How to deal with the abnormality of circulating pump of thermal oil heater?

29 Mar 2024

Dealing with abnormalities in the circulating pump of a thermal oil heater involves several steps, aimed at identifying the issue and applying the appropriate corrective measures. Here’s a general approach:

1. Identify the Symptom: Common abnormalities include unusual noises, overheating, reduced flow rate, leakage, or vibration. Understanding the symptom helps in pinpointing the underlying issue.


2. Check Electrical Components: Inspect electrical connections, fuses, and the motor for any signs of damage or failure. Electrical issues can often cause the pump to malfunction.


3. Inspect Mechanical Parts: Look for signs of wear or damage on the pump’s mechanical components, such as the impeller, bearings, and shaft seal. Mechanical degradation can reduce pump efficiency or cause failure.


4. Examine the Thermal Oil Quality: Deteriorated oil can cause excessive wear or clogging. If the oil is degraded or contaminated, it may need to be replaced.


5. Verify Flow and Pressure: Ensure that the pump is operating within its designed flow and pressure range. Abnormalities in these parameters can indicate issues with the pump or the system it serves.


6. Lubrication: Check if the pump and its components are properly lubricated. Inadequate lubrication can lead to increased friction and wear.


7. Check for Blockages or Leaks: A blockage in the system can cause the pump to work harder than necessary, potentially leading to overheating and failure. Similarly, leaks in the system can reduce the efficiency of the thermal oil circulation.


8. Monitor Operating Temperature: Excessive temperature can damage the pump’s components. Ensure the pump is operating within the temperature limits specified by the manufacturer.


9. Routine Maintenance: Regular maintenance according to the manufacturer’s guidelines can prevent many common pump issues.


10. Consult Manufacturer’s Guide: For specific abnormalities, consult the pump manufacturer’s troubleshooting guide, as it will have tailored advice for their equipment.

If the problem persists or if there’s uncertainty about the cause or the solution, it’s advisable to consult a professional. Regular maintenance and timely addressing of any signs of wear or malfunction are key to preventing major issues with circulating pumps in thermal oil heaters.
