What are the reasons for a magnetic pump sticking?
Thread Content
Fluorinated magnetic pumps are used on-site, with a flow rate of 12.5 m3/h and a head of 20 meters; the medium is clean water without any impurities, and the operating temperature is at room temperature. There is no dry grinding due to lack of fluid; the installation method is backflow, and the impeller does not experience dry grinding or expansion. When the magnetic pump is turned on, it can operate normally for a minute, after which the pump protector suddenly cuts off the power and the pump freezes up immediately. It can’t be rotated even with hands. There is no motor overload, and the medium is clean water.
Bulging of the internal magnet drum is common; other issues include deformation of the isolation sleeve and jammed impellers, etc
The medium is clean water, and the inner drum is bulging – it’s impossible! I took it off to check, and the isolation sleeve wasn’t deformed or anything.
Does anyone know the reason?~~~
Sliding bearing damage caused by voids or foreign particles in the medium!
They’re all hugging each other; there’s no problem at all, it’s really amazing
Backflow type; no dry grinding due to lack of liquid, normal clean water without impurities.
No, there is pressure at the beginning, so there must be water.
