Common problems with magnetic pumps
The problems caused by cavitation in magnetic pumps: The main reasons for cavitation in pumps are high resistance in the pump inlet pipe, excessive gas phase in the conveying medium, insufficient pump filling, and insufficient inlet energy head. Cavitation poses the greatest threat to pumps. When cavitation occurs, the pump vibrates violently and the balance is severely disrupted, leading to damage to the pump bearings, rotor, or impeller. This is a common cause of magnetic pump failure.The main magnetic pump product names of China magnetic pump Network include:CQB-L vertical magnetic-driving pipe centrifugal pump，CQCB type stainless steel insulation magnetic pump，CQF fluorine plastic magnetic pump，CQG type high temperature resistant magnetic-driving pump，CQG type vertical magnetic pump
No medium or low flow rate of conveying medium: causing dry friction between the rotor spindle and the stable bearing, and burning the bearing. Magnetic pumps provide lubrication and cooling to sliding bearings through the conveying medium. Without an inlet or outlet valve, the sliding bearings may be damaged due to high temperatures caused by the lack of conveying medium lubrication and cooling.
Isolation sleeve damage: The magnetic coupling of the magnetic pump is cooled by the medium conveyed by the pump. If there are hard particles in the medium, it is easy to cause scratches or punctures on the isolation sleeve. Sometimes, improper maintenance methods may also cause damage to the isolation sleeve.
