Magnetic pumps are widely used in petroleum, chemical, pharmaceutical, electroplating, environmental protection, water treatment, film and television printing, national defense and other departments to pump flammable, explosive, toxic and valuable liquids. They are ideal pumps for creating leak free, pollution-free and civilized workshops and factories.
Operational precautions:
1. Prevent particles from entering
(1) No ferromagnetic impurities or particles are allowed to enter the magnetic drive and bearing friction pair. (2) After conveying media that are prone to crystallization or precipitation, it is necessary to rinse them in a timely manner (pour clean water into the pump chamber after stopping the pump, and discharge it clean after running for 1 minute) to ensure the service life of the sliding bearings. (3) When conveying media containing solid particles, it should be filtered at the inlet of the pump flow pipe.
2. Prevent demagnetization
(1) The magnetic torque cannot be designed too small. (2) It should be operated under the specified temperature conditions and it is strictly prohibited for the medium temperature to exceed the standard. A platinum resistance temperature sensor can be installed on the outer surface of the magnetic pump isolation sleeve to detect the temperature rise in the annular gap area, so as to alarm or shut down when the temperature exceeds the limit.
3. Prevent dry friction
(1) No idling is allowed. (2) It is strictly prohibited to evacuate the medium. (3) When the outlet valve is closed, the continuous operation time of the pump shall not exceed 2 minutes to prevent the failure of the magnetic drive due to overheating.
