Abnormal noise in the inlet pipeline of the magnetic pump
Thread Content
During operation, the magnetic pump experiences intermittent abnormal noises in the inlet pipeline. Phenomenon: 1. There is significant noise, but no obvious vibration at the site. 2. There is no significant fluctuation in the flow rate in the outlet pipeline of the magnetic pump. 3. Adjust the frequency of the magnetic pump motor’s inverter; the flow rate changes appropriately as the frequency rises or falls. I’m urgently asking fellow sailors if you have encountered similar situations and how you resolved them
Based on the poster’s description, operation and traffic are basically normal. From my personal experience, one possible reason is that the pump foundation or the mounting bolts might be loose； Second, it is possible that the pump bearings or the motor bearings are starting to fail ； Third, the wind shield at the back of the motor may be loose. Personal experience; please use with caution
Is there any fluctuation in pressure? What is the medium, and what is the temperature?
1. No significant pressure fluctuations. 2. Medium: carbon disulfide, boiling point 46.5°C; transmission temperature: 30°C; pressure: atmospheric pressure
If the boiling point at atmospheric pressure is 46.5°C, then the abnormal noise from the pump is caused by cavitation. Find ways to reduce the temperature of the inlet medium
