Analysis on Komatsu excavator has one side of the shoe can not move and can not go straight fault maintenance treatment
Posted: Oct 24th, '24, 04:07
Fault symptoms:
5600 hours excavator at the same time forward or backward two walking rod push as much to go straight, rotation in place sometimes one side of the track does not move, with the big arm to support the machine to change the direction of travel action is always one side of the track does not move.
Fault focus: the excavator can not go straight, a bit off.
One side of the excavator can not move and can not go straight fault analysis:
1 There is a problem with the central oil separator
2 Connect other pilot oil to your walk and try whether you can walk at the same time to determine whether the pressure of the walk leader is normal.
3 Then see if the back pressure of the excavator , that is, the oil filling port pressure of the rotary motor, is normal?
4. The hydraulic oil circuit is not clean, and the tiny dirt blocks the damping hole in the middle of a small piston in the safety valve, which can be removed from the safety valve to clean and eliminate the blockage of the damping hole.
What if the excavator can't go straight?
1 The pressure of the walking motor on the left and right sides of the excavator is inconsistent.
2 It is recommended to use a pressure gauge to detect the difference between the pressure values of the left and right walking motors. After the test, he can adjust the side with low pressure in the safety valve to the higher level, which can eliminate the problem that Komatsu PC60-7 excavator can not go straight.
3 If the pressure value of the walking motor on both sides of the excavator is detected to be the same, it may be that the flow rate of the plunger pump is not the same.
4 If the flow rate of the plunger pump is the same, Komatsu PC60-7 excavator can not go straight because of the problem of the excavator's linear control valve
