Common Failures and Solutions for Magnetizers

End-to-End Solution for Magnetization Automation

Magnetizers may have various failures during long-term use, and timely detection and treatment of these problems is essential to ensure production efficiency. The following are the common failures and solutions:

Power supply failure:

Phenomenon: The magnetizer cannot be turned on and the power indicator does not light up.
Causes: broken power cord, loose plug, damaged power switch, blown fuse.
SOLUTION: Check power cord connections, replace damaged switches and fuses, and make sure grounding is good.

undefinedundefined

Poor magnetization:

Phenomenon: Insufficient magnetic field strength after magnetization, unstable magnetic properties.
Causes: Insufficient magnetizing voltage, coil damage, capacitor aging, improper material selection.
Solution: Increase the magnetizing voltage, check the insulation of the coil, replace the aging capacitor, and make sure the material matches the equipment.

undefinedundefined

Control circuit failure:

Phenomenon: The magnetization process is unstable and the parameter display is abnormal.
Cause: Relay failure, SCR damage, aging control chip.
Solution: Check control components, replace damaged relays and SCRs, and recalibrate control parameters.

undefinedundefined

Security Protection Trigger:

Phenomenon: The equipment stops automatically and the protection indicator lights up.
Cause: Over-current, over-voltage, over-temperature protection triggered.
Solution: Check the load condition, ensure good heat dissipation, and adjust the magnetization parameters to a safe range.

JiuJu magnetizer has perfect self-diagnostic function, which can monitor the operation status of the equipment in real time, and discover and warn potential problems in time. JiuJu magnetizer adopts modular design, key components such as capacitors, SCRs, etc. are imported brands, which greatly reduces the failure rate.

Regular Maintenance Recommendations: JiuJi magnetizers are recommended to check the capacitor performance monthly, clean the inside of the equipment quarterly, and perform full calibration and maintenance annually. JiuJu magnetizer provides professional after-sales service, including equipment installation and commissioning, operation training, fault repair and other one-stop services.
