What to do if the magnetic steel of the magnetic pump is demagnetized
When the magnetic steel of the magnetic pump is demagnetized, the following measures can be taken for maintenance:
1. Inspection and evaluation
Check the demagnetization of the magnetic steel: Use a magnetic tester to test the magnetic steel of the magnetic pump to determine whether the magnetic steel has been demagnetized and the severity of the demagnetization.
Evaluate the maintenance plan: According to the degree of demagnetization of the magnetic steel and the use of the pump, evaluate whether it is necessary to replace the magnetic steel or try to restore the magnetism.
2. Maintenance method
Replace the magnetic steel:
When the magnetic steel is severely demagnetized or completely loses its magnetism, it is necessary to replace it with a new magnetic steel.
Select magnetic steel of good quality and ensure that it meets the technical requirements of the magnetic pump.
When replacing the magnetic steel, it should be strictly followed in accordance with the operating specifications to ensure that the magnetic steel is correctly installed and firmly fixed.
Demagnetization repair:
For slightly demagnetized magnetic steel, you can try to use the demagnetization repair method to restore its magnetism.
Use an electromagnetic demagnetizer or a magnetic field remagnetization device to treat the magnetic steel, and generate a reverse magnetic field to offset the original demagnetization effect, thereby restoring the magnetism of the magnetic steel.
When performing demagnetization repair, it is necessary to control the demagnetization force and time to avoid secondary damage to the magnetic steel.
Cleaning and maintenance:
Regular cleaning and maintenance of the magnetic pump can extend the service life of the magnet and reduce the possibility of demagnetization.
Cleaning the dust and dirt on the surface of the magnet and keeping it clean will help improve the magnetization effect.
3. Precautions
Safe operation: Before repairing, the power supply of the magnetic pump should be cut off and all related equipment should be disconnected to ensure the safety of the repair process.
Environmental control: The ambient temperature and humidity should be controlled during the repair process to avoid the magnet affecting the repair effect due to excessively high or low temperature.
Tool selection: Use appropriate repair tools and testing equipment to ensure the accuracy and reliability of the repair work.
Test verification: After the repair is completed, the magnetic pump should be tested and verified using a magnetic tester to ensure that the magnet has restored normal magnetism and the pump's working performance meets the requirements.
4. Preventive measures
Control temperature: Keep the operating temperature of the magnetic pump within a reasonable range to avoid demagnetization of the magnet due to excessive temperature.
Optimize operating conditions: Ensure that the magnetic pump operates under rated conditions to avoid long-term low head or idling operation.
Choose the right medium: Choose the right medium for transportation according to the technical requirements of the magnetic pump to avoid corrosion or damage to the magnetic steel.
Strengthen maintenance: Regularly check the magnetic condition of the magnetic pump, the wear of the sliding bearing, and the matching of the pipeline, etc., and find and deal with problems in time.
