Trouble Analysis of Four-column Hydraulic Press

Trouble Analysis of Four-column Hydraulic Press

1) The pressure of the four-column hydraulic oil pump is low. When the slider runs down, the bottom of the bottom has been opened, plus the weight of the slider itself, the slider moves down, but when it goes back again, because the pressure of the oil pump is low, the slider can be raised.

2) There is a problem with the solenoid valve of the four-column hydraulic press. When there is a problem with the valve assembly (solenoid valve, plug-in), the slider cannot return.

3) When there is a problem with other solenoid valves or components connected to the system, the slider cannot return because it cannot form an effective return pressure.

4) When the filling valve cannot be opened, the slider of the four-column hydraulic press cannot return, but the system will have a good pressure at this moment, which is very simple to judge.
