In the electroplating industry, the application of magnetic pump can be said to be very found and popularized. whether it is the circulation of chemical pharmaceutical industry or the use of electroplating filter, magnetic pump is the first choice for the filtration cycle of pharmaceutical liquid, and it will not leak water in shaft seal because of its corrosiveness, nor will it cause the leakage of starting and burning shaft seal because of crystallization problem. However, the problem of concession will be encountered in the process of use. today, let's discuss it together to greatly reduce the maintenance cost of our enterprise.

Five common problems of electroplating circulating pump.

The main results are as follows: 1. The magnetic pump vibrates greatly.It may be caused by cavitation, and the main causes of cavitation erosion of magnetic pump are large resistance of pump inlet pipe, more gas phase of conveying medium, insufficient filling pump, insufficient energy head of pump inlet and so on. Cavitation is the most harmful to the pump. When cavitation occurs, the pump vibrates violently and the balance is seriously damaged, which will lead to damage to the bearing, rotor or impeller of the pump.

2. The pump shaft is broken. The shaft of the magnetic pump is made of 99% alumina porcelain. The main reason for the fracture of the shaft is that the shaft is twisted due to the empty 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 worn seriously to prevent the pump from breaking, which is the main way to avoid the idle operation of the pump.

3. The isolation sleeve is damaged. 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 scratches on the isolation sleeve, and sometimes it may cause damage to the isolation sleeve if the maintenance method is improper.

4. Insufficient lift. The causes of this failure are as follows: there is air in the conveying medium, the impeller is damaged, the rotational speed is not enough, the proportion of conveying liquid is too large, and the flow rate is too large.

5. Insufficient flow. The main reasons for insufficient flow are: impeller damage, insufficient rotational speed, high lift, sundries blockage in the pipe and so on.
