Safety protection device for hydraulic system of four-column Hydraulic Press
- (1) After the main cylinder of the four-column hydraulic press moves up to the top position, it has a supporting function. It is beneficial to safely take out the pressed workpiece, reduces the working intensity and improves the working efficiency.
- (2) The system has a pre-unloading function. After the pressure holding is completed, the main cylinder does not move upwards. After the pre-unloading function, the pressure in the upper cavity of the main cylinder of the four-column hydraulic press can be released in advance, effectively reducing the pressure impact and avoiding noise pollution. .
- (3) When the four-column hydraulic press ejects the cylinder to push the workpiece down, due to the cylinder’s own weight, the downward speed is relatively fast, which may cause a vacuum phenomenon in the upper cavity of the four-column hydraulic cylinder. At this time, the suction valve can be used to quickly replenish oil.
- (4) The four-column hydraulic system is equipped with a filter device and an alarm device for excessive oil temperature, which can detect the quality and temperature of the oil in time to prevent abnormal conditions during work.
