and flow will also cause the failure of excavator walking force
Maintenance and inspection methods of walking force failure of Kobelco sk350lc-8 excavator:
1. Clean the valve core of the solenoid valve
2. Check the hydraulic oil filter core
3. If the hydraulic oil becomes dirty, replace it in time
4. Exhaust the air from the oil pipe
5. Adjust the travel pressure
6. Pay attention to the sealing inside the valve
7. Use a professional debugging platform to debug the pressure, data and flow of the hydraulic pump
