Key points of daily maintenance of magnetic pump

1.The shaft of the shaft breaking magnetic pump is made of 99% alumina porcelain or silicon carbide

The main reason for the shaft breaking is that the shaft is broken by dry grinding of the bearing due to the empty operation of the pump. When disassembling the pump for inspection, we can see that the bearing has been worn seriously. The main way to prevent the pump from breaking is to avoid the idle operation of the pump.

2.Bearing damage
The bearing of the magnetic pump is made of high-density carbon, which will cause damage to the bearing if the water is cut off or there are impurities in the pump. If the coaxiality requirement between the internal and external magnetic rotors of the cylindrical coupling is not guaranteed, it will directly affect the life of the bearing.

3.Insufficient lift
The reasons for this failure are: air in the conveying medium, impeller damage, insufficient rotational speed, excessive proportion of conveying liquid and excessive flow rate.

4.Insufficient traffic
The main causes of insufficient flow are: impeller damage, insufficient rotational speed, high lift, sundries blockage in the pipe, etc.

5.The magnetic pump can not produce liquid
The failure of the magnetic pump to produce liquid is easy to occur in the pump, and there are many reasons. First of all, we should check whether there is air leakage in the suction pipe of the pump, check whether the air in the suction pipe is discharged, whether the amount of liquid injected into the magnetic pump is enough, and whether there is debris blockage in the suction tube. You should also check whether the pump is reversed (especially after changing the motor or after the power supply line is overhauled), and pay attention to whether the suction height of the pump is too high. If the above inspection still can not be solved, the pump can be taken apart and checked 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 close to the pump shaft.
