Reasons for the inability of the piston rod of the four-column hydraulic press and its elimination methods

Four-column hydraulic presses are widely used in riveting, embossing, forming, shallow stretching and other processes of hardware or hardware parts. It is inevitable that there will be failures during use. How to solve the problem when the piston rod of the four-column hydraulic press cannot move? The following will be analyzed and excluded by Shanghai WORLD Press Machine of WORLD Press Machine Machinery:

Fault phenomenon: insufficient pressure.

Reason analysis: 1. The oil did not enter the hydraulic cylinder

2. The reversing valve is not reversing

3. The system does not supply oil.

Remedy: 1. Check the reason why the reversing valve is not reversing and eliminate it.

2. Check the cause of the hydraulic pump and the main hydraulic valve and eliminate it.

Reason analysis: 1. There is oil but no pressure. The system is faulty, mainly the pump or relief valve is faulty. Internal leakage, the piston and the piston rod are loose, and the seal is seriously damaged.

Remedy: 1. Replace or check the failure cause of the overflow valve and eliminate it.
