What are the reasons why the four-column hydraulic press does not return

The scope of application of four-column hydraulic press is relatively wide, in the process of use, due to human failure or disrepair, the equipment will not return or return slow failure, four-column hydraulic press does not return and the solution is:

1, check the oil gauge, observe the return oil pressure is enough, not enough, need to adjust the pressure of the relief valve. If not, check whether the hydraulic valve is blocked and whether the hydraulic pump is faulty.

2. If the four-column hydraulic press has enough pressure, check whether the cylinder control valve has electricity and cannot supply hydraulic oil.

2, if the return is slow and there is no pressure, the return oil inlet solenoid valve is no power or stuck, or the plug-in is stuck.

3. The return oil solenoid valve has no power or is stuck, and the plug-in is stuck.

4, hydraulic cylinder string oil, resulting in direct flow of hydraulic oil back to the tank, so that the cylinder can not return.

In this case, the hydraulic system can be checked, the pipeline and hydraulic components of the control cylinder can be checked, and the specific reasons for the four-column hydraulic press not to return can be found.
