Oil leakage in the loader working pump is one of the common faults. The most common reason is that the oil seal is damaged or aged, causing the leakage of hydraulic oil. In addition, there may be the following reasons:
1. The matching clearance between the oil seal and the bearing is too large
2. The connection between the parts of the loader working pump is loose
3. The hydraulic pipeline is aged or corroded
4. The seal at the bottom of the loader working pump is aged or damaged
When the loader working pump leaks, it needs to be repaired as soon as possible to avoid the leakage from aggravating the damage to the pump or other parts of the hydraulic system. Here are some common solutions:
1. Replace the oil seal
If the cause of the loader working pump leakage is the damage or aging of the oil seal, you can replace it with a new one. However, it should be noted that simply replacing the oil seal may not completely solve the leakage problem. If there are other reasons, repairs are also required.
2. Replace the seal
If the seal at the bottom of the loader working pump is aged or damaged, the seal needs to be replaced in time.
3. Strengthen the connecting parts
If the connecting parts between the parts of the loader working pump are loose, they need to be tightened or replaced again.
4. Replace the hydraulic pipeline
If the hydraulic pipeline is aged or corroded, it needs to be replaced.
III. Precautions
1. When replacing parts, select original parts or parts of equal quality that meet the requirements to ensure quality and performance.
2. Before repairing, the machine should be stopped for inspection, and repairs should not be carried out under power or power.
3. After repair, tests should be carried out to ensure that the system is operating normally and there is no leakage of hydraulic oil.
