Taking SDS-11032 as an example, the breakdown can be eliminated by the following methods when the bending machine starts without pressure.
1. Make sure there is enough hydraulic oil in the tank.
2. Detecting whether the connected power supply is 380V
3. Detect whether the motor is reversed.
4. If reversed, switch two of the power lines.
5. If the CNC system is in positive rotation, check whether the signal connection line of the CNC system is in good contact.
6. Detect whether the oil pump is damaged.
7. Detect whether the pressure gauge is damaged.
8. Check whether the pressure control valve has signal or blockage.
9. Check whether the proportional valve is blocked or not. Blocking will cause the slider to stop slowing down.
