Analysis of Common Walking Deviation Problems of Excavators

1.There is something wrong with the hydraulic pump

Under normal circumstances, excavators are equipped with double pumps. Deviation during movement is often due to a malfunction of one pump. The simplest way to determine this is to swap the two high-pressure oil outlet pipes of the hydraulic pump. If the originally slow one becomes faster and the originally fast one becomes slower, it indicates that one of the pumps is faulty. Troubleshooting method: Remove the hydraulic pump, replace the damaged parts, and then debug it on the laboratory bench.

2. The safety valve of the walking motor is leaking oil

Oil leakage from the safety valve will cause the pressure within the system to be too low, resulting in insufficient rotational speed of the traveling motor and thus causing the vehicle to deviate. The troubleshooting method is: Replace the damaged safety valve of the walking motor; When making a judgment, the left and right walking motors can be safely swapped to see if they deflect when moving in the opposite direction.
