Dadonghai Pump Wuxi Co., Ltd. is a professional centrifugal pump manufacturer. When selecting centrifugal pumps for customers, our pump manufacturers will provide perfect pre-sales services such as centrifugal pump models, centrifugal pump prices, etc. for customers' reference, and our pump manufacturers can provide customers with customized pump products. This information is about how to prevent the motor of centrifugal pump from being burnt:

The motor may fail during operation, and burning is one of them, which not only affects the normal work, but also increases the cost, causing us a lot of trouble. There are many reasons why the motor is burnt out, which is related to the quality of the machine itself and whether the centrifugal pump is used correctly.

After the power is turned on, carefully observe the working condition of the centrifugal pump. The outlet water should be connected evenly and the centrifugal pump can be used without vibration and noise. In case of sudden shutdown during operation, disconnect the power supply immediately and check the cause. The interval between two starts of the centrifugal pump shall be limited to the return of all water in the centrifugal pump. If it starts too early, the motor will be burnt due to excessive resistance and water hammer in the water pipe. In addition, if the centrifugal pump is installed in the well, it should be noted that the flow of the centrifugal pump should be consistent with the normal water yield of the well, otherwise it will form an empty machine and burn the motor.

In order to ensure the normal operation of centrifugal pumps, Dadonghai Pump Industry reminds everyone to pay attention to the following points before using centrifugal pumps:

1. Check whether the centrifugal pump motor winding is open circuit. The insulation condition can be measured with a 500V megohmmeter. When the insulation resistance is lower than 0.5 megohm, the centrifugal pump cannot be used.

2. Remove the filter screen and check whether the rolling pump shaft is sensitive. If not, adjust it before use.

3. Whether the selection of gate fuse capacity is appropriate, and other wires cannot be used to replace the fuse.

4. Turn on the power and check whether the impeller works normally (the power on time shall not exceed 3-5 seconds, otherwise the motor may be burnt out.
