1. The magnetic pump bearing is damaged.
The bearing of CQB magnetic pump is made of high-density carbon. In case of water cut-off or impurities in the pump, the bearing will be damaged. If the coaxiality between the inner and outer magnetic rotors of the cylindrical coupling is not guaranteed, it will directly affect the service life of the bearing.
2. Insufficient lift.
The causes of this fault are: there is air in the conveying medium, the impeller is damaged, the rotation speed is not enough, the specific gravity of the conveying liquid is too large, and the flow rate is too large.
3. The magnetic pump shaft is broken.
The material of the pump shaft of CQB type magnetic pump is 99% alumina porcelain. The main reason why the pump shaft is broken is that the shaft is twisted and broken due to the idle operation of the pump and the dry grinding of the bearing. When disassembling the pump for inspection, it can be seen that the bearing has been seriously worn. The main way to prevent the pump from breaking is to avoid the pump from idling.
4. Insufficient flow.
The main causes of insufficient flow are: impeller damage, insufficient rotation speed, high lift, sundries blocking in the pipe, etc.
5. The magnetic pump cannot pump out liquid.
The failure of the magnetic pump to pump liquid is the most common fault of the pump, and there are many reasons.
First, check whether there is air leakage in the suction pipe of the pump, whether the air in the suction pipe is discharged, whether the liquid filled in the magnetic pump is sufficient, whether there are sundries in the suction pipe, whether the pump is reversed (especially after the motor is replaced or the power supply line is overhauled), and whether the suction height of the pump is too high. If the problem cannot be solved through the above inspection, the pump can be disassembled for inspection to see whether the pump shaft is broken, and whether the moving ring and static ring of the pump are in good condition, and whether the whole rotor can move axially. If it is difficult to move axially, check whether the carbon bearing is too tightly combined with the pump shaft.
