The operation monitoring of a high corrosion-resistant and wear-resistant multi-stage pump is an ongoing process involving the inspection and maintenance of multiple parameters. Through daily checks, regular maintenance, and exception handling, the normal operation of the multi-stage pump can be ensured, improving production efficiency and reducing the failure rate. It is recommended that operators be familiar with the monitoring key points and procedures to ensure the safe and stable operation of the multi-stage pump.

I. Overview

High corrosion-resistant and wear-resistant multi-stage pumps are widely used in the chemical, pharmaceutical, and metallurgical industries, with stable performance, large flow rate, and high head. To ensure the normal operation and extend the service life of the multi-stage pump, real-time monitoring of its operation is crucial.

II. Operation Monitoring Key Points

1. Flow Monitoring: Flow rate is one of the important indicators for evaluating the performance of a multi-stage pump. Real-time monitoring of the flow rate through a flow meter ensures that it is within the design range.

2. Pressure Monitoring: Pressure fluctuations can lead to unstable pump operation. The pressure gauge readings should be checked regularly to ensure that they remain stable within a certain range.

3. Speed Monitoring: The speed affects the flow rate and head of the pump, and the motor speed must meet the design requirements.

4. Temperature Monitoring: Monitor the temperature of the pump body and bearings to prevent overheating due to overload or friction.

5. Vibration Monitoring: Excessive vibration can damage the pump. Monitor the pump's vibration using a vibration sensor and make adjustments in a timely manner.

6. Leakage Check: Check for leaks at the pump body, flanges, and other connections. Address any leaks immediately.

7. Noise Detection: Excessive noise may indicate a problem with the pump. Check regularly and take measures to reduce noise.

III. Daily Inspection and Maintenance

1. Regularly check if the pump fasteners are loose.

2. Check the wear and tear of the seals and replace them in a timely manner.

3. Check the lubrication of the bearings to ensure that the bearings operate normally.

4. Clean impurities inside the pump casing to keep the inside of the pump clean.

5. Check the electrical system to ensure that the motor is operating normally.

IV. Handling of Abnormal Situations

1. If abnormal parameters such as flow rate, pressure, and temperature occur, the cause should be immediately identified and measures taken.

2. If excessive pump vibration or abnormal noise is detected, the machine should be stopped for inspection and troubleshooting.

3. If a leak is found, the machine should be stopped and the seals tightened or replaced.
