1. The piston sealing ring of the die forging hydraulic press is aging and needs to be replaced in time to ensure that the sealing device is inside.
2. The oil seal is squeezed and needs to be trimmed in time and replaced if necessary.
3. Check the solenoid valve problem, check whether the power supply on the solenoid valve can be energized normally, and then check whether the magnet of the spool can operate normally without valve stuck
4. The solenoid valve of the die forging hydraulic press is faulty. First check the power connection, and also check whether the sealing ring of the hydraulic oil pipe is normal and free from damage.
The reason why the middle beam slides down on the die forging hydraulic press is usually these kinds. Users need not worry, check slowly and return to normal use.
