What are the precautions for the maintenance of the hydraulic system of the 1000 ton hydraulic press?

1. When overhauling the parts in the hydraulic system of the 1000-ton hydraulic press, the operation can only be carried out after the skilled personnel understand its principle and performance;
2、四柱液压机液压系统所能承受的压力为25MPa。若工作压力长时间超过额定压力范围，就会使机械部件遭到破坏，造成损失。该数一般在验收完后就会调好，因此一般不允许随意调整。 

3. Maintenance1000 tonsWhen the parts in the hydraulic system of the hydraulic press are used, the pressure head should be implemented on the pad iron to make the lower chamber pressure zero;
4. Turn off the motor oil pump of the hydraulic press during maintenance.
