About the daily maintenance of the magnetic pump. Also pay attention to his daily use specifications. If the daily use is not in place, if the same damages his performance, it will be difficult to restore the original performance of the magnetic pump even if it is repaired later.
Guidelines for the use of magnetic pumps:
1. Prevent particles from entering
(1) Ferromagnetic impurities and particles are not allowed to enter the magnetic drive and the bearing friction pair.
(2) It should be operated under the specified temperature conditions, and it is strictly forbidden 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 stop when the temperature exceeds the limit.
(3) When the outlet valve is closed, the continuous operation time of the pump shall not exceed 2min to prevent the magnetic drive from being overheated and lost.
2. Prevent demagnetization
(1) The magnetic moment cannot be designed too small.
(2) Rinse in time after conveying the medium that is easy to crystallize or precipitate (after stopping the pump, pour clean water into the pump cavity, and drain it after running for 1min) to ensure the service life of the sliding bearing.
3. Prevent dry friction
(1) Idling is strictly prohibited.
(2) It is strictly forbidden to evacuate the medium.
(3) When conveying media containing solid particles, it should be filtered at the inlet of the pump flow pipe.
