Four-column hydraulic press does not return how to do?

If the four-column hydraulic press does not return, it may be caused by the following reasons:

1. Insufficient pressure or leakage of the hydraulic system: check whether the oil in the hydraulic system is sufficient and check whether there is leakage of the hydraulic pipeline.

2. Hydraulic cylinder piston seal damage: Check whether the hydraulic cylinder seal wear, cracks, etc., need to be replaced.

3. Hydraulic valve failure: Check whether the hydraulic valve is blocked, damaged, etc., and needs to be replaced.

4. Hydraulic pump failure: Check whether the hydraulic pump is faulty and needs to be replaced.

The solution:

1. Check whether the oil is sufficient, whether there is leakage in the hydraulic pipeline, replenish the oil in time and repair the leak.

2. Replace the hydraulic cylinder seal.

3. Replace the hydraulic valve.

4. Replace the hydraulic pump.

If the above methods cannot solve the problem, it is recommended to contact professional maintenance personnel for maintenance.

1, there is no action and no pressure on the return trip, generally the solenoid valve that controls the pressure relief valve has no electricity and cannot supply the pressure oil;

2, there is no action pressure, generally the return oil inlet solenoid valve no power or stuck, or plug-in stuck, the other is the return oil solenoid valve no power or stuck, plug-in stuck.
