When the servo hot forming press is working, the servo motor can automatically complete the conversion of torque and speed and energy optimization according to the change of pressure and speed, without the phenomenon of rotation, and it is obviously with advantages such as sensitive, energy-saving, environmentally friendly, safe, clean, quiet, use and maintain, and low-cost.
The spring of the filling valve of the main cylinder of the four-column hydraulic press is broken, and the sealing degree of the filling valve is not up to standard Solution: replace the spring and grind the sealing surface of the filling valve to ensure that there will be no leakage.
There are three common failures in the four-column hydraulic press system, which are the overheating oil temperature, air entering the system, and the oil pollution.
