Seeking help with questions regarding magnetic pump
Thread Content
I would like to ask the experts: we have a high-temperature magnetic pump, and during operation the motor current suddenly dropped (from 36A to 14A). The flow rate is not displayed either; it is suspected that the motor is spinning idle while the pump shaft is not rotating； It works normally after restarting ； Everyone, please help analyze it. Thank you~~
It has been running stably up until now; it shouldn’t suddenly stop working, right?~~
No, its boiling point is 280°C, and its operating temperature is around 250°C~~
If it restarts normally, this rules out the possibility of the motor running idle as you mentioned, that is, problems with the rotor or a phase loss in the motor. The flow rate isn’t being displayed; it should be shown by the flow meter downstream. Is the pressure gauge on site working properly? It’s better to check with the process team to see if there are any instrumentation components upstream that can help monitor the situation, and to determine whether any process fluctuations are affecting the equipment.
