What are the causes of magnetic pump overloads

The magnetic pump is a motor-driven pump with high sealing performance, and other pump products that also use electricity to drive the same risk of overload, from past experience with pumps, magnetic pump overload causes most of the improper operation, in addition to the unexpected conditions caused by the pump personnel should always monitor the pump operating parameters, in the event of overload or other abnormalities in time to stop the pump to deal with.

Magnetic pump in the presence of overload, the external manifestation of the fault is generally frequent tripping, shaking during the operation process becomes abnormal violent, water drainage pulse increases and so on. In this regard, the user should know the reasons for magnetic pump overload in order to target the overhaul treatment, in the pump industry to make the relevant reasons to sort out the introduction.

1, voltage: some areas of the voltage can not reach the standard voltage, resulting in the magnetic pump motor in the stator winding current increase, the current is not stable will trigger overload. This situation often occurs in remote areas, with the development of society, there are less such cases.

2, selection errors: magnetic pump model specifications are rich, for transport conditions and parameters need to choose a different calibre pump type, but if the model performance is lower than the actual needs of transport, resulting in excessive operation during transport, will lead to overload. Therefore, it is recommended that the selection of models in collaboration with professional and technical personnel.

3, blockage: magnetic pumps and pipeline pumps are used to handle liquids that do not contain particulate debris, including corrosive liquids, if the transported medium contains fibres or particulate matter leading to blockage of the pump cavity, the motor will gradually overload, and there is a risk of grinding through the seal ring, it is recommended that the correct use of magnetic pumps according to the standard.

4, component wear: any pump after a long period of use are difficult to avoid wear or aging, the need to replace these bad components, the correct approach is to regularly check the state of the internal wear parts, usually recommended once a year for a comprehensive inspection.

In summary, there are several common causes of magnetic pump overload, and the corresponding treatment is not complicated, it is recommended to arrange for personnel with maintenance skills to deal with, to avoid improper operation leading to the expansion of damage.
