When using pipe bending machine equipment, sometimes you don’t know how to solve some small problems because you don’t know much about the equipment. You can learn about our tips. After discovering the problem, it will be easy to solve it. I hope it can be helpful to you.
Serial number |
Fault |
Cause |
Solution |
1 | Press the motor start button, but the motor does not turn | A. Low power supply voltage or phase loss
B. Control circuit is not conducting C. Fuse is blown |
A. Check the 380V power supply voltage
B. Check whether the thermal relay and safety switch are turned on C. Check the fuse |
2 | Press the motor to start
The button starts the motor, The oil pump has no oil output |
Motor reverse | Adjust the motor wiring |
3 | When in working state, the system pressure cannot be adjusted, the oil cylinder does not move or does not move in place, and the speed is slow. | A. Oil filter or pipeline is clogged
B. Overflow valve core is stuck |
A. Clean the blockage
B. Repair the overflow valve |
4 | The system pressure is normal,
The cylinder does not move or The speed is slow and not in place |
A. Solenoid valve is stuck
B. Throttle valve flow is too small |
A. Repair solenoid valve and throttle valve
B. Adjust flow |
5 | Severe pressure fluctuations, abnormal noise, and cylinder creep | A. Air enters the system and the oil level is too low
B. The inside of the oil cylinder is roughened C. The solenoid valve has poor contact |
A. Add hydraulic oil
B. Repair the cylinder C. Check the wiring of the solenoid valve |
6 | Some actions are not performed | A. The corresponding electromagnet is stuck
B. The corresponding electromagnet control is out of order |
A. Repair solenoid valve
B. Check electrical circuit |
7 | Works slowly,
No pressure |
A. The relief valve adjustment pressure is too low
B. The seal is damaged |
A. Adjust the overflow valve pressure
B. Replace the seal |
8 | The inner side of the bent part of the bent pipe is wrinkled | A. Mold wear
B. Pressing mold is not in place C. Bending radius is too small or the elongation performance of the pipe material is poor |
A. Replace the mold
B. Adjust the pressing mold C. Increase the bending radius or increase the wall thickness of the pipe or choose a material with good elongation performance |
