When the hydraulic press leaks oil during operation, the reasons are analyzed as follows:
1. Check whether the hole cover of the hydraulic press is too thin. In this case, it is easy to deform after tightening the bolts. Check if there is oil leakage in the touch gap;
2. During the operation of the hydraulic press, if there is too much oil, a large amount of oil will accumulate on the shaft seal, contact surface, etc., causing leakage;
3. There is no oil return tank on the hydraulic box. In this case, the oil is stored on the contact surfaces such as the shaft seal and end cover, and leaks freely from the ground under the action of the pressure difference;
4. Improper maintenance technology. During the maintenance of the hydraulic press, oil leakage may be caused due to incomplete removal of dirt on the contact surface, improper selection of sealant, reverse sealing direction, and failure to replace the seal in time;
5. During the production process of the hydraulic press, the relevant castings are not annealed or treated to eliminate internal stress. After long-term use, it will deform, causing idling and causing oil leakage.
