I believe that users who often use hydraulic presses have encountered such a problem that the servo hydraulic press can not rise normally because of the pressure, but many people do not know what is the reason for this, today Xiaobian will understand why the pressure of the hydraulic press can not rise.
1, the hydraulic meter is broken, replace the new hydraulic meter;
2, oil leakage. First carefully check the appearance of the machine there is no significant oil leakage phenomenon (hydraulic cylinder, hydraulic pipe, connection effect); If not, that is, the piston oil seal is damaged, this first put around, because unless it is really unable to find a solution will be opened off the hydraulic cylinder to change the oil seal ring;
3, common sense operation fault. Although this phenomenon is relatively simple, it should also cause the attention of the servo hydraulic press operator, such as the three-phase connection, the height of the oil tank is not hit the specified value, and the pressure regulating valve is not adjusted (that is, the relief valve is not adjusted). This phenomenon is generally presented in the first use of servo hydraulic press by new employees.
