Description

Overload Protector is equipped in Press machine to check hydraulic pressure of cylinder inside the slider. If happen overload, the hydraulic pressure of cylinder will be released immediately within 3/1000 seconds. When happen overload, in order to protect the press and die, the press will stop working immediately after receiving the signal from limit switch. After happen overload, the air will drive hydraulic pump to supply normal working pressure immediately and the press can work normal. It has pressure control valve inside of overload protector, which can adjust hydraulic pressure automatically and eliminate the impact of rising pressure (which cause by oil temperature rise) in pressing process. May select different types of components and control units base on the different types and specifications of press machines.
