What are the common faults during the operation of carbon dioxide cryogenic pumps?

Common faults include excessive vibration, abnormal noise, insufficient flow, large pressure fluctuations, etc. These faults are usually caused by wear, corrosion, foreign matter intrusion or improper operation. For example, impeller wear can lead to reduced pump efficiency; seal failure can cause leakage; foreign matter entering the pump can damage the impeller or bearings. Therefore, regular maintenance and care are essential to prevent failures.
