Cause of Pressure Overloaded in Hydraulic Press MachineUpdate：2024-01-03 Hits：106
In daily work, we may encounter the problem of pressure overload in hydraulic press machine. How should we solve this problem?
1. When the mold mounting height of the hydraulic press machine is not adjusted properly or double materials appear, the press will be overloaded. At this time, the pressure in the hydraulic cylinder will rise sharply, and the pressure in the high-pressure chamber of the unloading valve will When the pressure in the back pressure chamber is greater than the pressure in the back pressure chamber, the piston is pushed downward to open the oil return port, which will allow the hydraulic oil to quickly return to the tank.
2. The slider will move up 20mm under the action of the balancer, thereby protecting the press and mold from any damage. At the same time, the pressure relay and travel switch act to cut off the clutch control circuit, causing the press to stop. The solenoid valve closes the air source and quickly discharges the air in the back pressure chamber of the unloading valve, so that the indicator light under "normal" conditions goes out, and the "unloading" indicator light lights up, as does the hydraulic press.
3. Although the pressure overload on the hydraulic press machine also has a protection system, if it exceeds the protection range, it will also cause great damage to the machine itself, so we must always follow the requirements of the specification when using it. operation to ensure that the hydraulic press machine can operate normally.
If you choose Goodsjack/Delishi hydraulic press machine, Please don't worry pressure overload, all hydraulic press machines with overload protector. Overload Protector is installed on the press machine in order to check the pressure of hydraulic cylinder inside slider. If the load exceeds the limit of press machine itself as machine stamping, Overload Protector will activate immediately, making the hydraulic pressure inside slider release in a short time. Also, to protect die and machine's structure, the position switch will send out a signal to suddenly stop the hydraulic press machine.
