Bucket cylinders, hydraulic pumps, motors and other parts of the oil leakage, is a relatively common problem, then the excavator valve block at the hydraulic oil seepage and see the appearance of the appearance of no abnormalities, how do we face and solve this problem, the following briefly share the relevant knowledge.
First, excavator valve block oil leakage fault check:
1, first wipe the oil clean, start the machine work less than 3 minutes, the valve block bottom plate has begun to drip oil, as the valve block connected out of the pipe so few, so all the pipe joints re-twisted, the fault remains.
2, replace the new valve block, found that the oil leakage.
3, So, remove the solenoid valve block fixed screws, hang up the valve block, wipe it clean, and continue working. After a period of work, hurry over to check. Finally, find the oil leakage point. Originally, the valve block’s processing process holes caused the oil leakage. Unscrew the hexagonal screws in the process holes, mount a small O-ring, and tighten to eliminate the fault.
Finally, the result: very simple, add an O-ring to the process hole, troubleshooting. Handling problems need to be carefully observed. Sometimes, new parts will also have issues. Therefore, we must find ways to identify the cause of the failure. Some hydraulic parts, due to processing technology, need to have process holes. If you do not handle these process holes well, they will also cause oil leakage. Additionally, improper management of process holes may cause other faults.
