Troubleshooting for Descent of Piston Rod in Hydraulic Press for Automotive Interiors

The main reason for the descent is generally due to leaks. Therefore, the first step is to diagnose the cause of the leak and identify the faulty points for appropriate treatment. You can try checking the following:

1. Check for Leaks in the Lower Chamber Balancing Valve or Back Pressure Valve:

• Inspect for any leaks in the balancing valve or back pressure valve in the lower chamber of the cylinder.

2. Inspect Axial Seals for Damage:

• Examine the axial seals of the cylinder for any signs of damage.

3. Check for Oil Seepage in the Cylinder:

• Investigate whether there is oil seepage in the cylinder, indicating potential damage to the piston seals.

By identifying and addressing the underlying causes of the leaks, you can rectify the issue and prevent further descent of the piston rod.
