Common Failures and Solutions for tubular solenoidI. Common Failures of tubular solenoid
Poor Wiring
Poor wiring is one of the most common failures in DC solenoid. Incorrect or loose connections can prevent the push-pull tubular solenoid from operating properly. Common causes include damaged terminal boards, loose connectors, or missing coil connections.
Coil Burnout
Prolonged continuous operation or excessive heat can cause the coil’s insulation to degrade, leading to short circuits or burnout. Manufacturing defects in the coil itself can also result in premature failure, rendering the electromagnet inoperative.
Loose Iron Core
A loose iron core reduces the effectiveness of the magnetic circuit, resulting in a significant decrease or loss of magnetic force. This may be caused by long-term vibration and wear, loose fasteners, or design/manufacturing defects.
II. Solutions
Fixing Poor Wiring
Inspect the terminal board and connectors for damage.
Reconnect the coil leads according to the wiring diagram, ensuring firm contact and no oxidation.
Replace any damaged terminal boards or connectors if necessary.
Addressing Coil Burnout
Measure coil resistance with a multimeter to check for open or short circuits.
Inspect the coil for signs of discoloration, charring, or burnt odor.
If burnout is confirmed, replace the coil with a new one and verify that the supply voltage and current match the rated specifications to prevent recurrence.
Repairing a Loose Iron Core
Tighten the iron core fasteners or add locking measures.
Replace the iron core if it is severely worn or has structural defects.
After repairs, conduct a power-on attraction force test to ensure magnetic performance meets the required standard.
III. Maintenance and Care Recommendations
To extend the service life of the electromagnet and reduce the likelihood of failures, regular maintenance is essential:
Surface and Structure Cleaning
Regularly remove dust, oil, and debris from the electromagnet surface to ensure smooth heat dissipation.
Coil Condition Check
Inspect the coil for overheating, insulation degradation, or abnormal resistance.
Iron Core and Connection Inspection
Ensure the iron core and all fasteners are secure and free from wear, and terminals are firmly connected without corrosion.
Circuit Integrity Test
Check the power supply lines for damage, breakage, or poor insulation.
Conclusion
Common issues with tubular solenoid include poor wiring, coil burnout, and loose iron cores. By following standardized inspection and repair procedures, as well as performing regular maintenance, the service life of the electromagnet can be significantly extended, and stable performance ensured. It is especially important to note that electromagnets are precision electromagnetic components — repairs should be performed by qualified professionals to avoid further damage or safety risks.
